Hey guys, Honda is getting respect in south Florida, I went to Miami for the weekend and raced many skis there, from the new Yamaha fzr not stock, sea doo's, gp 1300, kawis and I win most of the races, I lost to 2 rpx's and one of them was doing 78.1 on my gps and I only lost by 3 skis length, due to the waves he was jumping to much out the water, and a gp1300 by 1/2 of ski on the flat,,I figure that is better to tell you guys to whom I lost against than to tell you all the ones that I beat up, and once again there in Miami they all are race ready skis, and no one is in stock form, I even race the owner of a performance shop for Yamaha there in Miami and he was on his new and modified fzr and ttr12 got on my ski and kill him, I think that I made a lot's of enemies down there... All thanks to SuperMac...lol ....they didn't believe me when I told them that it was just Mac's computer as my mayor mod, and the other things were the wedge and intake.. The F15X and supermack are here to change the way that people think about Honda racing....

Thanks mac, when i got my first set of mods from you i wasn't so sure, but the first time i used them i was hooked, now even before my new (used) ski arrives i ordered your mods, they kick ass man

Went out and tested the new Intercooler today. All i can say is WOW!! Heatsoak is no longer a issue!! You can adjust your boost levels to suit your yours and your ski's needs or wants. With the MB module and IC, Solas 17/29 prop and some arm strength I can hold ski WOT all day with vertually NO heatsoak!!! Awesome job Mac!! Keep the speed coming!!! Rating:  [5 of 5 Stars]

Seriously thought hard about the "other" 4 grand upgrade. Boy am I glad I went with Macsboost. The module pluged in, in seconds. Midrange hit, launch, top end all greatly improved all day long in 85 degree heat (water 72 degrees). Today was the first time I am actually sore after riding my F 12x. I couldn't get a good topend reading as there was so much chop on my lake today (sunday) but I have ridden in these conditions many times before like this, but I have never launched off of wakes and got the airtime like I did with Macs module! Honestly, never thought I could get airborn with a threeseater on my lake because the chop is so mild as we don't really have any big boats on our lake. Not anymore. In fact, if it had anymore power, for me it'd be too much. As it is, I need to modify my intake grate now to reduce the cavitation which has increased with the newfound power.

I was really impressed with the ease of installation. If you own a Aquatrax you need to get one! Rating:  [5 of 5 Stars]

Put in module last week so simple a cave man could do it. Seriously took all of 5 mins it takes longer to get the seat off then plug the module in! The improved acceleration is well worth it.  Dropped in stage ii kit thursday-must admit had the shop do that part but they also said it was very simple. Anyway WOW have a 2006 F12x in colder water have been able to get it to 64mph on a freak top end jump now it rides at 65mph and stays there in much warmer water---before intercooler got it to 62 mph in warm water for a moment and before the mod it mostly stayed at 60 in warm water. A big jump in aggressiveness as well. Actually had one of my friends ride it and he gave it back after about 5 mins and said it scared him and he wanted to ride my 2006 f12 -non turbo. Great job !

Here I am, the lucky sole with MacsBoost Module #1 ... And it arrived just in time for the weekend. Can you say Sa-WEET! :) I got a full day in yesterday of fun and testing with this thing and I just can't get the grin to go away! :) 

First thing... Installing it. Oh My Gawd, can it be any easier?? Put a piece of velcro down on the air intake runner, pop off the plug to the sensor, and plug in the three clearly labeled wires on either side and your done!! Put your lanyard on and watch for that pretty blue led to light. No problemo! I was installing and removing it all day long to swap between the F and the R. There's no need to beach them, just pull the seat and one minute later it's done. 

And, what does it get you?? Arm wrenching acceleration! I've long been used to the way our turbo craft accelerate. It no longer really excites me to pin the throttle from a standstill just because I do it all day long during my races. But, with this module on, my heart skips a beat with how much more pull I get from this thing! Not to mention, the engine has a little more growl to it. :)

To put it in more tangible terms... Runs without the module I was running about 6150 to 6200 rpms, and with the module I'm running 6380 to 6400 rpms. Doing Side by side runs between my R-12X and F-12X, both without the module, they are dead even. (Sponsons, grate, prop pitch all account for my R going slower) But with the module, the R pulls away from the F from the start and keeps walking away. No contest! I gained a solid MPH from it. GPS confirmed. Before I was getting 57.9 and After I saw 58.9. 

BTW, this was a 100 degree day with at least 75 degree water temp. 

The one important thing to note... Good fuel is a MUST! Especially on a hot day like yesterday. The stock ECU's safeguards are in full force, and if it detects any knock what so ever from old or lower octane fuel, it can and DOES cut you back to protect your engine. I hit it a few times on the F, who's fuel isn't as fresh as the R's. It just cuts you back a few hundred RPM's until you pull the lanyard and let the display shutdown. Then you're all good again. 

Overall All I've got to say is... Way to go MAC! You've got a winner product here. Simple, easy, and very effective! I'm sold, and will be getting another for the F-12X. 

Get one or get passed. :)

P.S. It'll be ran in RACE conditions next weekend. Expect a report afterwards.

Ok... It's another hot one. 104 in Modesto. And this time I'm out on the delta. On my way out, I stopped by monkey's which carries VP 110 fuel. Put 5 gallons into the R to bring the meter up to full, but had some room left in tank. Went out to Mossdale's Landing and put in. I headed all the way down to the main channel and then down past Windmill Cove and Lost Isle, finally ending up at Herman & Hellen's Marina. After munching on a drumstick, I turned around and came strait back... only distractraction was a quick tow of a sunken sea-doo over to their ramp. :) .... Fuel alarm went off a few miles from the home dock, so it was a full tank run. 

And, it ran PERFECT! Going down river (river moves about 1.3mph) I hit a max of 62.5 at 6400 rpm's... And, it stayed that way for a while then dropped down to about 6300 rpm's for the rest of that and every other extended WOT run. It'll go all day right there... and I know this because most of my trip was run at WOT. 

That's it. The gas solved it! The computer never detected any knocks and never backed me off. Yay!!! Thanks, Mac! I love this thing. Just for kicks, I pulled it out at the last 5mph zone just about a mile or two from the dock. And, without a doubt, I lost 200 rpm's just like that. Even on a Hot, heat soaked engine, it still works. Where I was getting 6020 rpm's without, I had just previously been getting 6250-6300 with the MacsBoost. It just works! 

Sa-Weet! Can't wait untill Friday to put a whoopin' on all of those Yamaha's, Kawi's and Sea-Doo's. :)

I just installed my module on my F12X, and took it for a spin. 
I couldn't believe it. 

WOW....Feels like the Honda is on 'roids !!! :)

Now that's what i'm talkin' about...performance you could actually feel. 
Mac has designed a great product you guys. It makes the Aquatrax come alive. I mean as soon as you squeeze the throttle, you hit 60 like in 2 secs. Instant throttle response. I raced another F12X, and blew it away. 

Excellent product. Easy installation ( 1 min.). Amazing performance.!!! 
What more could someone ask for ? :)

Thanks Mac. 
You deserve the "Best Mod of the Year Award", no doubt about that.

I took my ski out yesterday and raced my buddy on his RXT, before MACSBOOST he would walk away after 50 mph. Now he isn't going anywhere, we raced back and forth across the river same results everytime, he still could pull about half a boat length on the hole shot, but after that we stayed side by side. The only way one would pull on the other is if you got crossed up on the chop. Mac again Great product.

BILLY-R12X

Well rather than just post it's awesome and go buy one, I'll tell my experience after a full weekend of riding. 

So first, the module installs literally in 5 minutes. I'd like to see some weather tight connectors instead of pins, but the wiring is waterproofed, so I do not see a long term problem, should be just fine. 

Conditions: I was at the Colorado river in Blythe CA, on Saturday it was ~ 105, and the water was ~90-93 degrees. As I can only get 91 octane here in CA, I put in 5 gallons of 103 octane unleaded and then topped off with 91. I think this gives me around 94ish octane. 

I had my daughter as a passenger all weekend, and my boat is an 02 F-12X with a custom pitched Solas impeller, and 3 intake grate bars removed. 

So on the first ride, I rode kinda easy for 10 minutes or so to warm it up, then hit it from around 20 mph. Much improved midrange to top end charge, 30-50 seems to take around 1 second. You can certainly feel the extra 2+ lbs of boost, the arm stretch you normally get seems to be almost 2x. 
Out of the hole, my boat with stock boost has very little cavitation, but it now leaps out of the water much harder causing a little cavitation. The boat is definately quicker out of the hole now. 

So now it was GPS time (Garmin Rino 120), and my boat stock on this same water earlier this year did 59.8 mph. The water was also MUCH cooler when it did 59.8. 

My best peak one way run was 62.5, but the averages were around 61.7 both ways. 

Realistically, I could care less if it went the same top speed, MACSBOOST is about the midrange for me. The midrange is killer now. At any time off boost, when I hit it I get about 6430 rpm's for a few seconds, then it settles to around 6360-6400 for as long as you keep it pinned. 

Sunday: I had to add over 3/4 of a tank of gas, and it was 91 octane. Sunday is hotter and more humid. Probably 110+ degrees. So now I figure I have around 91.x octane. 

I take off and it feels exactly the same, except if I keep it pinned for more than 20-30 seconds, the boat reduces boost and I get around 5800-5900 rpms. You must stop and remove the lanyard, then wait for the display to go out, then start back up and your full speed again. I got to the point where I could blast and then know when to let off for a while to keep from having the ECM reduce boost. 

Fatalities: 15F Kawasaki. :) One point I had 3 up (equal to about 2 adults), and had a 15F ride up to the side of me (he was just himself), he looked over and we hit it at about 30 mph. I didn't blow by him by much, but he did get to see my tow ring. The midrange hit pushed me a boat or 2 in front, then my top speed was a mph or so higher, and I kept pulling away from him. There were a ton of Turbo Hondas on the river, and he picked the wrong one to mess with. 

My observations: This kit gives you about 80% power of a properly setup manual boost controller kit. MACSBOOST retains the ECM's ability to reduce boost after the intercooler is heat soaked, the manual boost controller does not. This is easy to install, lift the seat only once, never ever hear an overboost alarm, no tweaking, no riding w/o your seat trying to look at gauges. Works the same from one day to the next which is sometimes an issue with manual boost controllers. 

I suspect that cooler temperatures, both air and water will allow 91 octane to work properly at max power, but I haven't got a chance to try this yet. Sundays gas was really close to working, but was a point or 2 off. Ocean is next weekend, and it's 70 degree water temps, and 80 air. The stock intercooler does totally suck though. I think there are good gains to be had there with the added boost. 


Conclusion: MACSBOOST will not allow you to hurt your motor by either too much boost, or too high temperatures. As the module uses 5 volts that the ECM was sending to the sensor to power itself (my guess), there is nothing electrical that the module could possibly do that could hurt the ECM other than dead shorting. I suspect the ECM is protected against that anyway, as sensors can short. So I see no electrical risk to the stock electronics, there was flawless operation over many gallons of gas over the weekend. 

I think MAC hit a homerun with MACSBOOST. 

This gives a great boost to the stock ski, and keeps all the stock protection in place. Bada$$ midrange hit, makes you want to slow back down so you can feel it over and over again. It's not the kind of add on you have to try and see if it made a difference, you'll feel it! Plug in and forget, no hassle. 

So is it a keeper? 

Well, the sticker is going on the boat tomorrow (after I wash it). 

Thx MAC!

Went out today in Mission Bay, San Diego CA. Was a total zoo, mega chop. Temp was a nice 80, and the water was mid 70's, a nice contrast to last weekends furnace weather. Ran 91 octane, had a can of octane boost standing by if needed. Was not needed! I ran all day long, never had a single boost reduction due to heat like last weekend, and did not need the octane boost either. 

I had posted a while back that I have a friend with the 185 hp Seadoo (G-Tec or something like that). He would pull me outta the hole, and keep pulling until we let up. He, he, well today the story is different. I can get him out of the hole pretty good (Leaning over the handlebars on the holeshot like last time because the water was so rough) and then I just keep pulling him forever. I was totally surprised, and so was he. We did it several times with the same results. I can easily beat the other stock Hondas in our group too. The only one I can't beat in our group is a brand new RXT, but it's pretty close. Just another pound or so of boost and it'd be even. 

I now regularly get over 6400 on the holeshot, and I get close to 6400 when WOT, forever! It is definatley faster than it was in the hot temps by far. I was caught off guard a few times when getting into the throttle, the boost took me by surprise. 

This kicks #$@%!

I recieved mine on friday and installed it in less than five mintues. Great and easy directions mac. This aftermarket part is unbelievable. The hole shot, midrange and top end is like night and day. This ski is a little scary now. My rpms before mac used to read around 6,150. Now its about 6,420. The weather was very hot when tested, 95 degrees and humid and the water was around 83 degrees. I did not notice any real rpm drops at full throttle. I have been using 93 octane for three years now. The investment is well worth it. It about time someone made and aftermarket product for such a great ski.
Rayrider

These things are exactly as you advertise. Unfortunately, none of my fellow Honda riders came out and played with me this weekend.
6,300-6,350 rpms was steady throughout the day on Sat. No problems.
Noticable midrange hit. Good job Mac. Simple, easy install. 20+ HP increase in a 2 min. install.

I just took out my F12X with the MACSBOOST chip, performance with a chip? Damn right!!!! along with the solas prop ski is better than I thought it would be. Thanks Mac I'm now waiting for the IC

I went to the lake this morning to test out my macsboost and armed myself with my friends gps. Weather was calm and the lake was glass. I first ran stock (with modified ride plate) to get a reading. Average gps speed was 61.8 mph. I then put macsboost in. It makes the R cavitate worse than the F. I rode for a while before doing any testing. The ski was definatly faster and really walked the f badly. I was amazed. There were a couple of other hondas out there (both r-12x), so I raced them. There was no contest I walked them almost as bad as the f. So I finally decide to do a gps on my now heat soaked ski. After several runs in every direction my average speed was 64.1 miles an hour btw all runs were with 93 octane. This module combined with macs exceptional customer service made this a very worth while purchase. I am sorry I ever doubhted. I WAS WRONG!!! I only purchased the module, but I must tell anyone who is going to purchase this you should really same some money and buy the impeller at the same time. You will regret it if you don't.

My Honda was running good Saturday..... Ok all I did not think my bike was going to run 63.6 MPH on the GPS with the Macsboost chip only but it did, water was 87 and it was pulling hard with me it went 62.9 MPH and with a 180 pound rider it did 63.6 MPH I was shocked, can't wait to install the I.C. and the 17/29.prop..... I think 67 MPH is not out of the question.....
