Is MP215 the way to go?

    My FIST just arrived yesterday and I am picking up today. I already have the MP 215 kit in my garage waiting to get installed by the dealer. I am actually happy that the torque limiting is still present with the MP 215 as spinning the wheels in the lower gears seems pointless and would affect low speed handling

    I hate that limiter, I and not the car, should be in control.

    The reason that limiter is most likely in there for the 1st and 2nd gear is for two reasons, first to prevent excessive wheel spin and second & more importantly to limit the amount of torque being applied to 1st and 2nd gear. Again the reason why Ford is approving MP215 as warranty approved is because they don't want to shorten the life of the transmission by wrecking 1st and 2nd gears because they are probably only designed to take only so much torque.

    I have seen this in other cars where guys add a turbo to a NA engine and experience a short time later a failure of 2nd gear in the the tranmission due to the change in gear ration between 1st and 2nd gear and all that torque being applied to 2nd gear when it wasn't designed for that level of torque.

    So basically you can say, that the ST´s transmission isn't up for the job - even standard wise.

    I'm saying there and reasons why manufacturers generally try to limit torque being applied to their gears in the transmission so that the transmission as a whole has long life expectancy. The transmission is designed for the job of the stock car with no mods, I don't think 1st and 2nd gear are designed for the full amount of torque available and at the same time have a long life expectancy.

    Shouldn't be an issue while you're breaking it in. Be nice to it! lol

    I wanted to piggyback on this thread with my issue. I'm wondering if I do have an issue. I'm a total newbie to tuning but I've had my mp215 for a while now. Here is a screen shot of my mtune can someone tell me a) what I'm looking at and b) do I have a boost issue. All I'm seeing is -0.80 to 1.5 is this normal? Or should I be looking at different gauges

    Yes you have a boost gauge, the one that says "Boost Pressure" and the units are in metric as Bar. If you want to see the numbers that everyone talks about 22psi of boost you'll need to change your units one of the menus. You will want to pick the one that says imperial/metric I think. which will give you psi and deg C for your ACT air charge temperature.

    Ahh see that would help. Thank you. I'll have to fiddle with the settings some more. Wish this thing came with a manual...

    You can download the manual from Cobb:
    https://cobb.app.box.com/ap3-for-usermanual

    It's not exactly the same as the mTune but will help you with accessing the different menus. Cobb's AP3 has a lot more features than the mTune. Have a quick and you'll be a pro oh and make sure you keep your firmware on the mTune up to date. Think there was one before Christmas that adds support for 2015 FiST and fixes glitch to reconnect with car after car is restarted. Before had to turn off and turn back on.

    I use to have a Kawasaki ZX-14. Slightly modded, 170 rear wheel HP and 115 ft. lbs of torque. Kawasaki also limited power in the first 3 gears. Of course the internet expects said this was total garbage and determined if you removed the secondary throttle flys (controlled by the computer), you could have full power in all gears all the time. So I decided to do this mod. Now this was ok in a straight line. You could keep the front wheel off the ground until you hit fifth gear. What was not as good was when you were in corners in the lower gears if you hit just a little too much power the rear tire would break loose on dry pavment or the bike would try to wheelie or do both at the same time.
    I guess if I had Moto GP riding skills, this would be no big deal, but pulling a wheelie or smoking the tire when the bike is laid over in a corner at 100 mph is little disconcerting for most.
    I put the bike back to stock (put flys back in, but left on aftermarket exhaust and power commander) and was much happier and still alive to talk about it.
    Bottom line, don't assume your engineering skills or the aftermarket exceeds the manufacturers engineering skills.
    If I wanted a much faster car than the FIST, then I would have bought one. I am confident the MP 215 kit will give me what I need and not kill the long term reliability of the car.

    Bingo, we have a correct answer! Use to have a turbo Miata with the Flying Miata set up. Great after market turbo set up, but had a rear differential failure eventually and synchro's went prematurely in the transmission. Turbo more than doubled stock HP and torque. I drove it moderately hard but did not auto cross, but as well built a car as it was, was not designed for the power increase I gave it

    I was big in the Suzuki Swift GTi scene for a number of years, thus my name, anyways saws guys take the stock 1.3l dohc engine put a turbo on it with 200hp at the front wheels and then wonder why they were killing 2nd gear?

    I had an '84 Colt turbo that also fried the tranny. I didn't even beat on it (though I'm told an ex-friend of mine did). The stock tranny just wasn't up to the extra torque of the turbo.

    The stock car made around 70 hp/tq, The turbo made around 103/115. That was enough to break that tiny 2-range tranny.

    Best tune for strong torque at the top end ?

    Randy's custom tunes for your specific car. 91 or 93? E gas? Intercooler? Downpipe? It all matters.

    95 octane at worst(EU car) and no hardware mods...

    Hmmm I think for a EU car you will need to seek a MAF tune such as Revo or Bluefin. I know nothing of either or any others for the EU cars. As I am Randy Tuned and happy :) sorry to be of no real help for your specific car

    What is the difference between COBB and Revo? (output wise)

    Thanks for your reply and Randy sounds like a nice guy :)

    I am not exact on the output but I would think they are close I would research them and the other tuners that make tunes for the MAF car ..
    Randy is a super great guy and a well versed tuner..
