Picked up about 45 hp and 65 ft lbs of torque

[commonsense]

2013 Abarth. Stock except for K and N Cold Air Kit, Magnaflow exhaust and Maxpower piggyback ecu. Still has stock catalyst. Dynojet dyno. 173 hp and 200 ft lbs of torque at the wheels. Should be making about 205 hp and 235 ft lbs at the crank. This is figuring the usual 15% losses from wheels to crank (the tuner says this is close). Thrilled with the little monster. It goes like stink. It's making max torque at only around 3300 rpm. It's too 'fat' (rich) on top. I think there's another 10 or 20 hp, at least, if it wasn't so rich. But, overall, very satisfied. By the way, there was no way to feed the side mounted intercoolers air, during the run. I'm sure on the highway it will make even more power.

Anyway, the car is FAST. On the way home, I raced a guy in a built BRZ and he was shocked I was pulling him in 4th gear. After reading the dyno chart, I'm short shifting at 5500 to keep it in the meat of the power band.

My dyno results match very closely to what 500 Madness shows on the dyno plots (for the Max Power module) on their site. So far, I have been nothing but pleased with them and their products.

Followup. Eric, at 500 Madness, told me that the tunes go very rich at 5000 RPM to protect the motor. They also roll back boost at 5500 RPM. You can see both dips on the dyno chart. So, there's more power there, with further tuning, but I'm content with it the way it is. Have you ever seen a dyno chart that pretty much starts at its highest and then tapers with RPM? I haven't. On the site, they say "we do not chase top horsepower numbers that look good on a dyno, but rarely provide smooth and useable power delivery in the normal range that you would use a car. While the gains we provide with this product are fantastic, they are also safe" That's what I got. Highly recommended. abarthdyno.jpg

I love the Maxpower. Have you had any issues at all with it detuning itself and having to reset the ECU? I have a hard time telling for sure but it seems like sometimes it doesn't feel as powerful.

I experince that in very hot days with low humidity. However after installing a after market FMIC corsa forza - car feels stronger even on hot days.

Overall I am happy with my MAXPOWER its been on my car for over a year now, no prob. And if I need any help or have a problem with my car 500Madness crew is always there to help me out .

I did initially get the bluetooth version and the connection was not reliable. So, I returned it and they sent the permanently on Maxpower--and refunded the difference. I've had no problems so far. It feels strong all the time. I think that with the 'Sport' button off, it's at least as strong as it was 'stock' with the sport button on. And this is a great setting as I like the more relaxed steering, and 'lazy' throttle response. If I'm driving fast, or see another car I'd like to 'play' with, I turn the 'sport' button on.

You will feel less power when the inlet air temps are higher. I have an 'Ultragauge' which gives me information on exact water temp, air inlet temp, timing advance, boost, and air/fuel ratio (in Lambda). On a really hot day, air inlet temps can be over 130 degrees. This will mean less power. I'd like to get another hood, and add an air scoop, to cool the under hood temps. Anyone know where I can get a white hood for a reasonable price?

[majora96]

The Madness thermal blanket might be a good option for cooling the under hood temps. I haven't purchased it yet though.

eBay have some primed hoods for around 300 bucks or
u can try a local junk yard...

I have added the Neu-F torque arm insert and it's a nice improvement. Aside for a little bit of vibration, just off idle, you can't tell it's there. But the drivetrain seems tighter. Nice upgrade for $40. Maxpower is still running perfectly. Best thing I did to the car.

I'm very interested to see how everyone is running with the MaxPower ECU, I have it on my dart currently along side a TMC Powergate tune, MaxFire coils, MPX underdrive pulley, intake, tubes, yadda yadda. I did a big turbo swap and I'm running 259 to the front wheels. Frankly, it's more than my transmission wants to handle so I'm picking up and abarth tomorrow and taking everything off the dart and transplanting it to the Abarth.

Can’t wait to see how your new Abarth turns out...Sounds like you are going to have the mods right from the get go...Too bad they never made a new GLH Dart!

This confirms how I feel about my Maxpower. Hits really hard down low, but zero point to holding gears past 5500 other than to make noise.

Throw the bypass plug in. Should be a noticeable difference.

OT: Does anyone know the preferred way to reset the ECU while using Maxpower? I think the ECU learns over the first 80-100 miles or something like that. Most sources say, go on a fun drive and drive the snot out of it. If you doddle around on your daily commute or around town the ECU "learns" to be lazy. Can anyone fact check any of that nonsense?! =P

Welcome to the forum Redline5th. Post some pics of your Dart if you have em handy, sounds like an awesome build.

Is the C510 trans that much stronger than the one in the Dart?

I looked again last night, this is something I did a lot of research on the last time my C510 melted. Based on the pure specs from FPT Powertrain Technology (who make both boxes) the C635 can handle about 30% more input torque than the C510. So I assume the reason Fiat put the GM Manufactured M32 in the Assetto Corse cars is purely for physical size, although both boxes are about 20lbs heavier than the C510. Although that's a different conclusion than I came to a couple of years ago (also from FPT data).

There they both are. The dart keeps the big turbo, and the TMC tune... and injectors... and FMIC. I'm hoping to keep that somewhere around 200-215 hp after I pull the handfull of stuff off that will easily swap. I don't want to pull the turbo, becuase I'd have to revert to stock tuning. I don't have have my OE map anymore so that would be a huge pain in the ass. I went with a big wheel/stock housing on that and I'd like to go with something different in the Abarth anyway. Maybe td04... not sure yet. The transmission itself is robust enough to hold another 30-40 hp and torque, but the clutch is not. Not even a little bit. It already like life quite a bit better with just the MaxPOwer off. Sorry I don't have quality engine bay pictures as of now... car season starts soon, i'll be snapping more shorty.
