    Yes a small LED flashes when I press a button, but that's not the same as getting a visual confirmation.

    I'm not unhappy with the performance at all - just wondering if I'm leaving something on the table. I'm also just a bit confused as to why there should be a 35 HP difference
    between my dyno HP number and the 500 Madness numbers posted some time ago for a MM equipped similar vehicle. I as actually expecting something near 200 whp, but maybe that was unrealistic...
    Are you referring to this thread:
    http://500madness.com/500madness/for...=3687#post3687

    Exact Quotes from Thread:
    The first run was done to establish a baseline. We ran a stock ABARTH with no modifications on 91 octaine gas. The dyno showed 155 HP.

    The second run was done with the TMC Box set at the #8 setting. No other mods were on the car besides the TMC Box. Dyno Sheet below.

    TMC Box (no other mods) on setting #8 = 187.6 HP

    We tried taking the TMC box up another notch, but no further gains were attained.

    Next one up was the Magneti Marelli Module. We set the MM Module at 77% (the default setting and the same setting that was used on the Venom Concept ABARTH).

    The ABARTH with the Magneti Marelli Module hit 196.5 Horsepower. No other mods were on this car besides the module.

    Read Further in... they have someone explain how their numbers came from a Dynapack.

    I'm still not convinced on the bang for the buck factor of the piggy back modules.

    And yes, Henderson is a great tuner and I have confidence in their dyno skills.

    Nice to see another central Texan on the boards

    You bet dude.

    BTW, they probably saved your run, give him a call and see if you can't a copy of the A/F

    As far as dyno numbers are concerned, unless one is trying to ascertain a transfer or frictional power loss somewhere, gross numbers from a chassis dyno are pretty useless. What matters is what gets put to the ground.
    Nothing, as long as you can be consistent, is as good as track time. It's like losing weight, you're really not concerned with the scale, but the measuring tape.
    Retroguy, the tq is a decent increase from factory claims. The HP numbers? Who knows. If you dyno the car again get them to give you an rpm, O2, ect, iat, cht, map, and egt readout. Injector pulsewidth, FP and timing would be nice if they even have that capability. It'll go a long way toward diagnosing the 'lack' of increase. Of course, this is providing you can afford it, but then this is getting further away from 'just a dyno run' too. So it may be overkill for your needs.

    - Honstly dude, I would stay away from the people that wrote that thread... In the past I wanted to believe their items would make my car as good as they advertised ... then I found people that are real Fiat enthusiasts with honesty and a brain that showed me the way.

    - The MM unit, has had nothing but terrible review all accross the board. You see them in the classified section all the time. The only good thing about them is you can show up at the Studio with it installed since its a MOPAR accessorie...

    - I wouldnt waste my money on another dyno run with that set up.
    Return the unit if possible.
    I would go TMC or R/R($100more). I cant guarantee better results ... but it has been a popular choice.

    - Also the MM unit has the 3 settings correct? well that doesnt mean you are set at 50%/75%/100%. The mm unit can be programed.. the the 3 levels COULD be set for 55%/56%/57% if you really wanted to...

    so you are kind of in the blind right there my friend depending on what the controller came programmed with...

    the ecm though in general, there is a noticable difference in my opinion. is it worth the money? well... I wouldnt want to give my R/R ECM away.

    we bought a cars that are fairly inexpensive. $500 for the boost it gives, is fairly cheap.

    Two runs were made. The second run was made within just a few minutes of the first, and was lower because of something described as "heat soak".
    I was surprised to see that although the max torque was up from published Fiat specifications (196.6), the wheel HP was only coming in at 162.8 HP.
    The technician who ran the testing said it felt to him like something was holding back the car.
    ....
    Does the car pull consistently on the street? 30 LbFt of torque in the midrange is hugely noticeable....about the difference between Sport and normal modes. That's my hunch between pulls; that Sport was pressed Off for the 2nd run. There looks to be a boost reduction across the RPM range.

    Thanks sfhpawel and Ryephile.

    Concerning the reputation of the vendor that posted, I personally have had nothing but positive experiences with them, so I'd like to keep an open mind on this subject.
    I definitely wanted a piggyback arrangement and not an ECU reflash because it leaves the ECU engine protection safeguards intact, and presumably the worst damage I can do would be to throw a few codes or trip a limp-home. And even though Magneti Marelli is owned (partially) by FIAT, the ECU piggyback is not yet a MOPAR product, but
    I find that the studio mechanics and managers don't seem to take an extreme hard line on Warranty - at least while everything seems to be OK with the vehicle

    There's no question that the with the MM ECU piggyback and the Power Petal the car's driving personality is changed significantly, and in my opinion for the better.
    I like to drive it in MM setting 2 in non-sport mode. Steering seems a little more comfortably relaxing, yet it will still hit boost plenty fast when I stomp on it.

    You are correct that the MM boost settings are programmed into the ECU, and supposedly setting 2 is 77%. 77% of what, I have no earthly idea, but that number is supposed to be just under the threshold of throwing CELs. I have not thrown a CEL once since the install a month ago. Bottom line is that overall I'm happy with the improvement. I'm sure I would have also been happy with a RR or TMC ECU as well - many people are. I see no compelling need to swap it out at this point.

    Ryephile, you know that's a really astute observation. I know that the technician shut the car down for 5 minutes before the second run, and maybe he just plain forgot to press the sport button. In any case, I do not notice any difference between pulls on the street. Seems the same to me, so that's why I scratched my head when he talked about heat soak. And you are right, torque is noticeably improved according to my butt dyno.

    Does anyone think that adding a blow off valve would make any significant difference to these curves?

    Thanks all

    Doug

    Really.... I'd love to see the MOPAR Performance Catalog that list the Magneti Marelli Piggyback as a MOPAR Accessory for the DART and ABARTH.
