We got the Fiat 124 project out for Dyno time.... with Shiv's OFT (Open Flash Tablet) Reflash! First, a word about Dynos. A dyno is merely a tool for before/after testing. Difficult to impossible to compare peak numbers on one brand of dyno to another brand of dyno. Moreover we know there are some vendors out there telling you that they can get you over 40 hp with some plug and play piggyback or reflash, and perhaps there is even a special Unicorn Farts brand of dyno that you will likely never find that supports their results....but our bet is that customers will never be able to repeat those results. We want to give you results you can repeat on any four wheel dyno.
We bought the top brands of piggyback that were available and tested them on two wheel dyno....AND four wheel dyno. The Madness shop makes no claims for particular numbers that we have seen yet won the contest of piggybacks in our testing. Lowest BLUE line in graph below was stock. Middle line was best for our three piece exhaust system of Crossover Pipe, Midpipe, Muffler Delete. Highest line with piggyback and prototype highflow cat. Tried the Madness piggyback in all modes and removed from the car, then put back on car, as expected the 'SPORT PLUS' gets the best result and that result is another 10+HP.
Now for dyno of the reflash. Different dyno....much more conservative dyno! Lowest line in dyno below is the winning combo from above, the most successful of the piggybacks that we could buy, from Madness, again in Sport Mode with full exhaust system. We did all the modes again on this four wheel Mustang dyno and repeated the same results we got on the two wheel dyno, which is to say the Sport+ mode got us best results and those results were consist 10+ hp gains over stock calibration...and then we left just that best result on the screen as our new 'baseline' from which to test the reflash against the best of the piggybacks.
So, again the low line below is not stock calibration, that low line is best with full exhaust system and Madness Piggyback. This particular four wheel dyno is a Mustang dyno, well known in the industry as the 'Heart Breaker' because it reads lower than just about every other dyno. We really don't care if it reads low because remember what we are looking for is the delta, the difference between the reflash over the best results with piggybacks that we tested. Given that this is the MOST CONSERVATIVE dyno, we are confident that customers will get at least as good as our results and likely better on any other brand of four wheel dyno. Results for reflash are peak HP up another 9hp, torque up another 10 points (more delta if you look off the peaks). Though our testing of EC's piggyback failed to confirm their claimed gains, their claims that a four wheel dyno gives much more consistency did get some support in our testing and only on the four wheel dynos did the dash not light up with warning lights, etc.
Note operator above had not changed the gear calc to finalize the result with correct crossing of torque and hp curves, doesn't change results... but final below with correct crossing points.
Finally, Shiv as the Tuner of OFT is not local to us, so he visited a DIFFERENT LOCATION with another four wheel Mustang Dyno and he ran a test of his reflash and he posted the results below. If you are keeping track of the math recall that we got about 10 hp for best piggyback real world at the wheels on our local dyno over stock factory Fiat calibration, and we repeated that same gain on Mustang Four wheel dyno, and then used that as baseline to test the reflash on the four wheel dyno and got about another 10 or so gain for a total gain of about 20 hp over stock calibration on a Fiat 124 that already has gains from full exhaust system. So, for consistency looking for Shiv to gain roughly 20hp over stock calibration...and that's what he got. What I like about results below is how well it backs up our gains we got for Shiv's reflash on the other Mustang Dyno noted above.
