Today we tried modifying the AMXY memcal to gain back some power in comparison to the AKFL memcal. We had partially received a reverse-engineered $54 definition file (for the AKFL) where we were able to copy the F1 Main Spark advance table, the VE (Fuel map) and F60 Open loop a/f vs MAP in place of the AMXY equivalent tables. It seemed the injector flow constant was different between memcals which we thought was strange. We tried replacing the AMXY injector flow constant with the AKFL equivalent but it didnt make much of a difference. If anything it seemed worse. Our thoughts were maybe the slightly more aggressive spark advance values, etc.. might help restore the power but this was to no avail.

While the original AMXY memcal made the car run like a pig, we were able to make the car run significally better; albeit still with a lack of power but atleast the car didnt feel like it was hunting to change the fuel amounts. With the WinALDL diagnostics running on the laptop you can tell if the car is adding or subtracting fuel by looking at the BLM and INT values. These values should be as close to 128 as possible at all times/load points. We burnt several memcals with the WinALDL diagnostics running to monitor the BLMs and we did get the AMXY modified enough to maintain near perfect BLMs, but the question is still what else we need to look for to return us that low-mid range torque and general extra pull you can feel with the AKFL. Its such a difference that you can feel on the road! Hopefully we will find what we are looking for soon enough.
