Need Fuel Map For Lt8 Please
 
INSTALLED ON S4 WITH STOCK 550CC INJECTORS, I AM NOT ABLE TO TUNE IT TO DRIVE IT AROUND, I CAN ONLY GET IT TO STARTUP AND IDLE , BUT WONT ACCELERATE WELL, IT SOUNDS UNEVEN, WHEN YOU DRIVE FOWARD IT CUTS OFF AROUND 2500 RPM, IT STARTS MISFIRING, DOES ANYONE HAVE A FUEL MAP THEY CAN SHARE SO I CAN HAVE A STARTING POINT. THE AIRFUEL RATIO STAYS AROUND 15.00 BUT IF LOWERED THE MS ON THE INJECTORS TI GOES AS HIGH AS 18.00 BUT IF RAISED THE MS ON THE INJECTORS IT DOESNT DROP BELOW 14.7 ON A/F

IT IDLES
20"HG-1.90ms 15"HG 1.67MS
LOAD MAP IS BASIC FROM THE FACTORY, BUT I HAVE TRIED LOWER AND HIGHER NUMBERS WITH NO SUCCESS.
ANY FEED BACK WOULD BE HELPFUL, I HAVE CHECKED THAT BOTH PRIMARIES FIRE AND THAT THE 4 COILS FIRE AS WELL, ONE THING THE TRAIL PLUGS ALWAYS COME OUT WET , AND THE LEADING DRY. IF I LOWER THE IDLE FIGURES TO LEAN IT OUT, IT RUNS WORST

something is not rite with your setup the stock map works perfectly with stock injectors,

check you tps is set correctly and the timing is set right

sounds like the staging of the sec injectors , ihad similar problem and found that the sec injectors where frozen .
just a hint.

thank you for feedback, i have calibrated the tps, like the manual asks, i have to set at 00 when pedal is closed and then when i step on it, it goes up to 99, that is what the manual says, the timing i have check as well. but the map numbers from the factory has worked for you guys well. i mean the map from micro tech?

check your rpmlim/rpmcut. See what those are set at. And also check the wiring for your injectors.
