Ive got a question for anyone who knows how to burn chips. I would like to know how long my cammed l98's injectors should be staying on at idle. I've got the tpis zz-409 cam (226 degrees intake, 226 degrees exhaust at .050"). i have an afr guage and i run the diacom software. the car seems to run rich everywhere and when idling it seems to run rich as hell. looking at the diacom the injectors are staying on about 1.4-1.7 m/s, and the afr guage and readout on the computer both indicate the car is staying rich. also throughout the driving range the integrator and blm both stay at 80-90 and 108 respectively. i have a tpis level 4 chip, but it seems that the computer still thinks the stock cam is in there. if anybody can point me in the right direction, i would appreciate it.

i just did a car with a tpis chip. get your money back. buy the equipment and diy the chip. if not figure out who's in you area and go see them for a custom burn.
