Hoping I could get some help, tuning an FG in a speedway car, loom was made by the customer, no speed input, and I hit a rev limit of 6500.
RPM cutoff both maxed to 10,000rpm, neutral and drive cutoff tables maxed to 8000rpm. Launch and ETC both maxed. Torque ratio fuel and spark set to 0.0 and 1.0 respectably.
Torque module switch is still enabled, if I disable it is torque limtied somehow, throttle is really doey and it won't rev.
Trans-General-Automatic is set to enable, if I disable the engine is rev limited to 3500rpm. Have also tryed most load switches and infered neuatral settings but unsure if there is a combination of the above that I havn't got right, or if it is because there is no speed input.
Engine has been built, CNC ported head, cams with 250something@50thou lift, higher compression ect, hense why I would like to be able to raise the limiter as power is still climbing.
If anyone has had any experience with this it would be greatly appreciated. If all else fails I will just send the ECU to someone who can bench flash it with SCT
is it a 5spd, manual or auto base tune?
you can keep auto enabled, for no limp you basically need to raise the limp/FMEM trans fail limits
to run it as manual with the auto switch disabled the ecu needs to see the output side of a reverse light switch - i assume it looks for like .2v that bleeds past the switch. without it the ecu runs locked in reverse torque maps, so low rev limit and low commanded torque.
theres another thread that has all the info about what changes need to be made, cant remember the title tho. have a search for fg limp mode.
