What PID to scan commanded afr & injector duty cycle for e78 ?
What PID to scan commanded afr & injector duty cycle for e78 ?
EFILive Tuner
Start by trying IBPW1/2 and INJDC1/2... those may or may not work for E78.
I Tryed both
its not working they are giving higher values more than 100% even in e38 i havr the same problem
And what about commanded afr ?

Joe i tried those also they are not valid in E38
I need to log the duty cycle urgently because I'm going to tune FI car

For E38 there is a set of pids named E38.xxxx (same with E67), I'll have to look at which ones are the correct ones...
in the meantime, can you find which injector pulsewidth pid gives sane values (e.g. 2ms at idle and under 20ms at 6000 rpm).
The pids for pulse width are GM.INJPWb1 and GM.INJPWB2

Copy attached calc_pids.txt to folder My Documents\EFILive\V7.5\User Configuration
Then select the following pids:
- GM.INJPWB1 and GM.INJPWB2,
- CALC.INJDCB1 and CALC.INJPWB2,
and post a log...
sanity check:
GM.INJPWB1 and GM.INJPWB2 should range up to ~16 ms at 6000 rpm,
at which time CALC.INJDCB1 and CALC.INJDCB2 should be somewhere around ~80%.

Are there any calc pids using those...? If not we can create a pair.
Joe I don't know if there is any
Can you help me create the needed pids ?
