Shutting Off at Idle
Posted: Wed Jun 01, 2022 12:14 pm
Hello,
My car is having an intermittent issue with shutting off at idle randomly, and moreso when there is more load on the engine (AC).
I first experienced the issue when ambient temps here in southern California began to rise, and with the car on pump gas and dialing the dead times (ID1000), which I read through a previous thread and think I got pretty close, the car randomly shut off once in about 95 degree heat and I attributed it to the alternator rectifier, which I swapped out along with the brush holder and voltage regulator.
I have subsequently began tuning for E85 and I'm able to get part throttle and full throttle all where they should be, but it now shuts off at idle every time. I disabled ELD thinking it was voltage-related, didn't help. It's less likely to do it with AC off and almost guaranteed with AC on and on the logs I can't really determine a reason as to why.
I will attach current calibration and related logs
