Re: A/F Steadily Goes Rich Until Stall at Idle

Confirmed the problem does not exist in a year-old calibration with live tuning disabled. Also confirmed the problem does not exist in the same file but with live tuning disabled. Said another way, the problem existed on a file with live tuning enabled but the problem does not exist if the same file...

Re: A/F Steadily Goes Rich Until Stall at Idle

No, it does not coincide with the fans. After a long negative terminal pull, the car started and idled for 10+ min without issue. It wasn't until I shut it off and did a hot restart that the problem came back, manifesting as 19:1 AFR and misfires across all cylinders. This appears to electrical, rat...

A/F Steadily Goes Rich Until Stall at Idle

Car was at the track two weekends ago (as it has been many times) and just before a session it was idling, began to nearly die, catch, then idle to near death and repeat. I reflashed the car and attempted to tune it out, but there are/were no anomalies in the tune. I was able to log the STRIM attemp...

Re: Throttle body swaps

Hondata, do you know the years for the Civic SI and the TL-S throttle bodies in this test?

Re: Throttle vs Airflow table

So the table is used at idle, among many other things like overrun, CL/OL transition, and WOT transition. How do changes to this table manifest in idle behavior?

Re: Throttle vs Airflow table

The description in the help is for the Throttle flow vs opening table is insufficient: "In some situations the ECU will need to know the air flow past the throttle body for a certain throttle opening." Can I get an explanation for when the table is active and what effect it has during those conditio...

Re: Timing/Fuel Targets at Idle

Thank you for the timely response. So the timing tables are not active at idle because it is an idle-control strategy but the fuel tables are active? I'll modify the airflow table to see if timing comes and I'll also look further into fuel adjustments. The fuel adjustments didn't appear to affect th...

Timing/Fuel Targets at Idle

I'm looking to understand (and alter) timing and fuel under idle conditions. I have a modified manifold and throttle so the airflow characteristics do not match OEM. As a result, timing is floored at -1/0/1, AFR is relatively stable at 14.7-15.0, and an occasional stumble/misfire can be felt alongsi...

Re: Fuel Trims Wildly Different with Flash Pro

Both logs were started after a period of driving, shutoff, then restarting the car; the morning I drove to Starbucks before starting the log, the afternoon I had been autocrossing. Ambient temp was ~20*F different (50*F in the morning, 70*F in the afternoon). IAT on startup was also 20*F different, ...
