Thanks Hart! I'm a believer in detailed threads with updates and follow-up's to replies. I have threads on other forums I reply to when people comment years later and say they found my thread from a Google search. Good documentation is just another way to pay it forward to everyone else out there.
Ed, I hope you had a great weekend. I'm back to pick your brain again. I played around with the tune on Saturday. I changed the injector data back to stock with the exception of my flow rate table left scaled for 85-lb/hr @58psi. I came out to a car that would start and die or not start at all. I started making adjustments to the cold temps in the idle airflow tables because it was very cold that day. I even tried throwing in the last good tune I had with the incorrect injector data and had the same issue. I put the the tune back in with the correct injector data and wound up having to throttle the pedal to keep the car running. Once I got it running, I logged the lambda error and started making adjustments to the MAF table. It seemed to get better after a few adjustments and my wideband reading started leaning out and getting closer to stoich. I pulled plug #1 and #8, both looked very clean and had no abnormal signs of poor combustion. Frustrated with the car not idling on its own and having a date with my wife to go to the Chicago Auto Show, I called it a day.
Now I'm back out in the garage with ambient temps at 42* as opposed to 15* on Saturday. I tried to fire up the car and still not able to get it to idle on its own. I throttled the pedal to keep it running and get the engine warmed up for a minute or so. Still stalls when ECT above 100*. I made a log of this. Looking at the log, I noticed the MAF Hz not coming down to 0 when the car stalls out. For example, if the car stalls out with the MAF at 2,550Hz, the sensor just hangs at 2,550Hz and throws off my lamba error log. I've attached the current tune and the log from today. Take a look at it and let me know what you see/suggest. I'm really struggling to get this thing to idle properly and feel once I do, things will get much easier.
Thanks Ed!
