IAC counts are in the 30's at full temp, pegged at 160 during cold start. I 99% of the time i get an initial fire and within a few msec it will die, i assume during the change over to the OL table,...

Hi All,

I have been working on cold start (0-32*F) tuning. Have a 94 LT1. I scaled the first and second pulse widths based on the change on injector size and that seemed to help, but i still need...

I notice that table only goes up to 6400 RPM, will it just pull the same value in the 6400 cell above 6400?

kur4o,

Have you ever looked at a table to pull timing for nitrous using a pin on the pcm to activate?

kur4o,

would there be a way to add only the open loop idle v2 to Steve's EEX4.1 xdf?

Appreciate the feedback, looks like it was set at 50 MPH default. Is cell 16 the open loop target AFR table? So I will tune idle fueling in this table only correct?

Sounds good, if i just apply the patch and dont touch mph threshold it will just go to CL once 1MPH is reached right?

one other question - do i always need to use this xdf for tune updates or can...

I have a 94 auto, which one should I be using? I dont want to control it via a pcm pin, I want it in open loop at 0 TPS all th time so i think it is between these two.
