roadspike, could you post the details on that "Time Since Engaging Starter" table.
I'd like to find it on my ROM (88580013)

I'm running FIC 1050 and your settings has helped with cold start at 30F. Ive improved the warm start with values 3.6 but not enough.

Who else running FIC 1050 has solved the warm start issue?

I have; both on 91 and E85. I found that if I opened the throttle significantly it would catch. Therefore I was injecting too much fuel. I kept lowing the cranking primer until it would start. My numbers are _very_ low above 50 degrees F.

EDIT: Here's my E85 "Cranking Encrichment IPW Adder (Main)" for 96530706

132.752
57.184
40.104
13.824
1.2
0.2
0.2
0.2
0.2

EDIT2: FIC1050s scaled to 731cc for E85.

I only have the address from Mr. Fred's advanced fuel control thread for the 88590015 rom. You'll need to pm him for help on that rom id sorry.

Note that i changed mine to slowly die off instead of stock stepping down.

I realize I'm dragging this tread back from the depths but my issue applies directly.

I'd been having issues with warm starts on E85 but none with cold starts. This went on for a long time, so much so that I stopped using e85 for a year. I just stared using it again after my buddy told me about the Injector Cranking IPW tables. However on my table the numbers are all jumbled up and I can only see one digit and then dots. We played around with different values, making changes to the whole table all at once, and noticed that the lower the number the better it started. Zeroing out the table made it start right away when the engine is warm. Then we zeroed out just the bottom half, leaving the top half how it was, and it had issues again. Then we zeroed out just the top half, leaving the bottom half how it was and it worked. Problem solved. However, now I have terrible issues starting when the engine is cold, something I never had before. Because the table is jumbled and unreadable, I don't know which rows to mess with to adjust only the cold starts without messing up the warm starts. Any ideas?

This is my table before i made any changes.
