Can someone take a look at their palm and write down the injector pulse widths for the various temperatures in the default start map? I had the data cable move and break the connection while uploading a map to the ECU, and it ended up deleting all start maps from my saves. For now I've just guessed what my modified numbers were from memory, and it's actually been working well. Still, I'd like to get the cold start values closer to stock. Judging from this picture from the Rtek manual, I'd say I'm injecting less than half of the stock amount of fuel on startup for temps 77* and up.

 

The stock map is retarded rich. hence why low comp cars flood all the time.

 

Yes, I know it is. I have been using a modified start map from day 1, but I'd still like to know what it was before all the data got erased. The cold start data points were fine; it's just the hot start ones that need editing.

 

I've been using around 8ms for my hot starts and it seems to work well enough

 

That's what I have it set to right now. 8ms for 149*, 221* & 257*, and then I just tapered it up as the temperature values drop.

The old thread above has a post by me about half way down the first page and I made some remarks about how long the duty cycle was during hot starts with and without the start signal being seen by the ECU.

Seems the afm is used if the start signal isn't seen and the afm is used for fuel instead of the Start Fuel Map internal to the ECU. Seems around 6ms worked for me everytime when the engine was hot. See the Palm values in my post there. By the way, I figured this start fuel map out before it was offered by RTEK and was using a Fluke 88 tapped to the ECU to show the diff in ms b/t using and not using the Start Fuel Map internal to the ECU (braggard be me).
