I am currently having a problem that I can't seem to fix. I have a crate 350 with a comp cam designed for TPI the number is 12-314-4 if anyone would like to look it up. I have 24# Accel injectors, Flow Tech headers and Y pipe and 3in flowmaster cat back with no cat. I have no emissions here. I'm using the aujm bin file modified only by injector constant and I have a very lean idle (160 BLM). I have BLM values between 122 and 130 in most other ranges, but it idles very rough and stumbles on takeoff. I've tried many different injector constants, and none seem to help the idle. I can change the battery voltage correction and richen idle, but it richens everything else as well. Am I overlooking something easy??

 

My guess is that you may need to play with the MAF Table #1.
I brought up a similar prom code and couldn't find an idle enrichment factor like I have in my $8D mask. Maybe we both have an outdated $6E mask?
You'd be better off posting this in the DIY-Prom board. A search there may provide you with the answers you're looking for.

 

I am assuming that $8D is a SD bin?? I'm not familiar with it. I'll give DIY a try. Thanks

 

Yeah. $8D is a SD bin.

 

DIY-EFI.org is gone as far as I can tell. It there anywhere else I can check? The link from Moates takes me to a page that doesn't look anything like a fuely tuner site.

Right here on our own board.

 

I feel silly now. I was just reading something in that forum and thought, Wow, he's really gonna think I'm an idiot. I only signed up last night and I'm not familiar with all the forums yet. Sorry for the inconvenience.
