I have gotten programming from PCM4less but it seems to be a lil off..running really rich fouling a few plugs..also I have 30 SV0's what fuel pressure do I need to run? the heads flow 250@500 ..the car just isn't trapping very good speeds at all...I can e-mail the file..please let me know or if you have a similar file I can view to compare..mods are in sig thank you

Hmm...if you're fouling plugs it might not be a tuning issue.
If you want to send me the bin file I'll take a look.
Not saying I'll find anything, but I will look.

Also, IMHO fuel pressure should be 42-43 psi static. Don't touch it after that.

 

did you try changing the heat range on your plugs 1sT? Cheap enough fix to try be4 you go retuning your PCM. I had the same problem be4 with fouling plugs. Just changed them from 2 temp ranged colder to just 1 temp range below factory. Fixed the prob

 

i have a NX wet kit I am going to install soon so I am gonna change out the plugs anyway. Tripin..what plugs are you using?.however the car is just off somehow..not sure if it is a fuel issue or timing advance..

i will shoot you the file nd let you look at it..maybe lean it out some..thanks

 

I would like to swap files with you if you like. Mine was for a hotcam kit with stock heads. Headers, CAI, ect. I am assuming your VE tables are going to be larger than mine but it sounds like yours are set too high anyway if you are fouling plugs. Would be nice to compare side by side to see what is being changed and by how much. If this is true then it may actually run better if you use my VE values without changing anything else in your bin but that. Drop me an email if you want to swap. I am getting my heads worked on now and been trying to figure what values are going to work best so I need various bin files for car that have had head work. Because I see a ported MAF and head work in your sig I bet the VE tables were just over done alittle.
