I'm not able to find the PRLDSW scalar in the CRAI8 xdf, does anywone know what to search for?
There's no FN035, but FN035A is properly populated with maximum load at 0"vac/0boost. Load at WOT goes up to ~1.42, but perload never exceeds 1.00 in the datalog.
The MAF curve is dialed in well, but I'm not getting enough power enrichment under boost, and I don't want to tear into the base fuel table if I can easily fix PERLOAD to go into the part of table it should be using.

Re: Perload switch
On the foxbody it's a flag, not in scalars.

Re: Perload switch
Thank you! I was definitely looking in the wrong spot, but it's also not listed in flags, so I'm still not sure what I should do with my perload situation.

Re: Perload switch
I know it will take a while but just look at everything. Read the comments as you hover of them. Hopefully the Decipha himself will assist soon.

Re: Perload switch
oh ok, it's running fine, but the MAF is still calibrated up to get enough fuel in boost. I guess I just need to understand what the perload logic is so I can set up the fuel table properly. Right now perload clips at 1.00
