Default HELP - SD tuning w/HPT

I'm so frustrated right now. Basically just got up and left the car in the garage.

Hopefully someone sees what I'm doing wrong on this. I can't even get the car to run to begin SD tuning.



Thanks for any ideas...

My timing stays crazy low too for some reason... ~10* @ idle?

Well found my high octane wasn't copied over the low octane table, but its not a massive difference... going to flash and see what it does.

Because you have your dtc's set so that the maf won't fail upon startup you might not be going into speed density mode, you might want to fix that so at least your sure its going into SD.

Why is your TPS reading 23% at idle in a non ETC car? Also your map reading is 90+kpa which is super high at idle.

I have to hold the throttle down that far to keep it running @ all...

I have no idea. What could cause that? I installed a cam, 232/238 .599/.601 on a 113 lsa. Would that do it?

They're set to SES enable & option "1 - MIL on second error"... where else do I look?

Your AFR error seems to average about -20%. Make a large to the VE of 15% or so through the idle area to help get it running. This is a normal part of roughing in a VE if you have no suitable base. Just getting fueling closer will get things back to stable, assuming they were previously stable with the MAF hooked up.

Bill found the magic issue... I've got 42lb injectors. Somehow my KPA table got lost in the mix and set back to stock. I set it up correctly... and whoa, check that out... everything acts much more like its supposed to!

Bill also gave the advise to set the DTCs to set on the first MIL rather than the 2nd. This puts you into SD mode on the first start, rather than the 2nd.
