I'm looking for a patch that will reset my BLM to 128 on PE mode. I searched DIY-EFI and didn't come up with anything. Any good programmers out there want to help me edit the source code?

Reset your BLM to 128 in PE mode? I'm not sure what you mean.

You know how the INT resets to 128 on accel pump? I'm looking to make the BLM reset to 128 when it enters PE mode.

It does that already. No need for a patch. PE mode happens when you get on the throttle pretty fast. Hopefully you've disabled the PE lag that's incorperated with the 7747 ecm (being used in a truck). When you snap the throttle open the o2 sensor becomes useless and so the BLM goes to 128 and from there the computer does some calculations to the VE tables to make your specific air fuel ratios. Like if you set the AFR to always be 14.7 under PE or WOT mode then you're tables won't be changed by the ecm. It'll just go to BLM 128 and do the stock tables. This is why you never see a N/a engine with it's AFR set to anything above 14.7. At least I have yet to see an eprom with say 15 or 16 AFR under PE mode.
