This is a "custom" burned chip for a miniram w/ stock heads/LT4 cam...... and I'm using it as the basis to start tuning for the higher rpms of my Stealth Ram/Pro Heads/Comp XE262. The PE tables are very different than others I've seen. Here they are:

PE vs TMP
Deg F---%

306------22.66
262------22.66
219------22.66
176------22.66
133------22.66
46--------33.59
8----------43.75

Why are all the PE vs RPm in negatives? I would think that you'd want a posative number to add such and such a percet to the fuel? Maybe I have it backwards? I want to know what way to go to add more fuel up high.

Car should be much faster than it is. This is one of the things I need to know about.
Thanks guys!

I'm confused! No one knows which way to turn the tables?

I have to turn my fuel pressure up to 46psi with 24lb injectors to keep from getting a lean pop or two when I step on the gas. This peggs my blms to 112 all the time and sucks the gas milage.

Although at WOT my o2 mv are 920-1000 so I'm not too overly rich at WOT so I need to back the pressure down till my cruise BLMs are 128 ish and then add gas to the enrichments to get rid of the lean pop.

I know how to use the AE but not the PE. HELP!?

All the negative numbers are doing is counteracting the PE vs Coolant temp F/A adder.
Right now reducing that negative number will add fuel until you reach zero then use positive #'s to add.
Notice the tables are richer where peak torque peak should be around. IE: -00
