need help with tune datalog inside

http://www.mediafire.com/?yh0whzsz8ffjj7o

theres the datalog. i am having rich issues and i believe the timing is too far advanced. can someone please look at this and help me adjust the tune through tunerpro? i would be willing too pay for tuning through email. i have all software and chip burner but really dont know what i am doing tuning wise. this is my 3rd tune from solomon and it seems too be rich no matter what he changes, any help is appreciated thank you. i have software too tune but am completely new to it and im afraid ill mess it up without proper guidance. thanks for your time, would like too add the car only made 263 hp at 5800 rpms. the signature is wrong because my builder messed up and put 1.5 rr's in so cam is nowhere near the correct lift. also my tune elevation is 262 feet and the mustang dyno is at 2237 feet. i feel even though its auto it still seems very low. i also believe i have a heater core plugged. would that raise the temp of the intake and tb? they seem too get very heatsoaked quickly yet the car does not overheat. has a 185 degree thermostat and runs at 187 too 190. never gets above 205 stopped in traffic on the hottest days

Re: need help with tune datalog inside

You have a rich idle , probably due to not enough air, your IAC is pegged at 160 wide open and you are maintaining Idle speed by using the idle overspeed/underspeed timing table. You need to crank the TB open a bit more to let the IAC control idle. Getting more air in there should cure the rich idle . Your timing at higher/lower MAP (high load) looks OK not out of whack for your mods. You are not getting any retard or knock detected. Ve tables must be OK as the ST BLM's are OK, but the LT's trims indicate rich on the right side, I would reset the ECM and see how the LT's look after a couple of driving cycles. Your O2's take a while to start switching, but that's typical of a non heated '93 setup. Injector DC peaks at 62% at 100% TPS closing in at the top (85%) but fueling still looks good. I Can't see anything that would cause your low power. I wondering if the rich idle has messed up the O2's, the voltage swing looks good, but sometimes they start switching slower when they get fouled. If you had an AFR gauge I would suggest pulling the O2 connectors off and seeing how it runs in open loop. Are you sure the valve train is adjusted correctly ?
