    Help with tune 8051 95 $EE

    Hi Guys
    Im new here and to tuning. First off i have a 97z that i converted to obd1(tunerpro), Mods include : pacesetter lts & ory, magnaflow 3", racetronix 255 pump with hotwire kit(48 psi), morroso cai, stock maf with screen still in place. i previously had the obd2(jet dst) computer tuned so i copied and pasted to the obd1 95 tune.
    Would anyone be willing to help me out with my tune? Ive included the jet dst tune from the obd2 pcm and also where im at now with it and a datalog.
    The .zip can be removed from the file name

    Thanks Jonathon

    i can help you a bit;

    i take it you read my writeup, since you didn't break BLM by disabling ccp? ;)

    by your timing table and your log, i assume you're not running a stock cam anymore. your timing map is a bit steep in mid to low vacuum, even for a big cam, under very light throttle isnt it a bit surgy?

    your BLMS are consistently a bit lean, you should fatten your maf table up a little bit.

    other than that, i looked through your bin and its a great start.

    your timing goes from 26 degrees to 40 degrees @ light throttle tip-in below 1000 rpm. shoot your tuner. if you tuned it, i apologize. in that case load a stock timing table and enjoy some drivability while you learn to tune conservatively.

    I think us OBDII 350 people are a dying breed, not just LT1.

    well im broke, but lt1s and their parts just keep getting cheaper as everyone's wrecking them, throwing them out and putting ls1s in everything.. so i can't see giving up on them any time soon...... personally i think its a great platform (not that i wouldnt buy an ls1 if i had a bunch of money...)
