Help with tune 8051 95 $EE

[jthompson122183]

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.

oh do you happen to have the factory bin that you started with, if it's still in original condition? i want it for my collection. i dont have 16210041 yet.

[jthompson122183]

sure did read it.
factory cam.lol and i am getting surge in gear
How did you go about finding what cal id the bin was? i found it online but cant remember where, so i have know clue if its in original condition.
Also would like to thank you for what you've done for us lt1 people we are a dying breed.lol
Your information and tools has helped me understand what is going on in that little aluminum case.lol

i forgot to put calibration ID in my xdf file. its in there now but i havent uploaded the updated version yet, im holding off until there's a few more things fixed. it's 16210041. im working on a chart here http://fbodytech.com/bin/index.html but yours isnt in it yet, that's why i wanted it.

woah then, cowboy...back off that timing. your timing table is out to lunch.

[steveo]

and how'd you get 48psi of fuel pressure? AFPR? are the injector stock?

[steveo]

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...)

Feel the same way about my L31s minus the stock intake.

That was all my doing. I didnt know that i couldnt copy over tables from obd2 to obd1. Its all good now. Started new with a factory 95 bin from steveo site. Would anyone be willing to check out my bin and data log to see if anything looks wrong? im getting a miss or some kind of surge in gear now. new plugs,wires,cap and rotor. My fuel pressure is 48 with no vacuum at the regulator. Also i have another factory bin for steveo. Thanks Jonathon

[steveo]

having trouble opening that zip file for some reason, can you try again?

thanks for that bin, didnt have that one yet, its a b-body one

[jthompson122183]

The .zip extension needs removed. Thanks steveo

rpm is incredibly unstable and it's fighting to maintain it, with iac and timing.

i think one thing you've botched in that bin are the BLM cell boundaries.

you've changed low to 700, mid to 1200, and high to 700. if you look at your log, its jumping between cells at idle since 700rpm is a weird place for a cell boundary.

use 1200, 1500, 2000 for your BLM cell boundaries.

i doubt that's your problem, though.

i notice in your log that your vehicle moves, then stops moving several times at low speed, but your throttle never ever leaves 0%

so what exactly were you doing when you took that log?...
