new turner problems over here lol

[s10guy]

i swapped a 2007 gen 4 LS in a 1993 s10. i was having issues with the obd2 port but i got a bench harness to tune to ecm. but anyway i adjusted the idle by watching a lot of you tube videos . the truck will run about 2 or 3 secs and shut back down. it does have a sloppy stage 3 cam. and fabricated intake swap. its 58x . im new to HP tuners and would like any guidance to helping me fix this issue so i can complete the build, im not asking for someone to give me the answers . just need more of a idea of maybe what im over looking or not doing correctly.

Post the tune and logs, only way we can see what you've done so far.

ive tried, i cant figure out how to post my tune file on here.

at the bottom of the reply box click on "go advanced" and then once that loads click on the paper clip "attachment" and ad your files that way.

thank you for the help with that, i will get the file loaded . it probably isnt tune correctly but i made just very minimal changes from what the ecm was set for me. it was supposed to be pretuned with vats deleted .

truck has stock 36.6 lb @58 psi returnless injectors but i just installed a inline fuel pressure gauge and its reading about 58 psi when turning over and holding and trying to fire will run about 3 seconds and shut off .

TBH youlll get more help if you make a post about this in the Gen 4 forum. Im not around my laptop to look at the tune ATM, but will try when im off work. Did you change OS to 2 bar setup since youre running a 2 bar MAP? Have you made ANY VVE or MAF adjustments? Are you wanting to use wide band or narrow band O2s for tuning? Will it stay running if you put your foot on the gas pedal? Do you have a log of startup and the few seconds it does run?

[s10guy]

oh ok. im still trying to figure out these forums , i did change the OS to 2 bar and save it like it said, and i have not made any vve or maf adjustments as far as i know. and i will be running a wide band . currently not installed tho . just put everything on hold until it will run for more then 3 or 4 seconds . and no it still dies even with your foot on the pedal. and i do not have a start up log. i can try to get one today.

can not get a running log with it trying to start because the OBD2 port will not connect. having to tune off of a bench harness

i swapped out the wiring harness with another one . the obd2 port is working with this one . i will post a data log this afternoon of the truck while starting it and running for like 3 sec. hopefully that will help

[horsepowerguru427]
