Fuel Injector Speadsheet For LS3 to LS1 Injector

Attachment 18538

ok here is tune car runs lean as and stalls out with ls3 injector settings... confident fuel pressure is fine
ls1b fitted with l98 t-body with xlink and ls3 injectors.

Your are setup to fail the MAF (to run SD/MAF-less), but in C6001 the MAF DTC's are set to Not-Reported... this prevents a MAF DTC frim triggering... with no MAF DTC, the OS does its best to run from the MAF table, if there is no physical MAF then it calculates what the MAF value should be and uses that... the value it calculates is usually wrong.

So set the MAF DTC's in C6001 to either 1-Trip or Non-Emissions, and when you start engine verify that a MAF DTC is immediate.

Do this anyway: measure rail pressure to make sure it is ok.

( That log file shows 26 pid channels... if you're tuning, reduce the pid channel count to 24 )

This solved my problem, for some reason my script file didn't pick this up. Anyway thanks Joe for your help.

The supplied LS3 injector data was also very close to being spot on....

No worries, you're welcome, glad it worked.
