PCM Diagnostics & Tuning - Heelp!!!

im switching from 27lb ls1 injectors to a 41lb? ls3 injectors in a ls1 car... Im struggling finding the injector offset table. i already have the flow rate vs pressure table.

is there any other tables that i need??? HEELP PLEASE!

Can you look up an oem ls3 tune in the repository for the missing data.

yea that's part of the problem, I downloaded a stock 2010 camaro 6.2 tune to compare to my ls1's tune and basically all the injector tables are written differently soo I'm unable to copy/paste I'm assuming this is do to the computer change to e38 pcm's, basically I need a ls1 tuned for ls3 injectors that I can copy/paste or someone to tell me exactly what to change...

Also I'm useing hp tuners.

Are you running an aftermarket referenced regulator, or the stock fuel setup?

Try this out(highlight copy and paste the yellow highlighted cells)... Somebody can double check me if they wish because I just threw it together quick.

**I made the assumption that you are running the factory fuel system @ 60 psi. If you aren't I would need to redo the spreadsheet.

Thanks man that's exactly what we were looking for, we have a corvette filter with internal reguator. The actual pressure measured at the rail is aprox. 58-60psi if that makes any difference to anything? And also with this table and flow rate vs kpa is that the only changes I need to make?

Double check the short pulse adder, min pulse, and short pulse limit then give it a whirl. I don't have my hptuner computer with me now, so I would have to check later.
