Need some guidance OLSD tuning I have a 98 Camaro, (see sig)
This is a bracket race car where consistency is important. I have been using LS1edit to do all my tuning and old version of autotap to do my scanning.
I finally got EFIlive. I done a read on the PCM and would like some guidance fixing this tune.
I want to make a OLSD tune. I know it is currently wacked up, but that was the best I could do using LS1edit and autotap.
Could someone please take a look at the tune and guide me in fixing this mess..lol
Specs:
383 CI stock stroke by 4.10 bore
42lb SVO injectors
L92 cnc'd heads
LS3 intake
Thanks,
Rick

Hi Rick,
Would this help: http://download.efilive.com/Tutorial...20Tutorial.pdf
Just follow the parts that say 1998.
I assume you have a wideband... the procedure is the same as you did with LS1edit and AutoTap, except that now the EFILive scantool allows you to filter your log and create a map which is then multiplied into your Backup VE table, makes the process go quicker and is less error prone.
Instead of bumping by 15%, figure say 10%... your first log will tell you if you are in the ballpark... if you're not, start again with a different %.
You may need to use RedHardSupra's speadsheet to calculate the IFR table for your injectors.
