LS7 Procharger Help

[xtrememotorsports]

I need some help with tuning a 2009 ZO6 Procharged car any help would be great.

[Mr. P.]

Are you saying you need help purchasing software? Are you saying you need help setting up a wideband? Are you saying you need help reading a tune? Are you saying you need help knowing what tables in the PCM to modify?

What help are you asking for, exactly?

Mr. P.

Ok, so then you're familiar with doing AutoVE...

The E67/E38 ECM's don't have VE tables, they have VE polynomials...

The EFILive tunetool provides Virtual VE tables which render the VE polynomial factors in a virtual VE surface...

See this thread: showthread.php?t=8961

Post #38 contains the latest VVE tutorial pdf.

Adjusting the VVE's is not the same as doing AutoVE, but it uses some of the same concepts.

Have a read thru the VVE pdf's and see how you go...

By the time you read this, some other people will have added suggestions, comments, expertise.

Disable VVE, go MAF!
Install a 2.5 bar map sensor from a cobalt and scale it.
Deal with the dynamic section carefully and you are good to go
Install 60# inj.
Otherwise the engine will break.

Do you have dyno?

Car is too sensitive with timing adv...... what boost r u heading?

AFR shouldn't be more than 11.4 !!!!

LS7 block is too weak and break easy, just be careful.

just finished tuning my 07 Z06 ls7 with a 6psi procharger setup. If you need any info or help let me know the specifics.

Hi robertryan23,

Good job

Some questions:
- install a MAP sensor...?
- tune VVE...?
- tune MAF (or are you MAF-less)...?
- which injectors do you have...?
- how did you determine timing...?
- did you tune with the aid of a dyno...?
