Just took a gander ant the UpRev site -- looks like they offer full datalogging (cipher) and have full control over all the maps... but I couldn't find confirmation that they can tune VVEL.
Is it really true that even the uprev software can't tune VVEL on our car??? That seems like a huge tuning limitation if true  |
No problem...My turbo cars run from 10.8 to 11.5 under boost. Forced induction always requires more fuel as it is used to cool the charge and reduce potential for detonation..
I make a boost controller for Audi's that lets the cars boost safely to 24psi with a chipped program enhancing the fuel and timing. Without the chip, 18psi is about max...
On the VVEL tuning I could see a lot of guys really screwing up their cars. Be careful what you wish for....
