HP Tuners Tune File for Turbo Setup
Hey guys,
I'm wondering if anyone has a tune for their turbo setup, perferaby one for a 416 stroker motor in HP Tuners format. I want to use it just for comparison with my tune; I've had to disable the dynamic airflow section of my tune to get it running marginally well and I want to see if that's what others have had to do. Thanks, Steve |

Did you check Hptuners tune depository? Might get lucky.

I have a 07 Corvette TT on stock engine tune file but I don't think that will help. With that engine I would force pure MAF mode.

Steve, just had a discussion with a gentleman over the weekend about an 08 TT LS7 vette built by a Big name shop. In order to get it to run satisfactorily he ended up having to switch to an aftermarket MAF and switching to MAF only. I believe he was in the 11-1200HP range. He also mentioned having to do a good amount of tweaking to transient fueling. I know it isn't really what you're looking for but it confirms Roger's opinion and at least gives you something to think about.

Sounds like you need to convert the OS to a 2 bar with that setup. This will give you a actual VE table to work off of along with a boost enrichment table as well. I have a turbo file using maf only as well.
Call me in the am. I can email both of them to you. Chris 678-551-8422 |

That vette should of been converted to a 2.5bar OS system to give them a actual VE tables as well as a boost enrichment. Much better fuel control. Gets rid of the Virtual VE all together. Chris |

I agree and suggested changing OS (Normally runs about 6-8lbs, 15+ lb capable), but it was delivered to him with the factory OS retuned... not up to par. Up to this point he has been fooling around working with it himself to fix issues and was surprisingly knowledgeable. Definitely the best and easiest way would be an upgraded OS, but if running low-moderate boost you can make it work on MAF.

I think an aftermarket MAF may be in order, do you have any idea what he used? Thanks for the reply. |

It's especially noticeable in transient fueling...if you dial in MAF and VE, the original transient stuff seems to function better...when you go MAF only that side of the tune seems to need a lot more attention...at least in my experience.

Mike, any tips on tuning the VE coefficients?
