I ended up just bandaiding it. The lighter flywheel and harmonic balancer seem to make resly made the motor more sensitive to torque changes. And I wish i would have put stock pump in it. But ohwell...

so I've noticed on my 2002 manual vette while tuning it. That it seems to be very dependent on oil temps. What I mean is. If I let it idle from cold to hot to get idle data the oil temps raise with...

I'm having an issue where on hot starts the car has positive stit around 1.2 g/s and then it just slowly goes back to around +- .5 g/s where I tuned it to. But during that time which is a minute or...

I figured it out should of notcied it yesterday. Ve was way to rich leaned it up and it was fine.

I will tomorrow ill get some good logs to post and the tune im nust not at the car or my computer right now

6.0 woth a tick stage 2 sns torque max cam. And typhoon intake manifold and chinese throttle body. Runs good after you hold the gas and let it idle i did the raf table today and some part throttle...

Thank you I didn't think about that. I'll make sure I change both to make sure. Which one does it actually use or does it use both. Do these cars have a manifold switch i didn't think they did. So...

OK I didn't change the low htz fail setting. I'll do that just in case. When is the boost os patch needed. He one that makes the injector flow rate read into boost.

I have the maf fail high set at 5 htz and dynamic disable at 7000 and reenable at 6900. I Am getting the DTC set for the maf fail. First start it was showing realy lean everywhere. So I tried just...

OK thanks. So do you think I should zero the coefficients and get rid of burst knock when I blend them

Ok im just used the older stuff I've only tuned maybe five cars. The first three I done were all sd tunes a cammed 5.3 and a ls1 etc so much easier to do. Now that they have the vve tool I guess i...

Could you elaborate please I'm used to older ecms that have actual ve tables and are alot more simple. If I have the rpm disable set low enough to never use the Ve tables. Do the prediction...

I also do not see the intake manifold volume in the tune anywhere.

OK I thought the prediction coefficients only were used when being blended. With I habe the high rpm disable at 400 rpm so I would never use the vve. So it still uses it when it's maf only. I'll have...

It's in maf only. And I completely re tuned the car the other week after the headers and flex kit were installed. Stfts were on the negative side when finished. And pe
was bout .2 leaner than...

2011 ctsv 2.5 upper. Ported snout. Stainless works headers. Afraid intake. Id1000s. And dsx flex fuel kit. Car will not free rev smoothly it will immediately stutter when. You pop the throttle then...

OK so what do people normally do just tune to desired afr in just third gear or fourth gear. And let first and second be slightly leaner. Or tune it till like second gear is to your desired afr and...

has any one noticed it gets richer the faster you go. like 12.0 afrs in second gear then 11.8 in third and 11.6 in fourth as an example. car in question is an 2011 ctsv. so am i correct that there is...

so let it run ten minutes or go wot is the answer. anyone ever figure out what the actual cause is. doing a buddies 2011 v first e67 i have done. real inconsistent fueling. maf only tune also

nobody

ve table ha been messed with alot anything after 4400 is realy some guessing with little data in those regions except for the wot areas its the first car ive tuned. ve table isnt real smooth through...

base advance pid. Where does this value come from. At idle it says 46 to 50 just trying to find out where this value is from. if its needed its a 2011 ctsv that im scanning
