Thanks! I put more details here
http://www.hptuners.com/forum/showthread.php?58421-VCM-Suite-3-2-is-here!&p=446481#post446481

I used values from a previous tune to workaround the issue for now,...

Same issue, it will accept a larger value (like the tire diameter) but if I put in the 7.29 value the multiplier field says "ERR" and the wizard no longer works.

Also having some strange issues with the Gear/Tire Wizard... trying to change to 3.90s from stock 3.42 gearing (stock tire) but it's not working as expected and I'm not sure what's happening.
...

Thank you guys for the help with this... Spent the past week logging and modifying the VE Main table. Hopefully all this effort pays off. :)

Stioch/current ratio @ rpm... got it. Thank you for the help...its seems obvious now. I guess with the MAF the AFR ends up near 12.5 because its compensating somehow.

I had hoped the stock tune...

Ok, update...MAF is failed now for sure (MIL, no data, removed from config on my interface)...without even hooking up my HPTuners to log my wide band is reporting mid 11s at WOT.... FML... I have...

I verified on the wide band gauge in car that the numbers were in the 11s. Are you saying the PCM didn't fail out correctly and was still trying to use the MAF or that the scanner information could...

Can anyone clear this up for me? I noticed during logging that I was only seeing .71 g/cyl around 5100rpm (which is where I stopped making power on the dyno) then it falls off and after reviewing...

Fair enough... lowered number of items and everything is working just fine again.

Thanks!

Thanks for the feedback... I attached the current tune to the post you looked at so you can see where things are now. As far as IATs it was a pretty typical summer day here and I was hot lapping...

Looks like I need to log less data?? I will remove a few PIDs and see if that corrects the issue. In...

I added some diagnostic PIDs because my car is just 'off' and I cant seem to find the problem. After some logging this morning I am seeing some very strange things happening and hopefully I just...

Bump... went back to stock tune and made some changes. AFR seems to be "ok"...timing added....

Attached logs and config... any thoughts? The log has 3 passes... the 2nd pass I tried to...

I set mine to match the stock c5 Z06 limiter and fuel cutoff (6599 and 6600 iirc)... there is a stock hpt file in the repo for a C5 Z06 you can use as reference.

PLX wideband pulls... Not sure if this is useful but if someone could take a look. Is any data other than 4th gear WOT useful? It's much easier to get data for the lower gears around here.
...

Update: PLX Wideband installed. I put the stock tune back in and I'm seeing 12.1-12.5 at WOT... It appears to start near 12.7 and goes to 12.1 as the RPMs climb. Starting to warm up here (just...

True... Actual elevation here is 640ft and DA that day was -2888ft. 12F and snowing. Thankfully the shop was warm that morning. :). I should have more this week if the weather holds.

I would be willing to buy the numbers of the peak power wasn't off the mark by a lot (peak power happened at a much lower rpm than expected), mph at the track just isn't there and it wasn't a Dynojet...

Thanks for the info guys. Should be meeting with tuner this week (another 6 inches of snow on the way so wont be early this week as I had thought). Hopefully it is just the tune and a good tune...

Sorry completely forgot I don't have a signature here.

I have a real tuner who is going to work with me... I just fear there is something mechanical that I have overlooked but nothing stands out to me. It had a tail pipe sensor and the AFR the first...

Any thoughts? This was done on a dynojet 224x 4th gear pull.

AFR on the first pull was bad so there was a quick adjustment made in HPTuners but it didn't help power at all.
...

Sorry I didn't realize that. I'll pull one of my previous logs and see what happens. Thanks.

I gave this a shot with data recorded on the Dyno... Doesn't seem to match up, what am I doing wrong?

I called this morning and spoke with the dealership.. looks like 100.00 for a software upgrade that only they have. Hopefully that's all it takes.


Thanks!
