Thanks Bill, sent an email to support yesterday, no response as yet. Why is it that a firmware update failure renders the unit unusable? The v3.6 software forced the update but then turned it into...

I had to buy a new laptop for tuning, so I did and installed v3.6 of the VCM suite. But now when I go to save the tune file it fails with a message that says "Polling Failed". I've verified that...

Tried all those things before contacting you.

So what kind of software forces you to apply a firmware update and then turns your MPVI into a brick when it fails? This has cost me hundreds of...

I'm hundreds of miles from home and my MPVI Pro is a brick due to a firmware update failure!!!

This same damn thing has just happened to me....I'm 200 miles from home trying to tune a car and this BS happens. WTF!!!!!!!

Will do, thanks!

That's the problem....searching for Z06 and LS7

Is anyone able to get any results using the search feature on this forum? Returns nada every time for me.

No one?

Guys, I'm going to put heads, cam, headers on my 2011 Z06 Corvette (LS7) and I'm looking for a tune file for a Z06 with similar modifications I can use as a starting point. Anyone have one I can...

Is the custom 2bar HPT OS susceptible to this: http://www.hptuners.com/forum/showthread.php?p=109682#post109682

Guys, I just saw this http://www.hptuners.com/forum/showthread.php?p=109682#post109682 in the sticky section. Related?

WOW, bet that was a bear to diagnose! I suppose monitoring for a drop in ignition voltage with HPT might give a hint to this problem.

I e-mailed them to you Chris.

FYI, I just replaced the custom 2.5 bar tune file with the previous MAF only E38 tune and PE mode is entered on command. Sure looks like a problem with the custom 2.5 bar OS.

Yes, I understand and have done that, but the OS delays entry to PE for some reason (regardless of whether it's in MAF, SD, or hybrid). I think this is causing the lean condition and preventing...

I'm using the E38 custom 3bar OS and it's not entering PE as it should. I'm not sure if it's the beta or the custom OS, but it's one of them.

There is no knock retard and I didn't hear any pinging. I'm not at WOT when this happens.

Trouble starts at frame 7662 and I got out of the throttle soon after.

I think you're on to something, if you look at the attached log at frame 7626 the commanded afr goes to 11.74 but the wideband says the afr remains 14.6x.

Tune is attached too.

Here's what I've got. 2010 Camaro SS 6 speed manual with a 419ci LS3 with twin turbo's generating a peak of 12psi boost. I recently upgraded to the HPT custom 3-bar OS and am in the process of...

He started getting bad belt slip when he went to a 3.25" pulley on the stock 6-rib pulleys. He was going to upgrade to an 8-rib kit for around $1,800 but given the difficulty changing all the...

Thanks 10_SS. It's a twin turbo with 12 lbs of boost. The motor is 419ci with 9.7:1 compression.

I noticed the PE delay rpm was at 2000 too, but thought it was well above that when I was getting...

Gents,
Attached is a tune file for a 2010 Camaro, it's upgraded with the HPT custom version that replaces the virtual VE with a real VE. I've tuned the cruising areas of the VE and the MAF and...

Yea, well for the money I spent taking this car to a tuner I could have bought another brand new "built" motor. I got tired of dropping $300+ dollars every time I changed a component or just wanted...
