Hello,
So with the car idling, the timing is where it should be. Once I start driving (part throttle) spark goes down to zero and once I let off the throttle at speed the timing goes back to where...

engine diag>airflow>top left

Pretty sure a '10 6.2 doesn't have DOD at least my '10 6.2 Silverado didn't. It does how ever VVT tho.

I had those codes happen to me all the time. I upped the slave to 40% boom stop acting up.

Do a throttle body relearn via the scanner -> http://www.hptuners.com/forum/showthread.php?60666-Help-on-how-to-relearn-throttle-with-HP-scanner&highlight=throttle+relearn

If that don't work then...

OK, here's today's log. Hybrid with it set to 2k off. The WOT starts at 7:25

I look at my VVE and I see what y'all said it looked like shit lol.

64190

OK powerhop is now disabled. Put the car in MAF only today and no problem with the airmass dropping. Put the car in hybrid mode the airmass drop and so did the IDC. Put the car in SD no problem...

LS7 427, Heads, cam, headers and cold air.



More than likely torque limit... I have it disable now so I'll do some testing.



That graph took me like 5 hours to figure it out lol :doh:

Here's the dyno graph and you can see the big dip right be for 4,000 :confused:

I guess I'll fail the MAF and record a run. Fail the VVE and record and compare em'

Ok I see what your both are saying. I feel the car is ~40 horse power lower then what other cars are making with the same setup. Track times reflect it too. Only doing 133ish when it should be...

So I put the car on the dyno and around 4,000 where the car switch to MAF from VVE the cylinder aimass drops like a rock. So is this telling me to keep the car in speed density?

1. Write entire has to be performed each time.

2. I'm at 40%

3. Settings go back to stock. I found out the hard way by using EFI live.

4. Have no ideer

Hmmm ok...I know what I'll be doing very soon.

Does the car buck when ever you get off the throttle? If so zero out [ECM] 12670 - Idle Overspeed Spark vs. RPM Error (Coastdown). This helped my car a lot.

Disregard this post I was think ls1/ls7 to ls3 map and clearly you have a ls3.

If the vette is a manual I doubt it will start unless you do a clutch relearn.
Did you do a write entire when you disable the vats?

Had this happen to a buddies car...won't start unless you did...

LOL map goes to 120. Send tech the tune and have them add "Slave Segment Data". Once they work their magic it will be under the edit menu. This gets ride of the REP

I was getting sick of this issue...never knew when it would happen for me and it's fixed!

Dammit...I've been watch this thread for awhile and I will finally have time to start playing with these settings. My '08 E38 don't have Closed Loop Integrator Delay vs. Airflow Mode...but the '10...

Thank you who invented the search button...:worship:61415

Was going to ask this...need pics :shrug:

IMO I would have more timing at idle.

download a 09 corvette tune from the Tune Repository and go to

Fuel>power enrichment>pe throttle/pedal hot change those numbers to the tune you download to...

I'll be watching this very closely.

Micheal D are you planing on a 50/50 or straight 100% meth?

I've been racking my brain on this calculator deal...how and where do you edit it?
