Soooo which Corvette are you selling?

Are you just going to get it smogged by a blind tech?

Will take it to a ref to try and get the sticker.  Smog I'm not concerned about.  The car was built right in regards to emissions.  All readiness checks should work fine.

Clutch is chattering.  That better stop or I'm going to firebomb Monster.  Last thing I want to do is a clutch swap...

Need to plug in a wideband and get working on the tune, but it seems to be running very well!  Trying to stay out of power enrichment for the moment.  The clutch is supposed to take 500 miles to break in...I guess I should go easier on it or it may chatter forever :/

Yea let the clutch break in and see what happens. What Monster clutch is it?

I forgot you were doing the BAR deal.

Monster stage 2. It's a little heavy compared to the vette, but not bad. The extra effort is mostly in the master cylinder I'd say. The chatter should go away. Pretty common and I've not heard of one chattering after a good break in.

I hooked up a wideband tonight.  It must be super coincidental but the fueling is actually pretty spot on.  STFT's are less than 3% and power enrichment follows just where it's supposed to.

Going to dive into some VE tuning as I think it's pretty far out in places, but the MAF curve seems really good.

Only gone into PE at 55% throttle so far.  Plants you pretty good when it pours some fuel to it.  Definitely has some beans... Can't wait to put my foot in it.

Anyone have experience with the GTO gas pedal?  The throttle curve feels like shit compared to the vette :(

What ECM are you running?  Sorry I can't remember.  I have an '06 GTO pedal and E40 ECM and don't have a complaint of pedal progression.

Running basically an LS3 (LQ4 block, .030 over, LS3 heads/Intake mani and injectors/Vette intake, cam).....

It's an e40 ecm. I'm going to do some VE tuning tonight if I have time.  I think it's pretty out of whack in places due to it being a 4" stroke. (ls2 block, 4 inch stroke, ls3 top end, samberg intake, mild cam). Lots of changes from stock.

That should help tip in be a bit crisper I hope.

So the complaint is tip-in response not pedal to torque conversion?  I have mine running MAF only until I can find the time to tune the VE.  At least we still have a table of VE instead of the coeffiecients in the later ECU's....

Yeah the top of the pedal travel does very little. It's really just takeoff and rev matching that feels crappy.

Once moving it feels fine.

By crappy do you mean that it takes a lot of pedal travel to get going from a stop, and the final 25% all feels about the same? I have always wondered if you could adjust the exponential of the throttle curve.. Everything I have read in HP tuner forums (not a ton) said "Dont' mess with it!"
If you could adjust it it could get you more fine control, especially in cars without TC.

As an aside, if you want to feel crappy DBW response go drive a new GM truck or Tahoe/Suburban. Holy crap it is horrible, and really laggy. I am sure they did it for improved fuel economy for those that jab at the gas pedal, but it sucks.

It takes a lot of travel and it's not very responsive to blipping the gas, but if you hold the pedal there it does respond. Just laggy like you said. Hoping that's just a dead spot in the tune I can fix.

Nice! Now hood that bitch so it doesn't look like 90% of the 2JZ swaps out there  :yay:

Oh I want to... Gonna smog it first and then do a new intake tube which fits.
