Thats not what a graph looks like when timing is being pulled. It's much more choppy. Those are big wide dips in the curve. Any reason for this?

Nice job on a TT with a 7AT. :tup:

How many hours all in done deal, PM please ? was it supply and install or only install

Probably less than ideal VVEL settings... be interesting to see boost and AFR curves overlayed with power and torque output.

BTW, what kind of knock sensor? Resonant or non-resonant? Anyone able to output that from the ECU?

In the original post, the dip from 6,000 to 6,250 rpm was around 25 lb/ft of torque. In the graph that Daniel just posted, the biggest dip is around 40 lb/ft or torque. I don't think that difference defines whether or not it is retarding the timing. That graph looks like a turbo'd vq35 with more boost... conventional camshaft sees torque fall off at high rpms where the vvel keeps pulling. If it is a high boost 3.5, it's retarding more degrees of timing to compensate for the high boost. If you run California's 91 octane vs the 93 octane the rest of the country gets, it will retard more. If your engine is heat soaked when you do the run it will retard the timing even though you've done 5 runs where it didn't retard the timing. Also, when you remap the ECU, if you advance timing aggressively, it's going to have to retard it based on the knock sensor and get choppy. If you map it conservitavely it won't need to retard and your graph will be smooth. Also, if you forget and leave traction control on during your dyno run, it would do the same thing. If you don't have enough weight on the rear end and it's spinning (a little), it would also make a wavy dyno curve. I still say, get the ODB output if it's available.

The waviness can be many things. Something as simple as the boost not holding steady be it the wastegate or boost controller settings (gain, limiter, auto learn logic, etc...) Knock as well. A good way to find out if its knock or engine noise is to log the ignition timing albeit it with Cipher or the dyno equipment if possible. The timing will always start to drop off at the top you just want to make sure it does it according to the IGN maps. Cam timing also plays a good amount (overlap, etc) so VVEL could be it. Although some forced induction VQ37s look smooth as a baby's butt. A good test for knock if logging is not possible is to throw in some 100 octane and see if it smooths out. Logging fuel pressure would also be handy if a pump is having trouble keeping up and also calculating injector duty cycle. AFR would be a good indicator of this.

Also like Phimosis mentioned the way the car is strapped down and the ability for the clutch to hold the power can have an effect. Typically when a clutch slips the graph will look much different.

How does the MAF work on this setup? I have read that the MAF used on the G37/370Z needs to be placed before the FI instead of after. I am not that familiar with the platform, though, so correct me if I am wrong. How should a car with a tune/setup like this do long-term regarding engine durability?

The new Camaro's are no faster than the old (LS1 ) camaros. The GT500 is decently quick, but still way too slow for someone with 450whp in a 3350# car to be "gunning" for. Look for some Z06's.

2010 camaro 12.615@111.60... all stock. with a good driver there just as fast as the new mustang GT's..... there quite a bit quicker than the ls1 camaro. and trap considerably more.

and 450rwhp wont be enough to take down a properly driven z06.
they dyno 430-450rwhp and 420-440tq stock and weigh less. run low 11's. id say 450rwhp for the Z would maybe net it a high 11 maybe 11.8 11.9 range. but thats just a guess. noone seems to be posting drag times with there TT setups

New GT - nice, plenty of potential

Any updates on this 7-AT TT project?

How is it holding up? Mileage driven? Type of driving? Any tweaks necessary? Tranny slippage? Funky smells/sounds/sightings................

Yes there is. The car was not pulling timing. It has clocked about 4k on the mileage. He drove it to PC last week and is loving it. The owner Kerry drives it 0-60 as much as possible. But his brother beats on it when he drives it. His brother has an SS camaro but uses the Z to beat up on people. After tuning the tranny with the Osiris there has not been anymore limp mod. We also added a vented hood to let engine heat escape.

the pictures in the first page arent loading for me.. i assume this is that blue car??

If so that car really is sick.. and yeah its very tame until you 100% gun then oh man.

Ask Tony (2theextreme) he took a ride in it...
when he came back.. he was seriously chewing his finger nails!!!

I can't wait to win the Lotto. :)
