Mods are in my sig. These pics were taken from a dyno tune I had done on saturday to dial in my vafc2. More than likely these numbers were taken in 2nd gear, because that's the gear they were shooting for when adjusting the vafc. I'm not concerned about peak numbers so much as the air/fuel line. The guy tuning my car said he was aiming for 12.6 to 12.8 afr, so that in case the computer fights the vafc I won't run too lean. What do you guys think?

Forgot to ask...My next mod will be the nwp spacers in a few months. Will that small of a mod screw with my tune? Would I need to re-tune at that point?

Do you have the actual runfiles?

It certainly does look like 2nd gear due to the smoothness of the curve and the low torque #.

So, was this done with our without the ex. cutout?

Strong peak numbers for sure, especially in 2nd gear with minimal mods.


Our ECU's have yet to show they try and compensate for an AFC, so I wouldn't worry too much about that.

I don't think you will need to retune with the spacers, I didn't notice a difference in my AFR after I installed mine.

It be nice to see what kind of #'s you wpuold pull with the spacers and in 3rd gear.

No catback I take it?... decent numbers, but like stated above this would seen like a 2nd gear dyno as the wtq seem to be on the lower side of what it should be

anything done to the Exhaust side will need a re-tune. actually anything you do benefits from a tune, on the Air / Fuel sides......

Also why is the air fuel at 12.5? I though we benefit from 13.1 ? I may be wrong.

^^^ in those ranges and on a car to car basis

I don't have my runfiles. I plan to do a third gear dyno run once I do install spacers. Out of curiosity how do you do that? Get the car fast enough so it will downshift to third? My cutout was open on these runs.

you lock it into 3rd gear, then you get it to 3800 and roll on the throttle.

3500, get the most out of it, I think I've even done it earlier.


Call the shop and ask them to send your runfiles to you.

When I was auto I rolled into it just after it passed 3k.

yes 3200 is what i ran it from

jr schultz

Thanx. I emailed the shop for the runfiles. I'll post them up once I get them.

NmexMAX

Maybe you should send them to me ...

jr schultz

I will if/when I get them.
