What hp were you seeing with Torrie?

 

264whp

 

Not sure if i setup vDyno correctly but here is the two pulls combined

 

Cool, let me now how the self tuning goes!

 

The boost is holding very nicely but I am surprised to the see the calculated airflow only stay at 24 lbs/min. Are the ambient temperatures very high?

 

ambient was 64* last night. IAT's were around 74-79* IIRC. I also have the Turbosmart IWG-70

 

Do you have the other cyl corrections viewed? You're pulling 4 degrees on cyl 1. Cyl 3 is usually the worst in my car so I try to log/gauge 1&3.

Cool stuff man. Nice to see boost numbers that hold

I got a revised tune about an hour after I sent Randy the datalogs so on the next logging pull I will check those off.


I gotta say logging with the AP is lightyears better than the SCT X3. It's even better than the APv2. The V2 is slow and laggy.

 

The Vdyno plots also don't line up with 24 lbs of airflow and line up much better with what I expect to see from this upgraded turbo and the timing you are running.

 

A larger than stock TB could be throwing the mass flow calcs off. Lower pressure drop across the TB = lower mass flow rate. I was thinking he had a bullet TB

 

Absolutely it will. Should make it a rule to post the modifications on the car when posting logs. The larger TB will still not account for the airflow staying flat

 

very cool ST3, is there a link you can send me for more info on the modded K03? Id like to see what all it entails

Did you change tunes for each log? I noticed that the first log showed boost slightly above 25psi and the second log showed boost at almost 23psi.

In your log is the "charge air temp.(F)" column the same as IAT? It showed the charge air temp increase 39.8F and 35F respectively.

 

Anyone notice the 2900psi?

 

So this explains some of the extra fueling headroom being discussed. That is a A LOT of pressure headroom.

 

Nice IAT's look good, and the turbo hangs in much better for the long run! It holds a very steady linear boost through out the rpm's Excellent

 

he has a light weight flywheel. does that make any difference in load calcs or timing advance strategy?

 

No, I don't think so. "Load" is a VE air flow calc thats derived from pressure measurement and airflow models. Timing control wouldn't know the difference
Misfire detection is the only thing I can think of that maybe influenced by a lighter flywheel.

 

Oh and my mods are the turbo and FMIC upgrade, catless DP and straight pipe.

 

Ok guys, aside from what is already recorded, what more should I log?

I still haven't had time to even look at my car so follow up pulls and updates from the new tune will be sometime next week

 

So do you have a modified throttle body? A different sized turbo should not throw the airflow model off this severely. Take a couple of logs including LTFT and STFT and actual load.

 

The airflow will most likely continue to be off until Braden sorts out the corresponding model.

 

I think someone else brought up the tb? He didn't say anything about a modified one himself, I don't think.
