overboosted on this run. lol

Any ideas on what would cause this ? This keeps happening when i pass people on the road. I cannot replicate it on my normal logging runs.

Below is my stage 0 run just to see if there's anything weird with the car itself.

May honestly go back to JB4 life.

Are these on pump gas? Is20 I'm assuming. Pretty high psi for pump. I run 27ish on an ethanol tune. Based on the stage 0 file I'm gonna say it's your tune. Try taking some logs from 3500 to redline and see how it is.

My 93 tune is perfect. Happy with the final hp on the Mustang. Great dd tune. This e30 tune hauls ass. I'll get on it passing traffic and look down and my AP says 16-17psi. Surprises me every time knowing I have another ten pounds to give. Can't wait to get the e30 tune on a dyno

May I take a look at one of your 93 tune logs? I would like to compare it with what I have.

i read a few recent pages of this. did i understand right that even the cobb brand ots itself is having some issues? or is that mostly with some of the companies trying to modify it?

Here are some logs from the Cobb OTS IS38 file. I am not happy about the big dip in the boost. It is very noticeable and makes the car feel like a slug until almost 4500 RPM.

Edit:
It could be an issue with the wastegate adjustment
I am seeing 3.481v

This says I should see 3.5-3.589

It passes adaptation, but may need a little tweak. I wonder if that .019v variance could really cause this issue.

My oil temp hasn't changed since being tuned. the car isn't pushed hard enough for it to affect oil temps. If I was on a road course then, the additional power would affect my oil temps, but street driving doesn't push the car hard enough.

Hi Folks - I just installed the Cobb (stratified) ECU and DSG tunes. About to start datalogging, but wonder what DSG tune would be best for this. Right now i'm running the DSG sport tune. Also, I can't seem to switch DSG tunes (either the other DSG maps are greyed out or now missing). Any insight is appreciated!

Also, I'll contribute and post some logs later on (with the stratified tune).

Yes all you have to do is scroll down to the tunes tab on accessport and click enter then scroll down to restore ots maps. Once done the day maps will be selectable again from accessport. Had the same problem after initial day flash but this solved it.

I just got my AccessPort installed, I cannot find the option for auto on/off with ignition. After doing some research this may not be possible with out AccessPort. Is this true? If so what is everyone doing with the AccessPort when the car is turned off. Are you unplugging it every time?
