Im not an IT or programming guy by any means but in order to eliminate possible causes it's standard operating procedure for tech support to make sure the customers device and tune version is using up to date software...you chose not to do that

I suppose it's possible that I had made a tune on newer soft/firm ware than your device was set up for

Add to that that I still think something was wrong with the wastegate actuator

Regardless, this is ending up good right? Im looking to see when you post logs so I can check them out

Temp changes would not make boost change that much....Topher's was massively overboosting in the top end where boost normally tapers...ive never seem that

That's the great thing about closed loop boost control...to a point the boost will be taken care of as long as the target boost was where you want it and his was

Another option here is to offload the SHO and get an STI... I heard those will gap an SHO all day long... ;-)

I was referring to the stuttering issue he is having that I also experience. Unfortunately I have tried to datalog the issue but nothing shows in the datalog..even when it happens during a logging session.  Overboosting is a different issue all together...

I dont think it is a question of corruption.  I think a change in parameters and tune handling is what goes on with device updates.  They must be correcting and improving software performance with the updates, and the tune has to be in sync with the current firmware/software.  This is very common on software platforms.  I have seen this in my custom programming when the platform comes out with updates, suddenly my program starts behaving erratically, UNTIL I read the documentation and update my custom program to comply with the platform's current environment.

I might agree with this if the issue fixed itself in 2 months when it warms up.  But fixed itself IMMEDIATELY after resting the handheld.

It is just way to coincidental.   

My tin hat is on tight for this one.   After the reset every tune worked. Before even stock stuttered which prompted the parts parade.

I'm glad it works I know what fixed it but my tech nature doesn't know the root cause an it BUGS me

Its busted again,  Same behavior.  super bad stuttering under prolonged boost in 2nd and 3rd past 4000 rpm.

it was doing perfect,  multiple starts and stops,  hard driving then normal driving.  but on the way home from Coburg Pizza,  it hiccuped 1x in 2nd.  that made me suspicious so i dropped the mini-me off and went out and gave it a hard push from a stop and sure enough 2nd was a mess past 5000 rpm,  and keeping my foot in third made it start having a seizure after 4000 rpm in third.

No logs,  will try tomorrow. 

there has been no handheld hooked up since the ''fix'' of resetting the SCT. so the only thing that has changed is 'time' on the car.

if this is a bad ecu that losing cell data,  i may have  conniption fit.  i am going to pull all the tunes off the handheld,  then put the good ones back.  and re-flash the car to oem, then back to the good 15 pound tune. 

sigh

What tune revision were you on when it behaved bad?

This one (attached).  It ran for about 36 hours without issue on this tune.  then tonight it regressed.  I want to data log it with both the old config log,  and the new datalog.

F$%k it.. I'm going to get a partial log right now,  it's easy to reproduce at mostly legal speeds for 2nd gear.   

3rd would be better and it would be in range of the issue longer but its to dark. well do that tomorrow.
