Hello Guys

First, im from Germany, so my English will not be the best. Sorry for that.

And this is my Problem:

Two Weeks ago i upgrated my ECM-Link firmware.
From this point on, i had some Issues with it.
When i drive the car, and i hit 6K RPM it will abruptly stop accelerating and the ECMlog said InjDuty Drops from this Point.

Every gear, always at 6k rpm.
RevLimiter is Set to 7,5k Rpm,

Tried different Spark Plugs from bpr7es to br8es
Gapped them.
Did a boost leak Test.
nothing helped :/

it runs and drives Perfect from 1000-5000rpm But at 5500-6000 the Problem starts.

did someone had the same Problems?
And maybe has a Solution?

i can add a Log too, if needet

Best wishes.
 
Look at the ALS and see if antilag is set at or around 6000 rpm.
Also check the "Launch Limit" under "RPM/TPS".
Can you post a log of the issue?
 
Heyhey
ALS is set to 5050 but it is not activated.
Launch Limit is set to 7500.

Here is a LOG from today, the problem starts at around "156,000" secs.
Throt.Pos. shows 100% but it wont accelerate while InjDuty is going down.

I looked at your log and after 4300 rpm, your AFR's start to go PIG RICH down to 9.8 or so at about 6k. Lean that tune out from 4300 to 6k and keep the AFR's around 11.1-11.5 under WOT. I think she is so rich that she just says "NO MORE".
Good luck, keep us informed.

Okay, i will check this out.
i think i have to figure out why my car starts to go that rich.
Here is a 4 weeks old LOG. you can see a 3th and 4th gear pull starting at 800,900 sec.
Same settings, changed nothing except the firmware update. it drove well up to 7500rpm at this time :(
