Thanks for the answer. To be clear, this car is not mine and I'm not the tuner. I made this topic to help a friend. Every 20vt here built with the same way, but this A4 doesn't work.
If you can check the file also. Thanks again.

*edit*
I had a look at the log and its utterly useless.

Unless its patched for a map sensor in the intake manifold, your "mafless" tune will always be wrong, you have no atmospheric density compensation. VCDS logs are garbage, you can not possibly find any issue with those crap 3 channel logs at such a slow capture speed. Im being blunt for a reason, sugar coating it wont help you. Fit a genuine maf sensor, get some real logs using vehical or me7 logger, and if closed loop is dropping out during full throttle, check your bts and knock correction. If bts is set too rich and request goes below the internal minimum lambda value, closed loop gets switched off. Same goes for knock correction, if the ecu is pulling a shit ton of timing and dumping fuel trying to save the engine, you will have the same result, lambda switched off.

Hi everyone, i have an Audi A4 20vt avj engine, gtx 2867 turbo, maffless tune, bosch 630cc injectors, and all necesary peripherals.
The car face an issue, after almost 5000 rpm goes rich to 0,75 lambda. We have check everything. All components and sensors are new.
Returness fuel system replaced with normal fuel rail. I attach log, ori and tune file. Any help apreciated.

No.

The only reason it is slow is because Tony hasn't given me perms to the server itself.

It is unlikely offering him money will change that. He's just not really around.

Tony's not logged in for almost a year. Do you have any other means of communication with him?
I'm pretty sure at some point his AWS payment method will expire and the Route53 + EC2 instance will get shutdown.
Does the forum's SMF version have support for backups through the admin panel? If so, please grab a backup every once in a while - just in case.

I made some small research of Volvo Gen 3 Haldex flash.

Was finally able to write to the eep using CSpin P4.7. I also desoldered the jumper on the back of the ecu I think that’s what did the trick. The car started up finally. This originally became a problem when I read the ecu with nefmoto it finished reading but then the car wouldn’t start I flashed a ori file still no start so I read the eeprom 95P08 and found it had a checksum error. So after removing the jumper on the back of the ecu and running ME7EEPROM - - bootmode 95P08 -w -p1 - - CSpin P4.7 95P08.bin I finally got a good write and car started. I also flashed a ori flash file in bootmode galletto 1260 make sure that was completed. Putting my experience out here cause the me7.1.1 is a bit trickier than the me7.5 and me7.1 that have the 95040 eeprom. I don’t work on many a6 or all road that use me7.1.1 so had to learn a couple things real quick. Couldn’t have done it without the forum and info from past posts from some gansters. Thanx to everyone in the forum as always.
