Hi! Sorry for my bad english.
I have a BMW e39, 530d 193 ps from 2001. 76mm straight pipe without cat.

There's a modified ECU on it, but I'm not happy with it! I didn't do it.
The credentilals of the tuned file:
Turbo: Garett gtb2260v@28 psi (i have an 30 psi map sensor)
Rail pressure: 1500 bar
Dose: 100mg

My probelms:
1. No smoke, its good news to baby polar bear, but not for me. Im afraid the mixture is too por, and the temperature is too high, absolute no smoke, at any rev, nothing, looks like a petrol engine car. And it will ruin the engine in the long run.
2. Sometimes when i keep the rev in 2200rpm, any gear, example 5th, the car is freeze. No respond for gas, no matter where i go. And a few secon the car is back to the "live" and respons the throwing. Mysterious...

It would be nice if someone wrote for me a new ecu file.
I would be grateful for it

I didnt attach my ecu file, because its a dead end.I think.
Once again thanks!
