We watched the car live on the road again. And we realized that the car advance value is constantly pulling itself back. The retraction angle is up to 6 abgles after 3 angles, and up to 9 angles after 5,000 cycles.

Didn't you have any fault codes?

unfortunately :( we canceled the oxygen sensor and tried it. We did a DME reset. We tried a new brain. We did a software copy from another e89. There was no improvement. my ridiculous car goes to 100 in 11 seconds and there is no fault code and our trials were inconclusive. .

I went to pick up the car today. but the master said that wastgate opens itself after 1500 rpm in the tests. I cannot determine why he opened it, he said.

Just like you said, we have already kept all the lines to compression, zero leakage. ECU not requesting boost.

we monitored the real road test with the computer connected to the car. We checked all values such as calculated and actual crank speed, torque, fuel suction, air suction. All values correspond exactly to the request and calculation of the ECU. but here the ECU turbo pressure does not exceed 0.5...

my waste valve is electronic. vacuum pump brake and exhaust flap opening and closing work. but my vacuum pump is constantly leaving oil in the faulty engine cover. but this does not affect the car going because wastgate is electronic, not solenoid.

we did this on the road. Of course we tested it on dyno first. Neither on the road nor on the dyno any advance value was less or more than requested. But the problem we identified here is that the ECU never requested pressure above 0.5 bar from the turbo. and in my opinion, whatever the source...

i couldnt understand what you mean exactl. can you explain this more ?

i will check this side thank you.

yes i laughed at your humor: D i will check: D

Hello, first of all, thank you very much for your interest. We recorded the car live with a programmer, the ECU provides all the data it requests from the mechanic. but the ECU certainly does not demand pressure above 0.5 bar from the turbo. Our turbine is a zero never used turbocharger. And we...

Hello, first of all, thank you for your interest. After 5 months of mechanical checks, we focused ourselves on the ECU, but no errors were found in the ECU, we experimented with a new brain, the car still did not react positively. Thereupon, we pulled the brain software from the same car and...

Hello friends; my vehicle is 20i e89 2013 z4. It has been 6 months since I bought the vehicle, but I could not use it yet. because the car can go from 0 to 100 kilometers in 11 seconds. and absolutely no error codes. bmw inspected the services and they said it was normal and left me alone with...
