Re: M3.3.1 413
Hi JAS, Ok keep us informed. I hope you could provide some pictures, pistons, rings, head and plugs also. We could try to diag all together what happen and learn from this bad experience. The good point is that you can now buy a thicker headgasket to push a little bit more the pressure safely. good ...

Re: M3.3.1 413
hi guys thanks Olafu for your feedback, this look coherent. There is no reason to have a WOT map if we unplugged the lambda probe. I'm curious to know if the "02 off check box" in the XDF is normal function of the ECU, i mean if it have been plan as a function by bosch ? Or is the xdf modi...

Re: M3.3.1 413
Hi JAS,
Can you please confirm that you can read 100% of the LIVE DATA with AUTOCOM on your M50.
It's a 20 pin round connector using ADS protocole ?
I try to do it with Carsoft but i can only diagnose the ecu not read live data.
Thanks

As all moderne engine have electronics sensors, a portable scope is a good investment. even to repair or found the speed frequency signal, check ECU. it's a must tool to have.

Re: M3.3.1 413
i don't think you can check the duty cycle % in tunerpro.
You have to take the scope or even a good multimeter than can make the measurement of frequency and dutycycle.
Some automotive multimeter can do it, anyway digital scope are really abordable nowadays.
thanks for sharing your results

Re: Wideband O2 for E36 325i motronic 3.3.1 turbo
hi gitto, the AFR is a very important tool, because you will base your set up on your reading. so the quality, realiability and stability is more than important to know what you are doing. M50 is strong, but don't forget you will work on a turbo set up ! Old tuners in car factory, or old speed shop ...

hi JAS, Happy to see you joining my thread, for the m50 turbo conversion fans :) From what i know, and if i'm not wrong, the maf voltage can go up to 5.0volts, but the ECU input can only accept 4.5 volt. That mean you are already saturating the input and the ECU is unable to see how much air is goin...

Re: Rescaling K-value and AT-question
Hi JAS, the new k value is just the cc value difference : 190/540 = 0.352 original k value is 1.00 normally. You need to be sure of the exact value of the original injectors and compare them at same pressure. Our M50 was 165cc injectors. I don't think there is differente software revision for the 62...
