P28 ecu have been using s300 for about year now. the last up date changed the values in the vlotage/lambda conversion table. the question is why is there 3 boxes now for voltage? i changed the setting to 0v = 10.00 and 5v = 20.00 but what goes in the 3rd option? voltage settings are for a PLX ...

Finally got a new distributor, and you seem to be right. After removing the MSD coil, I did a full throttle run all the way to 7500 rpm and the datalog had no issues.

Thanks for the help trouble shooting.

If it is the MSD, what ignition system do you recommend that will not effect the ECU?
Other then the datalog stopping, the car runs perfectly fine.

I wired up my boost control solenoid, and when i went out to test it the data logger stop recording and then wouldn't recognize my ecu. had to turn my computer off and car off to get it to see the ecu again.
I then deselected the boost control and the same thing happened.
The sparks plugs should be ...

I also have be wondering about this. I had AC but I removed it to fit my turbo in. if i hit the AC button in the cabin it lights up but when i check on my laptop the ac still says off. How can I get the cabin ac button to reach the ecu?
