hello I have a ms2 v3.0 .when testing on the jimstim v1.5 everything works normal but the 02 sensor is tied into map sensor readings . I am running the latest 3.4.1 firmware . I have built a few other ecus and never had this issue so not sure where to look to resolve this .
thanks
Jake

Check for solder blobs and stray flux. This seems like a hardware short.

Re: map sensor tied to 02 readings on jimstim
I have gone over the board and checked for any blobs of soldier... same result after some double checking the board and cleanup . Is there a specific area I can focus on the board that would tie the map and 02 signal together ? I have not run into this before so i am lost on where to pinpoint the issue
thanks Jake

Re: map sensor tied to 02 readings on jimstim
found the issue that tied my map sensor to the o2 readings . I tested on the stim and put light pressure on the cpu (u1 ) area around pins 21 and found the map readings stabilized with added pressure re soldered and all is well so far
