Strange logger values

[68442]

Just getting this car running, everything seems ok except COOL, AIRT, Baro, batt are all moving erratically. Idle and o2 etc are fine. This is using mmcd logger on a 92 turbo car.

Take a close look at the ECU.

Looks like there might be issues going on with the caps, but then again you know what your looking at. I have a eprom ecu and getting dsmlink v3 so if this one is shot no biggie. Just have to wait a week or so.

The caps are starting to leak but that's not the cause in this case.
May still be the ECU but I can't see all of the ECU and some of the things to check are under the heatsink like the sensor ground.

Try it in a friends car and see if the values still bounce around.

Must have been the ecu, I looked it over close looking for burn tracks but didnt find any. Did get the other ecu in there with dsmlink and it runs fine.
