Edis and coolest temp sensor twitching
Edis and coolest temp sensor twitching
I have an ms2 3.00 on my olds 455 with edis 8
I'm running it through the relay board and that is what I have narrowed down my problem to.
Everything was fine until I followed the mega manule for edis
"If you are using the relay board with a v3 main board:
the SAW signal connects to the S5 terminal (#11 on the 20 position terminal strip) on the relay board, it comes from DB37 pin 36 (make sure you have a wire connecting pin 36 to pin 36 in the MegaSquirt/relay board connecting cable),
the PIP signal connects to the Tach terminal (#15 on the 20 position terminal strip) on the relay board, it goes to DB37 pin 24."
Since I did this my clt temps are jumping around with each revolution.
When I go to my extra harness directly to the sensor it reads perfect
Then I took my multi meter and I had continuity between pin 36 and the coolest temp terminal
Any ideas???

The ms2 tests good with the stim and with the harness
As soon as the relay board was plugged in things went screwy
