Anyone happen to know if the '730 has a input for oil temp? I wanna repin my vette to a '730 next week, and forgot until now that the vette has a few extra inputs.


Is the '730 and '727 basicly identical as far as pinouts, or does the '730 loose a few inputs/drivers ?

A 727 is just a water resistant version of a 730.
Hmm, maybe just pull the PCBs out of the two ecms and compare the traces to see where they line up, pin wise.

 

I'd do that, but I don't have a '727 in my possession, and I figured rather than buy one I'd ask on here if someone knew.

"F12" would be the one.
350 ohm pull up, "U6-channel 1
Code already exists in AUJP for the temp and outputs in the standard datastream as word 38.

 

Hrmm.. I can't seem to find which pin on the 165 it is. I wonder if on the MAF cars, the oil temp is just wired to the gauge?

-- Joe

 

You are correct.. the 165 does not have an Oil Temp input, it is just the gauge on the dash. the sensor is also different on the 90-91 7727 cars.. it is a 3 wire.. I found that out swapping from a 89 to 91 dash and electronics

Hope that helps
