simple proof is that usa spec cars came with fixed resistor value, so some retard was involved, i cant say how much thou.

What I'd like to do on the street is let the LH see actual eng. temp. (for good fuel economy) and let the EZL see only what I want it to see via a resistor (which should help both fuel economy and power---the EZL is way too prone to pull ign. advance at the slightest little rise in temp). I just don't know which pins go where.
Can't do it. The systems have logic built in to compare the two values. If they are significantly different, the computers assume a faulty sensor, and will use the higher of the two values.

"

well on my M103 thats what i did, one value for the timing and one for injection since i didn't much fuel i would run a small resistor value for the injection. dunno if its the same for ur v8.

as for finding the pin to the timing box its fairly easy. just do a connectivity test from the temp pin to one of the plugs in the EZL unit on the fender.
