Is this only for trans fan ??
You cant change parameter in editor this is what ecu use.
Okay you can set temp.

The eehack show the speed.

maby take the trans temp instead of engine temp

Its a 350 lt1 from corvette c4 1994 and pcm 16181333.

The pcm pinout show 4000 ppm on 2 chart i looked at.
So pcm strecthes or shorts the pulse to match speedo ?
Trying to understand the 4000 ppm output.
Does the ecm send 4000 ppm to speedo when you change values after tire change or change output ppm to example 4030 ppm ?
