I'm building a v8 efi fiero, I have have just came across a megasquirt 2 and was wondering if anyone using one has figured out how to get the speedometer working after the stock computer is gone??
I'm using a 92 non e 4t60

I suggest you download the online pdf 86 service manual.

It has the schematics relating to the speedo and the ECM (and all the rest of the wiring).

You will probably need something like this to convert the pulse rate.

We just had this discussion recently... MegaSquirt 2 does not have a VSS input...

Basically, removing the stock ECM has no effect on the speedo. You don't even have to touch the speedo wiring.
