93 Ecu into 90 (tach)

[phillabaum03]

So i put a 93 ecu into my 90. I swapped the wires that where listed on vfaq, everything works fine but my tach. Now i did some searching but really couldnt come up with any solutions. Do i need a 91-94 coil pack? And if so what do i do about the plugs being different. Does anyone have any solutions. Its kinda gettin irratating not knowing what rpms im at. Thanks

Wow.. Maybe ill just hook a shift light up and use that. I dont feel like going and looking for all those parts, including changing a guage cluster.

Anything is possible but I believe in supporting the person who put in the effort, as long as the price isn't outrageous.
