Hi guys,
Im new to the forum and thought you may be the best place to search answers for.

Last year i swapped in a 1.8vvt into my 91´NA, ran in it on the stock 1.6 ecu, swapped out all the electrics according to the fm instructions. Ran okay but not great.

This winter the project has been to make the engine bay top notch! Painted the bay, cleaned and painted all engine parts, deleted or relocated accesories such as all fluid tanks and relays.

I am currently wiring in a Maxxecu street as it is what is most commonly used here in Sweden as a Standalone ecu for most cars, lots of tuners and help easily available. But there is not much people that has done this to their miata so a few car specific questions are still not answered...
Stock engine harness has been completely removed from the chassie, and will be replaced by a custom one.
On the maxxecu there is an GP output for the tachometer that needs to be wired in, but i cant seem to where. Found some threads in here to wire it into the igniter but that has been removed as I´m going to run a sequntial spark with NGK cop.
Is there anyone that has wired in a maxxecu into their NA in here that could help a lost soul?
