Alright, so i completed my swap earlier this year and have just been driving around with some minor problems but now they are starting to get to me.
First and foremost. the car runs, engine will start 100% of the time and will not die at all, although sometimes it gets close.
Background:
The motor is an obd2a B18c GSR
The chassis is an obd2b EM1
The wiring harness used came off of my b16a2 (obd2b)
The ECU is an obd2a b18c GSR and is being run using an obd2b to obd2a conversion harness
The secondary butterfly valve has not been wired up
No CEL at all
The problems:
1.) Tachometer does not work, i imagine because its an obd2a Dizzy and an obd2b plug but am not sure
2.) Really really rough idle, sometimes at idle the RPMs will bounce from 200 to about 1000 (this is a guess because as #1 says, the tach does not work) as if there is a vacuum leak somewhere, i cant find the leak at all. the nipple on the throttle body has been capped off. its worth mentioning that after about a minute or so the bouncing idle will become steady at.about 600 (slightly higher than normal).
other times, and i have only noticed this when the car is warm, the idle will stay at close to 2000-3000rpms steady (again, my best guess).
3.) How do i wire up my secondary butterfly valve?
