G'day chaps,
Quick question
Does anyone know what or how the idle is controlled on a g13bb, Mine idles high, and I'd like to bring it down. Sometimes it idles fine, other times its 1500 odd. No I don't have a vaccuum leak either.
Next question, does anyone know the tacho output on the ecu? I don't have one at the moment, And i'd like to wire it up to the sierra dash if possible.
That is all
Thanks

I'm glad you are getting around to fixing these problems! When I had it, it never idled that high. Have you got a Jimny service manual?
I think Spamwell hooked up his sierra with a jimny tacho input, dont know how though.

I use a baleno one, with the baleno twin coil motor...
The g13bbs are twin coil also. So they should be similar. Tried hunting down a jim cluster?

Hmmm, may possibly have to do some investigation myself then!
Currently it has four bent rods. Hydraulic'd it in a river on saturday,
Machine shop has bits coming for it, should have new rods, rings & bearings friday arvo.
Then I'll be back onto the idle issue and tacho. Has anyone got a jimny ecu pin out for g13bb? and / or service manual?
Cheers guys, Simon.

g16b does this when the MAF is a bit dirty, are they a similar setup?

Nope, map unfortunately. One thing I did notice is the idle is alot lower when the alternator is connected, but I've checked my charge rate and sense wire to the alt, and is working fine!

Re-set your base idle, it should have a air bypass screw in the throttle body, just unplug the IAC & adjust the screw till you get the idle you want, then plug it back in..
I run mine disconnected all the time, just run's off base idle, even with P/s..
