Hi,

I'm after a MR30 (L24E 1/1985 ) Wiring Diagram, The diagram I have is not the same as whats appears to be in the car, when I look at the connector from the EFI to the relays / ignition etc, the picture I have has a 9 pin plug, and uses 6 wires ( see the picture 1 ), the car has a 8 pin plug and uses the 8 pins (like picture 2)

any help would be welcome

Ok, point of clarification.

The round plug uses all 9 pins, it's just that the ECU part only uses 6; that's why only 6 are shown in the diagram. 1 of the extras is definitely for tacho, don't recall immediately the other 2 (1 is water temp gauge, 1 to go).

You may have to do some probing with a multi-meter to determine which wire goes where.

Sorry can't be of more asssitance right now. I'll have alook at mine tonight when I get home. Might be able to toss some more light on the problem.

Ok, other 3 pins are (9-pin plug):

Black/Green - Tacho

White - BCCD valve (in throttle body)

Yellow/White - temp gauge

Maybe the later models didn't use the BCCD valve.

Do you have a "Full" wiring diagram you can post ?

I have the same manual you have.

I know about this because I just recently wired in a Wolf 3D, and had to work out which bits of loom were re-usable.

Do you have the "full" wiring diagram that you can share, this diagram is as rare as hell on the Net

      RB25DE NEO with Haltech ECU

      For fuelling the Haltechs have O2WB fuel controllers. Very useful for helping tuning VE and correcting for *small* mistakes. Of course if your injector/cam/trigger/sensor data is just wrong (or for a GTT which is not a GT) then you will get impossible reactions to things. I am sure you know this already but the reason people don't typically put haltechs (or any Aftermarket ECU) on GT's is because there's practically no real gains to be had - So this knowledge won't be commonplace.

      Can someone tell me if the cracks seen in the rear sway bar bushings in these photo's is unacceptable from a roadworthy point of view?

      Shouldn't need a "base map" for anything other than guidance to ignition tuning. You just need the engine capacity right, the injector size right, and something, almost anything, for a VE map. On an NA engine, fuelling is almost completely a function of load signal & rpm. It should run and drive with a completely flat fuel map. It will be too lean under load, but that's easily fixed. We used to tune all ECUs without any base map. There were no such things (until someone had tuned a near stock engine on one, and then they had a "base map".

      Duncan's V37.......race car?

      By Kinkstaah · Posted

      What did you actually buy/how much did it cost? When I got mine in like.. 2017...? 2019? the aim was to run Torque for gauges via ODB2 and things like Track Addict/Laptimers/Dashcam/Reversecam/Spotify etc. Mine never broke, but I wonder if you've got the same needs (it sounds like it). Cause I liked the idea of being able to do anything with it. That said, yours also cost 3x the cost of what I spent so... food for thought.

      For me there is a massive difference in manufacturer or big brand crippled android (Sony, Kenwood etc) vs the sort of thing I've installed here, which is basically just a tablet in DIN form factor with open Android, and the other model of course is mirroring - Android Auto/Carplay. I hate the locked down manufacturer and AA options where they decide what apps I'm allowed to install, including the Launcher but also importantly things like Ecutek (for this car) or Real Dash (Stagea) are not supported. Plus those crippled versions tend to be slower due to both overheads and lower spec hardware. On the other hand, when this breaks I'll likely be in trouble for support....but how is that different to owning an Infiniti anyway
