Difference between pin 45 from ign and the 49 from the relay is about 0.5V. So If I changed it around the ECU would be about 0.20V diff than the battery.

Hi With the way the ECU power is setup, the voltage difference is about 0.70v on my car. Most aftermarket ECU's only need power on pin 45 unlike the stock system which takes power from the ign to pin 45, then gnd's pin 16 for the 2x relays to kick in and then feed power into pins 49/59. Has anyone rewired the relays so that they feed power into pin 45, which would mean the ECU voltage and injector voltage should be the same for better tuning? This would involve switching the relays from gnd to 12v switched and then use a feed from the relay into pin 45.

Thanks. I found your post https://www.sau.com.au/forums/topic/482872-r32-gtr-gts4-largely-gtst-wiring-diagram-scans

Hi My google foo is weak, would anyone have the pinouts/wiring diagram for the 3x white plugs by the ECU. 2x 12p and 1x16p Thanks

Looks like its an m10 thread. Does anyone have a block they could measure the surface area around the knock sensor? The donut according to Plex needs 22mm of surface area to contact. I know on some cars, people just drill out the bosch from m8 to m10. Wonder if it can be done on an RB. The JZ have an adapter stud, but they are m12.

Hi How has everyone with aftermarket ecu's mounted their bosch donut knock sensors? Thanks in advance.

Thanks, that is where I'm stuck. Easy enough to get speed to the ECU, but its getting it to the cluster as stock it would go from gearbox to cluster to ecu.

Hi For those that have done a cd009 conversion in the r32, how have you got the speedo working on the cluster? Thanks

Managed to find some abs hubs, you can see the hole for the sensor sits on the inside.

I'm just toying with the idea as the ECU can do it. Most likely playing with it on track or street. Maybe 2 front sensors then and the VSS

I'll have to look that up in my MaxxECU. I'm just using the gearbox for driven wheel speed.

Perfect, this what I was after. Did you just use an R32 abs ring and grind every second tooth down? I looked into g sensors and gps, but a lot of people say they react too slow, however it must work some how for the AWD guys that have no option of a non driven wheel speed sensor.

Something along the lines of a Motec hall sensor. https://www.motec.com.au/ac-sn-crankcamspeed/sn-crankcamspeed-hs/ Not sure there is much room to mount one look at the back of the studs the way the knuckle is. I need to look at it on the car. That should be more help to anyone else that looks at this post.

Any recommended sensors and mounting?

Has anyone fitted a wheel speed sensor to a rwd R32? I'd like to add traction control from my ecu and need a non driven wheel speed sensor. Ive tried to find some abs front hubs and changing the sensor but having no luck

Hi I know the r32 rb25de has larger ports on the intake manifold gasket. Could someone please confirm the plenum gasket if it is larger than the rb20 one or if they are the same. Basically I want to know if I can use an rb20det ffp top half on my bottom r32 rb25de runners. Thanks

Hi Has anyone built a sub box to fit around the rear strut brace, Ideally I could still fit 2 wheels in the spare wheel well and my surge tank to the right. Thanks

Thanks!

Voltage was the same as the battery when running around 12.8. Battery was 12.3 when cold

Hi I've just installed an Apexi RSM, this uses the ign power wire from the ecu as its source. The voltage reported on the RSM with the fan on 1 and headlights on, can drop down to around 12.4v and at idle around 11.8v. Is my alternator on the way out? What should the operating voltage be? around 13.8v? Going to get the multimeter out to check voltage at the battery tonight.

Hi I'm working on a r32 gts auto which is now manual. I know the cable that has 2 plugs on it for the auto display and shifter. But I've come across this plug https://dl.dropboxusercontent.com/u/1574371/IMG_20160422_205430.jpg It sits close to it, so its just to the left of the clutch. It has 3x constant 12v pins on it. Does anyone know what it is, can't find a place for it anywhere. Thanks in advance

Come on, you must love the middle inside bolt

Wow those look awesome, I was only looking through the narva catalogue

Does anyone have pics of how they've added a fusebox and relays in the engbay. I want to tidy my setup I have at the moment. fuel pump sub amp thermo fan thermo fan 2 low beam high beam Thanks in advance

Thanks figured that out about the fan pretty quick looking at the wiring. I earthed the temp switch and could hear the relay clicking, but it wouldn't fire up the fan. I put 12v direct to the fan and it spun up.
