Hey guys,

Before I get blasted for not searching, I have tried on this forum, google as well as flicking through the R32 service manual. Couldn't find what I was looking for.

My question is quite simple.

I have a R32GTR that is being stripped out, and I have located a number of ECU's installed in the boot & drivers side rear quarter panel (rear passenger panel.)

It would be nice if someone could please advise what these computers are used for

1. ECU Installed Rear drivers side

2. 2 x ECU's installed underneath rear parcel shelf.

I'm assuming I have an HICAS & an Altessa ECU. But what's the third for??

Another quick question, If my HICAS has been removed, so I need to keep the steering wheel sensor on the column? Or is it linked into the ALTESSA system also.

Thanks guys!!

Fuel pump related stuff

ALTESSA's are usually found on the back of shtbox Commodores.

HICAS on drivers side, amplifier for radio antenna in the middle, ATTESSA on the passengers side.

Another quick question, If my HICAS has been removed, so I need to keep the steering wheel sensor on the column? Or is it linked into the ALTESSA system also.

The sensor is not linked to the ATTESSA system - look at the schematic on p CH66 on the manual.

Yep. Fuel pump control module - its what brings the power feed to the pump down to 9V at idle, by switching in a soft earth (that is, an earth connection via a resistor).

I've had two fail on me, so i'm running a direct earth now.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
