Hey Guys, I'm Making some Fuel Pump ECU replacements. It works with the standard Engine ECU and should be a direct replacement for the factory FPC. I have tested it with a UZZ31 ECU. It has the OEM connector, and is rated for at 20A. Version 1.0 is just On or Off, no two speed pump control...

I'm looking for someone to repair / Service my UZZ31 Soarer ECU. I'm in Sydney (ish). Would be good to have a list of places that can do them properly. What experiences have you guys had with ECU repair places? Who uses the correct spec caps and who will just use Jaycar Caps? Cheers

Just few questions about the link plug-in TS2JZX ECUs Has anyone used one? First up, will it run a 1UZ? The specs suggest it will with anything up to COP and full Sequential injection. Does the Link TS2JZX Plug in fit a Soarer/SC400 ecu case? Is there much repinning the ECU plugs needed to make...

On a 92 Soarer, Do the cat temp sensors do anything to the ECU? ( I have an Aus import UZZ31, I didnt think to get too much info before i scrapped the half cut) On my loom can see they go to the check connector CC0 and CC2 pins, and i assume the dash. ( its been a while since i attacked my...

Hi guys, Couple of questions about ecu wiring for a manual conversion. Its a 92 SC400 motor in a LH torana. 1. Is the Neutral start switch needed? Will the engine start ok with it removed? 2. Does the ecu need a gear signal (L or D) to drive properly. 3. Is STP required? Does it do anything for...

couple of quick pluming questions. where does the hose on the front of the plenum, (above the idle solinoid) go to? where does the little water hose from the pump/thermostat housing go to? where do the hoses on the charcole canister go? Thanks guys.

Heres a tricky one. i have wired the tacho output from the igniter to a vs commodore tacho. It works, kind of. the needle moves, but i think it is expecting 3 pulse per revolution. what signal does the 1uz igniter put out? I would think 2/rev? The ic in the tacho is a ITT 3003-393, but i...

Hi guys, Ive started wiring the 1u into my torana, using the uzz31 loom, fuse boxes, etc. I think i bit off a bit more than i can chew. I tryed chewing like hell, not working. The only thing i want to keep, apart from the ecu, is the cruise control. if possible. I have the wiring diagrames...
