in a GTR the motec still needs the stock ECU to run the attessa system. So as long as your motec is away from the stock ECU and hidden somewhere...say under the passenger seat, then you shouldnt have a problem.

I have also spoken to a motec installer and he said the Motec is the only aftermarket ECU that can be tuned and passed under EPA and ADR's.

i dont see the problem with having an aftermarket ECU providing the Emmissions can be read and that your car passes the emmissions test.

RedR32: yes i have asked EPA directly permision if i tune the MoTeC to standard EPA standards. and i got a simple "no you cant". so i am not sure about keeping the MoTeC in.

By complying with all ADR's and emmissions laws, and having the correct test performed, you CAN have the Motec passed. That is exactly what a engineer does. they test the car to ensure that it complies with all aspects of road and emmissions law and then issues a certificate stating that fact. otherwise why the fu(k would you bother paying $XXX for an engineer.

I would be calling an Vic Roads authorised engineer and getting an unbiased opinion. not some epa peanut.

yeh i think that mite be a good idea, because i do not want to spend all of this money for no reason - i have spent enough as it is.

thanks for the advice.

Really? That's a new one, I haven't heard that before.

There's nothing on the VicRoads website that even hints at aftermarket ECU's being illegal.

According to the last enginner I spoke to they are illegal; To the best of my knowledge the reason is that they can be adjusted easily to make them "pass" epa style tests, and changed once you drive out the door. I think this is a case of vicroads illegal vs epa illegal which gets cloudy at times. A vented back into intake BOV will pass vicroads normally, but fail epa because its not factory. I'm not an engineer or vicroads or epa tester, so I can't tell you for certain.

Even if that was not true, the price for an approved emmisions testing is rediculous last time i checked, a simple engineers certificate for 500dollars normally doesn't cover the nessesary emmisions testing that I would imagine would be needed to approve an aftermarket ecu.

ive sent you a pm SIR-JD regarding a possible workaround for the ECU situation.

thanks for that slow_r31 - everyone i have spoken to have told me that the MoTeC is illegal fot the same reason you have said. and no engineer will touch my car unless it is totaly stock. this i do not understand - because people often get aftermarket parts engineered so they are legal on the road??

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
