kubus1 Posted April 18, 2003 Share Posted April 18, 2003 Your help needed again. I was going to fit my TRL VFCC today. I looked into the ECU and the diagram provided by TRL doesn't match up with my car. I take it that TRL diagram is for the 2JZ-GTE and my ECU is 2JZ-GT. Dont really know what the difference is but all I know is that the connections on the harness have all different numbers. Does any one have the diagram for my engine ECU? I guess it may be one of the differences between the European and the UK car. Hope you can help. Cuba Quote Link to comment Share on other sites More sharing options...
THOR Racing Posted April 18, 2003 Share Posted April 18, 2003 ummmmmmmmmmmmmm........... the 2JZ GT is the normally aspirated Supra and NOT the Turbo one which is the 2JZ GTE. Hence you DON'T NEED a VFCC fuel cut. As you don't have any turbos...... Have I missed something here? What is the exact model and year of your Supra? You may be confusing the writing on the ECU with the model of car you have or you might even have the VVTi. I have all diagrams but little point until you say which exact model it is. Oh.... and I was only a phone call away Don't hesitate to ring if you have problems. Regards Pete Quote Link to comment Share on other sites More sharing options...
Thorin Posted April 18, 2003 Share Posted April 18, 2003 I thought the NA was "2JZ GE" and the turbo "2JZ GTE" the T indicating turbo? Quote Link to comment Share on other sites More sharing options...
Guest Martin F Posted April 18, 2003 Share Posted April 18, 2003 Originally posted by Thorin I thought the NA was "2JZ GE" and the turbo "2JZ GTE" the T indicating turbo? Yep that's right. Cuba i would have thought yours was exactly the same as a US spec car which is more or less the same as a UK spec car. Do Petes diagrams for the UK spec car not match up ? You were looking at the main ECU (biggest one) not the TRAC ecu weren't you ? Quote Link to comment Share on other sites More sharing options...
THOR Racing Posted April 18, 2003 Share Posted April 18, 2003 Doh!. Oh yeah. Mixed up me numbers.... anyway... the ECU is under the passener carpet against the bulk head. Sort of where the soles of your feet would be when you sat inside. Regards Pete Quote Link to comment Share on other sites More sharing options...
kubus1 Posted April 18, 2003 Author Share Posted April 18, 2003 I was surley looking at the right one. I followed the instructions from the mkiv.com. It doesnt match up at all. It says exactly that on the ECU: 2JZ-GT A/T ENGINE CONTROL TOYOTA 89661-14538 What do you reckon Pete? Cuba Quote Link to comment Share on other sites More sharing options...
THOR Racing Posted April 19, 2003 Share Posted April 19, 2003 You still haven't said what year your car is? Could be the VVTi see below. Pete Quote Link to comment Share on other sites More sharing options...
kubus1 Posted April 20, 2003 Author Share Posted April 20, 2003 silly me!! I thought I mentioned that. The car is 1994 Twin Turbo Automatic Typical European Spec VIN Number is: JT164JA8000012370 The main difference in the ECU, in my opinion is that on your diagram it shows the numbers 1-40, 1-70 etc I only get 1-40 on each plug. I dont know if you get what I m trying to say. If I remember right, I should cut a blue wire which is in position 67 or somthing like that. The only alll blue wire I have is in the middle plug on position I think 8. I ll try to take some pics of the connectors when i get the chance. Or maybe you could mail me all of your diagrams for a Supra and then i ll be able to work out which one looks like mine. Would that work? Anyway, Thank you for your help. Happy Easter Cuba Quote Link to comment Share on other sites More sharing options...
THOR Racing Posted April 20, 2003 Share Posted April 20, 2003 Ah.. Sorry. No you've tried to make it more complicated than it actually is. IF the ECU LOOKS the same layout. i.e. one large connector and one smaller one to it's right. JUST FOLLOW the PINOUT and forget numbers and colours. The number will not match and the colours are the colours of MY VFCC NOT the ECU wires. JUST use the physical location of the PINS designated on the diagram and don't worry about anything else. I hope that solves the problem. It really is simple. I guess if you're not used to this kind of installation then it can appear to be more complicated as you're more likely to check every little detail Good luck. Ring me if you have problems.

kubus1 Posted April 20, 2003 Author Share Posted April 20, 2003 Thanks Pete, I will give it another shot. I just got really confused whem the colours did not match as well as the numbers. I will go with your info then. I know its know difficult but I m doing it first time and thought that if I cut the wrong wires I'd be in trouble. Thanks again. I ll let you know how I got on!

THOR Racing Posted April 20, 2003 Share Posted April 20, 2003 Toyota numbered the connector diagram but I guess some other manufacturer (Like Tyco or AMP) made the connector. Hence the wrong/different markings. Remember to SPLICE the power and ground (i.e. just JOIN the wires) and ONLY CUT the MAP signal wire.
