Hey Patrick, sounds like you also have the Haltech Elite ECU Thank you for your help! I just dont want to clip off the wrong connector so just to be 100% certain, I would like to choose pin A23/DPO3. Can you point out which vsv it is in the diagram above please?
Great, thanks. Yeah I had been running the Haltech with stock twins/bpu with 272's for about 500kms then noticed I was getting knock regardless of the AFR's looking normal. Going single over next winter so the car will sit and slowly be dismantled awaiting new fuel system and turbo kit. Leaning towards FSR kit.
Patrick just to be sure, 1. am I going to use the plug from the lime green vsv in picture above?
2. Does it matter which wires from MAC go into the plug? I hate wiring...
Honestly I’ve never used the factory plug (I run my own two wires) but based on the diagram you sent I believe you are correct about using the lime green (VSV for wastegate valve). Polarity doesn’t matter on the solenoid as long as one wire gets switch 12v and the other gets signal to ECU (in your case DPO3). I would take a voltmeter and test for continuity between DPO3 at the Haltech connector and that plug for the wastegate VSV and go from there.
For a circumstance like this I would run a two-wire loom through the factory firewall boot with the engine harness but when I'm doing this I'm also wiring in other sensors like fuel and oil pressure, IAT, etc. If you want to utilize the factory harness I think you are on the right track. Just find out if DPO3 on ECU connector has continuity to that wastegate VSV.
I'm having trouble removing the banjo bolt on the fuel pump assembly. Tried everything I could think of besides an impact wrench. Wanted to ask some folks if that was a good idea or not? I'd really appreciate any insight you can offer.
To be clear and avoid miscommunication I found...
I have some shifting problems on this supra with a 2jzgte and a automatic box attach, as my knowledge is limited on automatic as i have worked most on manual cars, i really need som help, i have taken a video of the problems, there is no error codes stored on the ecu.. i have heard that the...
He, I have an issue with my supra mk4, The steering doesn’t response in same time, i mean when i turn right or left I don’t get response immediately. I have to take half turn then the car will turn. What can i do instead of buying a new steering box!
I removed my broken harmonic balancer, which was really a bitch to get off.
I noticed some small rust and other rough patches on the crankshaft (especially around the key) where the balancer sat.
The timing gear is even worse. Ruined my pulling tool half way, so I now first have to...
