Hey everyone. First off, if I am posting in the wrong section, MOD please pardon my mistake and put this where it needs to be.
Last year the engine failed in my 03 GT so I decided it was a good idea to upgrade and install a 2zz w/ 6spd trans. About a year later, the swap is finally almost complete. :/ Some people may recall a few of my previous posts about troubleshooting, and thanks to all the help back then I wanted to reach out for advice again.
Basically I am having trouble achieving Lift. What I am experiencing is when I hit over 6000 RPM the engine bogs down and instead of engaging lift, begins to under perform and lose power. I suspect it has something to do with the oil pressure sensor not properly sending the information to the engine to engage, however I have replaced the physical sensor and still no change, but I am honestly not entirely confident I replaced the right sensor at this point.
I have also tested using two different ECUs with no change to rule out a bad computer. To add to that, almost all of the issues I had with the swap were tied to the electrical wiring. I have had to run new wires, splice into wiring, its been a mess. Because of this I highly suspect it all comes back to the wiring. I thought I would reach out to someone who has insight or experience (with either Lift, engine swaps or electrical) and can possibly point me in the right direction on what would be best to test next and start ruling out possible causes. It would really be a shame to go all this way and not try to get Lift working.
While I tried searching the threads for helpful information, I did come across a thread from farhanali89 about a Lift troubleshooting guide, but could not find the link anywhere. If anybody knows where this guide went I would be more than happy to start there. Otherwise, any other advice would be greatly appreciated.
Thanks in advance,
