alright to all that were helping and following the car is now running, driving etc.
The issues with my wiring that were intermittent were due to a few factors.
1: the biiigggg one was that my 1uz was out of a crown that seems to have no wiring diagrams for it on the net. So for a carton I was given the correct pin out for the ecu and within a few mins of joining wire to the correct place the car was running and all good.
2: when I started have these issues i thought it was a the ecu or igniters. but after swapping them with borrowed ones i discovered that mine seem to be ok it was just the way that last plug on the ecu was wired.
3: The engine is not wired 100% as per recommended... but thats all things that can be changed.. but having said that it runs fine and makes good power. for a start m-rel isnt used, i know that apparently the ecu wont know whats happening but it seems fine...
Now i have further questions if anyone can out of good will comment on.... the speed wire on the ecu is to be connected to the dash speedo. but my car uses a mechanical speedo... so it wont have anywhere to connect to right?
The final thing is that engine runs smooth some times then will idle rough. initially i had a spark plug wire to one bank that was rooted. so i replaced them all and that seemed to fix the issue but its back. while i had the wires out i changed the ecu temp sensor just to make sure that it was all good.. still same issue also sometimes the engine idles extremely low.. like under 500rpm..
I used a 4 cylinder hilux tacho, it just seems all a bit low on the rpm side. like it climbs when driving but when its coasting at 80kmp/h it sits at like ~1200 rpm...>>? is that even possible.?? ive got 32's tyres and diffs are 4.5s. running the 1uz auto box.
overall the car is great and I cant really complain. im just trying to make it all perfect.
Thanks to all the guys that have helped and commented so far. I appreciate it. After all thats the purpose of a forum - to share knowledge. If anyone has any questions to ask me about my build ill be happy to share what i used or how it was done after all its all been done at home. This was my first conversion and its had its headaches but ive only done it as a part time project and when i had spare time. Thanks
