Aite people i getting rel problems with meh mx6. The thing park up for about a year and a half! I fed up. I does see real mx6 on the road and i sure plenty of them is tuners who know what dey doing so help meh nah please....
Here is the low down, it will be kinda long eh....
My car was running a KFZE with a 5fwd box, appropriate ecu and all. The engine was smoking and back pressuring (aye i buy it so eh!) so i had to change it. I got a Millenia KLZE and installed it. Yes a Millenia klze, not DE but ZE. (To the people who want to tell meh the Millenia doh have no ZE, I did my research and the mill ZE has the same head codes as the jspec ZE however with a couple extra letters at the end of the code. The ones with the exact head codes as the jspec are the DE and i was able to see this difference on two millenia engines that were side by side but i digress...)
Installation details...
The KFZE brain and harness was used on the KLZE (The brain has to be chipped for the KL injectors and VRIS to work right).
Therefore the KF distributor (4pin) and VAF was used on the KLZE engine in order to work with the harness.
The other thing i changed was the flange with the coolant temperature sensors. This was necessary because the KF had 2 fan switches together with the signal sensor (tach) while the KL had only one fan switch together with the signal sensor.
Sooo after all that the engine start in one bounce but i really didn't rev to see if there where any probs at the time cause it was a miracle to me that it even start and idle...
Now the locations of the sensors were all different on the Kl as opposed to the KF so now the harness was literally stretching out all over the engine and wires looking like they want to burst out from the connectors. Therefore some extending was in order.
Now for anyone who has worked on the mx harness knows that the temperature sensors are on a separate harness from the main harness. This separate harness consists of the two coolant temp sensors, temp signal/ sending unit and VRIS 1 and 2. Now you see where this going....I extended this and none of these sensors working (I not sure if they were working before). No i not retarded!. I join and matched the correct wires and I tested continuity from one side to where it join on the other. I even had an electrician check just to make sure i eh going stupid.
Now the actual problem or problems....
Soo when the car starts now it misses and backfires until it warm up (coolant temp sensor). No reading on the temp gauge (temp sending unit) and when i rev the Vris solenoids not opening (VRIS 1 and 2). So now of course to make things worse the radiator fan not coming on at all so it overheating. An electrician showed me that if i ground the signal wire to the chassis the temp gauge shud shoot up. That not working. I tried it on a KF cronos and it work so he eh talking shite. He told me it mite be a ground problem. So i grabbed my haynes guides and check all the grounding points and everything seems to be in order. I even split the harness and traced the individual wires of the problem harness back to the grounding points and the ecu. In a desperate attempt i tried the brain from another car just to confirm if it mite be the brain and of course it wasn't. To make things a lil worse a couple of the wires on the Haynes guide are different colours form the actual wires on my car. I even checked all relays and fuses and had my normal electrician double check all of them.
In my attempt for PAID help....
I not calling any names i went by an electrician in Couva side, tell him the problem, he charge meh a 300, I wreck the car back home then same problem. I call a very well known electrician from Montrose and like i get sheit up on the phone before i even get to tell the person what the problem was or actually what i even call for and i eh even say nothing wrong eh. It hard to deal with them kinda people....
Beg for help....
I lost. I really need some advice here. I sure this cud be some real simple stupid thing I overlooking but I just not seeing it. I sure people do this conversion before cause these millenia engines actually selling in the bamboo and i saw it in other places as well. So please if any body had run into this prob leh me know the fix nah. Any kinda advice grateful or if you cud even point meh to an electrician who does wire car and cud actually talk to people in sociable manner lemmeh know nah...
