There should be a 2 pin pigtail somewhere along the firewall with a single pin inside it. When you ground the pin it puts the ecu in diagnostics mode and sets ignition timing to base timing. If you leave the pin grounded the ecu will always run base timing no matter what. I'd say do that and set it at 10 degrees for now.
so if i went to an safe with 450cc injectors I'm still going to be running lean? can i convert this 64 to a 63 ecu?my friend has a parts car 93 gsx.. no motor but it may have ecu and harness
wiring is no issue.. but converting my motor to coil packs is all I'm worried about
10 degrees retarded?
set it to 10 degrees advanced if you ground that pin out and leave it grounded.
If you switch to the 63t ecu and harness, then all you have to worry about is wiring your distribtor into it as a cam sensor. Coils and power transistor will be plug and play on that harness. Now im not sure if the distributor will have the same type of signal as the 63t's cam. I've looked into the swap but haven't figured that issue out yet. I have the distributor pinout and know it sends a signal for top dead center as well as cam angle.
ill have to do more research on it. id love it to just run normal
I just checked the pinout for a 1g dsm and it lists crank angle and top dead center. So it is possible to wire everything up. Its just a matter if the signals are compatible or not. The cam sensor is a hall effect type on the dsm. I haven't been able to find out what type our distributor is.
Did a quick search to see how a hall effect sensor works, it uses a magnet. The sensor inside our distributor doesn't use magnets...It just uses a wheel with cutouts in it. So it doesn't look very promising that it would work if you tried to do that swap.
Any clue what color the plug is? I'm seeing a white and brown with single wires.
And a blue with 3 wires
The ECU, harness, and main relay on the G64 is different than the G63.
The cam/ccrank sensor in the distributor is the same trigger wheel and sensor as the 1g.
Ergo, pull the harness, relay, coil packs, injectors, throttle body, and everything else that isn't the same from the G63 and stick it on the G64. You'll only have to worry about getting the TB to mate up.
Thanks for all the help guys
I think I'm just going to take the kit off and sell and make my truck stock again
