How to set the REF/SYN mode of Toyata 1NZ-FE engine

[Fueltank-Tai]

Dear All:

I am installing M4 pro to Totayo Echo 1NZ-FE engine 1500cc VVT. I found the REF 36-2 and SYN 4-1. I checked the serivce manual and Both sensors are Magnetic ( two wires) and fall .
I want to know how to setup the REF and Syn sensor. Thank you so much.

THis is Mode 28 in an M800 but not supported in M4. This engine has variable valve timing which is also not supported in M4. To make it run you would need to modify the cam trigger so it has 1 tooth and use the 2 missing teeth twice per cycle mode but this would leave you without VVT control. You would really be better off using an M400 with the Cam Control option for this engine.

Dear RossB:
How are you? Thank you for your reply soon. Could you teach me how to select one tooth from ( CAM Trigger 4-1) for use . Thank you so much.

You need to remove 2 of the teeth from the cam. The tooth you keep should be the one that occurs roughly 180 degrees (crank rotation) from where the missing teeth on the crank trigger pass the crank sensor. You will probably have a chouce of 2 teeth to keep, it doesn't matter which one from the two you choose.
