i need to know the correct secance



grank angle tooth for ignition and injection



and is the OMP pinout the same as an FD ( 3 of the 4 grounds to the ECU are the same color as the FD... i suposed that it is the same and the omp buzz ( 17 to 21 % opening)





thx in advance and sorry for my bad english

Our 20B firing order is 1 - 2 - 3.

I've *heard* there are 20B's with firing orders of 1 - 3 - 2, but I've never seen it in person.

Until I hear of first-hand experience, I think it's safe to say all 20B's are 1 - 2 - 3?

Ted, my modded dizzy was 1-3-2-1-3-2 with an event every 60° of eccentric rotation. It's not your average firing order. The original firing order of my engine is 1-2-3 as shown by rotor position while cranking by hand.

you mean that the secance is 1-2-3 with 120° separate them? exact 1/3 1/3 1/3 balanced?



and for the metering pump stepper pinout?



sry for my bad english...

I'm curious also.

An advantage? If your eccentric shaft was machined for the 1-3-2 firing order, then yes it is advantageous to run it that way. Mine is 1-2-3, batch number 756. It's an early engine, never opened, so I'm running it NA.
