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 http://fc3spro.com/ |
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... |

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.

mine is 1-2-3 and running!!! an other 20B fired up! it sound cool!...
there are somes f**k with the ECU ... .. it will be fine! Jesus's RX-7 |

[snapback]742936[/snapback] [/quote] I think the loading on the eccentric shaft is "better" with the 132 firing order. I think the harmonics is also not as bad. -Ted http://fc3spro.com/ |
3 20B's and all have the 1-2-3 firing order based on rotor position.
Anyone out there with a 1-3-2 20B? Anyone have any solid info on this firing order deal? JD |
Roger Mandeville said 1-2-3, but you could run it 1-3-2. That threw me for a loop so I stopped asking questions :p
