Hi all, does anyone know how many pulses crankshaft position sensor output for one crankshaft revolution.
I tried to find it in service manual and i'm pretty sure there isn't such thing in.

Depends on which ECU you have.

00 & 01 ECU's have one pulse per 360 degrees of crank rotation & the ignition sparks every 360 degrees

10 & 11 ECU's have one pulse per 360 degrees of crankshaft rotation & the ignition sparks every 720 degrees.

I am working on a mod right now, which will be able to advance the ignition timing by 4 degrees & will only cost a few $ to do.

Can you explain this a little bit. This sound like 2stroke engine. Is this ECU one from TDM that have 2 cylinder so every 360 degrees one of cylinder have spark or something else.
How can I identify my ECU. I have XTX year 2005.
Does ECU make spark as soon as pulse come (360 or 720) or it wait some time.

Interesting. Why do you want to do that. I think it will be pain to do that because of 1 pulse. Do you want to do this through hole rev range or just at high revs. Just High isn't it.
Do you know how pulser (sprocket or something) look like. If you know do you have picture of it. I thought about replacing this one that have 1 "tooth" with one that have 4 "tooth" if his only job is to pulse variable reluctance sensor (crankshaft sensor). Later it is easy to bring this pulses (4 of them) to the ECU through electronic counter/divider (by four) that will make one pulse every 4 pulses from sensor. ECU will not notice any change. Like this you can count time (degrees) from third pulse. It would be more accurate.

Do you know how pulser (sprocket or something) look like. Only from photo's If you know do you have picture of it Google Raptor 700 flywheel / stator & you will see what it looks like.

I know you can advance timing and use fuel with higher octane rating to get more power/torque.
I have seen moded toyota supra with high timing advance and 100++ octane rating fuel gained 60HP.

We already know by advancing the timing 3 degrees across the whole range give us more HP & Torque.

This is a dyno run proving the gain with 3 degrees advance. Blue line has 3 degree advanced.

Great, didn't know that.
Waiting for your mod.
