Can anyone direct me or betteryet tell me what the factory specs for ignition timing in degrees be?

 

Doesnt anyone know?

 

20 lead 5 trailing ............checking

 

trailing side 20 atdc(-20btdc)

leading side 5 atdc(-5 btdc)

 

knock sensor(code 05) pressure sensor(code 13) can cause timing issues

 

ecu terminal 31 voltage should be around 5v with igition "on"

also check e/l p/s a/c crank angle, throttle sensors aswell

 

ow also 550-950 rpm ( 750 hold) is where you check the timeing

 

thanks its kinda going towards helping me diagnose a much bigger problem im having at the moment though i have no idea what it is

 

I just had my engine rebuilt and put back in, a rotary mechanic told me that you can't adjust timing on a 3rd gen-he said its more the way you put the rotors back in when you close the engine. Is this true? I seen facts on the timing and i know its not a piston engine-basicly i just rebuilt the engine, should I check the timing, and how?
My car is a 1992 fd3s RHD with a 1997 jdm engine-for other people to learn from my mistakes- Don't ever get a jdm engine with a "black box", newer version of "rats nest" because the harness isn't the same at all.

 

Nice 9 year bump!!

If that "mechanic" rebuilt your engine I would probably pull it apart and rebuild it again as per the FSM!

Ignition timing is changed by the ECU, NOT by clocking the rotors out of alignment...

 

Good to know, you could still have a stock ECU right. ****! Thanks for the info. Gonna go fix that.

 

I'm not sure if you're trying to be a smart *** here, or if you're being serious....

 

i'm being serious about the timing. I didn't know that. I am not trying to be a smart ***. you learn things everyday right

 

I see the idea what he meant but it's not done during the engine rebuilt. After the engine is put back it needs to be calibrated so that the timing predefined in the stock ECU would match the physical angle degrees on the shaft e.g. 10 deg ATDC (after top dead center) set in the ECU should not become a different value physically on the eccentric shaft. Calibration is performed with a timing light by taking into consideration the marks on the dampener for the TDC value. Also I think CAS (crank angle sensor) needs to be setup correctly too.

 

Ah, right on. It can be tough to read "tone of voice" when it's just typed up.

The biggest (problem) I can see with clocking the rotors out of alignment would be throwing off the balance of the rotating assembly. Adjusting timing is relatively simple and I'm fairly certain the ECU is regularly doing just that based off a variety of factors.

 

Thanks everyone though. My car is at a garage now, i will go see him soon. I hope he can figure it out, its not a piston engine! True fendamonky, sorry if it sounds "bad". i will look at the owners manual alittle more and learn about TDC etc... I dove it for a while like that and i hope i didn't screw anything up.

 

If I may suggest something, I would hop on the Canadian regional subforum and find a reputable shop to take your car to for work. I'm not familiar with who's who up there... but a bad/lazy mechanic can screw one of these engines up REGARDLESS of how much they charge you..

 

I just got my car back, it felt good to drive it
In Canada there's really only one guy-Derwin Tuning- It was him that told me that. Really nice guy, knows 7's inside out. That I find odd though, anyways. I sold my car and i am going to regret it I know I will. The guy is coming from the States on Monday. I will tell him to check that out. I didn't drive my car since before christmas and I drove it today and I felt so good. I am for sure going to go back to rotarys- I still have the weekend to drive the **** out of it though
