tce reluctor wheel kit...checking timing??

[merlot566jka]

how can i verify that its installed right? i want to check my base timing to see if i have it (it being the timing of the cps to the reluctor wheel) set right. can i use a timing light? im sure id have to make a pointer and mark the wheel some how. i know theres notches that are labled, but like i said, things changed on my install.

i just want to verify that '0' degrees is where my zero is. i know fieros are a little different and my brackets made for the need to trim the cps holder.

can it be done?

I don't think so... with our computers the delivered spark timing is constantly variable based on RPM, engine temp, intake air temp and other factors that would make using a timing light virtually impossible.

If it's running it's close enough...

Won't the ICM fire at 0* if it's disconnected from the ECU?

I believe so, i wanted to check that a while back but never got the chance.

how?

I know that you don't need the info right now but here it is for your next engine. Since the timing on a stock DIS system cannot be changed, GM did not put any timing marks on these engines.

To check timing you will need to do the following: (easier to do when building the engine)
1) Accurately find TDC for cylinder #1
2) Engrave timing marks on the dampener (allow for pointer location and belt routing)
3) Make a rigid pointer that points to the 0 timing mark
4) Disconnect the EST wire (IIRC) and check timing with engine running

When using the TCE external trigger, the timing should be within 1 degree of stock timing when it is set to 0. I had considered making some timing pointers but decided not to because of the many variables from vehicle to vehicle.

thats exactly what i thought!

thanks so much
