timing issues and questions

[teebone]

If the cam position sensor is off by 1 tooth, how much will the timing be off?
Will the car still run?
I had the engine rebuilt and tryied to time the engine but I could only get 5 degrees btdc before I ran out of adjustability. BTW I have 89 turbo.

It will run pretty poorly. I would make sure it timing is all set correctly.

The car is running, not missing or sputtering, but my adjustability range is about 5 btdc to 5 atdc

Sounds like you are a tooth off like you thought. Moving it a tooth should get you where you need to be.

It should look like this:




Make sure the crank dampner is pointing at "zero" and both cam gears are aligned to the top index marks on the back plate.

I dont get it! I moved one tooth and now the timing is over 20 btdc.
Anyone know why I can only get 5 btdc on what I believe is the correct tooth on the cam sensor?

On a side note when I jumped e1 to t1 in the diag. port the computer had a code 24 but I think the code is related to my MAFT Pro

Going to revive this thread from the dead because I'm having the same problem!

Looks like it's still unresolved

I cannot get my timing adjusted to 10* BTDC, I'm also running Maft Pro (without timing control or monitor) and when the car is jumpered and warm, I max out the adjustment in either direction and either I can't get it high enough, or I move it back one tooth, and I can't get the timing low enough!!

It's like my CPS needs to be right in between the two teeth!

Could this be because my head and block have been shaved too many times? Or could it be a CPS out of adjustment?

did any of you guys figure this out? I got close 12 degrees only and I cant retard it anymore. I pulled the cps 3 times with the picture above. It was sitting at 29 degrees before top dead center before.

I had to turn my CPS 180*

I had the crank at TDC, but i was on the wrong compression stroke

Make sure you're at TDC and both cam gears are pointing up!

make sure you have the diagnostic T1 and TE1 bridged while you set the timing
