2G Timing

[godschylde777]

So I have a 6 bolt swap. I have a blacktop so the signal is inverted. I also swapped the wires at the ecm. When I replaced the cas, i put all of the marks on point. So here is my question. If I set TDC to factory #1 cylinder. Yet because I swapped wires, is it still #1? Which call do I use to set base timing?

Lets start over

What ecu is it
What cam angle sensor is in the head

It all depends on what ecu you are running. It is also programmable in the ecu to invert the signal so you dont have to cut wires

If it is a 97+ cam angle sensor with a 95 eprom ecu with dsm link both 4 and 1 come off of the second coil.

You would need to go into link and select invert cam sensor

Hello, thanks for the response. It's an ecmlink v3. A blacktop cam angle sensor. And yes I've inverted the signal and I've swapped wires. She starts just fine. I just don't know which coil to put the timing light on. Do I use the new number one coil or the original number one. Or is it still number one because it is now a true number one..... Lol. Confusing

Use cyl #1.

If the timing light is adjustable, puta dab of whiteout on the timing marks on the cam geras, set the gun to 5* BTDC and point it at the cam gears. Makes it easier to see the light.

So cylinder one is cylinder one I take. Cam gears or crank pulley?

 

[renovatdkitchen]

Yes. The one closest to the timing belt. And use the cam gears to set it only if the gun is adjustable. If not then you have to go by the crank pulley.

Do you have adjustable cam gears, that is the only reason you would need to set and check timing with a timing light on the harmonic balancer and engine cover.

Black top is not a term used with the dsm's. There is a black box ecu that came on 98-99 cars which had a cam sensor placed on the passengers side of the valve cover. The 95/96 cars had the cam sensor behind the cam gears. If you had dsm link then you have a 95/96 ecu that needs to see an inverted cam signal to read the different cam sensor

It is adjustable

I have a 6bolt head. And I have heard it reffered to as a black top. But yes I have inverted the signal.

Oh and yes the cam gears are adjustable

@chrysler kid I believe he’s referring to the optical CAS.

Yes

K, Hard to help diagnose when no one mentions the car or the motor in the car.

Sorry . It is a 6bolt, and I was using a black-top. However I have since installed a 2g. Which now I need to see if the white mark on the reluctor.
