No7Yet

Take a quick look at a stock FC pulley and let us know where the yellow mark is.

Actually, I spoke at fair length with Jon this morning, Steve, and he agrees with both of us. I do appreciate the input, however, and feel that any honest discussion is valuable.

Here's what I'm hearing from both sides.

If set the way Microtech describes in the manual, the timing is set correctly, and is the most simple way to set the timing. However for those who like having everything set to zero and read the same then remarking the pulley is the way to go.

Does that sound right?

It sounds right but if you read what you just posted I think you would answer your own question and what was being said originally by A-spec, and that is if you want everything at true Zero then you mark the pully.

I really am having a hard time understanding why you came on this thread other than to ARGUE what was posted. The original post was made clear if you want to be truly zero'd mark the pully.Then you basically come on and say don't bother with that nonsense, you got two guys with worlds more experience saying they mark the pully, and you say nah it's nonsense, it is nice though that you appreciate their opinion on a thread they started to clear things up. All it seems like to me is you just made it all the more confusing for those who don't know to show how much you do.

I agree

While it is more difficult for people to remark the pulley I think it is ultimately the right way to do it. Now with that said no7yet does have a point, and if someone can verify what the static timing is on the factory base map, then it would be a little more concrete.

Ok here's the deal.........................
The static timing on a 13BT base map is usually set at zero.If you lock the timing & set it to the first mark (yellow) the timing will be zero'd at 5 deg atdc.This is done like this by Microtech so everyone will set their base timing 5 deg retarded & hopefully not have a blown up engine due to too much ignition advance.Think of it as a 5 degree safety margin from the factory.
As all of you know by now this isn't a true zero mark which is why I prefer to re mark the pulley with a true zero mark & lock it there.However,you need to be on the ball with your tuning & know EXACTLY what you are doing.
To end up with the same result using the static option,lock the timing & adjust the crank angle sensor so the yellow mark is lined up with the pointer,then put +5deg in static.The ecu will then add 5 deg overall in all your timing values.So as you know,the timing was locked at 5 deg atdc but with the 5 deg static value it is now at TDC,and all the timing values in all the screens will be correct.
After reading this most of you guys will be scratching your head trying to follow what the hell I'm talking about......................
This is why I re mark the pulley & lock the timing at true zero & have nothing in static.
Saves a shitload of confusion!!!!!!!!!!!!!!!!!!!!!
