When using a 12-1 set up each tooth is 360/12 = 30 dgr.

The secret is, not to make it complex.

will read that... thx

When using a 12-1 set up each tooth is 360/12 = 30 dgr.

then there is something I don't really understand... I'm considering that the trigger wheel has 12 theet + 12 slots, therefore 360/24=15 deg. Or one tooth includes the tooth and the slot?

Considering this sentence from the link sent:

Trigger Angle Example: Begin with the crank positioned at TDC of cylinder #1. Rotate the crank in running direction until the missing tooth passes the sensor, and the first tooth after the gap is under the sensor. Stop. How many degrees did the crank turn? That is your *approximate* Trigger Angle. Enter that number of degrees in TunerStudio. When the engine is cranked or started, use a timing light to verify exact Trigger Angle. Viewing internal wheels through the sensor mount if often effective.

And looking at the picture, then I think the angle should be 0 deg. (or 360 deg, that I guess is also 0 deg.)

Also depends on having set the leading, or trailing edge of the tooth.. However, as long as you understand the principal, then when you come to firing up, you can change it.

yep, something like that.
It only counts the front or backside from the tooth, depends on your setting, trailing or falling edge.

It sounds like it should be really simple but my brain just switches off when I start to work it out, your first tooth is 90 degrees from TDC but your sensor is also 90 degrees from TDC, so your first tooth is at 0 or if your trying to work our the centre of the first tooth is in not 7.5 degrees? (180 degrees divided by 12 teeth = 15 degrees. half of that is 7.5)

also stock settings are 6 degrees BTDC so is that something to take into account?

Well, I can start trying with:

CKP: OEM hall, hacked trigger wheel converted to 12-1, will try first with 0 degrees respect TDC
TPS: adapted from a keihin carb, 3D printed parts to adapt it to the ITB set. Will "scan" the signal and TS will get the min nd max.
CTS: will us ethe OEM sensor, need to introduce these parameters

IAT: will use a chinese copy of a delphi P/N 25036751, need to characterize it...
MAP sensor: I have two units to choose from, one bosch 0261230188, the other a GM 96330547, will us ethe last one since I also have the connector.
WB O2: don't have any yet. Will try to substitute with the potentiometer

According the picture, I will use 0deg to start with. I will assume leading edge, (I think you can choose leading or trailing)
