Toyota Scion TC 2az MS1 Wheel Decoder

Post by alftuning »

Hi guys!
I'm working with a Scion TC 2006 with ms1 v3.0. Im sure the crank wheel is 36-2 but if i move the angle over 20 the car shut off. The car only start and runs only of 0 to 20 of angle. Any idea? Maybe a bad wheel decoder?

Trig pos A = 3
Trig Return pos A = 8
Trig pos B = 21
Trig Return pos B = 26

others = 0

To get a 60 degree trigger angle, subtract 2 from all the position values.

So, new values with 2 values subtracted
Trger pos A = 1
Trig return pos A = 6
Trig pos B = 19
Trig return pos B = 24

??? Thanks!

The final arbiter of whether your settings are right will be the timing light.
