here I still have the connection diagram
and scope

Hello peter
Wenn ich mich nicht irre,hat der z20let motor vr kw sensor und nicht wie in deinen Primary trigger einstellungen zu sehen hall/optical sensor,und der first trigger tooth sollte nr 9 sein,trigger angle dann 60 grad(prüfen mit lampe),bei meinem c20let ist so,und er läuft.Die beiden motoren sind sich ja änlich

If I am not mistaken the z20let engine has vr crank sensor and not hall/optical as marked in your primary trigger settings,and the first trigger tooth should be nr.9 ,and then the trigger angle 60 degrees
(check with timing light),by my c20let engine it's so and it works because the engine are similar

regards Teo

Hello! My motor has a 3-pole sensor I have already switched to trigger 60/9 Perhaps you know the injector phase?

[astra vxr]

fire 2 banks of injectors at a time and see if that helps fire 1&4 and 2&3 and see what that does but its always number 4 thats getting the most fuel

i take it the setttings i sent you dont help ??

Have tried to verãndern but the engine Always runs the same My problem is that the lambda value is not going down when I go from the gas

Hello
Yes, both sensors are 3-pole, for hall sensor you need 5 or 12v, for the vr sensor only ground, if the sensor is original from the z20let engine, then it is vr (magnetic) and uses only sensor ground
My injector phase are: inject.1-ign.event 2/inject.2-ign.event 1/inject.3-ign.event 3/inject4-ign.event 4,and ignition outputs are the same as yours 4-2-1-3.
By me the injectors work when the pistons are aprox 20 degrees BBDC and the intake camshaft is fully open, but if you want that the injectors work when the inlet camshaft opens the valve, aprox 20 degrese BTDC,then you must have the following sequence,by ignition outputs 4-2-1-3:inject.1-ign.event 1/inject.2-ign.event 4/inject.3-ign.event 2/inject.4-ign.event 3

if its still the same on 4 with injectors changed etc just wire up injector 5 and try that in place of 4 and see what that does then that will rule out injector 4 completely

hy
have tried the new setting
the engine is operating normally at the booth when I go and give Starck gas he goes super
then below 2000 rpm it only runs on three cylinders
after some time again on all four cylinders

[peter1002]

have the spark plugs removed, there are the four black

[astra vxr]

so when its running its fine but when you put your foot down and then let off its goes pig rich then runs on 3 ? does it clear itself after a few mins if left alone ?

carnt look at log on phone

z20 c20 lets and c20xe have vr sensors and the 8v 20ne engines the x20xev ecotec engines have a hall sensor

hello
have the problem found
turbo damage Oil in the intake
