Update.... I changed the trigger polarity and the engine start with sequential setting but sound was upnormal untill i turn the knock setting off can anyone describe to me why does my knock setting was wrong so it pulls alot of timing at idle or what and what the right setting for the 1jz stock knock sensor Thanks in advance @Adamw @koracing

Okay i will change both of them

But the trigger 1 goes to +ve volt first not the -ve

Are you sure that the trigger 1 is incorrect too ?

No it came to me with old tune with this wiring

Here is the trigger scope @Adamw @koracing @essb00 Trigger Scope Log 2023-07-22 6;33;56 pm.llg

@Adamw @koracing

The password locked map works great with no issue ! Do you think if i try -155 trigger offset it can help @Adamw

@Adamw

Today the engine starts after i change the ignition setting to wasted spark but the engine sound was upnormal and alot of trigger error that doesn't happen with previous locked map I don't know why and the cam angle test show's that the cam is run between 664to667 and that's upnormal do you think that it can be wrong polarity for triggers wiring cause my trigger offset is set to 205 like normal the log i posted is for it after it start with wasted spark ignition and upnormal sound new omar jz.llg And this log from the password locked file kd jz log.llg

Yes i always start the old map that password locked to make sure that everything still works fine ... Okay i will take a log for the cranking today and post it

Vvti selenoid has two wires right one of them is wired to digital input 1 and the other one is wired to aux 3 thats what i mean and i think it won't start up cause the setting of the digital input but if it can start without the vvt selenoid so forget it and let's see what else can do that i see you mentioned that i do the injector setup wrong can this don't start it thanks in advance and sorry about my bad English cause its not my first language

Thanks adam for answer its 1jz stock block and head Audi R8 coils / id1000 injectors And not stock wiring harness The vvti sensor is wired to di1 and aux 3

It's 1jz vvti it came with password locked so i rest it go factory settings and starts from a base map and iam not who made the wiring for it so i checked the wiring and found that the vvt wired to digital input 1 and aux i tried every thing in the map and still no start just make a load pop's from the exhaust any help ... 1jz.pclr

I chasing a misfire the made me hates the car hope anyone can help Its 1.8T audi 20V engine big turbo setup Everything was working good 1.5bar boost 7k rpm with no problem untill i changed the throttle body by bigger one made modification to the intake manifold to be 2 sets of injectors and i put a kill switch at the main battery ground .... Then i found that misfire its only happens on load it rev free without load and it can go to 1 bar. 6800rpm with the misfire in second gear but in 3rd gear won't go more than 0.7bar and 4500rpm the misfire is very big I changed the coils/spark plugs/injectors trying lean/rich mixture and still misfiring compression test the 4 cylinders 180/185psi ... the only thing i found thats the volt drop to 12.6/13.2 at idle solid 13.9/14 Sorry for my bad English ss1.llg bsk.pclr
