I am installing VEMS V 3.5 fw: 1.0.73 on a Toyota Celica 3sgte.
Everything is fine, except some trigger errors.
We have used the 24 tooth OEM trigger wheel where we have removed 2 teeths, so we are going 12-1.
The car starts and runs perfect up to 4200rpms.
When we reach 4200 rpms the car strumbles and backfires.
Here is our trigger config:
Tooths on wheel: 11
Degress before TDC 50
Trigger tooth: 1
Next Trigger 6
And of course Whelldecoder on.
Whe have tryed to:
Switch the two wires.
Larger and smaller gap between the sensor and wheel.
Removed the 10.3 K ohm pullup resistor on the board.
Used a new shielded cable between sensor and vems.
Tryed to add a 800 ohm resisor on signal wire and ground.
But nothing helps.
Here are a scope log when the problem acting:
I Think it looks ok!
And the MSQ file
We took a scope log of the ignion setup also ( OEM Igniter ):
Thanks for your time!
IMO you have to enable N-1 in primary trigger settings! Filtering is questionable. MembersPage/GintsK
I have tryed to enable N-1, but whit no luck.. It dosnt help. I think we would try whit a good known distributor
I found my old working msq from 12-1 on 1.0.73final. N-1 is enabled, and angular width of tooth is 12 and missing toth is 24 in my config. MembersPage/GintsK
I will for sure try it in the weekend.. But I have 4 other cars runing whit the other config, and i think i allready tryed the suggested settings... Regards Daniel
