VEMS Problem Help

[ian4455]

OK i've just been trying for the first time to get my car running on vems, I've now done something and now i have no spark. Has anyone got a complete config i can put in my vems ecu (420cc injectors) to get me started please ?

look in this thread, there are several config files that can be helpful

..my coils aren't firing ! Ignition output settings, my VEMS is a plug and play version for a aby.

when you say you've "done something". can you be more specific?

check spark output on all 5 cylinders. in particular, see if you get spark from the #3 cylinder. it is fired differently than 1,2,4, and 5 on the PnP setups (stepper driven, vs TTL ignition output drive).

There's no spark at all, I removed coil no1 to see. I uploaded the wrong config to the ECU.

go back to your 3b config. The only thing that will be different is the ignition outputs page. If you wired it the same as the vems PnP for AAN, your ignition outputs will be, from top to bottom:

Stepper D
IGN 4
Stepper A
Stepper B
Stepper C

My coils no 1 and 5 are broken, swapping them over with others they fire ok so its not the ecu or wiring. Guess i'll have to wait for some replacements...

That is good bad news! A least you know what is wrong.
