What is the best output to use for Check Engine Light? (MS3X

[Danbob]

Hi, I'm almost finished making my harness to install my MS3X.

I want to use an output to light the OEM check engine light (ground to light). What is the best output to use for this?

I have MS3X board, with knock module installed. most outputs are unused.

I was going to use FIDLE, can this output be programmed to output CEL?
Is it better to keep FIDLE for something like water injection and use a lower current output for check engine lamp?

Thanks
Dan

Any of the outputs that are selectable for CEL duties are the best ones to use.

FIDLE isn't a particularly high current output. It will work fine here.

Ok thanks.
That's one more down then, only vss, external air temp and a couple of others to figure out now

Cheers
