May not be relevant, but the NA6 AFM, & I think the NA8 MAF, have a built in safety switch which cuts fuel if the NA6 ?/NA8 hotwire isn't registering air flow.

That's why I love this forum, i'm always learning new stuff.

see my 2nd & 3rd post on the following page:

that was my thinking, but my understanding is you're having the problem when you run oem ecu, emanage & MAF (not when running oem ecu, emanage & MAP). this suggests emanage deconflicts for the oem ecu when running MAP, but when trying to run emanage with MAF there's a conflict unless emanage is reconfigured, i.e. jumper/s or similar changed.

appreciate yours is a 1.8 & so uses a MAF - my suggestion was that the same or similar principle applies to the 1.8 as for the 1.6, even though 1.6 AFM wiring is 7 pin v 5 pin for 1.8 MAF. Seems academic now as it sounds like you have too much fuel & not fuel starvation. I 'don't know enough about the emanage to suggest a solution, but I'm sure there's someone around here that would. Maybe try searching 'emanage' on here & Google for a writeup?
