Finally got around to playing with the cossie again.

I’m getting bad over fueling on idle and it’s really lumpy when reved. Plugs soot up within 30 secs of running.

it’s a 2 bar map sensor and im seeing 2.14v ignition on (book says 2.2 so that’s okay). At idle it’s around 1v and will increase when reved but erratic and jumpy. Book says should be 0.25 to 0.6v at idle. Could this difference of 0.4v cause my overfueling? I have literally changed everything else except the MAP sensor.

(I’ve test across ECU pin 11 (ground) and pin 15 (output voltage). Input voltage at 30 is 4.94v so that’s fine as should be 5v)

Cheers in advance
