Me and a friend bought ms1 and ms2 ecu's as we wanted to go efi. We are trying to map the cars, well trying to get a decent idle for mot. My friends car is up and running so we are having a go. We cant get the car to idle correct unless we take all of the fuel out of the bins (all this is obviously being done over 70 deg C ) We have dropped the bins down to as low as 4 and the timing is set to 12 deg. If we raise the bins to 10 we are getting a lot of black smoke and lumpy running which is telling us it is rich.

At best we can only get 10.5 AFR which is way to rich for idle. We have read several manuals such as extra efi and mega manuals but what ever we try it isn't helping. I don't know if it makes a difference but a brief spec is below:

2.1 zetec turbo
480 cc H/I injectors
MS 1
21 psi map sensor

Cheers for the help.
