The MAF unit replaces the stock AFM - It used to be sold by Pro-M but the company has changed it's name and site; maybe Martin has the link stored? Works with the stock ECU.

Thanks for the graph Martin, maybe I'll try that later today. Still have some more tweeking work to do of course.

Innovate has suggested afr ratio's for street-driven 4 stroke motors:
14.6 : 1 is dangerlously lean under power
14.2 : 1 is lean, max power
13.5 : 1 is max power (suggested for blown motors?) the range I've targeted
13.2 : 1 too rich for un-blown motors
