well, its basic, but put simply, a piggy-back unit that links inbetween the crank sensor and ecu for timing reference/adjustability/retard, also piggy-backed into throttle position to switch it on/off at idle/low speed, and hooked into idle control valve for extra air/fuel at idle. a bit basic atm, but im currently developing it on my saab so will keep posted on how it goes. if all goes well, then who knows, may well start making up kits. il also test it on my zetec too. just wanted to get a feel for possible demand and any thoughts on the matter. cant see much point in paying out hundreds for als equiped management if i can develop my own unit, especially when the existing ecu has virtually every other concievable gadget except als. so any thoughts/comments are greatly appreciated. especially if anyones tried something like this before???
