[QUOTE="nan83, post: 1063391952, member: 6718"] huummm... you need to search if got a device that can control stepper motor tb independently.. i oso donno about it... the cheapest way is to convert it to cable throttlebody...[COLOR=Silver] [SIZE=1]---------- Post added at 08:52 AM ---------- 6 hour anti-bump limit - Previous post was at 08:44 AM ----------[/SIZE] [/COLOR] s500 cannot drive coil... the ecu will burn.. CDI like dynatech arc can act like ignitor. s500-->arc-->racetech (but need 2unit, arc only 2ch) maybe not all CDI unit can run without ignitor module.. need to it spec first ... you aso can run 2 oem ignitor or microtech X4....
