[QUOTE="cuscostrutbrace, post: 1063694268, member: 3867"] Wong,yes you're correct...if your wiring is SVT auto,then it would not have a problem to accept BT auto/manual ecu,also the a/c will not affected because the SVT auto a/c signal to the ecu is same with blacktop auto/manual. The problem only when converting SVT manual to BT ecu,but so far i've done almost 20 SVT to BT conversions,so far no customer complaint on low idle,for such conversion,it is necessary to use a/c idle up valve. And also when convert to BT ecu,some may go the 'trumpet' route,hence the low end fueling is greatly affected,a fuel pressure regulator will usually fixed this.Also i will suggest to each customer to fit blacktop O2 sensor for proper running (although most of them didnt bother)...[COLOR="Silver"] [SIZE=1]---------- Post added at 08:35 AM ---------- 6 hour anti-bump limit - Previous post was at 08:33 AM ----------[/SIZE] [/COLOR] I think the caps look different than the earlier svt ecu isnt it Wong...
