Hey guys, if anyone is running a Microtech ecu to run a twin RB26 or 25 head could you please be so kind as to tell me the IDref and TDCref settings? Unfortunately I accidentally loaded a map into my ECU from when it used be a single cam RB30 and now my car won't start. I'm currently running a 26/30. So if anyone would know these settings please let me know! Also if anyone knows if there are any other critical settings that I may have overridden and that I need to change to get it to fire up could you also post that. Hopefully I don't have to send it back to microtech again to get the RB26 details loaded again. Thanks guys ---------- Post added 07-12-14 at 20:38 ---------- Got it sorted. For those who are interested: IDref = 22 TDCref = 50
