Thomasnorthin Posted September 6, 2021 Report Share Posted September 6, 2021 Hi everybody, first time posting on here. Im having trouble getting my rb25 running right with a monsoon, I know its not the ideal setup with only 4 injector drives and 4 ignition. I've got it as far as idling very roughly with throttle input but when i go to set the base timing it is so far off the target that i cant get it there without the car dying. Seems like it could be around 100deg off at an estimate, when I am setting the calibration on the trigger calibration my target is 10deg btdc but once I change the offset to get the timing light closer to the mark around 30deg either way it doesn't run anymore. Im thinking i've got something wrong with settings but unsure what as I am very much a novice here. I've attached my tune file if anybody is able to have a look that would be awesome. Running sort of.pclx Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 6, 2021 Report Share Posted September 6, 2021 The offset is a bit variable in RB's, but try setting it to -85 and see if the timing marks look closer. Also with wasted spark make sure the timing light is set to 0 advance if it has an advance function on it. Quote Link to comment Share on other sites More sharing options...
Thomasnorthin Posted September 7, 2021 Author Report Share Posted September 7, 2021 Thanks Adam, I've give that a go today and no luck i set the timing offset while turning the starter motor and and the offset was 65 degrees, but will not run like that at all. I have just checked mechanical timing and its spot on. I have confirmed that each coil works separately and in their wasted spark pairs using the ignition test function. firing order 1-5-3-6-2-4 Am i correct in connecting: inj drive 1 to injectors 1 + 5 inj drive 2 to injectors 2 + 4 inj drive 3 to injectors 3 + 6 ign drive 1 to coils 1 + 6 ign drive 2 to coils 2 + 5 ign drive 3 to coils 3 + 4 when it does run it definitely doesn't sound like al 6 are firing Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 7, 2021 Report Share Posted September 7, 2021 Yep, wiring sounds correct. What do you have for coils/ignitor? Can you give us a log of it cranking or running. Quote Link to comment Share on other sites More sharing options...
Thomasnorthin Posted September 7, 2021 Author Report Share Posted September 7, 2021 I've just got rb25det coil packs that don't require a ignitor heres a log of it on the starter motor rb25 no fire 3.llgx Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 7, 2021 Report Share Posted September 7, 2021 Nothing much leaps out at me in the log, everything looks happy. So your coils are definitely the S2 coils with 3 bolts? I would suggest also try spraying some starter fluid or similar into the intake while attempting to start to confirm it is not a fuel related issue.
