Running In Rb25-30 On Standard Ecu

as long as the ecu matches the head's sensors, it will be fine. From there modify it like any motor, eg if you make major changes like turbo or injectors you really need a retune.

the AFM will look after any additional fuel required due to the extra capacity

Just don't run more than stock boost as the extra capacity, 7psi on a 3ltr will be closer to 10psi - the ECU could well start having a bit of a hernia and going R&R on you as a result, so just be mindful of that if it does start acting a little strange if you load it up a bit.

Obviously you'll get gains from a tune, and really you don't want to be putting a stock turbo back on there anyway. Will still run with a different turbo as long as it's not too big. I could get away with a GT30 on a RB25 driving arough light throttle (and stock everything else) till it was tuned

      Yeah so when you turn key to IGN the fuel pump should run for a few seconds. If you find the fuel pump relay (and have a multimeter, and a second person) to can check the relay inputs.  One trigger pin should be either fully earthed  The other trigger pin should get 12v from the ECU for say 3 seconds when you turn key to IGN, and at all times that key is at START (note, I said this from memory, it may be the other way around, ie one pin always has IGN 12v and the earth has continuity to earth when you turn the key) One Pin should have a good battery voltage The last pin goes to the fuel pump + Also note that if the power to the relay is good, and the relay is working, it is worth checking the pump has a good earth too. There is a computer in the standard system that increases the earth resistance to slow down the pump when not required, pretty old school and it may have failed

      All this talk about fuel and fancy ECUs, meanwhile my poor old R32 has neither.... When the ignition is turned on, should there be power running o the fuel pump constantly or just for the few seconds it usually takes to prime the pump? About to go have another look at it, have watched some YouTube vids on how to use a  multimeter and looked at some wiring diagrams but really have NFI what I'm looking for because electricity is invisible

      Yuh....but weren't all the supertourers, except maybe the Audis, FWD? I don't recall any of the others being AWD.

      They ran them in Oz Super Tourers too https://www.supertouringregister.com/register/vehicle/212/ (I'm so old I remember racing with Matthew Fox) They ran them in Oz Super Tourers too https://www.supertouringregister.com/register/vehicle/212/ (I'm so old I remember racing with Matthew Fox)
