Thanks for the reply. I think I must have misunderstood the concept of piggybacks then. Ill do some more research on sau

Hi, this is probably a daft question. I'm looking into using a kurofune on my upcoming rb25/30 auto. It's in a stagea, and need to keep the standard ECU to run the auto so have been looking at the kurofune to use as a piggyback. I've been tidying the engine bay, what OEM sensors and wiring will I need to keep please? I'm looking to run map sensors, does the MAF still need to be plugged in? Same with the cas, I'll be using a trigger kit, do I need to keep the OEM cas wiring for any reason? Hope that makes sense. Cheers.
