hello fellas

Currently have a HKS fcd wired in to my ecu loom but it keeps dipping my volts all over the place and lowering my engine idle revs to keep the car under fuel cut, so ive bought a Greedy BCC as it does the same job but holds the volts more steady but would like to know which way of wiring it is better, either into the ecu loom like my HKS fcd, or into the map sensor wire in the engine bay, both do the same job and are simple to do. And is the greedy BCC adjustable as the HKS one is, ive set my HKS fcd at 8.

apriciate any helpfull feedback

thanks

Graham
