hi, ive got a set of blue 24lb au injectors and a 75mm maf and electrics sitting on the shelf doing nothing so i thought id replace the 19lb ef injectors and the tiny 55mm maf.

would all of the au gear run alright with the ef xr ecu or should i be worried about afr's

also i know the plugs are different from the 2 models so im going to have to aut and solder them but that's ok.

cheers

Use the 55mm hotwire on your 70mm AU housing. Leave you 19lb injectors in place. The 24's will run too rich.
If you were able to utilise the 24's... soldering connections is a bad idea, you want to use brass crimps and adhesive heat shrink if you have to cut the harness.

my ef xr8 has au maf (i assume eseries electrics)
but has 19lb injectors
is running like a prick at moment but has aftermarket ecu with s**t tune in it so im blaming that at moment.
