Set me straight on MAF and injector interaction.
I've searched a little but have found nothing that entirely removes my confusion on this so here we go...
I’m soon receiving an inlet manifold, injectors, 70mm MAF and T/B all from an ED XR8 Sprint. Currently of course I have the stock 55mm(?) MAF, 19lb injectors and the 165kw EL V8 ECU. Now I hear that the ED Sprint gear has blue (that is 24lb) injectors and my question is this. If I install the larger MAF and the injectors to match from the Sprint, will my AFR be unaltered or will my computer now map air/fuel points incorrectly. I tend to think the calibration would be alright but I’m really just speculating.
Another thing I’m hazy on is how you can realise different injector pressures without alteration to the fuel pressure regulator. Are the injector “sizes” purely a measure of maximum deliverable fuel pressure? If so will the installation of these 24lb injectors mean that I will still only be injecting at 19lb if I do not touch the fuel pressure reg? Can I wind up my current regulator by this much (I know they can be adjusted but this far?) Will I need to?
Thanks for your input.
