i'm planning a stage 3 conversion (330bhp) for my Esc Cos soon.
most conversions are with green injectors, but wanted to know if greys can be used also. i've heard that cylinder 2 and 3 run hot on greens
greys should keep things cooler, is this true? what ecu and chip should i use best for this?
cheers

 

I don't think there is an off the shelf chip for this, even if there is i would advise on getting a live map (around £500)

You running P8 management yes? if so that would be fine i should think

I always thought cylinder 3 runs slightly lean due to the air flow/design of the inlet, but a livemap on greens or greys would reduce this risk.

 

Thanx!
I've already heard some good things about live mapping, so I think I'll just do that

 

Live map is the ONLY way that a stage 3 car will run on greys

NO, greys can supply more fuel but a chip will be mapped to supply a cirtain amount of fuel dependant on RPM and load site so therefore you'll probably find that grays or greens will both be mapped to supply the same amount of fuel! An uprated fuel pump wouldn't be a bad idea!!

i've got a Bosch 0 580 254 005 pump, any ideal what the fuelling capacity might be?

 

Is it the original in tank pump?

original one is still in the tank, but i've got that Bosch pump waiting to be installed, this one is ALOT bigger
