Hi all. Got a 2WD sapphire running stage 1. Checked my fuel pressure last night and it was up at 4.5 bar on idle. What should the fuel pressure be set at?
Also had a boost gauge fitted and im getting 18-19 psi of boost when it peaks then drops down to bout 15-16 psi and steadys at that. Is this to high?
Also what CO2 should i be getting?

Thanks

What chip do you have? The chip should be written with a set FP pressure in mind .
The standard O.E pressure is 3.5bar at atmosphere (disconnect pipe) which is a common pressure for stg1 .
If you dont know the chip it maybe an ideal time to use one you do know of.

jesus, get this set up asap - you'll end up melting it.

you cant 2nd guess the CO%, or boost pressure.
if its a stage 1 still on yellows & a t3 you are running too much boost.

MSD are down the road in Blackpool, get it in booked in asap, dont drive it in anger

Im a mechanic and mot tester so have my own boost gusge and also can use the emmissions tester to set my CO2. Plus put the fuel pressure guage on and ok to set my own fuel pressure, just didnt know the values of all of the above hence why ive asked on here as i know there all wrong.
Thanks Guys

2-3% is again a common figure to head for but it still is chip dependant really. As above 2nd guessing can be dangerous and really to make it safe and efficent is to get a setup done . If your chip is unknown personally I would buy a known one with settings to suit .

It's not as simple as that though, adjusting the CO subtracts a percentage from the fuel map, so it can up being lean up the top, as said these are not generic values as it depends on what the author of the chip has desired.

1 BAR is typical for stage 1 and so sounds ok, the higher figures appears to be a 'spike'.

as said, the screw on the ecu will adjust the CO% but its a global set up so will affect the whole map not just the CO% idle.

whip the cover off the ecu and i suspect its a chip from the 90's, overfuel everywhere on the map!

you got a wideband sensor?
