The system comes whit a udjustable pressure switch do i have to install it whit the turbo conv.

If i have too install it what`s the best pressure to set it.

Thanks.

No.......

Don't use the pressure switch... it will effectively mean your fuel injector(s) will either be on or off, above the pressure you set.

Instead, you should wire the MF2 unit up to your car's MAP sensor... this way you can use 3D mapping to alter fuelling with relation to boost pressure and engine speed.

Hope that helps.

no point in using std map sensor as there will be no raise in fuelling for boost once you have got to top of std 1 bar range.use seperate map sensor 2or 3 bar range on mf2 unit ,then you will get full use of mf2 ,s functions

you can buy th mf2 without the pressure switch ,for future users ,the switch is meant for use when adding extra injectors to a tubo car,so you can top up the std ones rangewhere the std ones stop

D'oh!

Thats what I meant...(see other threads) You will definately need a higher scale MAP sensor... otherwise you will only be adding extra fuel with respect to engine speed, even when in a boosted state.

you can still alter fuelling when using the pressure switch ,and adjust the fuel delivery ,but only in 2d format not 3d
