How these work then? Like they put on RSTs etc.

How much are they?

On boost pressure? Throttle? Revs? Both?

Is it actually mappable amounts of fuel from the inj, or just on/off?

And if they can do it all, is there a shonky bodge way that is just on/off of adding extra fuel when on boost?
Say, i duno, off a boost pressure switch like with basic water injection?

MF2 is based on an open-architecture design, which means that the unit is freely re-programmable at any time, open to any one who possesses a small screwdriver: no computer interface is necessary! ... working alongside the original ECU, the MF2 controls its own set of injectors, four high-impedance injectors and two low-impedance injectors. It is able to use the signal from the existing sensors, or it can operate independently. 3D-mapping is simple if a load- or pressure- signal is fed into the unit

im sure its £200 jus for the driver, but its a bit of a crude way to gain extra fueling, i cant see the fueling being "spot on" all the time their used!
I think it works off coil volts but u can get optional Manifold absolute pressure(MAP) or optional Throttle position sensor!

 

Ok then, how about a REALLY bodge way of adding fuel when on boost, like, i dunno, injector activiated on a pressure switch like water injection does....

Ive seen this done once using a cold start injector, it was a bodge, but it gave the fuel to stop it running lean and blowing up...

 

no neeeeeed to bodge it. see your other post on this subject.

megasquirt is your answer - less than 200 quid for a fully programmable MAP based injector driver

 

Steve, is this how you plan to fuel your skyline engine?

 

steve secret fuel mod

 

No, i think the 6x1000cc inj, 2x 044 pumps, 1x intank feeder pump, 2litre swirlpot, and SX regulator does that nicely you sarcy coont...

 

With that sort of combo surely you'll be knocking on the door of the break down recovery truck?

 

what car is it for steve????


reno 5???

 

steve is this a saftey measure then


i knew ya would give in and take the car to galbally motorsport in the end

 

na mate ya need a a 5th injector, why bodge it mate

 

Wow, your nearly as funny as a 10 year old boy called Karl, Ginge

Spikey- No, a really really shonky half finished turbod 1985 325 bimmer i have managed to aquire

 

oh dear...lol


sounds like fun though

 

steve


ya know ya love me really

 

Stu @ MSD sells the 'bodgeit' ones which supply a set ammount of fuel @ pre set Psi They are like £125 i used to have one to fuel my RST. (worked fine although there is no way of mapping it)
With the erl ones they are FULLY mapable but cost a fortune! i will be getting one of these in the near future for my cab.

 

Have a look at this BM Steve, think you'll find it interesting!

Seen this on the web a few times, Bosch cold start injector whacked directly into the main fuel rail switched on by an adjustable pressure switch. Crude but in the case of the car you mention who cares?!

 

I wonder if this POS has the oil return above the oil level, never looked, never realised it was needed actually...
