As per title, really, as ive not got a clue!

Ive never had any dealings with them, so its one part ive no idea of, so, teach me please!

Just the simple cheap 5th inj setups like you see on RS Turbos etc.

How is the fueling regulated?

Does it pick up on boost and rpm and go from there, or just boost, or?

Do you have to use a certain size injector or can you use even big fuckers if you wanted?

How do you adjust it?

What they cost?

How, well, everything, ive never looked at em before!

Cheers in advance

 

the controllers are like mini-mappable ECUs

you'll have a number of inputs (ie boost only or boost vs rpm etc.) and a small map (either programmed with a data cable or with a selection of switches on the ECU)
you can run whatever injector you want as long as it's the right impedence, as youre only giving a pwm output to a solenoid, the thing doesnt know/care what size it is

MSD sells his 5th injector, worked a treat to replace my TT one, basically its a boost switch that can be set from 2psi - 20psi if i remember, when the boost switch sees the boost required, it fires the injector, MSDs have 25 settings to adjust the fuel requirement

 

Run high or low impedence also
