'88 m3

Stenz · 09-22-2007

I have a '88 BMW m3; I also just bought the generic injection kit. Can anyone help me with the specifics of fitting this> I simply assume that I can hook the mister into the tube after the AFM box. Anything else we need to do?

What do you have to activate the system, Vac switches we have found are not good because once there is no vac (engine off) the system will spray. So it pretty much has to be a electronic means of activation, RPM switch, or some sort of 5v sensing device.

The rest of the install is no different than any vehicle.

i AM SO NEW TO THIS STUFF (ALCOHOL INJECTION) I REALLY DO NOT KNOW WHAT YOU MEAN REGARDING ACTIVATION. I BOUGHT THE BASIC KIT WHICH HAS ALL THE SWITCHES i HAD THOUGHT YOU NEED TO SET THIS UP. I ASSUMED THAT ALL I NEED TO DO IS FIND A PROPER PLACE TO MOUNT THIS KIT, FILLER UP, AND TURN THE SWITCH ON. AS I NOW LOOK AT WHAT I HAVE, IT APPEARS THAT IT HOOKS INTO MY SYSTEM AND I CANNOT REALLY TURN IT ON OR OFF LIKE I WANTED TO. IS THERE A WAY TO SIMPLY TURN IT ON AND OFF WHEN YOU WANT? I REALLY DO NOT MIND HOOKING IT INTO A VACUUM, LIKE THE ONE FOR MY FUEL REGULATOR AS THAT WOULD MAKE THE MOST SENSE, IS THAT WHAT YOU MEAN? THANX IN ADVANCE FOR THE HELP. I WILL GET IT EVENTUALLY.

Well what you bought is intended to be hooked up to a boosted car. The switch needs pressure to activate. What i would recommend is getting a Full throttle switch, and hooking it up in place to the pressure switch. This way the system only comes on under full throttle, they are very cheap. You could also hook up a normal switch you can get at any local elec store for around 1.00 and that would give you the ablity to turn it on or off.
