(but may be able to adapt with a standalone ecu, i have considered this before) still loads to think bout, cheers..........
and you provided me the current to pressure chart, u sir, are a legand. this may be a silly question, but is that chart a standard on all 12volt engines? or just the gte, i am running a ca18det! so use a maf (but may be able to adapt with a standalone ecu, i have considered this before) still loads to think bout, cheers..........
On a EE90 Corolla 1300cc 2E circa 1987-1990 it had a vacuum sensor plumbed into the inlet manifold, on light throttle (high vacuum) it would illuminate a green econ LED in dash and on progressive throttle opening (less vacuum) the LED would change colour to orange, this could be adapted thro a relay to operate magnetic clutch
There's nothing to stop you installing your own MAP sensor as well as the MAF that's already there. It would only be connected to your electronics so it wouldn't interfere with the rest of the engine. This is how the early MK2 MR2s run their boost gauges, they have MAF for engine management but MAP to drive the gauge and fuel cut.
Standalone ECU would probably make life easier, as you could say, under these conditions switch these outputs on and off. But that gets expensive as you would have to make the ECU run your engine first before you started adding functionality
No those voltage graphs are just for the part numbers listed - it was to give you an idea.

D.F!ANT as i said electronics are not my thing, thanks for the correction,
i could have ended up researching in alsort of pointless directions then. i see what your getting at now, makes much more sense! I wouldn't need a switch on the bypass atall and could still manually over-ride the clutch easily, thanks for the info :thumbup:

mice, but would that system be controlled by the cars ecu? i'm running a very limited nistune ecu atm, understanding and splicing anothe cars electronic controll method could be very/too tricky! but that would be exactly what i would want and i will also look at it...

if i could work magic with electronics i could even use that system on a motor to operate the valve itself and eliminate all cables and tubing, hmmmm, even more to think bout, any electrical genius's on here?
yea, i reckon so, and that would give me the electronic signal i need to controll the s/c clutch and wouldn't cost much, and i wouldn't have to overcomplicate the valve itself, love it! i even have spare points on my manifold to mount bits and bobs! time to find a map sensor to play with if i could work magic with electronics i could even use that system on a motor to operate the valve itself and eliminate all cables and tubing, hmmmm, even more to think bout, any electrical genius's on here?
You can pick up all manner of MAP sensors as long as you size them correctly. For simplicity you'd want one that does 0V-5V (some weird ones do 5V-0V) and they are measured in BAR. If you are planning on measuring up to 0.8BAR you want a 2BAR sensor, up to 1.8BAR you want a 3BAR sensor, etc. Basically you take how much pressure you want to measure, add 1, then give yourself 0.2 for a bit to play with.
Rabster is your man for electronics!

sorry phill01, just read that again and realised i read it wrong first time, yea, thats not the car but that is a similer system copied to fire an injector of a vacum pump on a honda. i got lucky with that but she was never quite rite. which is why i freaked out when i thought you meant a splice, i have actually found a pressure/boost controlled switch similer to that already with an off/on operation rather then progressive! i'll look into it too thou, cheers
I used this sensor when I helped adapt a Ford 2.8 v6 cologne engine with a turbo, I plumbed in an additional cold start injector into the plenum chamber to enrich the mixture on boost, long before the days of piggy back ecu's and electronic efi
no it was a straight forward vacuum on/off sensor running off a 12v supply.
