Aloha guys,
Searched around but only come up with 6 pin tps to MSII or other compatabiliry answers, so...
scanvaged 3 pin variable tps's from various bmw's and wondering if they'll just plug into oem location without wire swaping ? they're for my m20 with itbs and miller w.a.r./maf combo.
mounting it is not a problem, just need to double check wiering, thanks.
volt readings varied between them.
switch 1: .062 to .456 V
switch 2: .105 to .504 V
switch 3: .120 to .632 V
my m20 harness plug:
pin 1, br/bl, signal
pin 2, brown, ground
pin 3, brown/black, 12+V
all 3 variable tps work as follow:
pin 1, at close position, .062 raises to .456, .105 to .504 and .120 to .632V's at wot.
pin 2, ground ?
pin 3, at closed position .456 droping to .062, .504 to .105 and .632 to .120 as turned.
So, I'll use switch # 1 with lowest Voltage readings, it seems like it should work unless motronic 1.3 only reads on/off oem type switch. any ideas ?
Mahalos,
Frank
p.s. just cut up carbon airbox for it to clear brake booster, now I'll have to get her patched up, also modified throttle cable bracket for it.
