setting up my ems 1710 with a bmw tps in a 90miata. So Ive been searching for awhile and am still scratching my head. Finally decided to ask for help. Here is what Ive done so far.
I setup the bmw wires per write up here.
yellow wire --> signal
black wire --> 5v
brown wire --> ground
With that done, i found only 2v output. Found that it was ok aslong as its setup properly.
BMW tps only reading 0 to 2volts in ems
So now I need to setup the ems. Followed these steps.
AEM EMS Variable TPS How To!
Now everything is done, when i try to set throttle range, tps voltage sits at 4.96v for min and max. when i press the throttle, no activity on the screeen.
Ok so check the wire.
red wire --> 5v
blk grn wire --> ground
lt grn wht wire --> signal
Back probed the lt grn/wht wire at the ems and reads the same voltage at the tps signal.
This is where my car battery died from koeo and called it a day.
What am i missing? Bad ems?
any help would be much appreciated.
