(If it has a second potentiometer that it has to compare with then if the voltage rises unexpectedly on one side for safety reasons it will go into limp)Yes i see what your saying but thats why thats why one track is 2v w.o.t. and other is 4.1 w.o.t. I Can see the 5v regulator may go faulty and send both up (chance in a million)but then again lets go old school what did we do with old throttle cables sticking,I think theres a lot of ifs and but with this one but cant see the ecu not going into limp if the 5v regulator did go mad.
