i installed a shiftligth few weeks ago, and also a tachomotor that i have in the pillar pod,
first when i started the car i found put that the shift ligth is also digital tachometer, but they where way off and both read 500+rpm lower than the oem tacho,
i then found out that the ls1 uses a 4cyl signal,
they got almoast rigth, they are few rpm's under the stock tacho, and there seems to be a little delay beetween them and the stock one, they move upp a little slower,
that wouldn.t worry me tomuch but what is worrying me is that i also have my window switch hooked up the same pin on the ecu, end i was thinking about if i sould worry about a delay there also? or are the aftermarket tacho's just not working rigth?
or is the stock tacho messed up?
best regards
