Resto mod trouble Open loop when ECT going too high lost power
Corvette 66 with 5.3 and 4l60e on a tci trans tool
we have a BIG trouble.
ECT is going crazy and once it reach 268, car switch to openloop and i have ZERO power after
see log fil at 5:52
it command 12.99 then i lost everything
we try unpluging the ECT harness
we try to make an open loop file and command 14.7 to test it.
i really need some help...
700r4 was reaplace w/4l60 and we replace the dash with a digital one.
so we think a wire or bad ground but we cant find it
ECT gauge in car is around 210 but the ECT in hptuners is going crazy.
we made a test with a digital thermometer and the value is around 205
i just want to eliminate the calibration trouble before going elsewhere
