Has anyone played with the injector driver circuitry (two channel TBI - =
peak&hold) as found in the 16147060 PCM? This box is from a 91-93 =
light duty truck with 4L80E. I want to force the drivers to operate as =
either 6/1.5 A or 8/2 A units, instead of as conventional 4/1 A units. =20
I know that this is physically possible, by tailoring the two "current =
sense" resistors in the circuit, but I am wondering if anyone knows =
whether the rest of the components will stand up to this current abuse? =
Thanks;
Walt.
