16168625 BHAN modifications for TBI to TPI conversion questions>>

[EagleMark]

The reason I suggested switching to $0D is because so far all these PCMs can... no if you only have one injector driver we may have found a difference?

Also your BHAS was superseded twice to BLCR so that may be a better start.

Six, he was just advised on another forum that there is no need for resistor change? The TBI to MPFI doc clearly states:

Injector Drivers

Next you will need to change two resisters in the PCM. This modification is necessary to disable the Peak and Hold function of the injector drivers. The resistors are called sense resistors and sense the current to the injectors. The resistors have to be changed in order to run 8 MPFI injectors, 6 is OK but 8 puts too much current load on the resistors.

Port injectors come in two types: Peak and Hold (low impedance) and Saturated (high impedance). This modification only works for Saturated (high impedance) injectors.


You will need to remove the stock resisters and install a solid wire jumper in there place. It would be best to check with a electronics store, as to the best type of wire to use in this application. Another option is to salvage a couple pieces from some other dead electronic device.

Here's a picture of what your looking for.
