| - | If you're really looking to maximize inputs, you can consider removing R39 from the underside of the ECU board. **NOTE:** This is ONLY appropriate for a 1995 EPROM ECU. It does not work on 96/97 ECUs. A different resistor may be present on 96/97 ECUs that can be removed like the 95 EPROM ECUs, but we have not spent any time yet trying to identify it. | + | If you're really looking to maximize inputs, you can consider removing R39 from the underside of the ECU board. |
| It's best to use a couple small-tip soldering irons for this. Heat 'em up, apply one to each side of the resistor and slide it right off. I'm including a picture of the location of the resistor of interest below. I have verified that this does allow a GM 3bar to drive the baro input just fine. Once you have done that, you can use either the baro or the intake air temp inputs for whatever you want. | It's best to use a couple small-tip soldering irons for this.
