Citazione:Installing an aftermarket Variable TPS


Though your vehicle did not come from the factory with a variable throttle position sensor, and a VTPS is not required for most of the features of the MegaSquirt EMS, we did setup the MSPNP-MM9093 to allow you to add variable TPS using the factory wiring harness if you would like to. No internal modifications are necessary, unlike the Gen 1. Some features do require a TPS reading, and it can also help with properly dialing in your acceleration enrichments (though your MSPNP by default will use the MAP signal for this, sometimes TPS based AE is easier to tune).

Here is the pinout to use if you wish to convert to a variable TPS.

	Function	ECU connector pin	TPS connector pin	Wire color
	TPS signal	2L	1	Green / White
	Ground	2C	2	Black / Green
	5 volt reference voltage	1N	3	Red

If you're not sure which connection on your TPS goes to which wire, check it with an ohmmeter/multimeter. Observe the resistance as the throttle opens and closes. Each pair of pins will behave differently:

• The resistance between the 5 volt and ground pins will remain constant.
  
  
• The resistance between the ground and signal pins will be low with the throttle closed and high with the throttle wide open.
  
  
• The resistance between the 5 volt and signal pins will be high with the throttle closed and low with the throttle wide open.
  
  

Using these rules, you can establish which pin on the TPS goes to which wire. Note that we have not been able to find a TPS that plugs directly into the factory wiring and matches both the plug and the pinout, so you will need to do a bit of splicing to make this OPTIONAL modification.
Once you have the TPS installed, connect to the MSPNP with the key on and the engine off. Go to the Tools menu and select Calibrate TPS. With your foot off the throttle, click the "Get Current" button next to the "Closed throttle ADC count" line. Then hold the accelerator to the floor and click the "Get Current" button next to the "Full throttle ADC count" line. The maximum reading is 1023 and the minimum reading is 0, but it's rare for a TPS to cover the entire range. It's more common to see the closed throttle reading in the 0 to 300 range and the full throttle in the 700 to 1000 range, but as long as the full throttle is more than the closed throttle by 200 counts or more, the TPS is functional. If the full throttle count is less than the closed throttle count, switch the ground and reference voltage wires. Once you have obtained adequate numbers, click the Accept button and it will save the values to the ECU.
