Dang24 Posted November 12, 2017 Report Share Posted November 12, 2017 Hi, I'm looking to have the mx5 plug and play ecu installed in the next few weeks, but not sure if it needs to have a variable throttle position sensor or would work better with one? I know other ecu with require one, and wanted to check first. Cheers. Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 13, 2017 Report Share Posted November 13, 2017 The TPS is listed as one of the required modifications in the manual. You can do away without it but you will have some drivability issues due to idle control and accel enrichment not having the best input. Note TPS doesnt necessarily need the expansion harness as stated in the manual - that is just the easiest. You can also connect to AN Volt 1 on pin 7, or AN Volt 4 on pin 6 as these are spare inputs.

Tai Posted October 25, 2021 Report Share Posted October 25, 2021 Hi, the variable TPS needs a +5v supply. Can this be supplied by another pin without the expansion harness? Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 25, 2021 Report Share Posted October 25, 2021 5V output is pin 8. This goes to the MAF in the 1600 model I think. Quote Link to comment Share on other sites More sharing options...
