starlet charged Posted October 20, 2015 Share Posted October 20, 2015 turbo map sensor out of a toyota mr2 the same as the glanza ones?? Quote Link to post Share on other sites

Stu Posted October 21, 2015 Share Posted October 21, 2015 Different voltage output curve too, so even if you wired it in the fueling/timing would be all over the place. Quote Link to post Share on other sites
daniel_g Posted October 21, 2015 Share Posted October 21, 2015 Did people used to run these with aftermarket ECUs? Quote Link to post Share on other sites
Stu Posted October 21, 2015 Share Posted October 21, 2015 It depends on the ecu really - a lot of stand alone ecu's either have their own inbuilt map sensor or run a generic fitment map sensor (like GM 3/5/7 bar for example) or an map sensor that the calibration tables are known. Links for example have their own family of map sensors (2.5/5/7bar etc) with known calibration tables but the software also has the tables for the GM units and a few others common units. Its definitely possible to work out the voltage vs pressure table with some careful bench testing (apply levelled steps of pressure and vac etc while using a linear 5v supply then just read the output voltage and create a table from that) so any map sensor can be used but alot of stock ecus wont run up to high boost pressures.

AdamB Posted October 21, 2015 Share Posted October 21, 2015 As Stu said, they need to be scaled correctly, 9.9/10 it's just easier to purchase the correctly rated sensor recommended by the ECU manufaccturer. Quote Link to post Share on other sites
