i picked up a older p120 and i was unable to fire it up due to a broken temp sensor.i managed to pick a newone localy but it was from a 120sx,
plugged it in and no temp issue.now heres where some issues begin.it will fire up on the starter fuel (power max) then the starter motor stops and wont continue.
the temp on the gsu starts to go down even tho the engine is hot.
is there a differance on the temp sensors from the original 120 and other verions?
should i not be able to heat up the end of the seonsor and see the temp rise on the gsu?
from what i have been reading and please correct me if im wrong.. the temp seonsor does more that just measure the temp it also allows the caro fuel pump to start and engage the starter motor to continue to raise the rpm of the engine.

Don't know if there is a difference but I doubt it.</p>

Did you calibrate the temp sensor when you installed it?? Hold Select Menu down, power up and hold 10 sec past Learn RC til you get to the calibration??</p>

The ECU makes all it's decisions based on RPM & Temperature. It needs to see a heat rise after light off to continue the start. You can put heat on the tip and you should see a rise. Your finger is enough if you can touch it. Unlikely since you can communicate with the engine but it's also possible your data cable is bad.</p>

yes i did a recalibration on the sensor but no luck..sensor failed..going to order a new one.

well this is what i found out.. the p120sx exhaust sensor wires were soldered on the board backwards so when you tried to spool up the temp would go down..desoldered them and switch and bamm she works.
now im not sure if that was a goof up at jetcat or theres a differance between the 120 and sx version. thought you guys might want to know.
