Hi, complete novice - help needed

Hi all,

I purchased a car running Ecumaster black. It was tuned, and only recently have I connected a laptop to it. I’ve found two things - first the TPS sensor is set max at 5v, but the sensor only wide open only gets to much less - hence max reading is 64%. The second is the map is reading 105kPa when engine is off, which high seems high.

I don’t want to correct these sensors as I’m worried it could affect the tune and I’m not knowledgeable enough to be confident. The car seemed to run fine before (currently having an issue with my spark plugs as they got some water in them). Is anybody able to share any light on what checks I should do before correcting these sensor readings?

Hi,

MAP at ignition off is ambient pressure. 105kPa is a normal value.
For TPS…share ur project plz. There is no need to fully open the throttle. Especially at low rpm u already get full flow with around 50%. For good linearity of trq it is intended to calibrate it like that. There is a map with PPS vs RPM vs TPS…i guess there this behaviour is calibrated and intended.
So i guess u have nothing to be worried about.
