CSHENG Posted April 17, 2022 Report Share Posted April 17, 2022 Greetings, i have an issue regarding calibration of IAT, ECT and MAP sensor. As i connects the ECU to my laptop, i got this 2 code error code 46 and error code 43. i also noticed that the calibration table for IAT, ECT and MAP sensor was pre-selected for k20 temp sensor. Question is which calibration table should i select . note: i have tried TPS calibration , seem to be fine. Engine = 4age 20v, stock ECT, IAT, and stock MAP sensor. ECU = Link g4x atom ii. ECU harness was built from a 2.5m link g4 harness. all the sensor wire was install with the harness tags. attachment added, kindly refer Csheng4age20v.pclx Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 17, 2022 Report Share Posted April 17, 2022 ECT and IAT should use the Std Bosch NTC calibration I would expect. MAP sensor will need a custom cal. Try something like below. Quote Link to comment Share on other sites More sharing options...

Try something like below. i have made a correction for Temp sensor and MAP sensor. attached the result as attachment below it seems that the An temp sensor Error high have default setting of 0V. Now i put a 5V for the error high is that alright ? Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 18, 2022 Report Share Posted April 18, 2022 I would normally set the error high to 4.95v and error low to 0.05V, then the ECU can detect a failed or disconnected sensor and use a fail safe value. Quote Link to comment Share on other sites More sharing options...
