need help map sensor not working correctly Hello guys, i need some help. My map sensor is supposed to be a 3 bar but it only shows 15.2 psi at max. Im running 11 psi according to the boost gauge. At idle the map shows 8 psi, and when i start to boost it, the boost gauge shows 2 psi and thats when my map is at 15.2 and it stays there even when i actually run more boost. Any help appreciated. Heres a log file and the tune. The tune is no good yet but i first need to figure this out before tuning it out more. The map sensor is already the 2nd one i put on there but makes no difference. Thanks.

You need to add/insert the 3bar map sensor into your table (primary) in the scanner in order to read higher than 105kpa which is all the factory sensor is good for. Also change your boost enrichment table in the tune immediately before damage is caused from running lean. Right now you are commanding 14.7afr at all boost levels.

Also your timing tables need some work. You are commanding negative timing values in the upper range of your tables. To start I would change all cells to 14* between .64 airmass to 1.20 from 4000rpm and up

to change the MAP sensor values open your tune,click on Engine Diag tab > Airflow tab > in this area is where you will see the map sensor linear and map sensor offset values. Just enter in the data as you received it in the corresponding tables.
