So, I installed a JDM MAP Sensor and did the edits on my Rom 94170715 provided by Evo8426. Works great in boost logging, no CEL or starting issue, but the idle seems a bit rough than usual, definitely noticeable. It was the same map with couple of values changed in the MAP Sensor section. What might've I done wrong?

 

Have you changed the scalings in ecuflash by chance? There are a few that need to be changed. To do this you have to right click on the table in the left window pane of ecuflash. Where it says OMNI 4 Bar you need to change it to JDM 3 Bar.

 

HEy thanks again. I'm trouble finding the first scaling pane, the MAP Sensor metadata table. I don't have one in the MAP Sensor subcategory. Is it just my ROM?

 

He isn't on speed density so none of those would affect idle. Log your EGR duty at idle, only PSI based boost control. If the settings are wrong, it may be opening your EGR valve at idle.

I keep forgetting that not everyone is running speed density, my bad.
