I think it's the TB too, but I should be able to get that tuned out, right?

I'm not concerned with the AFR in boost because that all seems to be ok. I monitor the hell out of my wideband when I even come close to boost.

I'm using the factory MAP which was new last summer.

When I attempted to tune just the idle last night, I enable the INJ 2 map just to test and I scaled the map as follows:


-------500 600 750 900 1100 1300 1500
.25
.5
.75----------------------x
1.0
1.25
1.5
1.75

It idled right about where the is. I let the A/F target map adjust all around it. When I was done the AFR was near 14.7 in all surrounding cells.

Is the acceleration map something I should be looking at to correct this?

 

There is a airflow map called Boost Limiter Cut Setting in EMU. This is most likely set somewhere around 2.7v. This should be from the output on your MAP. Once you are getting to 1bar the clamp is in place so the factory ecu does not see the increased airflow beyond this point. This is where YOU have to add the extra fuel through the I/J Adj. Map. If you don't have this map tuned then you will go lean every time you are in boost. Not sure if this is your issue but sounds possible from skimming over your post.

 

Just in the nick of time Hopefully this solves his problem before he drives the car anymore

 

Back from the dead! I ditched the EMU and went EMS long ago. No more hesitation now
