I finally got the 406 TPI to idle halfway decent, yet the BLM's at idle show 108 still. When I take it out to cruise, they level out about 116-118 and pretty much stay there. What should I try now....?? Am I getting into PE mode? I havent found out how to exactly check that yet.......just wondering if anybody had a suggestion on where to look next. My air/fuel is staying on the rich side as well...so I guess the BLM's are correct....any ideas??? thanks in advance...

 

Lower the VE table cells where you are running rich. That should bring your BLMs in line.

For better driveability modify the BLM MAP and RPM threshholds so you hit more cells. Also consider changing the constant "Force BLM Idle Cell when CCP DC Less Than"

My car idles in cell 12 now ... and idles beautifully (albeit with a big phat lopity lope).

Trax,

How did you get the car to idle in cell 12? Mine always goes to cell 4 when at idle. My car (383,AFR 195, 236/242) idles at 925 around 70-75 KPA. Should i change the cell 4 boundries for MAP and RPM to reflect my idle RPM and KPA? I'm using the stock AUJP boundries right now.

 

The boundaries are not with respect to cell 4. They are just the overall boundaries of the BLM cells. See the image that I posted in the following post ...

See how it is like a grid? MATCH your driving around data (MAP vs. MAP vs. BLM Cell). Compare it to the grid. You should then be able to see how changing the boundaries will allow you to hit more cells when driving around.

With regard to the idle cell - try changing what I mentioned in the previous post about the Force Idle cell CCP setting.

Thanks Trax,

I just put my car up for the winter. I'm making a list of things to do over the winter, and first chance i get in the spring i'm going to play with those cell boundries and "Force BLM Idle Cell when CCP DC Less Than" values.
