Upgraded to the JB4 the other day. Went right to map 5 and have been loving the results (2008 335xi - JB4, DCI, 93 octane). Kudos Terry!

+1 on the exhaust flap feature. Would be nice to easily change back/forth

Upgraded to new firmware during conference call - but can't test for another couple hours. This sucks! lol

Terry - If I'm running Map 5 - will the map need to 're-learn'/autotune again, or will the auto tuned settings carry over (I'm assuming it will reset)? I think I read that it resets even with a map change. Is there any way to make this 'sticky' so that the data it collects will persist a map change?

Just curious to know how those setting changes work.

It will (and should) reset if you change maps. But not if you upload firmware.

What is the CAN_022111.HEX file for? Do I need to upload that as well, or is this for something else? A site search didn't seem to net any results

Do not need that. That is the old firmware.

Not surprised. I think that one is going to be model by model as there are lots of potential commands/modules to interface there. We'll just have to note which models those test commands work for and which ones they don't and go from there.

T, glad you have the AFR curves in there. I assume this is the same scale as the other AFR was (0-100)?

Also, I think I have the 1k resistors in there. How does that effect the AFR biasing that is output in the logs? Does it change the values or just allows for a lower AFR to be reached. IIRC, the fueling resistors just limit how low the AFR can go and there is no difference between the a 3K and 1K resistor at say an AFR of 12.

Sounds good. I love the Flap feature though, and i'm sure you will get those pesky I-drive commands working for every car.

Same 0-100 scaling. So now you get to enter your own curve. On nitrous it will probably be 100 all across.

For many the only useful upgrade is the flapper. It's a lot of back end and higher performance stuff.

I just uploaded the new firmware, I have an '06 build and my iDrive didn't turn off. The iDrive thing doesn't bother me anyway cuz my stations would always change and then it would unmute so I just turn the volume all the way down when I make in-dash changes... Anyway, I tried out the CANflap option and I noticed that I can close it but then a few seconds later it just opens itself back up again, is that normal? I've never played around with the flap before today so I don't know when it's suppose to open or close but I thought it was suppose to stay closed at idle and low RPM conditions and that's why people were rigging it open...

With CANflap off it will do whatever it does stock. I think they open it at idle and close it during light cruise. It reopens under heavy throttle.
