yah, 16b with a 70lagfix. Left everything else on autotune b/c I had the best result with it on the G4 using E85. What does the pid gain setting do? Worth adjusting just to see how it feels or just leave it alone?

I don't remember. The 15 ISO was the funky one that let you set FUA and lagfix for some combined throttle and lagfix thing. It was nice and smooth, but to get good throttle response I felt I had to do a combination of the two settings that resulted in boosting with very little pedal input. You could set it up to take really little pedal to go pretty dang fast. I didn't not like it, it was just weird and bad for the fuel economy. 16 is a lot better.

At a minimum I would set it to map 0, if you really want to error on the safe side...remove it. What other mods do you have?

Well, depends on how easy you can remove them. Do you need to take it to the dealership for a bodywork?

Map 5 starts at map 2 and adjusts up or down depending on how the engine reacts to its inputs. I suspect the main control are the knock sensors.

On 93 octane I tend to get max boost of about 14.5 psi, which is map 2. On 35 percent E85, I can hit 18+ psi -- but I limit the boost to a lower value since I am not racing. I live in Milwaukee though, and the hottest days here do not compete with your hot days.

I've been running this way over 10k miles and had no negative effects. I recently removed the spark plugs and they were wearing perfectly.

So even for race gas, Map 5 should be better than map 2 -- assuming you want the extra power from the higher octane.

This has been my experience. Your results may vary.

Note that when you switch octane levels you have to switch out of map 5 and then back in to reset the controls. Based on the JB4 controls I've seen, this means switch out of map 5, turn off the control menu, then back to the control menu and back into map 5.

EDIT: you also need to run WOT a couple times for a few seconds to let the JB4 adjust.

Oops, I misread your first post. I thought you said you tweaked several settings in 16B to get the punch of 15C back. That's what I was interested in, I also messed with that weird split on 15C.

Once I was able to get a clean install of 16B I much prefer it.

100k and luckily no rattles at all. Car had 68k when purchased so it is possible they could have been replaced. BMW pulled the service history and nothing is there???

I just updated my 135 from JB3 pinout to JB4 G5 ISO firmware, running map 2, I must say it pulls much stronger now!! Power much more linear than before!

Just a little spark like noise when getting off the throttle, normal?

I think he means that Map 5 boost levels start at the Map 2 level and adjust from there.


Cool stuff no longer installed.

No updates there. Heard of a few occurrences of the box deforming out of many hundreds of units in use so suggested those who have the deformation remove the enclosure. We've been working on getting the enclosure made in higher temperature plastic but so far has been nothing but headaches and delays.

No, go Speedo 0 tach 0 to go back to stock. That is, as far as i know, how you can reset the Map5 adaptation values.

To reset you can pick any other map ... say map 4. But you have to switch out of speedo '0' to make the map take effect. So I just leave the menu and come back. You could also got to speedo '1' and back to '0'.

You have to 'reset' every time, which is done by changing map. The reset for 1,7 is about the dials on the dash.

Also, by map 2, I mean that the boost levels, timing etc are set at map 2 when you first switch into map 5 from another map. Then based on the knock sensors and other DME/engine responses the JB4 adjusts boost, timing etc to match the octane. It will go up or down depending on how the engine responds.

With E85 it jumps quickly to 17-18 psi boost. with 93 octane it stays roughly at map 2. I have not tried lower octane in a while, but it will reduce boost closer to map 1 if you cannot sustain map 2 due to the fuel you have.

Once it gets settled, it stops adjusting though -- which is why the need for the reset.

Whenever I get gas -- even if I do not change octane -- I do a map switch out of map 5 and then back. The main point about "leaving the menu" is that the JB4 does not do the change unless you switch the speedo side. Just changing the tach to 4 and back to 5 without changing the speedo does not work.

I hope this helps.
