Exclamation 320i switching to map 4 - 10-05-2020, 05:04 AM

Hello, I have a 320i 2015, I recently purchased a JB4 without the ewg connector and I upgraded to firmware 7, I went to test it on map5, the problem is that when I change gears from third to fourth it changes the map to 4, I did the test on other maps and the problem is repeated, I noticed that the boost is not over 11 psi and the last safety stored 1 below my settings and logs:

Photo looks OK, but PSI2 manifold boost in the log is higher than throttle body boost, which should be impossible.

Map0 log?

If it's working then stick with it. But something is definitely odd, perhaps the JB4 board itself is faulty.

You could try swapping JB4 boards with a friend and recording a log to compare. If you were in the USA we'd send you another board but being in BR is more difficult with the shipping.
