Hi guys, I recently installed my JB4 on my N20 328i EWG.
Right now I only have an Injen Cold air intake and chargepipes.
which map should I run? Right now im on map 2. But I don't feel the car as fast as it should be. Which means I should be having around 260-270HP at the crank I believe. I don't know if throwing a downpipe it would make much difference with the map, but I am looking for a downpipe to put.
So MAP 1 or MAP 2 for CAI and Chargepipes?

Map 1 or map 5. Map 2 is designed for downpipes.

So i guess map 1 runs better thsn map 5?

Map 5 is auto tuning. I use it on my N55 since it auto adjusts depending on how much e85 I use. Once I get my downpipe installed I'll log map 2 vs 5 to see which my car likes better. You're better on map 1 if you don't really have any other mods then intake and CP

I have DP and use E85 on a regular basis and normally just keep it on Map 5 regardless of ethanol.

Thanks for the reply guys! So is better for me to keep it on map 1 unless I get my DP. I didnt feel the car much different than stock with map 2. im going to play and see with map 1 and 5. Once I put my DP ill go back to map 2

I just changed my car to MAP 1. I also have a doubt about the OBD menu(speedometer menu).

'OBDII In Dash Menu
'***************************************

'0 map menu, map shown on tach
'1 Active Sound MUTE (not relevant for most N55 models)
'2 Boost gauge on fuel, scaling in dash is 0 to boost safety setting, turns on when gas pedal is pressed 50% or more and turns itself off when you resume low throttle use.
'3 LED MAX brightness mode. For those with factory LED headlights this option brightens HALO during nighttime operation.
'4 OBDII Diagnostic Code Delete
'5 1st gear boost limiter
'6 2nd gear boost limiter
'7 3rd gear boost limiter

Menu 5/6/7 are they suppose to be on 0 or 1? I have menu 5 on 1 that means it has the limiter right?

RPM/200=boost limit
EX: 2000rpm/200=10psi limit

oh thanks for the tip! thats another thing that I should touch? I have 5 in 2000rpm and then 6/7 is in 0

If you want more power get catless downpipe, dont run JB4 map 2 on stock DP

So is that to say that on a '14 n20 car with jb4, cat less down pipe and cat back exhaust...when running e85 I should be running map 5?...I normally run map 2. Does map 5 adjust timing plus or minus depending on how much e85 is being used and if it's sensing detonation? Where as map 2 doesn't adjust the timing on e85?
