Can you run map 5 on the jb4?

Not asking bc of the video or results, just wondering if its set up with the same maps as the jb3 on an N54

Looks pretty even. Thats to be expected though right? Advantage of limited slip isnt going to matter when already rolling

Seems about right... Same engine/drivers race. 335i is a bit heavier though.

True... I haven't kept up with Terry's new maps since the JB3, but I'm assuming the higher you go the more aggressive the map. Wonder if map 1 is the only "correct map" for the 1M.

Map 2 is the advised map for the 1M per Terry.

How about in Cali with 91? Map 5 on the JB3 said 93 octane but many Cali guys ran it with no problems. Im wondering if its the same for map 2 on the JB4

Here is a summary of JB4 maps

Map 0: Stock bypass. This is the only map you may use a BT cable with.
Map 1: 13psi (suggested for most stock applications. Conservative mapping.)
Map 2: 14.5psi (suggested for bolt on mods with 93 octane. Close to JB3 map 7.)
Map 3: Progressive meth (see guide to enable)
Map 4: Stock map w/ CAN active. Soon to be our economy map.
Map 6: Custom map. Active but be careful with it.
Map 7: 16.5psi. A light weight race map.

EDIT.. it says map 2 is equal to map 7 from the JB3. I thought 7 was a definite no no on 91 octane

I think your 335i mate has some mods you don't know about

Either dp's or fmic. I tested both individually and they make more power in 3rd and 4th which is where you get taken.

You're right, I believe Terry did mention something about 14.5 psi for the 1M.

I noticed you are in Weston...

I'd like to join in on the fun!

The reason that 335i pulled slightly at the end is because of the weight disadvantage that you have carrying a passenger.

This video makes no sense: I wouldn't mind seeing a logical loss, but the 1M is a lighter car and according to the description it's on a more aggressive tune (map2). There is no reason in the world for which the 335i should have pulled away unless there is something wrong with the 1M or driver can't drive.

The race actually makes sense. We spoke to terry about it and he said the results where as he expected. He said that since it is the same engine that it wouldn't make that much difference if the 1m is on map 2 unless it had dp. He also said it had to do with the jb4, and it adapting to the car. The 335i jb4 was put on almost one month before the race, the 1m only one day.

at higher speeds the aerodynamics start to play as well which are in favor of the 3series.

Do several WOT pulls over the next few days and line up again. You guys should run from a roll and a dig next time.

Terry mentioned map 2 on 93 octane was suggested so not sure about 91. Sorry for the confusion.
