By WOT I mean 60% pedal input or more.

Perhaps I'm misunderstanding but I think they are asking is why is a safety mode required if no additional boost is being added to the other maps anyway? Mode 1 is raise boost as a function of meth flow but you will run the same boost on a given map with or without meth flow as there is no "meth adder" to remove with the safety.

When safety mode = 4 is enabled all maps have a base boost of around 15psi and then target is raised to their true target as a function of meth flow.

Nice work, I'm really enjoying menu 11 @ 3000k. Almost feel like I don't need a backend flash the acceleration is so smooth!

Terry, how do I get or purchase a custom map/flash on map6 on the JB4 stage 3 for the n54? I want to boost up more by rpms setting. I want more than map 7 18.5 psi.

I'm have FBO and will only run on racing fuel 100+ octane.

I'm not sure if I have the latest firmware but I bought my JB4 around May 2015 so I'm assumed it came with latest firmware.

I'm willing to pay for a safe custom setup on map 6 where I want to push 20-22 psi. I know that's close to maxing out the turbos and potential risk for the motor but I'm not worry it's only 3k-4k for a new motor. If it blows up it'd just be a good reason to get it fully built.

What's recommended as far as fuel upgrade or meth if necessary to run that much of boost.

Again this setup will only be running on 100+ racing fuel.

Thanks,

The latest JB4 firmware, settings, and back end flash maps are posted to the forum. To run more than 20psi requires an N20 3.5bar TMAP adapter.

Map 7 runs around 20psi so I'd start there. If you need help or tuning advice post a log in the support area.

If you require special tuning attention beyond what we can help with via the forum you will have to hire a personal tuner. We don't endorse any but they are around.

You should start with map 7 and backend flash (race) maps... it will be a good start !

Which would be a stronger flash? Race or e85? It says map up to e30, race for higher, but e40 at least for e85 flash so a little confused. Likeif I run e55, should I use race or e85 flash? Thank you

Anything E40 or higher is better off using the E85 flash UNLESS you often run straight pump. In which case the RACE is a better dual purpose flash map.

Terry, is it a good idea to use b3 alpina flash with mhd/jb4 e85 map 7. I noticed map 7 sometimes causes tranny slip on high rev low gear on my transmission.

Okay thanks.

So historic timing is ignored on all maps when safety mode = 4 including map 3??

10) v31.5: Adjusted meth_safety mode = 2 to apply to all maps when selected.

Sorry but I don't understand which safety mode is applied to all maps if safety mode = 2

Right. Historic timing is meant to protect you against insufficient meth volume or quality to cover the requested boost gauge, and to protect against the rare solenoid failure. But with E85 in the tank these two aspects of the safety system become less critical.

How does 3k feel compared to like 2k? I haven't gone over 2k cause I'm trying to figure out what settings to change to stop the jerky feeling when rolling from a stop ... :/

I guess you need to test by lowering your menu 12 , default 2800 but many reported lowering it to 2600 and 2500 smoothed the issue
