Not really sure if this should be posted here or on a new thread..........

I'm after a few more items for the car from BMS and am considering the BMS intake. I have however seen a few reports of people experiencing thing such as rough idle.

I have a few thoughts why this may happen and was wondering where we were with things like running MAF'less on an E82 N55, either via the JB4 or MHD, and/or whether anyone has had any luck changing any of the MHD tables to try and help if the sensor is still connected?

Thanks

Hey Terry I was thinking of running your bef with my JB4 but when researching i found a thread from a few years ago that you said there isn't a reason for bef on oem turbos. What has changed since you posted that in 2015 or would you still say there isn't much point?

The gains remain minimal with the E series N55 stock turbo JB4 only vs. JB4 + BEF but it's a lot cheaper now to add a BEF than it was before. Go for it!

This happened to me last week. I had to kill the app and reopen it. Worked as usual from there.

It is smoother though with the BEF. I'm running the PUMP bef now with N55 E-series.

If I have no plans on going to a larger turbo, would you think I'd be happier just doing flash only given my engine (late E-series N55)?

That is a silly question to ask the man that made and sells the JB4. If for any reason you're unhappy with the JB4 then you should try it. You lose some features that the JB4 offers though. I made the switch from JB4+BEF to flash only. Overall I am happy about the switch. I am making less power with flash only however. (see trap speeds in signature)

I already have JB4 and have been using it a while. Just got the DME unlocked and tried out the BEF/JB4 combo. Smoother and I like it.

Just curious if he would recommend going to MHD flash only given my E-series N55 (given that the BEF doesn't do much on this engine, more power flash only)? Money's already spent with Terry.

My point and final comment to not further derail the topic is that there are more JB4 bolt-ons that you could buy to work with the JB4. If he were to openly recommend going to MHD only it could be detrimental to his future customer base. To suggest someone should go flash only would mean that there are benefits to making the switch that cannot be met by JB4+BEF. I do think it is important to gather other people's opinions or to try it if you're curious. I just found it silly to ask the creator of the JB4 if he would recommend not using his product.

I'm just curious from a testing perspective on power. What they've found, etc. What sort of Add-on's are you referring to for the JB4? Meth?

Absolutely, having the JB4 on hand has a lot more to offer than is possible flash only. And you eliminate the costs of paying someone to custom tune a flash map for you. Details of some of those benefits are in the first post.

Perfect, I like the combo. I figured I can run my usual e30-40 mix on the E85 BEF and adjust the boost accordingly with the maps (map 5 now). I heard you can create a custom BEF for my vehicle/mods/VIN#? If so, I can send over details.

The BEF files are posted fully unlocked and a few forum members have started up tuning businesses helping customize aspects of the flash itself and JB4 settings to your specific needs. Trebila and Wedge are popular options!

Welp just ordered my FMIC and will be FBO next week. Going to find a nice cheap $50 insigna tablet from best buy and do the JB4+BMS BEF.

I personally love JB4. I hear how great MHD is but for someone who likes to tinker, can't beat a JB4+BEF Open Maps. w00t.

Terry, I thought I saw an email come through announcing a new map pack?

Not ready yet?

I've been suffering a false boost leak code (2906) when cruising at high gear and low rpm. When I go to pass someone and "lugg" the motor to pass someone is when it happens.

Thanks!

I saw in an earlier post that there is a Pump THR map that we need to email in to get? I am experiencing some random surge and lurch with my BEF. It is very tiny, but noticable to me. Wondering if the THR map will fix my issue. 2011 E90 FBO with xHP on the Pump flash running E30 mix.

I do have linear throttle mapping checked on MHD, could this also be the culprit? I do experience seriously lurch on cold starts with the fan on, but I attribute that to the cold start delete via MHD.

Any news?

I am experiencing a 387F code as well. Was instructed to change power from the 50A fuse to the boost solenoid wire. Going to see if that eliminates it. I don't believe this is associated with the surge/lurch I am still experiencing.

If/when you do this can you please update if 387f code goes away as well as list of parts or materials and a write up of how you did it. I am experiencing the same code and cant figure out why
