You can try map 3 and log it to see how the car is behaving. I run 24-25 psi on my map 6 on pump gas depending on the fuel quality

Anyone tested with catless dp and JB4?

[mattburks]

Just picked up my 6MT from Cedar Performance here in Dallas, whom helped me with JB4 and a few other misc fun items today. Short time back with car is eye opening. Running map 2 with quality 93. Shop looked at logs briefly before I left, and said they look great. The mid range is now alive and up top is a different animal. Sample size is short so far, but throw me in category for another +1 as a “must have” for the 6MT folks. Sorry, no dyno numbers, shop squeezed me in last minute already, and was on borrowed time — however I’m going back for my BMS intakes and might be feeling sassy enough now to pay for a few pulls. Is anyone else planning on dyno’ing 6MT base with JB4 soon?

I’ll be back in shop in roughly 2 weeks is plan, so that would be my earliest eta to provide.

Hows the fuel economy for that?

Do you plan on trying the map that allows for E30? That should really wake the car up

B58SP great question- for some reason the thought of running a blend stresses me out. That being said, yes- I bought the mobile connector for that soul purpose. Will try and behave and enjoy the +3 lbs currently on map 2 for a bit is my mental approach as of this moment. **Subject to change at drop of a hat

Has anyone with a competition ran logs and seen what peak boost is on competition model is ? I'm curious because with the 6MT we are down boost from the get go and running map2 should technically make it even with competition map1. Only running 91 but map2 seems great on my 6MT no timing pulled or boost.

I have the downpipes ordered but just got an email saying they won't come in til mid December =/. I'll be on SSR cdp, JB4, and BMS front mounted intakes.

[kingmonkeyjr]

Anyone looking for a JB4 ? I sold my car and have one! PM me if interested. Can save some money versus buying new!

You dirty dog, you! Congrats on the sale. I enjoyed our time together as fellow JB4 6MTs.

I can safely say it's the best M car made to date but when money is waved in my face I'll always take the money

VonB what swayed you away from install out of curiosity?

VonB as will I once it becomes a bit easier logistically with the ECU. I saw a quoted 5 days to DME unlock to and from Russia and back… something about these OTA updates weirds me out

I just got my Downpipes, mid pipes and jb4. hopefully to get it installed in the next week or so.

Are you planning to dyno it?

Did you see any throttle closures too?

Looks like it works better in comfort (all the maps), still not sure why it happens.

You are not going to notice the throttle closures, you would only seem them in logging.

[mattburks]

To gain clarity - is it that more power is actually generated in efficient mode when compared to sport & sport+? or more-so just a cleaner log when in efficient mode vs the latter?

Is the throttle body closing mid pull damaging to the car/fuel pump etc.? Is it providing a less powerful pull in regards to wheel hp/tq on these hotter settings compared to efficient?

Trying to word this any & everyway possible so that everyone understands what I'm asking lol.

edit: I've just been crusing map 2 for about 30 days and dumping in decent 93 octane.

Sounds like if you use a dragy to measure your 60-130mph times you'll be quicker in comfort mode than sport+ at least if you have downpipes. Everyone always turns on sport+ because they think the car will be faster that way but its actually the opposite.

I am so sincerely looking forward to the active sound input update with the new IOS then -- this will solve audible issues if it also opens up the valves on the exhaust. Thank you BMW!
