Finaly some joy for the N55 guys. Map 5 is now available and you going to love it. :thumbs:
Please update the latest firmware below:
7/1 HEX FIRMWARE
1) Improved boost targeting logic.
2) Implemented a BETA autolearning map 5. Currently suitable for pump and race gas, including E85 mixes of 20% or less. For higher E85 mixes see item #4
3) Corrected bug with air intake temperature not showing in logs.
4) This firmware is the first firmware that will support the optional E85 fueling wires, which are required for those running E85 fueling mixes of greater than 20% without methanol. You may run this firmware without the wires but do not run stronger E85 mixes until the wires are installed.
5) Revised methanol map 3 for stronger low end performance and a more seamless transition from no meth flow to full meth flow.
6) If updating from some older firmwares you may need to remove keys, lock doors, and wait 5 min, for DME to reset. If logging RPM goes wacky in log, etc, post update follow this procedure.

Hi all.... Just want to get some insight from you with regards to the jb4.
We have a dyno day this weekend at KAR and im going with jb4 in.
What octane booster do you use and how much of it?
I know best is to get shell 98 race fuel etc but i cant get a hold of it for now.
Is the NF Ultra good? how many litres should i mix it with?
:ty:

G5 holds boost longer and more consistent and car reacts a lot quicker now as well. Seems like the G5 board has loads more intelligence than the G4.
Thanks Rennzport for super quick and efficient service!!! And what really impressed me is that you guys actually did a lot of homework and research on the G5 install and back up etc cos if you did not then I would still be scratching my head! LOL
Thanks guys!

And alot more boost on each of the maps. Map 5 is rediculously powerful. :thumbs:
Installing the Sld & the Cps were a challenge even for an experienced hand like mine. But it was because i was not sure which Db9, BMS was refering to. :=):
Look forward to run the nitrous now with all the additional safetys. :thumbs:
Will post the details in post # 2 on this thread tomorrow.

BMW Car Club Gauteng Excede at KAR dyno day was awesome and my wagon took 1st Place out of all the 135i and 335i.
385Hp and 734nm with no meth as i never activated it:thumbs:
Still can get more out since i only adapted 5min before run and that G5 board needs alot more settings inputed than G4. So will keep posted on future figures when i get these setting spot on.
Savspeed took overall with Sergoi's wagon pulling a 622Hp with boost leak that creaped in.
