I've tuned 100s of Canadian BMWs on "94 octane" over the years and it's often outperformed by the 91 octane those customers tell me they can easily get. It's your car. Run whatever you want to run on it. And it's easy to log/evaluate both to see what works best for your specific needs. But having been burned by that fuel on more than one occasion my advice to anyone who cares to hear it is to avoid it like the plague.
LOL hahaha I was ready to plant A C4 explosive on the manifold to removed the plugs. I feel your pain it took a while to get the right combinations...i needed to go with 1/4 extension because the 3/8 was to thick.Biggest pain in the ass plug change I've ever encountered besides on my Forester's boxer motor.
I didn't take the intake off, I followed the other video that was posted on this forum elsewhere. Still a pain in the ass!
I think it was a combination of slightly too long extensions and too big/fat of sockets and swivels. Finally got it done though!

I’ve been having a great time with the jb4 now that I have stopped my pinging. I may have just got a really bad batch of 94 octane but I’m going to be switching to shell 91 after this tank is done. I added some fresh gas and I picked up a 25L jug of e85. I started slow only added 7-8L and it completely stopped any ping I was having. I was even able to run map 2 and it pulls very good.
Glad to hear that you got your issue solved, but I certainly hope that mixing E85 isn't required to run map 2 on this with 91 octane pump gas.I’ve been having a great time with the jb4 now that I have stopped my pinging.

I’m at sea level. After this tank is run out I’m going to try shell 91. Being at sea level and running the fuel wires I’m guessing I may still get some ping on map2. I’m ok with that I just hope map one is solid. That’s the tune I’m going to be running most of the time.Glad to hear that you got your issue solved, but I certainly hope that mixing E85 isn't required to run map 2 on this with 91 octane pump gas.
Please consider adding your location to your profile - it helps to get a rough idea of what altitude you are running at, among other things.![]()
It’s weird my app used to show trans temp and now it no longer works. I’ll check to see if my oil temp works and get back to you.I've installed the JB4 for a few days and simply love it. A few questions I have and hope you guys or Terry can help me.
1) Why my mobile app cannot show oil temp? Only has water temp.
2) From the log, how to see if it is pinging or knocking?
3) At my place, the petrol sold are based on ron, unlike US which is based on AKI but it seemed like it is generalized as "octane". Any relationship used between ron and AKI. My understanding is that 91 octane is about 96 ron and 93 octane is about 99 ron. I know we need to mon but just hoping for any rule of thumb. My country best petrol is only 98 ron and it seemed that I'll never be able to use map 2 which is 93 octane. We also don't sell ethanol boosted petrol.

It’s easy to update if you have the Bluetooth. I’ve never tried from computer though.@Terry@BMS how easy is it to update the firmware software I found one locally but it’s the first ver1. I wanna buy it since I’m in CA.
