0-60 was nearly .3 slower than Map 1 on the same road (3.58 vs 3.87 on the Dragy), though in fairness, this tank has less ethanol in it.

Map 2 hasn't been developed for the 523hp engines. Its waaaay too much boost. +6psi is asking for trouble IMO.

PS: To get a clean log with more data sampling. Head to the highway at night and do a 4th gear pull from 2500/3000rpm to redline in manual. I expect you will be hitting over 22psi in 4th gear in Map 2. That's M5 comp boost level...

Yeah, I just tried it again and she did 3.91. This Map isn’t working or this gas isn’t.

Unfortunately there are no highways around me. I’m 25 miles from the nearest one, and that one has heavy traffic all the time. I gotta take it tomorrow, so if I get an opening I’ll work on getting a longer, better, log.

A longer duration log will help with the conclusion, however I suspect without a d0wnp1pe you will struggle to hit targets lower down and up high the boost will come at the expense of timing. I'm reaching 22 degrees at 6000 rpm on pump fuel right now. 23+ with a little extra octane.

Fix the problem and worries of running map2 and having +6 psi of boost? I mean high flow C*tt**Ed!

I've done nothing. Just demodded. My new X3 is scheduled to be out of production on Friday, so I'm not long for the N63 world.

Hoping the B58 is more mod friendly. The part availability is sure better.

Mike, i think it is. I found myself watching a YouTube video of a guy introducing a 3 stage process to get that engine to 600+ HP. All parts seem readily available too. Sad to see you leave the n63 community but I get it. I can't believe I have to ship my ECU to Russia in order to flash it. So painful.

Well that sucks you have been helpful. For what it's worth, I sent a log of map 2 to terry and he said it looked fine. Wonder if ********* and e85 make a difference.

On map 2 you can’t run more then 2.5 gallons of e85 without running to lean, and I also have a ******* ********, my custom settings for map 6 is 5 psi Through the whole rpm range and it runs faster 60-130 then map 2
