0-60 Times Stock, Dinan Tuner, JB4 etc.
Just curious what times everyone is getting on a 21 up that can't be tuned.
I have a Dinan Tuner, secondary downpipes, air filters and an x-pipe to delete the resonator. Mine ran 3.19 with a 1' runout and 3.41 without. DA was 1500' and 73 degrees. Zero incline. I was thinking of getting a JB4 in place of the Dinan. I still have my Meth injection system from my F85.

I did 3.18 no run out and 11.2 at 121mph on RaceChip GTS black. Now on JB4 and it is faster but haven't dragy'd yet. Only mods are BMC filters.
Edit: this is on E25-E30 which I run daily.

I was running crappy 91 Octane. Our gas is so bad, BM3 actually has a separate tune for California. I do sometimes run E30. The only station that has E85 is $6.79 for 91. It's definitely faster with the E added.

JB4 Map2 on a 2020. I think this was all stock besides the JB4 on 93 octane. I've added a secondary cat delete but fairly certain this run was before I added that. Also had my wife in the passenger seat but she only adds about a 100 pounds

Good numbers! You mixing 93 and e85? How much more or less of E85 gal you need to get 30-35e? Not sure how big is our fuel tank either.

https://www.morepowertuning.com/emix Figure about 5 gallons e85 and the remainder 93 octane per X5/X6 tankfull as a ballpark proportion for 93 octane based e30. Keep in mind that most "e85" pumps are delivering less than 85% ethanol. Last edited by cobramite; 09-21-2023 at 10:37 AM.. |

Added some E85. Without testing it, I'd say it was E25 total. It was earlier in the morning so it was s a bit cooler.
It ran 3.01 with rollout and 3.24 without. The E makes a noticeable difference.

are you guys having issues with your low pressure fuel pump that's in the tank by running ethanol daily?
I've been browsing the M5 forums lately mainly to see what issues those guys are having with this drivetrain figuring they are pushing more mods and limits so its a good indication of the weak points of this car. Seems like the low pressure fuel pump in the tank even with stock fuels is a problem and more so for those running ethanol. Common indication that the LPFP is starting to go is when the car stalls after starting or stumbles as it tries to settle to idle rpms. I just changed mine out last night and surprisingly its pretty straight forward. Kies Motorsport has a good youtube video showing how its done on a 3 series. Not exactly the same but it gives you an idea of how to remove the plugs and hoses. Helps to have very little gas in the tank. My car showed 40 miles left and there was still a good amount of gas in the tank when I opened it up. My car didn't stall but i started noticing it would stumble during idling sometimes and almost stalls during warm starts before it corrects itself. M5 guys reported the car drove better after getting a new pump so I'm going to see if my car feels any different after the swap. Alan

Only mods were Dinan intakes and race chip. This run was done with a man almost full tank of gas and 200+ lb passenger
