Apparently it's common. I spoke to the dealership and he said if it's driven hard and if I have a piggyback (yes, the SA knows and he's fine with it as long as the service center's computer doesn't detect it), it burns more oil. He said he's had other G20 330is and M340is come in for top ups. He said there's nothing to worry about for now. Unless I stress the car too much and blow up the engine. Lol

BMW wouldn't claim a time that the car can't perform as that would possibly open the company up to litigation.

remember that the mags publish the best time out of who knows how many runs they try (all of which are extremely abusive) on prepped surfaces (often, all the time, or rarely, depending on the magazine and their ... "relationship" with the manufacturer) in the best conditions on good tires (even if it's the "same" as yours, they're probably in better condition than what you have on your daily)

None of which is replicable in the real world (on command)

ALL of the above ... and you also have ... rollout

Yup. Most magazines here factor in the roll-out time.

That's one of the best stock drag videos I've seen. Those numbers are the same as what I get (not the 0-60 but quarter mile time). Plus, like I've mentioned before. The road I do it on is inclined upwards even though dragy says it has a downward incline.

Run from today:

Only other mods other than JB4 and E25 is weight reduction (low fuel light had gone on)

Impressive. Hoping the Dinan flash will bring similar #s. Is E25 similar to 93 octane?

Yes. I'm hoping for more brands to bring their tunes out for the new B46s. Numbers should be similar though.

And E25 is basically 93aki along with a couple of gallons of E85 thrown in. E85 helps a lot with timing corrections. I throw in 1.9gallons E85 with 6.1-6.2 gallons 93aki for a half or 3/4th tank full of fuel. If I fill her up, I usually do around 3.5 gallons E85 and rest 93aki fuel for a full tank.

From what I understand, Dragy does not subtract 1-ft rollout (approx~ .3 seconds), like major car reviewers like Mother Trend/Car and Driver do. So Vipin's 13.15 second quarter and 4.74 0-60 time translates into a publishable time of
12.85 quarter and 4.47 0-60MPH.

Car and Driver achieved 5.4 seconds and 14.1 quarter mile, and that was on their old standards. And by their new testing standard, most cars record .1 second faster times https://www.caranddriver.com/feature...hange-rollout/

My best was 4.6 0-60 and 12.85 quarter mile (without factoring in roll-out). Car is still as fast. Very fast. Very smooth. Totally love it.

100-200 is similar to a stock 340i too. Only issue is damn thing is limited to a real GPS speed of 125MPH. If only the JB4 could unlock that as well.

Have you considered the Dinan Bench tune? From what I understand, it is easy enough to perform yourself. The only downside for me is parking the car for a week for Dinan to unlock my DME/ECU.

Reason I haven't is because I don't know if I'll be keeping this car. But I might. If so, I'll be getting a DP and a proper flash. Most probably BM3 or something.

We're all of your runs done in comfort mode?

No sir. Sport plus.

Car doesn't launch in comfort mode IIRC.

I have stopped looking for 0-100 times and focused more on nordschleife times.

I've been running this map for more than 10k miles with zero issues. I don't push the car and launch it very rarely nowadays. I love how it feels almost like a remap instead of a piggyback.

Trap speed was slightly more than 107mph. I don't have the dragy app on this phone so I can't check but I can post the actual speed after I get back home tomorrow.

Edit - Just checked the app. Trap speed was 106.25mph. Not the highest trap speed I've got (highest was 107.5mph).

Hi vipin can I access this what's app chat . I'd love to gain some knowledge about our platform

While not specific to the G20, Navardi tuned discord is focused on the F30 and G20 4cyl variants. You will not find more knowledge anywhere else.

There are some great resources there, they also put together this wiki that's packed with info https://n2xandb4xwiki.notion.site/n2...1e34e776d5156f
