I liked the video where they're ripping donuts in a parking garage. Shows just how great xDrive is as a "fun" AWD system.

Oh yes. The xDrive is so much fun. Especially with the stock skinny RFTs. I was slipping and sliding all around! The PS3+s reduced that significantly but it still is so much fun.

I have the 225 RFTs on the 19" 791m wheel. Thinking of going 245 square with the AS4s for my next setup. Thoughts? I think the sidewall on the 225 leaves a lot to be desired on the rim. Not a fan of the pronounced lip it has that recedes back to the contact area.

I'd definitely go wider if I were you. The 225s are way too skinny. I stuck with 225s because I have the 18" rims and the max it could take was 245 but I couldn't find any in that size. And I didn't want to upgrade to 19s and end up having another set of wheels in the garage for years to come.

So I just did a launch today and I’m noticing for the 2nd or 3rd time that my car will go past the redline like right up to 7000rpm. Is this normal? I feel like it should be sitting around 6500 latest. Anyone else experience this?

Yup. I think around 6800rpms or so. It's normal

Ok, that's a relief! Btw , how did you route your jb4 obd2 plug into the cab? Did you use the door method or ?

[JTYAMSHAYIN]

So I have a new best time to 60 with just jb+ and some E85.

Did two runs,
1st run was 5.28
2nd was 5.14
Both per dragy.

I tried getting the 1/4 mile on the second run but had my window down and misheard the app saying 1/4 mile and started braking before it was actually done. Would've tried again but didn't want to push the car too much doing runs today, it was already getting warm and I was hot in the car.

I'll have to try jb4 so I can see what i can get using maps actually designed for e85.

[bquatt]

I did a quick 0-60 run the other week. Conditions were hot and on a slight incline. I don't have a Dragy but when using a stopwatch on the video I come to around 5.1 seconds. Car is completely stock. Again, unofficial time but I was impressed considering the windows were down and the road was less than ideal. Wanted to get a baseline before I eventually flash the Dinan software.

Pretty quick! Was this a rolling start or from a stop? Also our speedometers run a bit ahead so just keep that in consideration for "legitimate" 0-60 times and 1/4 mile times.

You can probably compare videos and see if any improvement with the piggyback but you likely won't get a legitimate time by just using a stopwatch, unfortunately.

I've used GPS via my phone before and my speedo was spot on, for what that's worth. It was a launch but unfortunately I didn't get the video rolling in time to capture the stand still. I am standing by my 5.1-5.2 time haha. BMW claims it and the automotive journalism outlets all were able to repeat it so it's gotta be possible in stock form. Is your car RWD?

[VipinLJ]

JTYAMSHAYIN Yes. I routed it through the door jamb. Makes installing and uninstalling significantly fast. Also, the cable doesn't bend and crack. Been two years and it's fine.
JB4 doesn't have any E85 specific maps. You'll need a proper flash tune for that. Even then. It'll probably E50 at best. You can run around E20-25 easily with the JB4. Helps with the timing.

bquatt Like JT mentioned, it's best to do a before and after speedo recording to see if there are changes. The only way a stock 330i xDrive will do a 0-60 in 5.1-5.2s is if it's downhill.

[bquatt]

@VipinLJ I respectfully disagree. Per Car and Driver "The xDrive system does provide excellent traction under acceleration and ensures easy and repeatable 5.2-second runs to 60 mph. The quarter-mile kept coming up in 13.9 seconds at 100 mph". Granted my timing is by no means official, it seems to fall in line with expectations. BMW wouldn't claim a time that the car can't perform as that would possibly open the company up to litigation.

@VipinLJ
I meant a map that Was designed for me to use more boost. I'm on jb+ with 91 octane since my fuel in California is pretty bad. With jb4, Map 4 can be used with e85 and my 91 octane to allow my car to target a higher psi. Unfortunately I couldn't use map4 without e85.

bquatt
They just have to claim a time they can be performed on prepped surfaces and often times with a rolling start. Many manufacturers do this. You think the Dodge Demon can get 2.1 0-60 without being on a dragstrip and slicks? Thankfully BMW is often on the side of caution and under reports what their Performance cars can do. Unfortunately though, it is a pretty wide known fact that bmw's speedometers run fast. Been the case on their cars for years, that's just how they send them out, but maybe your car is unique.

Still i personally think 5.1 is a little quick, and its hard to calculate with a stopwatch as i said, so I recommend getting a dragy. But ultimately it doesn't really matter as long as you enjoy the car. They are fun to drive!

@Dinan_Engineering your thoughts?

I understand what you're saying. But no one can sue BMW because their cars don't do claimed times (I'd be the first to sue them if that was possible). Like JT said, they probably did it on a prepped surface with excellent tyres and perfect weather conditions.
And it is a fact that magazines and review channels get cars with a little more oomph for testing. I've spoken to many journalists, both in NA as well as Europe and Asia and they all say the same thing. That their test cars usually perform better than non-test cars. And BMW isn't the only one that does that. Almost all manufacturers do. One may ask. If that's the case, how do we trust magazines and reviews? Isn't the manufacturer/magazine misleading the general population? Why aren't they being sued? I honestly don't know the answers to those questions.
Again. Irrespective of what our stock cars do, they're fun cars. Numbers are nice but the driving experience is what is better. And if you think I'm wrong, that is okay too. As long as you're happy with the car and performance boost and numbers, that's all that matters.

Ah yes. I understand. I'm guessing you probably can't use map 3 either without E85? I think map 2 is probably as far as you can go with 91. Map 4 is also tamer than map 3. It might be possible to do a map 6 with your 91+E85.

[JTYAMSHAYIN]

@VipinLJ Yup you're spot on! Im able to run map 3 and 4 but would need E85 with anything above Map 2. I'm thinking my best bet would be something along the lines of what you did and keep logs till i can get a custom map for 6.

Yup. Get logs on map 2, 3 and 4. Once those logs look good, octane permitting, a custom map 6 should be possible. Sucks that you don't get 93 octane fuel there. That would've helped a lot.

@VipinLJ you're correct Vipin, tenths of a second don't validate or invalidate the "fun factor" of a car.

Absolutely not. I had an A4 that was quicker stock for stock. But the 330i makes me smile every single time I drive it!

[JTYAMSHAYIN]

So took the leap last night and bought a JB4, was hoping someone would crack the 2020-2021 models so we could use BM3 but have a feeling it's going to be a while.

Anyways @Mike@x-ph.com was helpful and so were the people at Burger Tuning. Strangely though Burger no longer ships to California, even though they are located Cali? So I had to purchase from X-PH and they will have to be the middle man so I can receive it. I'm no way in a hurry to receive so no complaints, just thought the situation was strange.

Dinan cracked the DME. Their flash's should be available any week now. Granted you would need a bench tune.
