Yup. There aren't any numbers for tuned G20 330is/330es online. Lots for the M340i. You'll probably be the first to post acceleration numbers (there are lots of Dyno numbers online but, to me, those mean nothing).

Did a few more 100-200 kph "runs", this time with a rolling start from 85/90 km/h. Everything else the same. Sport Xtraboost mode, ESC in Traction and transmission in S mode. No modifications.

Best time
100-200 km/h: 15,65s (corrected to inclination 15,51s)

As expected, the 10s of Xtraboost used from the top has a significant effect on the time. Last time I had measured from a 0-200 run, so the xtraboost was mostly used in the beginning of the run and had less effect in the 100-200 range. A rolling start is a little more representative of real world usage.

Very good numbers!!! Is your tuning box still stuck in Netherlands? I can't wait for you to get it

Yes, I'm still waiting

I think Brexit and the covid vaccine supply chain are affecting a lot of orders in Europe. My Dragy took 3 weeks to arrive, and I know a lot of people with delayed orders, some by almost two months.

I can't wait to test it out, specially after these stock numbers

Yes true. Hopefully you get it soon! It'll be worth the wait though I've posted my dragy numbers in my JB4 thread. My G20 is the slowest stock 330i on the planet!

How exactly does a custom map work on JB4? Is the programmer just increasing boost above preset map parameters?

You can set boost as well as other parameters. What parameters? Well. I'm not the right person to ask. I'll post a pic of the user adjustment page below so you can see what parameters can be adjusted. He sends me new numbers to try and then I go get a couple of logs and send it for him to check it out. We then adjust accordingly (with the latest numbers, I have to drop boost a bit since fuel trims are high).

I'm not looking at having the fastest stage 1 G20 around. I prefer driveability and reliability along with speed. Even with the map I was running before, the car felt good and not strained. It actual felt very smooth, like it was a proper tune and not a piggy back (if you get what I mean). Even if that means 0.1s or even 0.2s drop in quarter mile times, it doesn't matter (worst I ever got with that map was 13.17s which, in my eyes, is still pretty damn good).

[VipinLJ]

Terry@BMS took a look at my logs and tweaked it a bit more. Updated map 6 with the changes he suggested and damn. The car feels like a completely stock car now! Just faster. Also, broke all my old personal records with this car today.

I'm indebted to Knifeedge2k1, Turboh, Terry and the others who've helped me tweak this car!

For reference, my best stock times were:

1. 0-60 - 5.98s
2. 1/4th mile - 14.23s@97.28mph
3. 0-100 - 15.06s
4. 62-124 - 19.83s

All runs were done on the same closed road with zero traffic. Literally, an abandoned road leading to a dead end (before anyone decided to question the safety of these runs).

Also, this is a stage 1 car (my only mods are a JB4 and some E85 mixed with 93aki to get an approx E25 mixture).

Trap speed at the quarter mile today was 107.50mph!

These results are seriously awesome. I'm more and more leaning to get a JB4 after I test the 330i with the JB+ for a few months. The support with custom maps seems worth it alone and even though I'm limited to 91 octane I imagine the fellas at BMS could work something out.

Oh yes. And those numbers were tested right after I changed the values and with snow flurries. I'm sure it'll become better once I drive the car around for a bit for it to learn and the weather clears up. Even if it doesn't, for a stage 1-, those numbers are excellent.

Your handicap will be 91octane. I run 93 mixed with E85 (approx E25). I also have the EWG connector. Am I happy? Let's put it this way. Our A7 is a 2017. Our SQ5 is a 2018. Our 330i is a 2020. I have more miles on the 330i than on either of those two cars.

Haha. It isn't bad at all. Did a 100-200 run today and it was at 12.91s with a +0.6% incline. The worst quarter mile time I got with the latest numbers is 13.06s@106.xx mph (dragy is on my phone and I can't remember the exact trap speed off the top of my head). This was also with a positive inclination (again, can't remember the value). But yes. I'm enjoying it. And logs looked healthy. We're still tinkering with it. I'll keep the thread updates with my findings.

That is really fast!!

What hp gain do you estimate with those times compared to stock?

I've only used virtual dyno (it's good for a before and after comparison). I haven't found a 4wd dyno around where I live (closest is like 2 hrs away and they want $300 for 2 pulls)! With VD, my stock numbers were 225whp and 246wlbft. With the latest numbers, it says 290.7whp and 308.6wlbft. I've had the hp and torque go as high as 304whp and 327wlbft on a different run with same numbers and settings but I won't believe that (300whp is a little too much with just a piggyback!).

Upped boost by 0.5psi from 4000-5000 RPMs.

All other conditions the same. Same road as well (as all my other tests).

Apparently we can still increase the boost across the rev range. Haven't done that yet though.

4.75 0-60 is pretty amazing. This is outdoing stock 335 and 340s of last gen f30's

[vTuga]

Those results blow my mind. Just proves this B48 engine is a beast.

What PSI is your car typically pushing across the rev range?

Oh yes. Those numbers are very very good for a stage 1-. Plus, my car was slow to begin with. My quarter mile times have improved by atleast one second (more in this case). The best part is how smooth the car feels. Both engine-wise as well as power delivery-wise.

Yes. It's a huge step up from the N20/26 engines. I've seen fully built N20/26s struggling to get to the 12.xxs range. If a simple piggy back and some good fuel can do this, imagine what a stage 2/3 car can do! Dronamashina's car is proof.

So we're running absolute numbers now. Not additive. Stock, my car boosts very low. Iirc max is only like 11psi (yes. It's only my car I believe. Other 330is boost higher). Right now, max boost is 20.6psi. Not sure if that's what the car produces though (since I'm not an expert on how the JB4 works (other than knowing the basics)). I'd say around 8-9psi over stock at most.

Coming from two previous tuned Audi S5's, and pleased with the results of the B48. Literally first and only quarter mile run log and so close to 12's. Only mods are JB4 (map 3), E30, Michelin Ps4's.

Your map 3 times are impressive! Best I've gotten with map 3 was 13.14s IIRC. But that was a one off. All other runs have been in the 13.2s range.

Is yours an xDrive or RWD? Also, what is your trap speed at the quarter mile? Do you have the EWG connector?
