Multi-map dragy times?

MadToy · 02-03-2023, 12:51 PM

Working on my BM3 Multi-Map tune with flex fuel. Can't find much info on stage 1 results with Dragy or track times. Hoping to see some comparisons so I can see if I'm on the right track (pun intended)....

2018 340i Xdrive
Bootmod3 Multi-Map custom tune (E47 on this run)
TU HPFP
XhP stage 3
Everything else stock for now - including downpipe

Are those times with the factory Launch Control or "manual" LC technique and if the latter - in which gear?

Factory LC 1st gear. I let off the brake before it reaches 3k.

I had to tune some power out down low due to the 225 run flats :/

From memory LC never reaches 3000 rpm though?

Your times appear really good. Not afraid of braking anything on the drivetrain with drag runs from 0 and that power? Not suggesting you should necessarily be, but I am a bit

I think it would settle at about 2800. I'm letting go at about 2500.

Not too worried about breaking anything on the street with the runflats. The tires will lose traction before putting too much stress on the drive train.

Sticky tires on a prepped track might cause me a little more concern, but I can tune accordingly if needed.

My runflat 255+225 do not lose any traction on dry asphalt at OTS Stage 2, even with RON102 fuel….

I have crappy 225 Pirelli all seasons on all 4 😞

Zero reason to worry at anything near that power level.. at all

Skyhigh · 02-04-2023, 07:30 AM

And what would “that power level” be…?
It is much more about torque than about power…. Plus full weight vehicle (e.g. M140iX, even when fully speced is appreciably lighter than 440iX fully speced)

So what tune is this exactly?

I'd be really curious to see a full 1/4mile run with a log. Looks like solid numbers with a stock downpipe, very solid.

My goal was to make it as fast as my Tesla M3P with the stock downpipe. It's dead even now if I factor in the uphill slope.
I have a high flow cat on order just to see the difference.
Tuning the B58 is a bit different than when I tuned my N55. So many more load limit tables to find. Ma Buyun was a great help finding them

People have twisted their driveshafts at stage 1/2 maps, seems to happen often to RWD, but it does happen to AWD as well.

When I first looked at the draggy results, I saw 0-30 3.4 seconds and I was wondering how everyone was praising the numbers! But it was a clearly "read to the period" moment!

I ordered the MAD catted pipe.

5w20 · 02-13-2023, 08:17 PM

340i RWD
MRM 4.5” D/P to a custom turndown (no exhaust)
BM3 OTS Stg2+ (on multimap E69 w/flex sensor)
Fuel-it Stg2 HPFP
Rear seat removed
Passenger seat removed
Lightweight battery
17x9 Apex Arc8 with 275/40 Hoosier drag radials

Spun horribly, see orange graph showcasing huge dip in G-Force where I lifted on the throttle. Still was able to back half 26+ mph, so it is making some jam. 💪🏽
