BM3 OTS Stage 2 M3 - 100-200kmh 6.8!

[Shortyy]

Hey lads.

Finally had a play with my M3 this week, my car is a 2017 M3 Comp LCI.

Only mods are decat downpipes and K&N drop in filters. I flashed BM3 stage 2 OTS 93 file to run with my UK 99 Ron fuel.

Went out to test last night on dragy and pulled 100-200kmh in 6.8 seconds easily and consistently, the thing is a missile! Really really impressed with the map, it’s so smooth but brutal at the same time.

I known theres other stock turbo cars running quicker but I thought this shows how good the BM3 OTS files are to be running 6’s easily on pump fuel and so little mods.

Hats off to Halim and the BM3 crew for making an awesome flashing tool and maps. Next up I’ll try the E30 file and then hopefully a custom tune after that.

That’s a serious time! Looking forward to your E30 run. I have to get this dragy timer tool!

This is prob OTS MAP record!

[whoop_ass]

at First I thought it was downhill, very nice!!!

damn fast for little mods.

Cheers lads. I think it could go 6.7 on a perfect run but that’s about it for the current set up.

What times do other people run on the OTS stage 2 file? Would be good to see more times

That's very fast for OTS!
What was the ambient temperature?

What was your ambient temps and humidity / DA for that run?

My best in our summer weather 75-89F and 85-95% humidity has been
(100-200) full tank in all the runs as I expect better times with less fuel which I'll try soon.
*Stock car but charcoal delete*

STG1 93oct(98ron) 7.42s +0.06% slope 85F
STG2 E30 7.06s +0.10% slope 85F

-Custom Maps Full Tank of Gas-
HCP E40 6.72s +0.14% slope 80F (26C)
HCP E60 STG2 6.38 +0.0% slope
F80Paul Custom STG1+ Full E85 6.17s -0.15% slope 70F (21 C)


** under 21C half tank or 1/4 **
pending

Ambient temps were around 9-10 degrees celcius so nice and cold, it’s getting to winter here now now. Also running 1/4 of a tank of fuel.

Who tuned your custom stage 1 E85 file? These cars are so fast with ethanol, I wish we got it at the pump in the UK and I’d run it all the time. I have to buy my E from a company at around £2 per litre! I’ll try to get out again this week for more runs if the weather is good.

Solid time

[chewbakam4]

Can’t put power down this morning on the 93 map. I need my winter tires on. I wonder if winters will slow the car down much or it’ll be quicker due to more traction.

Excellent results Shortty ! As long as you're not traction limited the E30 map will shave that time down even further.

Nice

I had 6.7-6.9 on the stage 1 91ACN and with the E30, I did 6.4 (downhill) but 6.5-6.6 sec average all night

Here's my E30 OTS no mods with 3/4 tank
60F ambient but 80% humidity & 1500+ DA
IAT were 78F beginning of pull & 86F at end to take in consideration weather plays huge roll.

7.85s 60-130
6.76s 100-200

Good effort, as you said the conditions don’t help you but that’s a still a solid time. Is there a nice difference between stage 2 OTS sand E30 OTS?

Yea there's definitely is.
Downpipes + E30 OTS I'm seeing its running 7.45 with more negative slope
My car is still stock cats, I think you will see improvement overall

I've tested in real world roll-racing too
