I called them today morning, they are in England.

They confirmed me will work I just buy it, will let you know the results.

Anybody knows about them?

Regards!

Any dyno sheets ?

[M5speed]

Awesome. Its great we wont have to wait forever to explore more of the cars capabilities.

After getting it set up under the hood and driving it a few miles, it is noticeably faster.

Have you logged AFR and boost ?

No. Ive been running 100 octane though and together with the tune, its incredible. The rear end almost broke loose on the highway at 80mph in 2wd mode over bumpy roads.

The car is beginning to outperform its driver I hate to say. Fun though nonetheless.

Ill get it to a dyno once I find one nearby.

Nice.

I'm curious to know the difference between this box vs Vivid racing which claims an increase of 147hp but it's double the price.

You have TDI,Manhart,JB4,Vivid.......not much real info out except for JB4 and it's not good info. 15:1 AFR, throttle closure, etc, etc is not a good sign that the new M5 will be piggy compatible. I've been waiting on RaceChip, but I hope no news isn't bad news.....

Track conditions were not good. It was near 85 degrees and 100% humidity. Hard to slow that bastard down! Barely had enough space to do it.

Need to take it back on a cooler day or at night.

Bmw claims 10.9@129 mph on stock car

I did 11 flat on stock car (on my first time)

This run is with tune?

Do you have a slip by any chance? Also what was your trap

Yes. Was having trouble getting into the ten second range obviously but then later realized I still have a speaker box mounted in the trunk that probably weighs a hundred pounds . My next mod will be getting that fucker out of there this afternoon! Probably explains a tenth of the time lost.

The car does its best when running cool and I had to drive an hour in the car before doing the runs which Im sure made it run hot.

I did adjust the tuning a bit with the controller near the track trying out different levels of tune which could have confused the ecu. Whats even more confusing is that I had 100 octane in the tank as well. Had about a half a tank. Last thing also could be that I have a wider set of HRE wheels. It has 11" rears and 10" fronts, comparing to the 10.5" and 9.5" standard set up, but the wheels should still be lighter.

I agree something doesn't stack up. Most tunes from what I recall have a specific program for running high octane gas and the tune seems temperamental, working way better when cool. Last thing was the track, which was trying to launch from an old track barely kept up with a half inch of caked up rubber on it everywhere.

I'd probably be better served getting a dash mounted timer and fucking around getting times on some country roads somewhere on a cool evening or morning.

That’s a GREAT time on an 85F day. The magazines correct their times to a cool sea level day. Yours is actual. Tell me where you were and I’ll calculate a rough DA. Was Launch Control working well for you ?

I was just reading about that. It was at Great Lakes Dragaway in Twin Lakes, Wisconsin. This was yesterday about 5-6pm.

Launch control did not work once. It had before, but this time no. Had it in all sport plus settings, traction control off.

I found this tool as well http://www.dragtimes.com/da-density-...calculator.php here's what it came up with -

Correct your ET and MPH using the DA (Beta Testing)

Extensively Modified Supercharged and Turbocharged Engines
11.003 @ 128.317 MPH

If thats right, you could subtract a tenth for the extra weight to be at 10.9. It would have been helpful probably if launch control would have worked, but even if it had, it usually wouldn't have worked consistently. Still seems slow, especially considering the high octane gas.

Twin Lakes... that's close where I live :-)
Planning to do exhaust/tune and down pipes and take it there too

GL track elevation is slightly over 700ft msl. But the DA was roughly 2600 feet. That’s an EASY 0.20 reduction and +2mph on a 0 DA night. That is being conservative. You are moving out.

I was thinking Id be blown away at the track after driving it the day before and noticing the difference with the tune. Getting it on a dyno would help tell a lot more.

How did you launch it ?

Same way as you would using launch control. Would launch around 2800 to 3000 rpms but I was getting too much wheel spin. I probably needed to back off it a bit to launch better.

Did you run fairly soon after arriving ? If so, the brakes should hold well when hot. If you let the car sit for 2 hours < then try a WOT launch, it creeps forward with cold brakes.

Problem was mostly launch control and me needing more time. Ten degrees weather difference would make a ton of difference.

In still not sold on this tune, however it did increase power a lot. Need to get it on a dyno to see real data on what its putting down.
