Dinan Stage 1 vs BMS Vbox comparison 1/4 mile /60-130

[F12M6MD]

Yeah boots I was keeping up with your M5 if not a slight bit faster on that pull we did. Fun times. My M6 has no tune with cat-back Meisterschaft.

[boots]

Yep. Some cars are just fast and yours is def fast!

A lot of good info here. Thank you for taking the time to test, document and do a write up.
I have been a loyal fan of BMS as it gave me exactly what I needed and expected. I've been consistently trapping in the 128-129 mph range and I believe I am the only m5 in the 160 mph range for 1/2 mile as of last weekend. My trap was 160.7 mph and the fastest M6 with same mods was 160.3 mph. We have also done 3rd gear pull against another m6 with Dinan's piggyback with me being a fender ahead by the end of 4th gear. Our cars are pretty inconsistent and weather/humidity plays a big role in testing. The best thing you can do is take it to the 1/4 mile track with two setups, two same cars and get your traps there.

great info makes me ponder about switching to Dinan.

Since I raced spinny on Sunday although he has a cp car I still believe the dinan is a more complete package.

The Dinan setup makes the car much much more consistent, and the change in DCT function makes the car significantly quicker. Like I said despite traction issues with the Dinan at the top of second gear I still had the fastest 50-70mph I have ever tested on my car with it ( 1.3 flat) in worse conditions than BMS tests. The throttle modulation and top end power increase with the return of instant DCT shifts makes it a more rewarding experience daily driving as well. Looking forward to the bump from stage 2 as well, but will test again this weekend when conditions are more equal to my last BMS test . I know it had more in it, just have to find the optimal shift points again. My half mile traps are limited by my ECU at 158.x no matter which tune I run on a 0 slope road anyway, but the Dinan gets there faster. I'd put my car up against anyones head to head same fuel same tire, same track .

I am in to see the race between NC and SC. Hold on guys, let me get some popcorn.

The DA was 580 for the Dinan test and 100 for the BMS runs , so the BMS got slightly better air, both cars had a full tank of 93 octane . I think the acceleration graphs clearly shows the difference between a proper tune and not , especially on the shifts. Traction was more of an issue with the Dinan stage 1 due to it making more power on the top of 1st gear and 2nd gear as well as an instant 1/2 shift, you can see on my 1/4 run were i had to lift at the 1/2 with the Dinan for a moment. It def has more in it, on the 60-130 as well.The first 3 are the Dinan runs.

Thanks GMD. We both supported BMS like crazy, and its great to see someone actually get out and show all sides of the story

Probably helped BMS guys get better firmware with all this info.

Congrats to dinan for making a good solid product even if it is 4 times+ the price lol

The fastest verified BMS trap I have was equal to the Dinan both 128.x mph with 130-131 terminal velocity. The Dinan and BMS are essentially equal , the BMS was faster on one 60-130 run on a better day air wise but as you can see was the same on another at 7.5. Within .2 seconds can be shift point traction in 2nd etc. etc. . The Dinan has more in it as I was having traction issues with it at the top of second gear (It def makes more power up top than the BMS, while the BMS made more around 3k). On pump gas the two are equal with the Dinan having much better transmission function and responsiveness. The Dinan 50-70 mph was almost .2 seconds faster due to a faster 2-3 shift leading to a faster ET. Both also had the same 157.x , 1/2 mile traps, so power wise I think they are essentially the same . My fastest terminal speed was 127 (125.x trap )stock but that was on a -2000 DA day while both these were on a positive DA +100 BMS/ +580 dinan) .
Your'e right I can't be sure what is causing the long shifts and power delay on the runs since i wasn't logging data this time ,but obviously the car wasn't liking something with every shift at +3.5. Also at the drag strip it kept having a weird hesitation in 1st when i attempted to modulate the throttle then a huge delay on the 1-2 shift. I'm sure the new firmware with the slower tq ramp up will help alleviate this some .

Great info! Great post! Not sure having more torque in 1st and 2nd is a desirable thing. As you know you don't spin to win. Actually Terry has an new option for the S63tu for less torque and a smoother curve in the lower gears for better control and feel.
I think these findings are really good for Dinan, but I still don't see a large enough delta to warrant their asking price for their tune. IF they had a legit tune, I'd shut up, and pay up.

You have to drive a Dinan car to believe how much better it is than the BMS driveabilty wise . It makes more Hp in 1st and 2nd not more Tq by holding a modest tw increase longer . It is a real piggyback tune with full dual ECU control . Unless BMS comes out with a JB4 for the TU no firmware updates will help . In the end it's limited to altering TMap sensor data and that's all it can do . It makes power but there are too many situations where it's compromises outweigh its benefits .

Im not much of launcher so 60 to 130 is really more intereting to me personally and thus far bms is still ahead by your data and other cars in the low 7s. My BMS car drives as well as stock except with 110 more wheel hp on pump gas
Do you have any dyno figures?

I'm going to run again this weekend when the DA should be equal to that BMS 7.36 run . 60-130 is highly dependent on conditions, even more so than trap speed . I have plenty of BMS runs in the high 7's that were slower than the DInan too . Remember most of those BMS low sevens are on race gas and almost 3 degrees downslope . My runs are dead flat . But I absolutely think power wise the stage 1 DINAN and the BMS set to 3.5 are close . We will see what the stage 2 software does when I get that . I have no interest in a dyno number, they are like $&& holes everybody has one lol . The real difference is in drivetrain integration , DCT performance and safety . Like I said I didn't believe it until I drove it , the better power up top vs the midrange and better DCT function makes the car much more fun .

My 7.4 run with bms was with 93 and .01% slope lol. I really want to get a ride in a dinan car, anyone Local to philly have dinan one?

What was the DA, like I said before our cars are very sensitive to IAT's . I stand by my assessment that in a dig or roll race the Dinan would be quicker though because of better drivetrain response . Once the BMS is at full boost and adapted like a 60-130 they feel and are about equal until gear shifts .

positive 6XX something i don't remember the exact number. i haven't had a chance to run in negative DA yet but maybe i will get up really early this weekend and try at 3 am. Hopefully i get my car back friday and see how the KW coil-overs feel as well.

Cool . I've done a lot of 60-130 testing and it's amazing how much variation there is based on just shift points and DA . It's really not as easy as people think to get the most out of you're car .

i totally agree man especially with all the tq our cars make its hard to put it down at times.

I couldn't agree more! I had a bitch of time getting the DCT to do what I wanted at the roll race at Pocono back in July. I miss my 6 speed manual for that.

Attached. I am sure one of these days @boots and I can dyno on the same machine on the same day.
