BMS Stage 1 Same As Stock

[///F80M3]

I installed the BMS stage 1 for my f80 a week ago but for some reason I don't think it's on. I originally thought it was pulling harder but after running my friends stock m4 it proved otherwise. We did 40-110mph runs and he stayed right next to me every time and I did not pull away from him. Basically my car is running like stock.

How do I confirm the stage 1 is active and working correctly? If it's working correctly then I will just return it since its same as stock.

Every run I had with my friends stock m4 we were dead even and nobody pulled. I basically payed $380 for it to run like stock.

Has anyone else tested BMS stage 1 against stock?

I expected to pull at least half car length lol

I installed mine last week and for the most part it feels the same, I only feel a greater punch after 4k RPMs but it is noticeable on my butt dyno.

I'm not sure how you could test if the tune is working or not without doing some sort of quantitative measurement (dyno, 1/4 mile) unless you could somehow measure boost pressure

I didn't do any comparison tests but I just installed mine 2 days ago. At first it didn't feel like anything.. Until I went WOT in 3rd and my tail kicked out at 55mph lol. And doing WOT runs from 65mph.. It definitely pulls much harder than before.

I thought it pulled harder also but my friend said it felt the same when he drove it. Then I raced him but it was dead even. We were both in sport plus and mdm. I just wanted a little more power but it feels like I tuned my car for no reason.

You can log boost if u buy the cable but I don't know if I should waste more money at this point.

This worries me as I was gonna pull the trigger on a stage 1 since I most likely won't be getting downpipes. Hopefully one of the vendors can chime in on this.

40-50 WHP and WTQ should be somewhat noticeable. I was looking forward to this tune.

Stage1 adds 30-40hp peak. If one car starts a moment before the other, has slightly worse fuel, slightly warmer intake temps before the run, shifts more in the power band, happens to be lighter and more aerodynamic (m4 vs m3) then in a short race you might not notice a ton of difference. At least you won. All else being equal you'd probably of lost by a car in an identical situation on stock tuning. If you had a JB4 you could have changed maps up on the fly for an instant rematch at higher boost levels.

I noticed lag is amplified too.. It takes a split moment after you go WOT before it kicks in hard so your buddy probably got the jump on you then.

We were both in manual mode and same gear. Took off same time.

Do u think traction can be the issue? I was on mdm but I felt it cut off power on one of the runs between shifts. My friends car didn't have traction problem so he actually pulled ahead for a couple seconds.

I thought mdm would be better better than dsc on but I guess not.

Well thats exactly what it was.. If the car intervened and cut power no tune is going to help you When I track and have the nannies on, the power cut on the car is VERY significant and really kills your time when you loose traction.

I just put on RE-71s on the car and went wider so hoping that helps.

This tune sounds like a waste of coin..

Money is probably better invested in a different set of rubber

Should've just gotten the JB4 instead. Ran Map 2 on 93 and been happy. Stage 1 is a waste IMO.

Hey Mike I noticed on Burger's site it says the tune adds 50hp/60tq, which is different from the numbers you posted. Do you know which numbers are more representative?

For someone like me who wants a simpler install (so easier to take off when needed) and some improvement I don't see it as a waste. And if it really puts out 50 more horsepower and torque that's not insignificant.

Unless the product is mis-advertised or the product was not installed properly here (or the unit is not functioning), the bump in power and torque should be noticeable.

Look at it this way if jb4 didn't work it would be ahead in sales and have its own forum for that matter . I can attest jb4 does in fact work and stage one does as well. Maybe try uninstalling and reinstalling the unit and both of you have same settings on car before you race (MDM etc... Also having traction control would intervien with your car more so due to having more power where wheel break would occur more often causing the ecu being involved more so

We both had same settings and same gear. I just did a couple pull with traction control off and it felt the same so traction wasn't the issue. Also, just today i hit 120mph and shifting 4 to 5th gear the car started to hesitate at 6500rpm.

I bought the data cable so i will check if its applying +4lbs of boost. I should get it this week.

Do you need downpipes with map 2 on 93?

[salraf]

Timely topic for me as I was thinking about this mod as well. I know it is an engine tune but they should still make a substantial difference. I installed Stasis stage 1 to my prior Audi S4 and the change was huge. Granted to cost was a bit more substantial though..After reading this post, I may then sit this one out if there is no real change noted.

[ZAGA_M3]

I installed mine 2-3 weeks ago and i felt it right away.. Can hear turbos louder plus 2-3 on WOT loses traction.
It does work. Once you get the cable confirm and let us know
