tune

has anyone done the Dinan stage 1 tune to their m850i ? numbers look great, but I'd like some one to tell me if it works before I pull the trigger.

Would love to know about this too. I have RaceChip reprogramming the GTS Black from my 2018 M5 for my new 850i.

I'm going DME also...GREAT service by these guys, awesome gains.
As far as Carbahn, their tune looks great but trying to deal these guys made me choose another tuner. I emailed the Carbahn BMW installer in IL asking what the process is, as I live about 5 hours away. He responded with "we need the last 5 of your VIN to see if it can be done thru the OBD or sent to Carbahn". I replied with the VIN March 4 and still no response. I then on March 9 I made contact with the GM Chris at Carbahn asking if my VIN was compatible with an OBD flash or if I could send him the DME directly. His response was "it can be done at one of our dealers or you can send us the DME". I followed up asking the process in getting him the DME, turn around time, etc. No response. I am willing to drive 5 hours and spend $2500, you would think they would be a little more responsive. So now I'm using DME Tuning, they do remote tuning thru the OBD port. Claiming 100+hp/tq.

I'm running 729bhp on my M850i thanks to a custom tune from a company here in the UK.

I'm running 990hp to the driver's-side front wheel and 850hp to the others. The car's turn-in is exceptional.

My sarcasm aside: quoting power numbers without supporting data is a bit empty. Do you have any resulting performance numbers say from a Dragy or the like?

Is the 729 wheel HP or crank? Whose dyno? What fuel?

I know, I know... it's like the Spanish inquisition but it's the only way to extract anything meaningful.

For example: my 2019 M5 put down 720hp to all 4-wheels and 740 ft Ibs of torque which ran 0-60 in 2.77s and the 1/4 mile in 10.6 if memory serves. I then got a 2020 M5 Comp which was a fair bit faster and, on pump gas that's very similar to your own, she ran 0-60 in 2.57s and the 1/4 mile in 10.33s on a farm road. I'd extrapolate the 2020 M5 was making 750ish hp to the wheels and a little more torque which is very roughly 850 crank hp using a conservative 12-13% drivetrain loss. The dyno was a Mustang all-wheel dyno.

Do they quote any performance numbers as opposed to power gains?

I hear good things about these tunes especially combined with bolt-ons. However, I can't find a single DME-tune-only car on Dragy's leaderboard that beats JB4-only cars. I personally ran 10.33 on a farm road. Of course, Dragy isn't the only source of data but it sure covers a lot of cars worldwide. So if you're not considering engine bolt-ons or exhaust mods, then perhaps a piggy is for you.

Just a thought...

I did Carbahn (Steve Dinan's current company) Stage 1, which gives you ~750 bhp @ 91 octane, 774 bhp @ 93 octane and ~800 bhp @ 96 octane. The difference is huge, I can recommend it.

Also change the air filter to a low resistance one.

My 2019 M5 had 720hp and 740 ft Ibs to the wheels per a Mustang all-wheel dyno—that's well over 800 on both hp and torque at the crank. My M8 is substantially faster than that car with the same tune (just a JB4, nothing else) so presumably it would dyno even higher on the hp front. But neither you nor anyone else can determine if that's more power than the Dinan tune because we have no common denominator—that's where performance numbers (or even dynos under strict conditions) come in. Do you have any performance data from say a Dragy?

My 2020 M5 Competition hit 60 repeatedly in 2.57s and ran the 1/4 mile on a farm road with pump gas in 10.3s.

We all love the big power figures (me included) but there are scam artists out there now making bold claims (think lying) about their power gains (I'm not referring to Steve Dinan in any guise here) hence these now easily-attainable real-world performance numbers provide us with a common frame of reference which helps everyone get the best bang for their buck.

I like the idea of the top speed limit removed. 150 is fast but it's not 200+.

also the power boost, but anything can give me that. So far only Steve Dinin seems to be able to remove the govenor.

Agreed--no piggy can do that. I'd definitely consider that a plus.

Precisely, so pick the one with the best perf gains... not arbitrary, apples-to-oranges hp/torque claims.

Well, guv'na (as we limeys like to say), I don't think that's true-> if memory serves, many of the ECU-tune vendors have cracked removing the top speed governor (Evolve, for example).

Ah, good point, I don't know--I think that's still classified as the N63 engine variant. I know most have cracked it for the S63TU but that obviously doesn't help you.

I put a photo of the dyno run info here, done at my tuners DMS Automotive - https://f92.bimmerpost.com/forums/sh...php?p=25822269

In terms of a drag strip, I was meant to be doing a speed-run on 21st April, but the event has been called off due to Covid-19.

In terms of fuel, it was running 95 RON, so the 'cheap stuff' we get in the UK - with 99 RON it will likely be far more.

Nice--the numbers look great! Dyno numbers just can't be compared easily so they have little meaning to me.

Totally understand on the speed-run.

I'm British and understand your petrol predicament. Mine is only a little better here in WA where I get 92 US which translates to ~96 RON.

I look forward to the speed runs--you're gonna be impressed beyond belief I suspect.

There is quite a few 60-130 F90 M5's I know one of the guys did 9.89 1/4 mile and I believe under 6 seconds 60-130 on draggy.

Ill fool around with my cousins F90 this weekend with the draggy, hes running DME Stage 2 and catless downpipes only.

Yeah, that's my buddy, Hockeytyme--I've driven his F90 and it's a very special car (he's driven my M8... in fact, he even lost it briefly). I don't think he's run under 6s for the 60-130. That said, his car isn't a good baseline--way more mods.

Let us know what you get... g'luck.

Will do, there was someone out on the east coast running under 6 seconds. Ill even do my M8 was hoping to race a few people here locally on "dig night" lol.. I'll keep you posted.
