As you can see from my post here there is a VERY small gain in power (10hp peak) going from 95RON to 98RON octane. Two octane points is optimistic on one bottle of booster...

Yeah you are right but according to the claim done by most of the boosters is around 8-10 full numbers. ( not points )
Secondly i drive my car only on weekends. So a full tank lasts many months. I dont think it would hurt my wallet too much

I believe mine are dual CM10 from Burger Motorsport so spraying quite a lot. Pressure also drop quite a bit with such big nozzles. But probably spraying +70hp worth of 100% meth...

Regarding you believe in octane booster... 10 full octane numbers sound like snake oil to me. My source.

2 cm10 nozzles equal 2000ml/min meth flow. That should be 70hp 😁

Two cm10 nozzles according to the chart is for 900hp plus vehicles. ( just FYI )

Kindly have a look sir.
There was a total jump of 8-9 octane rating with 60:1 pump gas to boostane ratio.

The F chassis has a 15 gallon tank. That means you're going to need almost a full gallon of boostane to reach those numbers for each tank of fuel.

According to my calculations 1 full tank with 1 can of boostane will bring you around 102 octane. 1 bottle is for 30usd. Not bad i guess
Let me just get this wastegate calibration done, than i,ll keep you all posted with updates. I have a few bottles in my garage for the upcoming experiments

I edited my post. I wrote wrong. Corrected now

100% methanol in your WMI. Try to run that and take a log. I think that will solve our octane issue and also cool enough.

Boostane professional should raise your octane about that amount if you are running high concentrations (about a bottle per tank), according to the mix chart on their bottle, which generally seems to be pretty accurate. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

But i agree WMI is a better solution if you already have it installed

Correct. I am injecting huge amounts but I also use it instead of PI for volume and not only for octane. Been running it like this for 6 years. First with JB4 and now with a Torqbyte controller.

I took the car to dealership.
The wastegate was fine.
These errors showed up. They said to replace the DME.
Please help
I dont think the DME is faulty. I even dont have a check engine light.
Is there any way to reset the DME?

Do you have an active hybrid model?

Yes sir

LA1Z24 · 11-15-2022, 01:44 PM

I wonder if the active hybrid has extra safetys in place due to the electric motor. And he has somehow tripped those safety events.

What should i do now?
Any way to hard reset the DME ?

LA1Z24 · 11-15-2022, 05:08 PM

I have no idea. I am an auto tech by trade. BMW codes are very good at describing the problem at hand.

The first code is a tell for me. DME internal fault, Safety Function - Max total torque exceeded.

To me this says the DME has recognized a fault due to too much torque. And has shut down some type of operation due to this.

Is BM3 compatible with the active hybrid? Have you contacted BM3 about this? Play studid with them. Act like you're clueless and tell them BMW said it friend the DME. Maybe he can fix the DME

Yes bm3 does support activehybrids. Ok i,ll email them. Will get back to you soon.

Show them the list of codes from the dealer. The first code is probably what they will be most interested in.

You wrote that the DME has shut down some type of operation.
Does it mean a permanent damage or is it something else ?

The code description sounds permanent.
