Interesting.. though those seem like relatively trivial advantages considering the exponential increase in stress as rpm's increase.

Tach can not change higher up there. It's not variable at the top. Even the dynamic redline can not go below 4500RPM wihout creating a whitespace at 8K
I have set my redline at 3000 rpm until the car is completely warm, thinking about adding red so it stays uniformly red from 3K to 8300 where the static red is. Here is a video I took earlier today at the lowest stock level before the white begins to show: Edit: going to take a quick video for you guys..

Just FYI, you guys can check the RPM on the cluster in digital format. I'll try to post the steps later today if I have some free time.

Quoted from another thread, how to access hidden menu, actual revs is under menu item 7.2:

The only good ones to use are menu 2 (cluster test) and 7.1 I believe is coolant temp in C, 7.2 RPM, and 7.3 kph (this is off the top of my head, it's the same as my E46 was back in 2003), except instead of just going to function 19 to unlock, they made it a calculation of the vin #.

There is also a byte that refers to rpm buffer. All of this combined lets you hit 8,450 ish with a stock car (especially with DCT).

I've changed it to 4,500 until I open the cluster and extend the red to be able to go down below 4,500. Top screenshot is stock, bottom is with my current changes. The way to properly read it is between -25C and 0C the RPM will raise from 5000 RPM to 5000RPM 0 and 25C the RPM will raise from 6000 RPM to 6500. (Now keep in mind that 25 Celsius is 77 Fahrenheit, so this is the section that most people will be in depending on their climate - this is why people in California have a 6500 RPM limit upon cold start). Then once coolant temp reaches 50 Celsius (122F) the RPM is raised to 7000, and finally to 8,300 at 80 Celsius. Keep in mind the ECU uses an interpolation function and will seek out the midpoint between two points to use as the actual value. With my changes, it stays at 4500 RPM and raises slowly. So at 60 Celsius 5500 RPM becomes available, and at 80 Celsius the full redline is available. I would say that normal operating temperature is between 90 and 100 Celsius. I have another video of this in action if you want to see it.

Appreciate the detailed explanation. Is this offered as one of your coding options? |
