Modifying the rev limits per gear on the MSS5x DME
Credit goes to p0lar for this writeup.
Since the topic was recently discussed in another thread, and mentioned (more than once) how difficult it is to find information in the megathread, here's a quick howto on modifying the rev limits per gear on the MSS5x DME. The first thing to understand is where to find the configuration values for these variables within your DME. To do this, you MUST know what version your DME is. Please see this thread about how to make that determination. A typical map would look as follows: Quote:

The second '00 00 00 01 00 02 00 03 00 04 00 05 00 06 00 07' string denotes the gear in question and the third '1F 40 1F 40 1F 40 1F 40 1F 40 1F 40 1F 40 1F 40' string represents the speed (RPM) in hexadecimal representative to the gear above. To convert this to a more reasonable format: So, to modify a particular gear's engine speed limit in RPM, simply convert the desired RPM to hexadecimal and substitute in the string above. Here's an example to convert from the OEM 8000 RPM rev limit to 8100 RPM: Quote:
So, if you wanted to raise the rev limit to 8100 RPM in every gear, including neutral, you would recreate the original string as such: Quote:
