Default map switching

I'm finishing a custom MSS54HP software to allow multiple tune switching on the fly. Looks like there's enough space for 6 or 7 tunes.

Tune switching is done through cruise control buttons with indication of current tune through RPM readout. Resume button is configured to always go to a pre-selected tune for as long as the button is pressed, reverting to the previous tune on release.

Cruise control functionality is retained.

Awesome. I wish I had your software skills lol. Maybe instead of the RPM readout, the oil temp/shift light LEDs would make more sense.

Other idea would be the upgraded wiper switch stalk to the one that an the extra button on the end. Of course that's only if the cruise control button causes any issues.

Awesome stuff though!! Do you actually have 6 or 7 different tunes?

Wtf??? So I assume you added in your own entire code to do this


This is incredible.

This would be a great way to add a "valet" tune. 3000rpm redline lol

Yup - 258 bytes of hand written assembly



Debugging was a ***** !

I'm thinking more of a low boost/high boost setup, fuel conservation/full power mode for race cars, E85 etc.

Default Re: map switching

So are you loading the "important" maps into RAM and switching those on the fly? Or are you able to load multiple versions of the entire 64k?

Are their any failsafes implemented? Allowing the maps to only be switched while v = 0 or something like that?

Did you ever mind to write the code in C and let IDA assemble it for you? Just search for the ME7 DME, these guys did it also with custom antilag procedures etc.

I can't begin to describe how huge a development this is, and right on the heels of the CSL software swap on default bootloader as well as pseudocounter flash clearing.

This is almost a surreal development, paving the way for new advancements and features that are light years beyond the current status quo!



P.S. in for crippled mode as a parked security device (lol) as well as my highly coveted pit row velocity limiter (also lol @ the ridiculousness of how badly I [don't] need this)
