If you homebrew a stage 3 setup on X, will XR work reasonably well for race gas?

Default If you homebrew a stage 3 setup on X, will XR work reasonably well for race gas?

Since the adaptation channels will affect both programs, once you have your 93 octane program sorted w/ Lemmi & ECUx shouldn't you be able to just switch between the 2 as if you were running K03s?

Or am I totally off base...and the fueling and timing differences won't translate well to the modified hardware setup (new injectors, MAF, turbos, MBC)? Could one be lucky and XR just "happen" to work well? Or is the only way to safely/effectively do it to just tune a separate 100 setup and lemmi the changes if you ever want to fill up on 100?

i think you have to do all the lemmi setting again if you change chip!

With K04 (and Hybrids) + Lemmi - Homebrew, XR will work just fine on 93/94...

Default Do you really get better timing tweaking from XR than X? My past research revealed

that there really wasn't much difference, and that it may also depend on the car. Do you have any data to show otherwise?

Default wasn't my question, but good info. CFs are still fine even in steamy summer weather?

Probably gonna depend on the boost you're running, too.

For flashloader, I don't think that's true.
