How do you go about this?
My current scales cover upto 5.6 but I'm seeing closer to 8 in logs taken today, so I really need to rectify this sooner rather than later.
Thanks in advance,
Zak

calvin.
your car must be bags of fun thenwhen I say nearer to 8 it actually peaked at 7.7
yes thats exactly it. all your tables are now going off the end of their scale and i'm not certain yet as to what the ECU does when this happens. does it scale further down or just apply the last column settings?but I'm still stuck with the scaling issue, and in particular what values I need to change in relation to your scaler example; are you saying I need to change the value of the load headings in each table?

you will need to rescale in the following maps:
- low detonation fuel map
- high detonation fuel map
- ignition base timing map
- ignition correction timing map
- vvt intake cam timing map
you should also set new limits to the following:
- fine ignition learning range (engine load)
- coarse ignition learning range (engine load)
- knock learning load thresholds
high rpm listening isnt too much of a neccessity but adjusting the load parameters is. peak cylinder pressure occurs at peak torque, this is also where you're most likely to get det so keep the ECU listening to the stock knock sensor incase you're running maps that are too aggressive. det at low rpm is the most damaging.What sorts of changes do people usually make to these? I've thought about tweaking mine for more high-RPM listening, but didn't want to end up with noise artifacts.
