Much like VE/AFR tables, it is important to first scale your axis correctly. Ideally, just match the VE tables axis. (You can copy and paste axis between by right clicking them).


Ignition timing, again without going too far into the aspect of advanced tuning, works in a fashion like this:

●        As RPM increases, ignition ADVANCES (Increases, the spark comes EARLIER in the cycle)

●        As LOAD increases, ignition is RETARDED (reduces, sparks LATER in the cycle.)


As a result, you can see a typical turbocharged engines map here (Running to 1.45 Bar of Boost, 245kPa):

As a rough guide, most engines will idle at around 10-20* of timing, so if you're simply trying to get the engine running, you could block change (select the cells and use the ‘=’ key) the entire top left area to 15*. It won't be anywhere near perfect, but for most engines, it's close enough before full tuning on a rolling road. The resultant map could look like this:

Tuning of ignition should always be carried out with caution, too much advance could cause serious knock and result in engine damage. Always use knock detection equipment where possible - for best results, use a rolling road or engine dyno to find the minimum required advance for the highest torque reading, typically discussed in books and online resources  as “MBT” or Minimum Best Torque/Timing.
