Under advanced tables. Does this mean if the car is set at around 20 degrees timing at 8000 rpm its actually more like 29 degrees?

i read that whole timing thread on crome but didnt really see the answer for the question...maybe i missed something?

The ECU adds a timing or "dwell" correction in the stock program as the revs increase...

This isnt ideal in an altered setup.

You shouldn't be concerned with the number, as long as you can get it to MBT. Thats where the least timing results in almost max power. Such as adding few deg more results in very little gains, or detonation. FYI the addition is essentially from Honda's stock code, so don't think it will advance timing to a crazy level.

Chris Harris

Eh...timing does change in different situations though, and if a change in IATs/ECTs...etc adds a little timing when you are already at MBT

Chris, have you heard of anyone actually testing how much Crome does or does not manipulate timing on the main tables?

I have an SSI-4 that I have been thinking of setting to monitor actual spark timing.
