I wonder if is possible to implement a retard/advance table to the ignition table base on the gear that the car is running.
Stock Honda computers do this. I ask because I have recently experience the need to retard in higher gear because of knocking but as a result lost a little power in the lower gears.
something like;
1gear l 0
2gear l0
3gear l-1
4gear l-2
5gear l-3
etc
This should be enough we could use positive number to advance the base timing of the table negative number to retard and 0 to use the base timing number as is.
let me know what you think.

Re: Feature Request gear retard
The knocking is relative to load. Higher gears have higher loads so you can just retard your ignition table to avoid knock.
The only thing that changes in lower gears like 1st or 2nd is that you pass through these cells in the ing map faster so if your engine is not knocking then I guess you don't have the time to hear it. Retard these cells a bit and you should be fine..

I believe you can do this with with MS3 and table blending by gear.
MS3+X on 73 Karmann Ghia ignition only with LS2 truck coils firing in sequential, fuel next.

Re: Feature Request gear retard
The knock in high gear is the real problem.
You can change the time ignition on the base gear in MS3. You can use tableswitc-hardwrare-bland curve. In bland curve menù, select in axis x GEAR
