Yes it was the case of trying to have more information is all. This year, the engine is up from 2.5L to 3.0L and a more aggressive cam. Figured maybe add in the knock sensor input. But can keep using past method ... but maybe some fuel additive this year for higher boost testing.vlad01 wrote:I found the factory knock control system very hit and miss like Antus said, it's very early and primitive.
I find most of the time it triggers from gearbox noise and exhaust pulses when you have headers. And the worst part is, most of the time it doesn't even register real knock when I verified with knock headphones on the dyno.
I disable all settings related to knock and just tune in a little safety margin in the spark table with knock headphones.
If you want knock control it may be possible to run a external knock box like the G4 that HP academy showed years ago into one of the inputs and run a flex table to retard the timing but I think it will still be crude compared to modern ECUs
