Hi,

I'm quite new to tuning and recently I converted the slow MAF based ECM to a MAP based.

Is it normal/ok when I go WOT, The knock count is rises?

Attached the SA table and a xls log of few seconds. From 74% TPS through 100% and down to 29%.

What do you think?

Thanks

Are you using audio knock detection to validate what the ECU is telling you? If not then I'd recommend you do this first so you know if you're dealing with real knock.

The ignition table is quite possibly a little over advanced at low rpm and moderate load too so it's possible the engine is knocking.
