Resumen

¿Cómo configuro la detección y el control de detonaciones sin la detección de detonaciones por audio? ¿Podrías explicarme qué podría causar detonaciones falsas? Mi respuesta es que no recomiendo configurar el control de detonaciones sin la detección de detonaciones por audio. Sé que requerirá una inversión considerable en equipo de detección de detonaciones.

00:00 - How do I go about configuring knock detection, knock control without audio knock detection? Can you tell me everything that could cause false knock? OK my answer to this is I would not recommend trying to set up knock control without audio knock detection.
00:16 I know it's going to require a bit of an outlay for knock detection equipment.
00:21 You can get this really cheaply these days, probably the cheapest that I've come across is the Tuner Nerd Knock Monitor.
00:28 Off the top of my head I think that product is somewhere around the $200 USD mark so you consider that sort of outlay versus the risk of damaging an engine which could be thousands of dollars, for me that's an absolute no brainer.
00:41 The reason I say that audio knock detection is really an essential step is we need to validate the knock control strategy that we're setting up.
00:50 In other words we're basically just telling the ECU where the noise floor is above which knock will be considered to be occurring.
00:59 So we're a little bit blind if we don't have a way of actually monitoring and knowing where knock is occurring.
01:06 We can't validate and know that the ECU is accurately detecting knock while ignoring background noise.
01:12 So that's my answer to that one.
01:14 What could cause false knock? A myriad of things really so in a factory engine management system, false knock, a factory engine management system already has a knock control strategy that is calibrated and tuned to the stock engine noise profile so when we modify the engine and fit forged pistons which have looser piston to cylinder wall clearances, they are basically going to be noisier in the block.
01:38 Likewise we also might have more valve train noise, maybe we've gone to a solid lifter compared to a factory hydaulic, basically all of these things will affect the mechanical noise profile of the engine and that can be enough in some instances to trip the factory knock control strategy.
01:54 In the aftermarket, with the likes of your Haltech, this will normally come from an improperly calibrated knock control strategy.
02:01 I must admit, I have not had the best of success with the Haltech Elite's knock control strategy, in my opinion it is probably not the most sophisticated in the aftermarket ECU world unfortunately.
