I am far from an expert on tuning with the factory ECU, in fact I would consider myself functionally impaired on the topic. However, I do understand that many people experience problems with the factory knock detection after they re-do their 2.0 Liter 4G63 with forged pistons/rods, or go with a 2.3 stroker kit, or go with a 2.4 4G64 block. What have people done in order to accurately detect detonation on these types of modified blocks (when using the factory ECU)? When going to a radically different type of block configuration (i.e. 2.4 4G64 stroker, or 2.1 destroker) should one just abandon all hope of having reliable and accurate knock detection via the factory ECU?

 

i run a bosh knock sensor but it doesn't work with the factory ecu

 

go into the ecuflash forum, all your answers are in there. knock control is completely tunable on the stock ecu with fantastic results
