Hi all i have had a problem with my evo 6 for a while now where it feels hesitant and low in power not all the time though ,,, so i bought evoscan + lead im new to this and was wondering if someone would take a look at my data log (i will try to attach it to this post) it looks like when the fault occurs the knock count go s up to 35 ish and it whacks the timing back to -5 also i got engine fault code 24 up by earthing pin 1 on the connector (vehicle speed sensor) would this be why i have no mph reading on evoscan the speedometer works fine though ,
also would this make the knock sensor more sensitive because it thinks the car is stationary or is my knock sensor goosed i dont think it is knocking as i have had it ecutek ed thanks in advance for looking ,,

give me your evo 6.... or sell it to me problem solved.

 

Ye really helpfull mate thanks a lot!! .

 

nah DTC 24-VSS will not be related, I get that code because I cut the vss wire at the ecu to ignore my JDM speed limiter and my speedometer still works.

but that knock sensor and knock filter is really pulling your timing! thats why its hesitant... it looks a little lean at the o2 sensor. but that could just be because you aren't yet at WOT, could be engine noise on the knock sensor.

If it was me.. I would use an oscilliscope or LMA-1 to record the actual knock voltages at the ecu.

 

What volt do you consider knock on the stock sensor? Mine will reach 1.4 just reving on idle... I'm reading through an aftermarket ECU. Don't know if its the Actual voltage, but i don't see why not.
