m i detonating? i m seeing 2.7V of knock on knock Volt in my AEM EMS is that normal? this was done by 4th gear pull from 80-115mph. thanks in advance.


ps: i have it log on my pc if anyone needs to see it. thanks again

 

anyone?

 

I would need to see the log file, but 2.7volt is pretty good knock spike IMHO, definatly not engine noise. I back down the timing if I see knock voltage jumping up above significantly over the line.

if you want to email me the file sales@diamondstarmotorsport.com, Id be glad to look it over and offer whatever help I can.

 

Sounds like det to me as well. When everything is going well I only see like .3V of noise popping up every so often. If I saw 2.7V I would think it is knock.

 

It really depends on the car. On a stock motor EVO I would say you are knocking. I have logged some noisy built motors where 2.7 wouldn't be knock. I don't think this is the case though. Some cars are louder than others. Check the noise curve and look for spikes.

Also, when you log, do so with the knock control turned on and pulling timing above your set voltage limit. Sometimes the logger will not pick up and display a noise spike, but it will always display pulled timing.

I'll allow a max of 2.5 volts after 6400rpm on my car.

 

thanks for the help guys, love the evom community... can get so much help here.
