very interesting.. this is a great if it works.. i wouldnt expect it to be as great the ems though but hopefully it will be close

3min3m2

Yeah someone let us know!!!

cburglb34

good news and bad news..

good news...it works...


BAD... CEL for knock sensor low input or something like that which sent me into limp mode

now that we know its possible someone try please to figure out if u can put a resistor in place and make this cel not come up

^ you gotta pay to play...

ElevationTC

Uhmm try using a diode! Diode isolote away from the knock sensor wire!

cburglb34

please explain more in detail.....

is the low reading to the ecu being caused by interfernce from the fic?

and please explain how to run it more in detail possibly a diagram...

i cant test it again for another week i am redoing my charge pipes


btw my readings at idle was .41-.42v and then i believe while in partial throttle it was reading .24v

ElevationTC

Hmm on the standalone it usually reads 0 unless there is something.. You sure u tapped the right wire? I have yet to try it so i dunno

cburglb34

it was the the knock sensor wire, and it could be readin .41 just cuz its not the most healthiest motor? idk i mean i have a slight knock at idle but thats been there for over 15k miles boosted and sprayed so im pretty sure things are decent...no shavings in oil ever niether

ElevationTC

"knock" , "det" Is different then valve tap, or rod knock, or piston slap...

If u showing this knock voltage. It could be interferice or something from fic..

It needs to be diode isolated. Tommrow when im not so tired ill draw a diagram!

cburglb34

ok thanks mike, diode makes it so that current flows only one way right? so i would aim it toward the analog a input right?

and wouldnt rodknock or piston slap show up on knock sensor?

3min3m2

Not necessarily. knock in this case detonation. rod "knock" would be better defined as a clunk.

cburglb34

i know the difference but the knock sensor is a microphone and i just thought it wold pick up those sounds

3min3m2

To my knowledge it picks up the actual vibrations of the motor. I'm not an expert, but thats what i know. I'm assuming the rod knock would produce sound waves, while the detonation would produce more of a vibration in the motor.

But, it still might pick up both...

Was this ever tested with the diode? Just curious...

TCpete

mike your way to bored lol... go make some mtuned shirts and stickers already lol

TCpete

oh and pls pls pls CALL ME ASAP

I NEED TO HEAR YOU SAY THIS ASAP TO DELIVER OPTIMAL LULZ TODAY!!!

cburglb34

ill get around to testing with a diode when i feel like going back and splicing my harness...AGAIN! its cold out so itll be a while

TCpete

in.. because tonight ill be rechecking this

paul_dezod

So what was the end result of this Mike?
