i have a obd2a ecu and i have power,ground, illumination, ran correctly because it turns on and off with the key. when i went to hook up the rpm wire. i got a reading but it was jumping all over the place. the tack on the dash was working but the digital reading on the controller wouldnt read right. where is the right wire to splice into?

 

the trash can




seriously, it's 2013 why are you using a vtec controller?

 

because i have it. and remaping a ecu or anything like that is out of my league. and i dont have the money or time to send it off and have it done. im happy with the tune for now. all i would like to do is change where the vtec hits.

 

Well first you pull out your soldering iron, then you put your soldering iron back and throw your VTEC controller in the trash.

 

you realize that does absolutely nothing for you when you cant change corresponding fuel and ignition values, right?

 

no didnt know all that. so does anyone know what wire to tap into for the rpm signal

 

regardless since i already have it i would like the digital rpm display and shift light.

 

So nobody can tell me what wire is the correct rpm wire to tap into?

 

No one will help you because garbage.
