Ok so i have a customer driving up this weekend to get a tune and i wanted to use ELD to log the afr. I can do this in neptune by simple clicking an option box to tell the ecu to use the ELD switch. I want to use ELD because it allows the use of the full 5volt range and thus I dont have to scale the voltages on the wideband so the ecu can read it correctly.

I have asked a couple people who i thought would know the answer and to no avail I'm stuck at this point, lol.

Is there a separate plugin i have to install in order to use ELD? I KNOW it can be done because i have seen it done. I would just rather not use the o2 sensor as it decreases the range that the ecu can see.

 

are you talking about the electronic load detector? what does that have to do with logging o2. just disconnect the narrow o2 input to the ecu and feed the wideband 0-5v output into the ecu, crome will read it. and disable o2 and heat in crome.
