I know this isnt the right section, but ive had this same post up in the tuning section for a couple days without 1 response, so i was hoping someone in here can help.


I have the 0-5v from my AEM uego going to E15. With the sensor unplugged, i adjust the voltage offset to match perfect.

It will log anything above 12.3ish/1.4vish (going off memory)fine, but anything under that, it will just stay at 12.3/1.4v even tho the gauge displays 10.0afr.

So i change the gauge with a known good AEM unit, with the same results. I put a meter on the 0-5v output of the guage and add alot of fuel across the map, and i get .2v at 10.3AFR and 2.xx at 14-15 AFR witch seems correct.

I call hondata, and they assure me there are not resistors that need to be removed in the ecu and it must be the AEM units fault.

Any help? Thanks.

Edit- attached are a log of a pull. NOTE that the AFR is 11.8 due to ME changing the voltage offset GREATLY for diagnostic purposes. Weather its 11.8 or 12.3 AFR, the ELD will only go as low as 1.4v

 

Not sure why Hondata is telling you no resistors need to be removed. I had the exact same issue and removing the resistors fixed it.

Give it a shot and see if it works.

 

i had to remove my resistors for it to read below 1.4v and give me a 10afr reading

 

thank god. Thanks guys. I kept reading rumors about it but when Hondata said i dont have to, I wasnt too sure.

 

all fixed, thanks guys
