I finally got my car running. Seems to have a rough idle although I'm pretty sure the basemap just needs some tweaking, or considering I'm throwing code 20 my voltage is low. My wideband won't read, I've calibrated several times, could this be related?

I got my alternator tested and it came back good. I've also checked all my grounds. All my connects seem to be suffice. I did also notice my battery is 7 years old now and seems to work but it has tipped over and leaked before. I'm thinking of upgrading the battery today with a sealed one.

Any ideas on how to continue trouble shooting this? I've read do articles and can't seem to find any more answers. I'm stuck and I am so close to getting dyno tuned.... Please help me!

 

7 is like 50 in dog years and 100 in battery years lol.

Wide band will have nothing to do with how the engine runs. Find out why your voltage is low and throwing that code. Might just be the battery. Get your wide band working and make sure your afr is good at idle should read 13.5-14.5 at idle. i just sold my AEM fail safe AFR after it glitches and starting reading wrong sent it in and got it repaired but sold it and bought the new innovate mx-L AFR its the most accurate reading AFR out and has less wiring very easy to install, Then go get tuned.

I thought my wideband problem was related cause my dome light was dimming during idle which makes me think my voltage is really low. I've read that innovates won't work or mess up when underpowered. Going to test my battery tomorrow, might just buy a new one regardless.

 

Who said that lol!

Innovates AFR is new and updated compared to all the other AFR gauges on the market.

Your wide band is not working either cause its defected or like you claim your voltage is low. It will have no affect on how the motor itself runs its just a sensor. Get the voltage fixed and your AFR will most likely work, But what i want to know is whats wrong with the AFR? whats going on with it? is it just reading wrong? if so have you confirmed this anyway like on the dyno or laptop? or is it not turning on?

 

Sorry, maybe I'm explaining poorly. I'm not saying my AFR is has anything to do with my code 20 I'm saying that I think I have low voltage and its not letting my AFR read correctly so I have no idea how rich or lean I am. I calibrated it like 3 times and it just sticks to 22.4

 

how are you calibrating it? maybe its the power source your using to power the afr gauge! do you have other electrical issues like lights dimming or radio dimming ect..

 

I'm calibrating per manufacture's instructions. It even says "cal" on it as it supposed to when it calibrates. I'd have to double check how it's wired, it worked perfect the last two years though. My dome light was dimming. I noticed my oil pressure sending unit connection is ripped apart. Not sure if that'd mess with anything but I'm going to solder it regardless. I think I'm going to have to thoroughly inspect all my wiring

 

Can the ELD be replaced in the fuse box? Where the hell do I get one?

 

I found some fuse boxes on eBay under $20. Thinking I'll replace mine and see what happens.
