idle with weird afr's, advice needed.
me and a friend got my 99nb idling and my afr gauge is giving me really lean readings.
we added alot of fuel to see if it helped but it was really lean. Not sure if its my gauge (i bought it brand new from someone here, gloshift gauge) I have my afr settings to custom linear wideband because my gauge was not listed in the drop down menu.
attached i have my msq and a data log i took of the idle after adding all the fuel.

I can't see what youre idling at... all I see is an option to display "O2", nothing for AFR. maybe because of your custom linear wideband
what are your low and high voltage values, and AFR at those values?
i dont know if you're using auto tune or editing the VE table manually at this point...but i always idle around 14.7, not 15.x like what you have in your AFR table. that's probably the DIYPNP startup map default for that table?

My gauge was showing afrs higher than 20. I added fuel to the ve table and I started seeing realistic afrs. My gauge was blinking 20 cuz that is its limit. I give it some gas to about 2k and the afrs go to 17 - 16 around there.

- what else do i need to do to be able to drive my car again? the pdf says drive after setting timing. ive done that along with the calibration of sensors. can i slowly drive and let autotune get my afrs where they need to be? my engine is vibrating alot more over stock.

what about the engine shaking at idle? what could be the cause of that? how can i fix it?
i cahnged the timing back to use table and i get timing advance 17.6 at idle just like the table. those default spark and afr tables are safe to drive on?

I can datalog something tomorrow.
my trigger wizard shows 17.6, i double checked my timing and made sure i hit the 10degree mark etc.
Ill log some idle and take it for a drive around the corner and see how it goes.
