Crome Uberdata AFR Chart Graph Table Picture
Does anyone have that picture from Crome or Uber I dont remember where certain parts of the table are highlighted with the AFR they should be. It would really help me.
Just a little useful information for you to go by. The A/FR at an idle (500-1200 rpms) 27-17inches of vacuum will need to be richer then 15.0 with a large sized injector.
I didn't intentionally say "Hey I am going to steel this image to **** off nowtype".
I had no idea you created it, hence I didn't think it was a big deal to host it for the OP.
Honestly I didn't know you made the chart, I thought Blake did. Anyhow, sorry if I offended you.
Here is a chart that took 2 seconds to make.

interesting you made that in Uber (Im guessing) and not Crome.
Also, do you really run 12:1 all the way to 28psi? Hmm. After some insight from another tuner I came up with this graph (but I didnt know that thing about making it richer at idle)

Is that because you cant scale them down enough? Couldnt you like scale them down all the way and then adjust the main offset to take a little more out? What do I know, Im no tuner, just spent WAY to much time around them and I think I know what Im talking about

Your a/f ratio shouldn't be different at a higher boost level as your chart shows.
Fuel octane, engine load, air temperature etc are factors which are important :-)

These AFR charts are 99% useless anyway. Auto tune is a joke on any software I have tried to use it with. I always recommend tuning the car by hand in order to make sure the entire tune is correct. Auto tune cannot correct for tps tip in enrichment and or other variables like intake air temp and ect just to name a couple.

You are correct, however these charts are simply references for the newbie DIY tuner to know what to look for
