Hondata

hi All,

I am noticing something odd on my afr overlay. I am attaching a screenshot showing sudden drop of my afr in certain cells.. I am not sure if this is caused by a defective ecu.... here is the table. please note that the afr suddenly drop to lean. Is is a ecu issue or s300 issue.

Thanks

By the way I am using a s300v3 and uses LM2 for the O2, wideband fed to the S300 analog 2 input. O2 is located at the original O2 bung. All sensors shown on the PC apps are working and accurate. specially the AFR.

I have a question. When you set the S300 to autotune., where does S300 stores the table it uses? I am impressed with hondata's autotune's ability to provide an almost perfect
fuel tables (both low and high). My questions are, when does auto tune ends? when it ends where does it store the fuel tables ...
