I use S300 in P72 USDM and wideband lambda PLX M-300 with digital indicator.

Situation :
H22A base map,
S300 Ecu editor in datalog mode,
value on M300 indicator =~14.7,
but in S300 Ecu editor AF = ~11.00 ! why ???

The version of S300 ECU Editor V1.1.1.0

Is your power and ground close to the ecu???

I use D22 for the ground even tho i was told it would mess stuff up but my M300 is perfect.

My M300 reads the same as my tuners Motec wbl.

Hope this helps

I solved my problems, thanks.

Can I use H22A stock map from Hondata in closed loop ? Or it's not smart usage ? My first target with S300 - fuel economy&good response map (for city cruising) for my ~stock H22A in Civic EK.

H22A stock map looks little strange for me... 450cc current injectors, +15% overall trim, why ? I use stock JDM 340cc injectors.

Yeah, just go to fuel trim in the parameters section and change the fuel injector size to 340 or so. It'll work fine. Thats what I'm doing right now until I buy my wideband.

Shadow! , have you try making the ground wire of the PLX as close to the ECU as possible ?

Yes, I connected PLX ground wire to ECU pin D22.

Use the voltage offset in the Wideband Lambda settings. Adjust it either positive or negative until the display and smanager read the same.
