JDM ECU using B6 as analog input?

I have a JDM P30 with hondata v1, been using it well over 4-5 years (serial number 00164, ordered via a shop in Malaysia, Pentagon)

I've tried D14 the last time for analog input for LM1 wideband output, but it couldn't get good readings, so after swapping to a B20B, I'm deciding to try using B6 as input.

Hondata says remove R2, R3, and adding 0.1uf caps to C42, but I'm a bit hesitant to do it since the example doesn't say if it works on JDM ecus.

Anyone here has done it with any considerable success?

Bump hello? Just need confirmation it works before I start removing R2, R3 and C42.

It should be the same for a JDM ECU.

Thanks, going to do it then. Worried removing those bits might cause issues on JDM ECU.

Owh. if they used regular resistors I could've DIY, but the JDM uses SMD resistors. Looks like I'm going to have to find someone else with steady hands. lol.

Hope it works. Too bad hondata doesn't give upgrades for s300 to s300 v2. *hint hint*

Ouch 250 for an upgrade. Looks like I should try sell off my old one and ordering new for a better deal then.
