Hondata

Tobi and the guys at TC Perf are awesome! They tuned my S300 and I'd recommend them 100%.

Here is an excerpt from the PLX installation guide.

Don't cut the wire, just disconnect the stock sensor from the harness. Make sure you install the capacitor that PLX includes w/ their WB.

I used the stock location for the WB bung and then used the narrowband output from the PLX into the stock O2 sensor pin on the ECU. Then I used the white/linear wire and connected that to the EGRL input. With my setup the only purpose of the wideband signal is for datalogging and tuning.

oh ok I think I got now, correct me if I'm wrong

1st connect the wideband wire to the ELD input on the ecu
2nd use the plug off of my dead o2 sensor then put a 1k risister on the 2 black wires and connect the narrow band wire to the white wire lleave the green wire alone on the plug, then connect ...

No, we do not do ecu repairs. I would suggest taking the car to a Hondata dealer so they can use the process of elimination to determine where the problem is. Where is the PLX getting it's VSS signal from and how do you have it connected?

Thanks. I had the car tuned by a local Hondata dealer (TC ...

It must be a problem w/ my ECU. Does hondata do ECU repairs? I would hate to have to buy another boost kit and have another ECU socketed.

if everything is good untill it gets to the ECU then it's probably the ECU.

possibly bad solder job, etc.

Hondata will probably ask who the dealer was.

That is what I figured too, but thought I would ask. The dealer was importparts.com but I have a dealer local to me if I need to have it ...

Here are the hondata instructions

Here are the PLX instructions for wiring it up to replace your normal narrowband O2 sensor.

Basically you just wire up the grey wire from the PLX to the NB input to your ...

Hondata S300 installed in a USDM P06 ECU by a Hondata dealer w/ Boost option

Problem: I am getting a VSS code and the vehicle speed doesn't show up in SManager. I have a PLX R300 hooked up and it can see the signal from ...

Thanks. Do you know of the P06 contains all the hardware required for EGR if I want to use that input instead?

I have a S300 installed in a P06 ECU. If I decide to use the ELD input for my PLX wideband do I have to anything physically to the ELD to disable it or is all that is needed is to disable it in SManager.

Secondly, I am considering using the EGRL input for the WB instead of the ELD since my CRX w ...

Nevermind, I found the pictures in the SManager help file. I knew I had seen it somewhere.

I just got my S300 from the dealer and it looks like they forgot to send the boost solenoid in the package. Now I am wondering if they forgot to install the boost control hardware as well.

Does anyone have a picture of the boost control components so that I can check to see if they have actually ...

Do you know where to get one of those? I didn't see it in the list of calibrations which came w/ the S300 software.
