Did you keep the primary O2 sensor for closed loop?

Thanks for the info.

Yes, exactly. Primary O2 sensor is left totally as it is, and the aftermarket wideband just replaces the stock secondary sensor and is connected as described above. Closed loop works just normally.

You should not connect this, as you will probably damage the ecu.
I have an Euro Civic Type-R and have been using AEM UEGO's 0-5V wideband output connected to ECU's SO2 input for about year and a half now without any problems whatsover. SO2 has an input range suitable for 0-5V.

You cannot input ...

You need to keep the OBD disabled anyhow, since otherwise ECU will throw a CELL because of the missing secondary lambda (which is replaced by the aftermarket wb lambda).

Alright.. so I need a wideband lambda to tune it properly and run safely?
Yes.

I drove to work this morning with the OBDII enabled. It is a 17 minute drive. The MIL did not light up. Shouldn't it do that when there is no cat?
Yes it should, and it will. It just takes a little bit more than that ...

Euro EP3s don't have the wideband primary O2-sensor. To be able to read/datalog wb O2-values, you'll need some sort of aftermarket system, for example AEM UEGO which has it's analog 0-5V output wired into ECU's SO2-input.

Gear readout works fine for me too. I am using KManager 1.2.0.9 / Sept 2005

I've had this exact same issue occasionally a couple of times with '04 K20A2 Euro Type-R when the weather was really cold. Probably bad connection between ECU and KPRO? Hasn't happened now for months though.

It's easy to know if you need to enable traction control:
If TPS > 100 and speed(t-1) <= speed(t) and rpm(t-1)>(factor x rpm(t) )then
reduce throttle or Ignition or boost?
How can that work? Speed sensor reading (VSS) and rpm are always linearly related, i.e. speed(t) = factor x rpm(t), factor > 0 ...

I finally tried out this version tonight. My car absolutely hates this verion as it stands right now. First it started up fine and seemed totally normal. Took it for a spin and right when I hit a turn GAS pedal does not work. RPM dropped down really quickly and just shut off. Tried to start up the ...

since now european ctrs can datalog with a so2 wideband sensor and see the voltage of the sensor in k-manager, why you don?t make it possible to see the values in a display as the us guys have, with a converter of so2 voltage to a/f ratio .
this will help so much in europe, do it pleaseeeeeeeee ...

Parameters -> Misc -> ECU Options

OBDII enabled (Sec O2, FTP, PA, ELD)

I did the suggested 3 runs per cam angle, so 3*6 runs in total for the lowcam. There is still quite a lot of "noise" in the runs like you said, but a friend of mine is currently looking at into more sophisticated ways to do the smoothing.

Update: Documentation now done, system is ready for some testing / use by anyone that wants to give it a whirl.

Yes, like I said above you can see the A/F values (shown as voltage level) by looking at the sensor SO2 in KManager.

You need a wideband lambda. A good and working setup is to replace your secondary lambda with AEM UEGO, and route the analog 0-5V output from AEM to ECU's SO2 input. By doing this, A/F ratios can be monitored while driving with the gauge, and also datalogging the A/F works great! Downside is that in ...
