[FONT="]Here is the DIY for how to do the wideband sorry widerange conversion for 01-03 honda civic[/FONT]
[FONT="]If you don’t know what this is just to give you an idea doing this conversions will allow you to run a PRB map in k-pro instead of PRA map. In English the car will be able to run off the sensor. This makes it a hell of a lot easier to tune via dataloging you can run lean protection, you can have the ecu just run off the sensor which tends to keep you afrs around a nice 14.7 all the time hehehe. It might not sound that awesome but once you are familiar with k-pro and you go without it and then go with it you will understand very quickly how awesome it is.[/FONT]
[FONT="]Things that you are going to need [/FONT]
[FONT="]1. [/FONT][FONT="] And most important and 04-05 honda primary widerange sensor. the ones off the RSX also work. And I have tried the bosch with no success the voltage doesn’t seem to be correct on all the sensors some work some don’t from what I have found with the bosch. here is a link to the Honda sensor that does work for sure [/FONT][FONT="]http://www.clubrsx.com/cr/DEN-234-9005.html[/FONT][FONT="] it’s $160[/FONT]
[FONT="]2. [/FONT][FONT="]An automotive SPST or SPDT 12v 30a standard relay[/FONT]
[FONT="]3. [/FONT][FONT="]Some wire[/FONT]
[FONT="]4. [/FONT][FONT="]Some ecu pins for both the wire and the ecu pins I grabbed and old wire harness out of a junk yard[/FONT]
[FONT="]5. [/FONT][FONT="]Soldering iron and some solder [/FONT]
[FONT="]6. [/FONT][FONT="]Some spades and a crimper[/FONT]
[FONT="]7. [/FONT][FONT="]The ability to pin and de-pin the ecu connector there is already write ups on this so I am not going to go into that one. And if you don’t know how use the search button then you are not deserving of this mod or I am sure someone will add it into this thread. Also de-pinning a connector is sometimes and art form some are easy some are hard and some people can do it better than others[/FONT]
[FONT="]First a couple of things I want to thank bryan(forcefedem2 or 02civicrider or ricerbryan lol) for sitting down and taking notes with me on this and I want to thank Edwin for coming up with this. Some of the pin numbers on skipbarber’s write up over on CF are miss typed which is one reason why I am typing this one up[/FONT]
[FONT="]So here is the diagram[/FONT]
[FONT="]And here is what the relay looks like[/FONT]
[FONT="]Now lets start with the o2 sensor there are going to be 2 black wires a white and a green(sometimes it’s a blue depends on the sensor and who made it) the 2 black wires are interchangeable meaning you can use either one.[/FONT]
[FONT="]Now on to the relay[/FONT]
[FONT="]You are going to run one of the black wires of the sensor doesn’t matter which one to Pin 87 on the relay but also on that same black wire you will “T” off a wire to Pin A22 on the A connector It’s the grey connector. Here is a pic of the “T-ed” off wire going into A22[/FONT]
[FONT="]Here is another pic of the A connector plugged into the ECU it’s the grey one[/FONT]
[FONT="]
[/FONT]
[FONT="]Now you are going to run a wire off terminal 85 on the relay to pin E8 the white connector going to the ECU here is a pic of the wire going into E8[/FONT]
[FONT="]And here is another pic of the E connector going into the ecu[/FONT]
[FONT="]Next you are going to run a wire of the 86 terminal on the relay to an ignition source I used the black and white wire off the C101 connector. The big gray connector by the ecu that connects the engine harness to the dash harness and I just “T-ed” into it.[/FONT]
[FONT="]Here is a pic of the black and white wire on the C101 connector[/FONT]
[FONT="]And another[/FONT]
[FONT="]Now on to the last terminal of the relay, terminal 30 you want to run a constant 12 volt to this terminal. I used the white with red stripe and 2 silver bands wire going to my radio for my constant[/FONT]
[FONT="]Now back to the o2 sensor now you should have 1 black wire left and the white and green(or blue) [/FONT]
[FONT="]That one black wire that you have left goes to pin A1 which is already an existing wire for the 01-03 primary o2 sensor it’s a black and white wire going to your old primary o2 sensor. you don’t need to re-pin or anything just make sure that you connect your black wire coming off your new sensor to the old black and white wire coming off your old primary o2 sensor connector.[/FONT]
[FONT="]Now same deal with the white wire connect the white wire of your new o2 sensor to the white wire on the old sensor connector.[/FONT]
[FONT="]Now onto the last wire the green(or blue) wire coming off the sensor this is the signal ground wire. You need to run a wire from pin A16 on the A connector going into the ecu the grey plug. And run that to that green wire on the new o2 sensor.[/FONT]
[FONT="]Now all the wiring is done you just need to open up your computer and load up an 04-05 calibration.[/FONT]
[FONT="]Hope that helps everyone I might come back in and add some more pics later and maybe some more detail this is not a project for the faint and only a handful of people have pulled it off properly.[/FONT]
