Also, Where did you put your front o2 sensor? Make sure that is good too.

Did you put the stock front sensor back in? That may be your problem. I'm not talking about the wideband sensor. I can help change the evo stuff over when I get off work.

Here's the tephra downloads. Go to post #2 and download option #1. https://www.evolutionm.net/forums/ec...hramod-v7.html

Then go to Roadspikes big maps and download the NON SD rom to get the maf and injector settings. Basically copy everything from Roadspikes rom into the evo rom. Take your time. My work computer doesn't have ecuflash so I can't help copy it over for a few more hours until I get home.

No I didn't since I have custom DP I don't have the Bong for the other o2. Should I weld one for it and throw it back in.


Also, just tried to get my sstock rom and said my definition file couldn't be found. I used Senate6268 zip file of definitions and saved it under my rommetadata folder. Changed ECUFLASH ROM location to that folder. and nothing.

Be sure to get the evo VIII rom. The evo IX memory is too big for the 02-03 lancers and won't fit into the ecu.

You definitely need that front o2 sensor to run in closed loop. Closed loop is idle and cruising. Put the o2 sensor in. I say move the wideband sensor back a bit and put the cars front o2 sensor in the current bung. I bet if you put the car o2 sensor in your idle will be fixed. But definitely have a second bung welded in.

Try this test. Pull your car battery cables (to reset the ecu) for 10-15 minutes, put the cars front o2 sensor in the bung, then hook up the battery and see how the car idles. If it works you know its the o2 sensor. I wouldn't recommend cruising without a wideband though.

I can put the O2 off the turbo DP? and I will try this im going to weld another bong!

Yeah take the wideband out and try the cars o2 sensor. I'm positive thats your problem. You NEED it in to idle and cruise. Otherwise the ecu doesn't know if it should add or take away fuel to get to stoich (14.7 AFR).
