ECU Flash Advice

I have managed to get an evo7 ecu working, sort of, with my evo 3 engine.
It runs it okay, but the problem I am having is with lambda.
I am simply not getting any readings whatsoever.

Its got a 2 wire lambda fitted in the standard o2 housing.

I have tried another o2 sensor, same result.

I do have a 4 wire lambda I could wire in?

The evo 7 ecu I obtained is running the Tephra mods, and I am uncertain exactly what has been done to the periphery settings and maps.

The ecu rom currently loaded is 96530006

Does anyone have a totally standard rom, I can use as a base to work from please?

I am wondering if some of the periphery settings are causing me some issues?

Many Thanks

Marty

You mean readings in EvoScan ? Best is to use a wideband to tune engine.

What did you end up doing in the end? I'm thinking about getting a 7 ecu as a quick cheap upgrade for now for my 4, di you use evo scan with it?
