Ok guy, so this is my problem. My car is a Ep3 civic usdm (sir) 2004.

In my search I have found that car run on wideband system. And, recently I have buy a lot of stuff from a UK Ep3 type-r. Apparently the UK system is on narrowband so when I have put the ecu... The car show me a cell code. I was think I need to change the primary Sensor for a narrow like the old 1999-2000 Honda. But what about the wiring after that?

 

Up.

 

Why are you trying to use a PRA ECU?

 

Hum, just because it was in the bundle of the euro type r stuff... Trying to save time and money of kproding... hate to put great looking stuff into the garbage and finally for working with the cluster, fuse box, keys, remote.
