Twiztids4

Hey guys I'm trying to help out my stepdad and his son. They tried putting a turbo in his sons 350z and ended up blowing it up. Now my buddy and I put a crate engine in it but the ECU still has a turbo tune on it. I bought another ECU for a 2004 but I guess they we got a late 2004 ecu with air/fuel meters instead of 02 sensors. Can anyone re flash the original ECU that's already turbo tuned back to a stock map?

Thanks in advance
Also we have the newer 2004 ECU that we paid 225 for it anyone needs one.

Welcome- that's an interesting first post. You may have another problem with running that '04 Z, as I'm not aware of any changes to the ECMs in either early or late production '04s. They all utilized sensor info on air/fuel ratios via 02 sensors for the VQ35DE. As for reflashing back to a stock tune, any Nissan dealer with a CONSULT III system can do that. It's not something any of us can do across an internet board...
