2 friend and i have GT4 and the same ECU
first one is motor engineer, he did his maps himself as he knows what he do.
second take the first maps as base map and because he have different mod maps are definitively not the same.
And then I took final second maps as the second friend and i share a lot of mod, trust me : nothing works nice, i have to consider 2nd final map as base map too.
First time i tried it i could ear knock without detcan or det view meter.
Any local climat, any engine, any different thing made the map different, and as we want to drive more than 50miles around the house we have to make it safer than better.
