Re: xr6 hp au ecu into non xr6 ?
The dollars just to get a better idle and a slightly more agrresive A/F mixtures probably aren't worth it unless you get one cheap but you also get an ecu that if its auto gives you adaptive shift and auto or manual will correct your speedo output for 3.45 diff gears and low profile 225/50R16 tyres with the correct light green speedo drive gear. So it has some other advantages.
