As far as I've found so far the ECU does not seem to be available by itself through online dealers. Is this correct or am I just not looking in the right places? My local dealer quoted around $1200++ for the ECU alone, add nearly 10% local tax &
. This would be for my '08 S4RS with the termi 'shorty' slip on.
All seems good & smooth over 4.5k, but she's giving me a little bit of a fight in the lower revs. Once in a great while I'll get a surprise 'surge' going around a slow corner in first. It's a little unnerving & I worry one of these times it's going to get me.
Would this DP ECU be the answer & solution to the bit of roughness I'm getting in the lower RPM range, or would it need to be combined with a PCIII (or other solution) to really shine? I'm not so much seeking for optimum power at this point, but more for improved smoothness & driveability -- that is
without going back to the stock cans!
I've read through the sticky on Closed Loop ECU mods & have gleaned some knowledge, but I'm unsure how sure-fire of a solution going this (rather expensive) route would be. There are so many here that hold vastly more technical knowledge than I (which is actually embarrassingly little). Who's got recommendations for me? Is there a simple solution I'm just missing?
