Yesterday I had RR session and a 156 GTA saloon remap done by guys in VIEZU.
The 3 runs before the remap showed 182kw from the engine, which is 2kw shy of promised 184kw. I am happy
Car has done 73000km which is around 50000 miles? 2002 year car!
Best run before the remap showed 253,5 nm at the wheels (294nm at flywheel-300nm was advertised) and 155,3kw at the wheels (then its around 182kw at flywheel).
VIEZU promised around 24hp increase in power and 29nm in torque.
156 3.2 V6 GTA 24V - Car Tuning, Performance Engine Tuning, ECU Remapping & ECU Remaps
Ofcourse I was not that optimistic at all.
Modifications that are done to my car-
only GTV 2.5 catless manifolds. Everything else stock.
Figures after the remap went better and better after each run. But there are 3 tries so I give you the figures that I got after final third try. Maybe if I had continued, the numbers would have increased even more-dunno. Will try again after few months, when the ECU has had time to settle in with new map.
262,7 nm (from wheel) which is 305nm at flywheel
161,4 kw (from wheel) which is 190kw at flywheel (~255hp).
Which seem kind of low :/
But then again maybe the ECU needs just time? Like I said the performance went better after each RR try.
Can anyone tell, what is that weird drop at 5500 rpm
