[QUOTE="ALBundy, post: 361949, member: 15"] Piggyback ECUs have a serious limitation. I used to have UNichip as well. First, piggyback ECU doesn't work well when the car is operating under close loop. Over time, the new mapping is over-ride by the stock ECU, and only works in open loop conditions, ie WOT. Secondly, the tuning done with Unichip is worse than generic to say the least. If you get a DME reader and extract the maps out and view it in 2D, and then observe how the Unichip is being tuned, you will know a lot of interpolation work is being done, otherwise there is no way to churn out a completely new map in one day (most of the time half day). I have seen Jim Conforti's mapping (extracted out and compared to stock), almost all the points in the matrix are tuned individually (compared to stock) and that takes a lot of time. So the best best is still to get an upgraded map flash unto your ECU (superchip, hiop, upsolute and etc), then further fine tune it on the dyno. Bernard of BVO in Singapore would be the best person to fine tune the vehicle. Cheers [/QUOTE]
