PiggyBack Chip on Previously Modded Car
Hey guys, so yesterday a new customer brings in a modded turbo that he picked up and says the car is stuttering (not plugs), surging and stalling under any type of load. He said the previous owner had it chipped so we started digging around in the back and found a really sweet rats nest
Basically what you see here is a piggy back system spliced into the factory harness with two boxes. The small ones is basically a boost controller of sorts. The entire unit forces the factory boost pressure sensor into reading only .6bar but upon measuring it manually ourselves it was running more like 1.2bar and on 91 etc... From what we could tell the car would run on a stock map until it sensed anything abover 4000rpms and full boost at which time the "piggback" would take over and force the car to do things that when tuned the way it was were not exactly safe.
PS Guys be careful who does the wiring because as you can see there are wires loose, shorted and generally left in quite a mess.
