Haltech newbie with pinging
Hey all, first the facts:
S5 13BT stock ports
720 cc secondaries
Haltech e6k
intake/3" turbo back
Ok, here's the story: I'm running my friend's map(cymfc3s), richened up for my 720s(vs. his 1600s), and whenever I roll on the boost, I get a rapid pinging. The sound is akin to a woodpecker, if you can imagine. It doesn't matter what rpm I'm at, it starts pinging. It doesn't matter how much fuel I add, it still pings. Sometimes rolling on the boost won't cause it to ping, but it almost always pings by the time it hits .15 Bar. I tried out the map that came with my haltech(a S4 13BT with a t04e and 720 secondaries), I got the same results. At this point, I'm suspecting either bad wiring, or bad injectors. But I'll be the first to admit I know very little about haltech trouble shooting. Had anyone ever heard of this? It's kind of weird I thought. I'd appreciate any suggestions on how to approach this, I'm probably going to need lots of detail on how to do stuff(like test injector impedence maybe?). Thanks in advance guys!
