I just had my first Quadzilla failure tonight. Basically rolling into the rest area notice that the display went all zero's and then started like a reconnect. Knowing the fuse tap is possible weak spot I double check it and thought I got it. Nope. Connect and the values where all over the map. Boost was bouncing 1 to 14 and back and forth. EGT's all over the place. Then fail to all zero's again. Then attempt to connect and lock up midway. Crap. Next stop I check the fuse tap again and the fuse itself. The same thing occurred again. Crap. Third stop... I decided to check the BATT connection and the ground connection. Wouldn't of figured my ground bolt had managed to come lose and you could here the relay in the Quad snap everytime I touched that ground wire sure enough the bolt was loose. Tighten the bolt and came home the last 20 miles. Now I'm going to watch my other BUGS I posted and see if this impacts there performance at all.

Today I pulled the entire loom out and checked all the connectors and added dielectric grease to some of the plugs that are getting hit with salt from the highway. Double checked my ground again and both power points the +12V BATT connection at the PDC stud and the +12V IGN in the fuse tap in the cab. After doing all this things changes for the better the gauges are much more stable and EGT are nearly matching with up to only +50*F offset between the ISSPro and the Quadzilla at its worst span. Double checked all connections and took it for a test drive into town seems smooth compared to last night with the up and down timing all over the map and boost reading bouncing 1 to 14 PSI.
