I've had mine installed for a few yrs. and it's a driver, no sitting in the garage over here. I have a tip for you guys, go buy a roll of velcro tape(handy stuff for around the house), looks like a over sized scotch tape dispenser. When your sure that you have all the goo off the mother board connector, and you seated the power logger board by taking it on and off a few times, add a 2nd pc(mine came with one pc) of 1" square velcro strip to fit between the power logger board and the mother board(this 2nd pc I added above the USB port side of the board). This will help hold the power logger board in place, by having two pieces of velcro tape there instead of one. (I think this should be a standard practice if using the PL)
Also cut a very small little notch out of the kick panel like someone already mentioned, right where the USB cable, form your laptop, connects to go to PL. This was tugging the PL board down off the ECM MB on my car.
By the way if you have the PL, wide band and scan master, your ready to go "Speed Density" if you choose to. Nothing like being able to tweak (20) parameters in your ecm chip, while sitting in your driveway with nothing but the scan master and your gas pedal.... but that's a different subject.
I run a Turbo Tweak Speed Density Chip and every time that power logger board unseats from the mother board, the parameters in the chip get screwy. This has happened 3 times so far, but now I added that 2nd pc of velcro, that should put a end to it. Last week it happened, (for the last time I hope) when I pulled out from the light and some a hole wanted to butt there *ss in front of me, as two lanes merged into one, not happening, especially when there is no traffic and they assumed the antique car was slow.... maybe it's the stock 84 wheels?
