I purchased the AEM wide band last month which is supposed to be the most popular one he has seen with his clients according to the engineer/owner of the Stinger PiMP. But I really pulled the trigger today when I bought the PiMP computer for my 5.0. It's based on Megasquirt technology but the thing that made it most attractive to me was the "plug and play" feature. It actually plugs into the EEC-IV harness connector of my engine harness. There is a vacuum hose that attaches to the engine and that's supposed to be it. So the "plug" part, at least, is accurate. If it "plays" nicely then I will be a happy camper. We will see if the base tune that is included will get the thing started. After that it's a session or two with the Tuning Studio software to see if it will auto tune and how well. I've never done this before so it is a new adventure. I will be uninstalling my Mass Air Flow sensor and replacing it with an aluminum tube to allow my cold air to still work. Right now I'm still running the plenum chamber manifold with 75 mm TB. I'm going to change out the Throttle Position Sensor (TPS) which was a donor item and install new hotter plugs. But besides that, I will do nothing to change the system. Since I will be going to the 8 stack EFI next, I thought it was wise to transition to the new computer with the same system that my EEC-IV ran on. If I get too many variables going, it could be problematic. I've heard the most important basic thing other than changing out the computer is getting the base time to exactly 10 degrees so it will match with the expected 10 degrees that is in the design parameters of the PiMP. It's a good thing my dash is hinged and can be released with not a lot of steps. I have to release the collapsible steering shaft and move the quick release hub behind the dash and then just work the dash down by massaging it a little. I will be installing a RS-232 line to the computer that stays in place. It's long enough to run out from under the dash and connect to the lap top on the passenger seat. The other big install is the wide band sensor and gauge. Not a big deal for the exhaust location since it will replace one of the narrow band sensors. However, I don't have any plans for installing it permanently; that is the gauge. Still haven't decided if that will be something I want to look at all the time. It will not really fit the design of the other gauges (digital and modern looking). I might install it with a cover over it under the dash. Well, that about covers the plan. One of my theories why the engine has been running intermittently off is that the PCM is crapping out. It is a 1992 donor item and it could have an adulterated file or two. We will see when I change it out. This operation will allow me to go forward with the 8 stack induction without too much fuss, I hope.

So wish me luck,
