Throttle Performance Switch on 82
Since this only works on 82's and up has anyone with an 82 tried it? It installs in less than a minute (plug and Play)
I'm curious as to the difference, if any, in performance.

Looks like something that's supposed to fool the computer into thinking it's open wider than it actually is. That would probably cause the computer to advance timing and squirt more fuel. Or whatever.
Hmph...do these guys REALLY know something GM doesn't about fuel injection?

I'm interested also, what does it do?
I added a plug in mod to the trans that only lets the converter lock up when in drive. I keep it in 3rd for normal driving and its great not having it lock up at 30 mph, what a pain in the a$$ that was. I use drive on the highway and it locks up in OD as normal.

What the switch does is the following, it modifies the TPS signal so that the ECM gets a WOT signal when really you re not at WOT but 75% throttle... and what does this do? Nothing, when you mash the throttle the nanosecond that WOT kicks in earler because it starts at 75% rather than 85-100% (depending on TPS adjustment) is nothing, think about it..when you floor it you floor it in one go. The switch is 0,10$ worth of parts sold for 100$, it's right up there with those performance mod things sold, which in all reality is just a 640Ohm resistor plugged into the CTS harness to trick the ECM into thinking it's in open loop w/ cold coolant adding a few more degrees of advance & fuel... waste of money. That 100$ is much better spent towards a decent cam, the stock stick in yours is like a straight shaft with boogers on it...that's how pathetic the lobes are.

Well said!
You guys confirmed my suspicions. I can't believe they charge $100 for that thing. I could go to Radio Shack and make one for $5, but it still isn't worth it.

While we are here...how about the HyperTech Chips?
I had one in my other '82, the Stage II chip, and "think" I felt some gains, however the gains were more in the transmission not shifting into OD until at highway speeds...thoughts?

No prob, drop me a note anytime, you can check out http://www.crossfire.homeip.net also for more crossfire enthusiasts
The hypertcrap chip well ehh, what shall I say. The lockup disable in lower gears is nice and that's about it really. The lower temp thermostat is a bad idea in a cold climate, you may run the risk of never getting the coolant temp high enough to get into closed loop.

I don't know why they recommend it, they altered the fuel tables also but i think it's a marketing gimmick, the one about a cooler engine making more power. BS IMO, the temperature difference in the air entering the engine is minimal and therefore the performance increase nihil, also the cooler running engine will loose more combustion heat to the coolant because the temperature difference is much higher and this difference is the driving force begind energy (heat) transfer. I would run a 180F thermostat. I had the hypertech chip also and ran that thermostat.

p.s. what cam would you run, and will a new cam effect the chip and the ecm??

depends on the rest but a compucam 2030 or 2040 is a nice start without inviting problems with too much overlap, pumping loss due to long duration & such...(drivability issues)
With a 2030 and 2040 it should run pretty nicely w/ the stock ECM, an 82 ECM w/ automatic prom (for an 84!! the 82 and 84 ecm may be interchangeable but the prom is different) will have better idle control, it's plug & play. A 1227747 ECM (there's another one, forgot the # but it's an F-body TBI ECM w/ IAT sensor & lean cruise) can be installed with a prominator ( http://www.speedtronics.net ) and you can tune it. May sound complicated but it really isn't all that complicated. With the edge card connector offered at speedtronics you will be able to plug in the ecm without cutting up the harness (converts from pin to edge card)
