OBD I conversion questions
OBD I conversion questions I've been looking at some mail-order tuning options and I am begining to think that an OBDI conversion may be the best route (after I get all the inspection crap out of the way 
) PCMforless claims a 5 to 7 horsepower advantage over OBDII tunes, can anybody verify this? What are the downsides to doing the swap? Are there any?

You can either modify the OBD1 pcm by soldering a resistor in it, or you can put it in, and change to the 94-95 knock sensor in the right side of the block. The only negatives I have heard for the manuals is that you have a reduced amount of information to diagnose problems with the engine. Then you can buy a cable and pay the $75 for an email tune and upload that, or download datamaster and tunercat, see if you like them, and if you do, buy them and have fun tuning it yourself. I think it's fun, but then I am a computer geek as well. A cheap laptop would also be needed if you don't have a friend with one you can borrow.

Please forgive my stupidity, but what you're saying is that you can just change PCM's and then get the software and edit out the code? Seems simple enough I suppose...? And a helluva lot cheaper than LT1EDIT for OBD2...

They sold their OBDII files to JET, who now markets them as JET Dynamic Spectrum Tuner, for about $500. Which is also about the same cost as LT1 edit + cable.
