misterp Posted August 21, 2005 Author Report Share Posted August 21, 2005 HEY NOW comments like that could earn you an opinionated hand gesture from the star, Lefty has a big ego, bad temper, and real problem with authority Yes, hairy arms, but it's better than some backs I've seen Thanks for the compliment, I just bought some gear lube at the store today, so if I can break 'the star' away from the keyboard long enough I'll finally make good tomorrow on that promise for how-tos on changing diff fluids.

ssfromsd Posted March 30, 2006 Report Share Posted March 30, 2006 How do i reprogram it? How much is it? Are there like different settings or what you can set it to? Link to comment Share on other sites More sharing options...
misterp Posted May 18, 2006 Author Report Share Posted May 18, 2006 How do i reprogram it? How much is it? Are there like different settings or what you can set it to? You need to purchase a software package to reprogram your own PCM; the three comercially available products are: * LS1 Edit (least expensive, not very user friendly, limited capabilities) * HPTuners (very user friendly, well supported, decent functionality) * EFILive (most expensive, very high quality product, supports extreme PCM modification, very loyal user following) Make sure that whatever software solution you purchase also comes with a really good data logging utility as well, or else you are just tuning in the blind.

Dave's SS Posted May 23, 2006 Report Share Posted May 23, 2006 I don't understand why remove the PCM? Just buy the Super Chip programmer. You can put in your settings, octane rating, top speed, rpm limiter, etc. And you can change it back to stock for warranty purposes. Just make sure to remove the fuse that transmits to GM while changing the settings, then put it back in. Super Chips will most likely need the VIN to program the OBDll programmer which is also a OBDll generic code reader. I paid $330 for mine, how much does a PCM cost that you install?

04ChargedSS Posted August 14, 2006 Report Share Posted August 14, 2006 SO THATS where that damn thing is! So then what the heck is that little black box attached to the driverside firewall, right of the master cylinder, that has all the wires that go to the computer?

wsaraceni Posted August 28, 2006 Report Share Posted August 28, 2006 is 30rwhp likely an obtainable goal from simply a tune? Link to comment Share on other sites More sharing options...

Tune all by itself, *probably* not but I might be mistaken. PCM tune combined with external engine bolt-ons (low restriction air cleaner (CAI) & catback) yes. This does not mean a tune by itself is a waste of money, at a minimum I recommend every truck have a aftermarket low-restriction catback and PCM tune, the truck will have both improved performance and economy, enough to justify the cost spent over the life of the vehicle IMO.

Mr. P. <{POST_SNAPBACK}> good to know. i will likely be getting a catback and intake as well. i was going to get a cam and a tune after i added stuff like long tubes and high flow cats but maybe ill just get a tune once before and once after all that stuff.

Cop Magnet Posted October 18, 2006 Report Share Posted October 18, 2006 Nice post! OK, I bought my truck used from a dealer, so no real info from any prior owner on what's in it (except for the obvious Gibson exhaust). Any way to tell if the PCM has been modded already? I'd hate to send it in to find it functioned the same. Link to comment Share on other sites More sharing options...
