Helpful links for tuners:

[KLAB]

I've been researching a bit on tuning and trying to know what to do when it comes time to correct my pcm after a gear ratio change and emissions/cat delete. Here are some helpful links I found if anyone is in the same boat as I am:

LT1 PCM Tuning - Tips & Tricks for DIY Tuning.

LJ's PCM Tutorial, Version 2.1

Analysis of the effects on Spark Advance on LT1 engine at idle.

SCANNER READINGS - WHAT DO THEY MEAN?


Reading up on this has helped me out a great deal, however does anyone know of any good book(s) that I could get to read and learn more? The one thing that I am a tad bit INCONFIDENT about with my upcoming project is the computer...

Okay I finally got these two books in the mail:

• The Haynes Repair Manual is totally useless to me since I have the complete set of 1995 Camaro/Firebird GM service manuals. I have no idea why I bought it, but whatever its just something else to add to my collection.

• How to Tune/Modify Chevrolet Fuel Injection is AMAZING! I've been skimming over the pages and reading a bit and I recommend anyone who doesn't entirely understand how the PCM and sensors control the LT1 engine to GET THIS BOOK! I never knew what each sensor did and wasn't sure how it worked but just reading this book for a bit I completely understand it now. So it isn't just a "how to" book it is very helpful with a shit ton of explanations and pictures about how the PCM works.

anddd my book was "used" from amazon for 5 bucks and its really brand new. I don't think anyone ever opened this book it looks like right out a package. Anyways, I'm done bragging.

dont bother unless you have a load dyno and a wide band Kevin. all you should be getting yourself into for tuning is turning codes off for shit you have removed. i don NOT recommend and i will never recomend tuning a car yourself, its REAL easy to fuck shit up. and then you have no one to blame for a dead engine but yourself. leave it to a proffesional if the car need ANYYYYY air fuel adjustments or ESPECIALLY spark curve changes. LEAVE IT ALONE. ok ive sed my piece have fun blowing shit up cuz you wont listen.

For the sake of arguing... People have been burning chips and crap for thirdgens for over 15 years now. I know a few people who do it on their cars right now as well and have had very good success. One of them being a F1A Procharged 383... at that point I say just go carb but he wants the EFI and it's worked out for him.

You dont hafta be a rocket scientist to give yourself a base tune just need to be careful and dont go WOT all the time!

I'm just trying to learn how to delete the codes and calibrate the speedo and shit. Not gonna fuck with anything else lol.

ok good. as soon as i saw your post about spark curves on LT1's you got me a littlleeeeee concerned.


and Josh. how close do you honestly think there car is tuning it them selves and with a Chipped PCM?!?! Really. i bet they pick up 15+ rwhp gain driveablilty and there motor will last longer if it was tuned on a proper pcm and tuned professionally.

the EFI connections kit is CHEAPPPPP compared to a blown motor. or being stuck with cam surges and shitty slow reacting ecm's that no professional even wants to tune.
