1994 and 1995 LT1 Tuning
Once you've got the cable hardware, you will need some free software to check things out. Here are two freeware tools that will help you along
Now that you've read out the contents of your PCM, you are ready to purchase the tools you need to start tuning up your car's performance. The software includes the LT-1 editor, and the PCM programmer. Here is user's guide for LT1-edit LT1_Edit Users guide.
(Here is some older information from another website about the editor and programmer: LT1_Edit - THE Editor for your F, B, or Y body Car!.
E-mail us your .lt1 file, and go buy the editor, and start tuning!! We will review your .lt1 file for:
Here are the main features in the expert editor editor_features
Any questions about the editor?? Just ask PCMdoc@surfree.com
Now you've got your tuned up program. Time to reprogram the PCM in your car. Fire up the PCM programmer software (you did order it, didn't you?), plug your PC into your vehicle's Diagnostic Connector, and watch it go. Once it's done, you'll need to power down the PCM (turn off the ignition), and you're off and running. Take you car out and see what it will do!
Now you will need the logging scanner to record your improvements, or to understand where you need to do more tuning. This software will let you record all the major engine parameters under all engine conditions. So, take a run, look at the results, and tune it until you like your results. The latest version of the scanner will let you log your engine parameters up to 10 times per second.
LT1-edit runs on Windows 98, Windows ME, Windows NT, Windows XP, Windows 2000, Windows Vista and Windows 7 operating systems. Minimum hardware requirements are a Pentium 133 or AMD processor with at least 32MB RAM. You will also need one available USB or serial port on the PC. This is used for the ALDL converter.
If for some reason your laptop loses your LT1-edit software, during your software update period we can re-ship it to you at no cost. After your software update period expires, there will be a handling charge for software re-ships.
Do you have a 96 LT1 and want to use a 94/95 PCM to run it? Yes you can! It works fine. Here is a link to what you have to do: OBDII to OBDI Conversion.htm. This page came from the camaroz28.com Bulletin Board.
We have found at least one aftermarket laptop automobile DC power supply that could destroy any cabling between the laptop and the vehicle. This power supply connects the laptop ground to the vehicle's battery +12. Any cable connected from this laptop to the under-dash connector could have +12 volts put across its ground connectors. There are two conditions you must be cautious about. 1) If you are powering the laptop from a DC power supply plugged into the vehicle, then the laptop ground could be held at a voltage above or below vehicle ground. 2) If you are powering the laptop from a wall outlet and also have the vehicle on a battery charger, then the laptop ground could be held at a voltage above or below vehicle ground. If you are unsure about your laptop power supply, you MUST measure whether there is any voltage on the laptop ground measured against the vehicle ground.
