Flash PCM Programming Software

This is what got us making cables in the first place! If you're an LT1 owner, and own only one piece of software, THIS SHOULD BE IT!

Back in July of 1999, I started corresponding with a couple of guys who were working on hacking the PCM found in the 1994/1995 F-body and B-body cars. They had just gotten the communications routines working, and had a editor that was "roughed in" but needed some testing. So, I bought a spare PCM from my local junkyard and volunteered to be a "guinea pig" for the software. I helped provide feedback on operational characteristics of the software, and they kept sending me updates. :) Dave and Ken have been great to work with, and I look forward to working with them for a long time in to the future! It's a great product, and I guarantee it's worth much more than its cost!

The software is called LT1_Edit, and right now it ONLY works on the 1994/1995 LT1 PCMs (that includes Z28's, Formulas, Trans Am's, Caprices, ImpalaSS's, Roadmasters, and Corvettes). It does not work on any other platform. Right now there is no plan to migrate it to other platforms either. There is an OBDII LT1/LT4 version in the works, and it anticipated that it will be released in January 2001. I have beta versions of the OBDII cable and the editing software, and they're working very well! :) 
LS1's, here we come...

You can check out LT1_Edit from Carputing at the Carputing web site

You can also read about the functionality of LT1_Edit at the LT1.net Editor Pages

There is also a mailing list for LT1_Edit that I highly recommend - I am on it (have been since day 1 - "Hello World"), and we discuss all sorts of tuning specific topics, with a little fun thrown in occasionally. Even if you don't have a LT1 car, you might subscribe to listen in on the concepts being batted around - you never know, you may learn something - I know I have! Even though we're tuning LT1 cars, conceptually, the techniques used can be applied to many different vehicles, both MAF and MAP based. Here is a link to the mailing list

I don't sell LT1_Edit, but I use it and highly, highly recommend it.

What have I done with it? You can read here about The Black Car (that's its name)
