Status of 2003, 2004, 2005, 2006 and 2007 truck engines:
LS1-edit is completed for 2003, 2004, 2005, 2006 and 2007 trucks for bench top programming. We are working to finish up the in-vehicle programming capabilities. At this time, you can program the PCM in the vehicle only if it is electrically isolated from the rest of the vehicle. This can be done with a small harness available from www.speartech.com. Once we have in-vehicle programming capability completed all 2003, 2004, 2005, 2006 and 2007 truck customers will receive the new software.
WHAT IS INCLUDED:
With your laptop, LS1-edit provides everything you need to tune your car. Our package includes the OBD-II cable for your vehicle, the Cable Interface Module, the USB cable to your laptop, and the software to read, program, and edit your PCM on your laptop. Mailing via air is even included (to U.S. locations, shipping outside the U.S. is extra).
We are currently shipping both the unlimited-PCM version and the PCM-locked version of LS1-edit. Both are in-stock. Upon receipt of fully paid orders, we ship within 2 business days.
We have also simplified the ordering process. Since we include everything, once you place your order, we ship the entire package. You do not need to get a separate cable and read the PCM ahead of time. One step, and you've got it.
Ready to order? Here is a link to the LS1 order form for PCM-locked purchases: LS1 Order Form
Interested in ordering the unlimited-PCM version of LS1-edit? Here is pricing: LS1 Unlimited Order Form. Customers interested in the unlimited-PCM products, please check out our Winter Special package!
If you already have the unlimited-PCM version of LS1-edit and want to add new years or models, here is the pricing: LS1 Unlimited Upgrade Form.
LS1-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 200 or AMD processor with at least 32MB RAM. You will also need one available USB port on the PC. This is used for the OBD-II to USB converter we provide.
One word of caution: if you want to add additional PCM's for LS1's at a later date, you will need to return the Cable Interface Module to us for updating.
Please note that there are no editing functionality differences between the unlimited and locked versions of LS1-edit. The difference in these products is that the locked version will limit the number of PCM's you are able to tune.
The PCM-locked version of LS1-edit can license between 1 and 4 PCM's. After 4 licenses, you will need to purchase an additional LS1-edit package.
A word of warning: Please only program your PCM using an LS1 file that was read from your specific PCM. Do not try to program your PCM with an LS1 file from a different PCM. To minimize programming time, we do not completely reprogram the PCM, only the data segments. If you use a different LS1 file, the data in the LS1 file may not match the code already stored in the PCM. If you attempt this, you may end up with a PCM that is non-operational.
If for some reason your laptop loses your LS1-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.
LS1-edit and LT1-edit are the number one tuning tools for GM V8 engines. Tune your car or truck with the same tuning tool that the pros use. LS1-edit and LT1-edit are used by professionals around the world to tune some of the fastest LS1 and LT1 based cars and trucks. We are always getting requests from people looking for local tuners using LS1-edit and can tune their car for them. We have received permission from the following professional tuners to post their name and web address information. Click HERE for some LS1-edit and LT1-edit professional tuners.
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.
