Where is the best place to order a Scanner that has the LT-5 software with it?

Thanks!

I wish I could answer that question. Also, sorry for taking this long to answer you Don. Things have been a bit hectic at work. I think Bosch now holds the rights to the Tech series of GM scanners. I bought mine off of E-bay, used naturally, and I hunt the listings for software to fill out my library. New these things cost a fortune! Oh yes there are less expensive units, but then there is the software issue. Not all have paid 'use licensing fees' so you have to be careful on that aspect as it's the software that makes a scanner useful. Eventually I may just bite the bullet & flag down the snap on guy and buy/order the software I need..body control module & FX3 software would be nice!

You pulled the DTC's you listed in your first post, right? You used the paper clip method? I think I should review them and my diagnostic thought process so I may be more helpful to you. I'll do just that and report back later today!

Well very interesting find. Non of the sensors was causing my problem or a vacuum leak. I was able to borrow a ecm from a friend and put my prom in it. Now no SES light and all seems to be working right. The secondaries are coming on and it is running good. My ecm was rebuilt less than 6 months ago. May have gotten a bad rebuild. May be sending my ecm off to K&B Special Corvette Parts. I plan on taking the car down to Corey's in June and let him tune it and maybe check the injectors and weld up my corsa exhaust. I am getting short surges at cruising speeds.
