I'm about ready to start the fine tuning process on my TPI engine in my 88 IROC. I started looking for a plug in scanner to read codes quicker than using the old paperclip method and suddenly ran into a wide range of OBD1 testers. Sears has one for $65 and they then shoot up to over $300 and then take an even larger leap in cost.

Hey, I'm naive. What do I actually need to get? I've done a lot of little modifications here and there in search of every last ounce of torque & hp throughout the engine, drivetrain, and chassis. I want to be ready for future dyno tuning. Can someone educate me here please? Thanks, Nitro

 

Hi, check out Auto Xray...I have one and it works great

Here is the link and the scanner you need:

i picked up a auto xray scanner off of ebay for under $150 and it does OBD I and OBD II, so i can use it to identify codes in any vehicle just about (American OBD I at least and all 96+ Cars)
