Best LT1 tuning options?
For OBD-II there is LT1Edit and Jet DST, which is Tunercat for an OBD-II vehicle. LT1Edit is expensive and can tune up to 2 vehicles ONLY. Jet can tune an unlimited number, but at $100 per 2 vehicle license over the initial purchase (comes in 2 and 4 license versions). Each license is VIN locked.
For OBD-I, there is LT1Edit and Tunercat. LT1Edit has the same limitation, Tunercat is free to tune an unlimited number of vehicles.
LT1Edit is cumbersome, limited in its abilities, and extrememly poorly supported by carputing, the maker. Tunercat is much more flexible and is still supported by the maker. And yes, I own both.
Bear in mind, however, that neither is a tuning suite. They allow you to adjust parameters in the tune, download and upload to the PCM. For data collection and monitoring, you need additional items, such as Datamaster, Autotap, and a wideband. The wideband can be shared if you go with a portable, such as an Innovate LM-1.
The easiest way is to convert the OBD-II vehicle to OBD-I, then everything will be the same, but you will no longer be emissions-compliant. Just a thought.
