Scan tool question
Is there a scan tool out there that is reasonably priced that can read stored codes, step the IAC, set the TPS, check O2 sensors, and provide real time data when driving ? Oh yea, just because a scan says it does ODBII, does that mean it does ODBI also. My car is a '91
Thanks

Is it easy to differentiate between the two?
I would like to have one just to check for knock events etc. Time to check ebay. Would a GM dealer sell one of these or would they give me the typical run-around?

How does this look? Tad expensive, or on the money?

TTS data master is cheaper than ease (which I have and like) and I believe it does about everything
diacom is around too but is DOS based and kinda clunky.
EASE does have some annoying bugs in it and I haven't been too please with support for the LT5.
the nice thing about ease is you can do all the OBD I style GM cars and it has cables for both the OBD I and OBD II style connectors. even though all the LT5s are obd I computers, they switched the #%$* connector on later cars which is confusing.
EASE does a pretty good job, but I think if I had to do it again I might buy the cheaper datamaster.
tyler turned me onto this software after I had already bought ease.
maybe he will chime in on this soon.

Hey, what can you do with a Tech-I? Is it easy to get the right cartridges/programs for it? That might be pretty cool since it's only about twice the cost of a decent OBD-I software package like EASE, etc.
Are the tools pretty reliable? Can they be fixed or serviced if the Tech-I craps out?

Any car that is OBDI uses a PROM, not an EEPROM. The first stands for programmable read only memory, the second stands for electronically eraseable read only memory. This means that the PROM can only be erased with the use of ultraviolet light, and then reprogrammed. This cannot be done on the fly with a computer. The PROM must be removed from the ecm to do so, then reprogrammed by a computer, and then replaced into the ecm. The OBDII cars use EEPROMs which are never removed from the ecm, you simply change parameters, reflash the memory (no longer called a chip since there isn't a 'chip' to removed from the ecm) and changes are made!
Long story short: Tech 1 can only monitor and record data from the ecm. To change the calibration, you must remove the prom and reprogram it.
