I'm a believer in OBD-II scanners but haven't dealt with an OBD-I system before. I can read the diagnostics light codes.

Is there additional capability to be had with having a scan tool on my 89 IROC?

Blinking codes just shows you any stored malfunction errors.

A scan tool not only shows that but also shows what values the sensors are providing to the ECM.

Snap on mt2500 are nice but you can get older otc 2000 & 4000 models on eBay for a good deal.

Thank you. I followed up, checked out a few and the kit you linked me to turned out to be a good deal so I bought that one. The 2000 looked to limited with the smaller display.

Hi Tp
Have you had a chance to use the scanner yet?
I am looking at getting one just for reading the codes to see if the sensors are working correctly. I have no need to tune for better performance.
Just want to have a good driving stock car.

There is a special adapter for older gm tpi cars .

Thanks Tuned P.
About using tunerpro. I not sure if I can figure out the steps to make it work. I do by best on repairs but sometimes computer work (well I am a senior citizen) drives me a little nuts.
Do you have any preference in cables for our cars. 1990 GTA 305. I am willing but most likely will need guidance from the group.
So any help will be appreciated.
