Hi all,
I've decided to dive into tuning and don't understand anything I'm looking at on this forum, so I figured it's the perfect place to start!
I'm currently working on an 85 fiero gt. I replaced the original ecm with the gm 7730 service no. because of its' speed and ease of adapting to the Fieros harness.
All is well, but I'm a perfectionist and the mail order tune was great, but I want to learn and make it fit my rig better.
I'm looking forward to lurking and eventually posting and learning!
