Procal with a manual trans?

Hey Guys.

Just out of curiosity, as in I wont be doing any work towards this for a while, but is it worth getting a Procal if you have a late 90's chevy small block TBI and a manual transmission? I understand the advantages of resetting the speedo and some other electronics, but I'm not sure my rig has the ECM for any of the fancy electronic connections that make a Procal really worthwhile. I'm just wondering because my dad and I have been having getting the motor running right and the question of whether the Prom chip is part of the problem has come up. Would a Procal help with tuning issues and such?

Thanks for any input or discussion.

You can not tune a TBI motor like that. I think you mean early 90's motor as TBI stoped in 95. Now if you have a late 90's motor (vortec) with TBI on it that is your issue getting it running. You need to have the computer tuned for the motor. If you need help tuning let me know I can hook you up with my tuner. Do you have any software to see what is going on with the motor?

Alright. I looked more at the Procal information and it says its only for '07 or later JK's so it makes sense that it doesn't work like that.

We don't have any software for that. And the chip is was new and bought from Howell efi. It was programmed for a stock 350 but I think dad had bought a slightly different motor. Unfortunately, it isn't a problem I get to deal with for now (I'm 300 miles away at college), so I will figure out those issues later. What kind of software are you thinking about, and what does it do exactly?
