I am wanting to swap over to the tpi system. So I called www.FuelInjection.com. They have the whole setup for my car. But they said that are having trouble with burning thier chips. So he told me to go with a after market computer setup. Well we are talking about some money thier. So I would like to learn how to do this myself. If someone could help I would surly repay them.

Scotty,

You are in the right place. Learning to do the tuning yourself is a must unless everything is stock. If your vehicle came with a TPI just find factory parts, save a bunch of green. If your vehicle has been modified in any way, which is why most of the people here got started, then you will have to make changes accordingly.

Start at the beginning, TPI, TBI, DIY PROM message boards and read. There is a steep learning curve so don't expect it to all fit together right away.

I suspect that the problem with "burning their chips" comes more from the difficult and time consuming process of tuning and they just don't want to spend the time it takes to do it. Time is money.

Good Luck

 

syncom, the more close to stock your new TPI setup will be say to any of the L98 TPI's, or 305 TPI's you'll be able to fight some of that "steep learning" curve because you could borrow some of the OEM code / tune hopefully. Start with the stickies up above, GREAT info there. I took the plunge last year after reading over and over about tuning for almost 3 years. I'd never go back. The scary thing is if you try it blindly (some people may in a rush) you can destroy your project quickly. IF, you take an organized approach, baby steps and don't change a ton of things each time you'll be alright. I made the mistake in the beginning of trying to change a bunch of things and quickly lost my place only to have to start over. Take a look at moates.net for all the hardware you should need. What are you trying to put a TPI in?? 3rd gen, truck, something else?

 

Be sure to read the stickies over and over again
you can learn alot
