I've been chasing down a few problems over on the TBI board after installing a Holley 502-6 replacement TBI on my '88 K5 Blazer with a 350/700R4. I'm down to two aggrevating problems (thanks ShiftyCapone & Ronny!) due to the Holley larger injectors. I probably be calling tbichips to have a chip burnt that will bring things back to normal, but after spending many hours here researching this. It has become obvious that if I want to add more modifications, I need to learn how to burn my own chips.

So given all that, and the fact that this is the first ECM controled vehicle that I will be modifing, I need to learn chip burning from step one. Basically I need to learn everything that is involved and how everything interacts with everything else along with what happens when one parameter (say injector pulse width) is changed.

Can someone point my in the right direction? TIA

 

very first sticky at the top of this board.

 

Thanks, I looked at the stickys but it's not specific unless I'm missing something. All it sayes to do is to make your changes and save them. What I need to know is HOW do you make the changes and how do they interact with the rest of the parameters. Please keep in mind that I know nothing about programing a new chip or changes to the existing one.

 

It may be time to start looking at the rest of the stickies because the answers to most newbie questions are in there. That's why they are posted as sticky posts.
Interactions aren't that cut and dried. You have to look at the actual code to determine how a lot of these interact. The tables and constants are only just the start of it.
Once you get a tuning program, you will understand how to change the values.

 

i used tunercat for my tuning program. i found it easy to understand and they are very helpful in answering questions. this site is pretty much the place to locate answers either on your own or with help.
