ok, I have taken the test and have my Tuner unlocked, If you dont mind, which ones do I need to make sure are on to allow the system to see what I have. This is a stock 97 suburban.
These look... similar. But different enough to maybe make a difference. The EGR valves look identical but are different part numbers, I don't know what is different between them. The '07 EGR had fused power, the '02 gets power from the PCM, but I don't know if that is just a simple switched +12v supply or if it is a push-pull, reverse polarity thing. You could find out by measuring voltage on EGR pin 'E' - though I also wouldn't know if that would be hot whenever key is on, or only on at certain other times. The AIR system, the Suburban has a clutch? Or something? I don't know man, it's not my truck, telling you exactly what goes where and what settings will make these systems work together step-by-step is beyond me. I or anybody who could do that would have to have the truck in front of them to investigate things. Right now, that person is you, not me.
Well I made a few changes to more reflect the 2002 van file to start with. I believe that I now have the correct O2 setting and have disabled the air pump. Seems to run a little bit better with this tune. Does seem to crank a little harder. Anymore ideas of what I can change before I get the different injectors?
I just now seen your last post, and I completely understand. I am making a few more minor changes and then next time I have a Firday off I am going to take it to the machine shop near me. They say they have a tuner at the shop that would be more then happy to help me out.
Well I went to the yard and found some injectors from a l96 out of a 2002 chevrolet silverado 2500HD. I was also able to gather all of the electrical connectors. So no I believe that I only need the top hat adapters. The injectors that I have look ever so slightly different then the link you sent me. Seems like mine has more tabs on it. But I know for sure what these came out of, and they were the stock original injectors. Then I believe that I found a tuner near me with a dyno. So I think that's my next steps...
I am going to just purchase the ones that you provided the link for. And the I will get them changed out. I am also going to add a wide band. Once I get these injectors do I just use the injector data from a 2012 6L base tune?
No, because a 2012 has data in a completely different format than your Gen 3 uses. There is a link at the bottom of all my posts with a spreadsheet that has all the Gen 4 injectors converted into copy-paste Gen 3 format data.
