My 68 C10 chronicles, I'll see if I can keep all my info to one thread so I can find it later.
This LS swap started out with all stock 5.7/4L60e from a 98 Camaro. Only changes from stock would be the intake tubing/filter to fit into the truck and then the exhaust manifolds from a TBSS, thne through 2.25" exhaust to the rear of the truck. Put 17k miles on it that way. Only tuning besides all the normal deleting of emissions and VATS was supposed to be a small timing change.
I then changed out that motor for a LM4 5.3 block that was bored to 5.7 with Mahle forged pistons and Gen4 rods, ported 862 heads and a Z06(5308) cam. Same intake/exhaust combination. No further ECM tuning has been done. Yes it is running lean, very lean.
So, today I just got my HPtuners and LC2 wideband connected to my truck to start the new tuning process. I might be in over my head though.
I think that I have got it figured out how to log and save a file. Took a while to get the WB to display in the guages and chart vs time displays. Still havent got it to display in the graph correctly yet, but haven't tried really and don't know what to graph yet anyways.
Anybody care to take a quick look at a file, basically trying to make sure I can post a file properly for when I decide I "need" help. This is just a very short file for testing, but feel free to comment on anything that might help.

Ok, I'm having a couple of issues getting my HPtuner to cooperate. They are probably related to each other too.
First, Whenever I open the editor, I get a pop-up error.
The Second issue is that once a file has been read(and saved), it appears as if I can make changes, but i never get an option or ability to then upload the new file. The "write vehicle" option is grey'd out at all times.
Here is the error message..
"Unhandled exception has occurred in your application. If you click Continue. the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.
