How is load measured/calculated?

mm3 vs. rev-gain maybe? :confused:

Injector Control Circuit Intermittent

Haha Good luck.

Just curious how load is measured?

Yes, but it also causes it to burn much faster. If timing is BTDC, and fuel pressure is excessive, the cylinder pressure will spike BTDC making a rattle.

Less boost should cause the fuel to burn slower and have less rattle. Too much pressure combined with too much timing would definitely cause rattle.

This is a good read, long, but good:...

For someone who doesn't have a lot of experience looking at logs, what is the biggest most obvious problem with this one?

All of them... :nixweiss:

Not on the tune you posted....

Yea, there was one frame that I saw 140. Look under fuel limiters, its the boost referenced limiter F0502.

Les, how did you figure out RPM? I was able to log speed, but not knowing the gearing....

How does this truck perform while driving fairly aggressively, compared to say a smarty tuned truck? Is there much to be desired, or satisfactory?

It hit 140 mm3. That is what you have it limited to in the boost referenced fuel limiter.

Timing I still haven't figured out.

I'm gonna be ready when it comes out! :grd:

Not really, I'll have to figure out logging and PIDs, and figuring out how to interpret all that.:throw:

No difference logged, or SOTP?

yea, I stared at it for a while, and nothing seems like it would be pulling timing.

Wow, awesome and valuable info Les. Thanks for sharing with us.

Seems to me like there might be a table we can't see yet....

click reply, then click on go advanced, then click the paperclip. You should be able to add it from there.

It might be easier to diagnose if you post the tune file.

Which ECM have this updated bootloader? Is there any way to tell without reading it with EFI Live?

Did you change all 5 timing tables or just the base table?

Questions in red.:notacrook:

That's probably all the timing your going to see on a stock tune, or have you already changed the timing tables?

Thanks a bunch, can't wait to hear the results.
