Are you trying to inspire me or annoy me with that comment?

Also, I cannot find the tun file you sent me with all the things you have been trying, can you please send it to me again? ross at efilive dot com.

Thanks,
Ross

Inspire, inspire, and only inspire I'll send the tune file. I only sent the logs showing when the problem was happening.

Thanks Ross,
Rob

Shows how bad my memory is, I thought you had sent me a .tun file!
Anyway, see how it goes with the one I sent back, I'm sure others following this thread will be interested.

Cheers,
Ross

Yes they will!

After looking at the changes Ross made, I had my doubts anything would be different. Well, I'm wrong again

Not sure why it worked, but the truck now revs at least up to 4000rpm's. The truck still pulls power over 3500, but not nearly as bad as hitting that 3500 wall.

I'll continue to try modding the tune to see if I can overcome the defuel, but thanks to Ross we're headed in the right direction.

Thanks Ross, I guess I need to take my foot out of my mouth now. You guys have a great product and support.

Okay, so what changes were made? I need to get this figured out before next weekend.

Nothing super secret, it's all in there already.
Just make sure tables B1115 & B1116 have 'normal' values from 3500+ as well. Easiest way to do that is copy the column at 3000RPM and paste it in to every column up to 4000RPM.
Next, fill B1117 with 200mm3 all the way.
Then fill B1118 & B1119 with big numbers all the way to the end too.
Lastly, do the same as B1115/B1116 to B1122 (copy the column from say 2400RPM into all columns up to 3500).

That should do the trick.

Cheers,
Ross

Thanks Ross. I just modded my tune so I'll get it loaded this afternoon and let you know how it works.

What had me fooled was I went past 3500rpm with them all to no avail., just not all the way out to 4k. All except B1116 which shouldn't seem to matter. I think I might change back the four changes one at a time and see which one is the culprit.

[JoshH]

I think it's 1115 because I had all of them adjusted already, but I only carried 1115 and 1116 out to 3500 and at 4000 it dropped off. 1116 should only apply when in low range so I'm guessing 1115 is what was causing my problems.
