So I am logging torque...

[killerbee]

using engtrqref dma. But the logged values are not really matching B1115.

What am I missing?

If I set torque equal to, say 150 ft-lb across the entire 20% throttle row of B1115, then apply 20% throttle, I would expect to see a steady150 in the log. Oddly though, as rpm increases, logged trqref increases also. ??? Then in torque based fuel, fuel increases because of this. So I am perplexed here.

Are engtrqref PID and the values entered in B1115 un-related?

more info:

I limit torque in B1115 to 700. Yet the log is showing 775, and in B1102, I am getting the fueling of the 775 row. It is overfueling.

IOW B1115 does not appear to be an accurate table. Reported torque (thence fuel) does not seem to adhere to it.

HELP!

It's not the torque PID that is the issue it is the throttle position PID on the LBZ, you have to change it to SAE_APP.D I believe is the name of it. Something like that, I don't have my laptop here but you'll find it from that.

Thanks so much, I will give that a look.

I changed to appD,

b1115, at full throttle, commands 500 ft-lb. I capped it at 500.

The log shows about 700 lbs at WOT. And fuel is way high, reflecting 700 ft-lb fuel amounts from B1102, so B1102 is working correctly, but B1115 does not seem to be correct. I am logging 100-200 ft lbs higher that this table is "commanding".

Other thoughts? Doesn't seem to have anything to do with throttle pids.

I've been using TP_A... and i have never limited the torque tables just left them with the mins and maxes.

It is known that there are inconsistencies in the torques values in the tables and pids. However what i command in my tables i get and same goes for torques based fueling too.

Also if you haven't noticed there are also inconsistencies in max values in the tables as well.

Yes. But the table values not being reproduced on logs, is un-nerving. I wonder why I am seeing this. I can probably limit torque with the cieling tables, but that is un-nerving also.

[bballer182]

instead of limiting "torque" why don't you just limit the tq based fuel for for a giving tq reference?

[killerbee]

Through experimentation, I have concluded that engtrqref displays 75 to 140 higher than B1115 values. The more throttle, the higher the disparity.

reloaded the stock tune, and it does the same thing.

Hopefully this is a known bug and it is being worked. I sent logs off to Ross.
