EEV-IV TQ and HP Monitors (TQ_NET/TQ_OFM)
Posted: 2021 Apr 23, 12:45
I have been attempting to get accurate results using the Monitors for HP and TQ, but the numbers are way off.
Same with the history tables for N_TP_RWHP_EECIV and N_TP_RWTQ_EECIV.
The main problem I have is that the output in the history tables, only shows RPM at 2000, does not move up the RPM scale.
On another note, I believe I have found the EEC-IV "Net engine torque into transmission, ft-lb." for A1C.
(I say believe, because I use KID2, similar but different).
- TQ_NET = Net engine torque into transmission, ft-lb.
- TQ_OFM = Transmission input torque, ft-lb.
Ram address 0x[35f] = TQ_NET
Ram address 0x[32e] = TQ_OFM
With a bit of fiddling, I have the monitors graph of N_TP_RWTQ_EECIV, overlaid on my TQ_NET RPM - N vs TQ NET graph, and the lines are very similar shape.
Red is TQ_NET.
Yellow is HP.
Green is RPM.
Light blue is RWTQ_EECIV
Anyways, might be simpler and more accurate to log the raw TQ_NET from ram, rather than having to compute it in the ADX.
Forgot to mention, not sure if this works for manual trans.
