Toyota Tacoma VE Table?

I'm curious to know if there is a potentially undefined VE table? I'm observing a truck running the stock air box/MAF housing showing rather large error in WBO2 vs PE EQ/commanded values at higher load/rpm leading me to believe a VE error is present due to much higher than stock boost this truck is running.

There are tables i have yet to add to the editor that are used in the load calculation.

Thanks for taking a moment to reply! I'll be looking forward to those additions. Please advise when a new VCM Suite is available with the updates. Appreciate the continued support.

Possibly if you have higher than stock boost it's over-running the MAF. Potentially modify the MAF tube and re-scale the MAF transfer function 41x1 to suit.

We're still under the MAF limit, though close. The problem I'm seeing is that the ECU isn't able to match the PE EQ commanded values, and under high load is off significantly. 11.3 commanded, ~13.0 observed.

Even on my personal truck which just has a Y-pipe + exhaust, I'm seeing a ~1.0-1.5 AFR discrepancy.

Both vehicles running stock airbox.

Did you get this sorted JustDSM?

Not yet. I still have the ticket in with HPT to get these defined in the VCM Editor.

That's interesting.

Hi Chris.

Any word on these tables? They’d surely be a big help with an overboosted truck I’m working on.

Thank you,

Jake

Any progress or updates on these Chris? We?ve got a few folks having some issues around 3.5 g/rev where trucks are drifting far leaner than commanded (Air Load falling from ~150 to ~120) despite measured airflow continuing to rise.

Seems like right around 3.5 g/rev and 4500-5000rpm the calibration could use some correction to Air Load values.

Thanks!

Submitted a ticket (#74423) 3 months ago on this subject with no update at present.

Any word on these tables? just wondering? this thread is about 5 years old and reading through the posts it was supposed to be on the "to do list"
