Calc.VET: correcting MAF and calculating VE (in single log)

[Frozen WS6]

Cool.

For now I would leave that Calculated Pid DYNAIRTMP alone. If you do a log or if now your OS still comes up with a big red X for DYNAIRTEMP.DMA..then we will have to add it and also substitute the Calculated Pid into the CALC.VET formula.

All of this can get pretty tricky. One parenthesis or bracket missing can be a nightmare figuring it out.

Refresh my memory. Analog wideband or Serial?

Once we know how many more steps we need to take, I am hoping to do it with one unified calc_pids.txt (now that you know how to do it). How many Pids now show up on your Scan Tool?

I can do an idle and no load log. But I can't drive anywhere until late April. When the snow melts. But I want to be ready to go as soon as I can. That's why I'm trying to learn more now. lol

I'll have to plug it back in and see, I also have a red X on the BEN from Serial Wideband 1. It's a 98 ta with stock pcm if that tells you anything. 24 pids selected and only two with red X's.

I have a dynojet wideband 2. It says the inputs are analog 0-5v. Outputs are gauge driver 0-5v analog and Calibrated AFR 0-5v analog.

I just checked table B4901 for a 98 Firebird and it looks identical to a 98 Corvette. I'm pretty sure he will have to use the Calculated DYNAIRTMP.pid as the DYNAIRTEMP.DMA will not be available.

Thanks Ninety8C5. I just tried your Calculated DYNAIRTMP and it works quite well. I got no lag on it either. Maybe all the Calc.Pids are working better now...

Frozen, I think it is just labeling that is creating a problem with your Wideband Ben (you are Analog not Serial). Unless someone else volunteers it might take me the afternoon here to devise an Analog Wideband using the Calc.DYNAIRTMP in place of the DYNAIRTMP.DMA in the CALC.VET formula.

Even if you don't use it until April, its good practice for me. I'll check back with you later today..

Cool Thanks guys. I have the same wideband in my 2001 TA also. So I hope to finally get a tune into it this summer too.

O.K., Frozen I think I have it. I checked this method and it was within 1/2% of the original CALC.VET Formula.

Attached is a calc_pids.txt that should work. But, you need to drop (click off) the following Serial Wideband Pids:

1. WO2AFR
2. WO2LAM1
3. WOQEQR1

Then under the Pid Selection..ANALOG pick the appropriate wideband..Should be BENLC11.

After all that you should not get any red X's.

Overwrite the existing calc_pids.txt (Hit Save AS under User Configuration).

[Frozen WS6]

Ok. So I copied and saved as twice just to make sure. Lol unselected those 3 Pids. Selected the analog Ben_lc11.
Plugged into my car and validated Pids.
Now Ben_lc11,
Ben from analog wideband 1
Calc VE Table
Dyna Air Temp
Are all x'ed out.

Shawn,

Where did you get the values for the Calc.DYNAIRTMP.pid ? The ones in your Calc.pids,txt file don't agree with table B4901 for a 98 Firebird/Corvette.

The values in my file are:

*CLC-00-054
C -18.0 116.0 0.1 "{SAE.IAT.C}+(({SAE.ECT.C}-{SAE.IAT.C})*lookup({SAE.MAF.gps}, 0.0,0.600098, 10.0,0.171387, 20.0,0.128418, 30.0,0.085938, 40.0,0.081055, 50.0,0.071289, 60.0,0.062012, 70.0,0.054688, 80.0,0.047363, 90.0,0.042969, 100.0,0.042969, 110.0,0.042969, 120.0,0.042969, 130.0,0.042969, 140.0,0.042969, 150.0,0.042969))"

Frozen, here is what you need to do. Remember we don't have DYNAIRTMP.DMA anymore (your OS does not have it). You have to choose CALC.DYNAIRTMP. Once that Pid is enabled, then you choose CALC.VET..not CALC.VE.

O.K. this one should be applicable.

Frozen, Analog users still need to pick all the applicable Analog Wideband Pids. If you right-click on any Pid, it should tell you what other supporting Pids are required.

Thanks Ninety8C5. I think I had utilized the LS1 Look-up Values to verify. Got the wrong one..Tnx again!

Good job guys

Also remember this: the calc_pids.txt file needs to have at least two blank lines at its end.
