Okay, I need to reread this thread, but are there:

Turbine RPM's?



Could you update the original posting with all the PID's newly developed?

Thank you.

It doesn't seem like the posts were edited. That being said, does it make sense to use the most recently posted .CSV, from page three, at this point?

Good point. I'll try to keep the most recent on page 1.

I can do the algebra if the A and B parameters can be explained.

Thank you all.

Well, you cannot getting readings for anything that does not have sensor.
There are no rpm sensors on the OEM turbos- wish there were.
I believe all the pressures that you need are already in the CSV file.
If you want to do PID math, look at the custom methanol target PID I created. The letters are bits within the data bytes. See the OBD list PDF I published. I'll attach it to the 1st page post.

Can anyone get a Mode $01, PID 6B, bit C, to work.
Formula should be ((C-40)*1.8)+32
This is the ERG Cooler, exhaust temperature sensor.
It works in Testo, but I get no response in Torque.
Thanks.

Thank, DWR! Your PIDs appear to be working great. Is the AFR accurate? At low throttle, it reads 29:1 and does not get anywhere near 15 unless I go nearly 100% throttle.

You're welcome!
That's the cut off for the reading. It actually goes higher.
Diesel's run under a wide range of AFR, unlike a gas engine. The readings are correct.

Thanks for the info. I'm going to take a look at your request for the EGR cooler temp in the near future. I was an embedded systems engineer early in my career but very new to the Torque App. I wish I had been using this years ago!

Where is the EGR cooler temperature sensor and what happens to it if you do the racepipe/cooler removal? Does it stay in tact?

[nicklockard]

I was surprised the 335D runs so rich. ALH series engined Tdi's used to run as much as 250:1 or more A/F ratio's on light load and 35:1 or more on cruising. I'm seeing 23:1 on cruise and 5-7.5 psi boost on cruise. I suspect a boost leak though.

Well, it is in the cooler. So, it depends whether you physically remove it or just block it off. What is great about the alphabet deletes is the sensor inputs can be repurposed. I'm using the EGR cooler temp sensor to measure pre-CACT temps.

Nice. I'd love to see how you got that installed and example logs under various driving conditions.

With it inhaling exhaust in OEM configuration, and using throttle closure to do it, that certainly explains part of it.

Installation was pretty straight forward. Extend the wiring and tap the aluminum compressor outlet piping. I'm away on business. Otherwise I would attach pics.

I have logs but they are not very interesting because I was trying to resolve the Testo vs Torque issue ... then other things started to take up my time - as you know can happen

[f00dstamps]

Anyone here have a BPC Stage II+ that can share what they're seeing as peak boost? I did not log it but I recall measuring just under 33 lbs. I make a lot of smoke at and suspect I have a boost leak.

[robnitro]

If you compare maf reading at peak boost you can see if you have a leak.
But since our maf gets saturated you have to compare at a lower rpm, like 2500 or so.

Ex you have 33psi and 55lb/min maf. But known good has 33psi and 45 at same rpm. Then yeah you might have a boost leak.

But then i heard the ecu does fueling by oxygen sensor, lambda, so wouldn't that limit the power if less air is getting into engine??

That's the thing. I don't know what a good MAF-boost correlation is. I'm not sure how the ECU does the fueling but folks have commented that I may be running rich (in this case probably a boost leak) since I'm putting out so much smoke.

If you add the pids i posted, there is one for maf to rev and per bar calculation. The per bar pressure maf reading should never go above 600, try mid range rpm Max boost, normally per 1 bar our engine takes 500 mg per cyl per stroke

DWR - how accurate is the Torque boost reading with your PID? Was it calibrated against an analog boost gauge?

It is as accurate as the sensor. It is not a calculation. It is only scaled from the reading reported to the DDE. That scale is an OBD standard. BTW, if your analog gauge is in a different location than the MAP sensor, the readings will not be the same.

Thanks for the explanation, DWR!

Robnitro - I am really new to Torque so I hope I am doing it right. I copied your PIDs above into the same CSV file that DWR provided. When I added the gauges and when the car was off, the ranges on the 2 calculations were accurate. When the car started transmitting data, all the incremental numbers went to infinity signs. At idle, the readings are mid 300's. During a slight incline with 5-8 lbs of boost, I can exceed 600. At nearly full throttle and boosting ~31 lbs, it has exceeded 1600. What does this tell us?


Edit: I read through some of the posts again from page 2. I should delete the custom PIDs and reinstall them. I'll test it out when I'm back from my business travel.

If needed I will grab my dedicated cheapo android phone as torque and will post the file or if you want it emailed to you, robnitro AT yahoo DOT com

Thanks, robnitro. I got it working when I reloaded the file and PIDs. Unfortunately I appear to be getting significant boost leak. I get readings of up to 900 when only boosting up to 15psi. I did not log a higher run this time but I've seen numbers of up to 1200 on 32psi runs.

Does anyone know if BPC 2+ disables the NOX sensor readings? I am getting no readings (-100 PPM) on the NOX PIDs.
