Thought I'd see how many others are using these successfully and get some discussion going.

I've been trialling TorquePro "Pro" over the last few days. Still working my way around the setup, GPS and units reported.
I do recall someone posting output from Dynolicious - but that's seems to be in another price range - ie: it costs more than $5

I've been playing around with it for about a year now.. along with several other members. Nice little program. Showed 11 hp increase with my Eurocharge tune.. and have a base line on my Avalanche now just waiting for me to get my exhaust bolted up.

I'm not one to run down to a dyno.. so this is a great way to check improvements over "dang it feels faster".. LOL Oh that reminds me.. guess I need a zero to 60 run..

 

It's a good little app and inexpensive. No AFR readings on our cars though.

 

I got a/f ratio with torque,you have to use the o2 voltage readings and convert it over,after going from a single intake to dual my voltage went to a .1 which is pretty lean at wot

 

If you have time, could you elaborate how you do this?

 

Ok I have torque pro so with your car running and torque active you can scroll thru all the sensors that are active,you will see o2 sensor bank 1 sensor 1 and o2 sensor bank 2 sensor2 ,I am using the readings from the sensor downstream which are sensor 2 on both banks or left/right side of engine.I added a gauge to my torque display that read the o2 sensor with a range from .1 volts to .9 you can change that also but theres a conversion chart that converts this voltage to a a/f ratio and I know .9 is something like 14:1 and .7 is something like 12:3 which is where I was,hope this helps or someone with more knowledge chime in.

 

You rock man. I will try this. Thanks. Where did you figure out the conversion chart from?

 

this will be way cool if it works.....
I'll post some data grabs from mine soon....Torque reading seems a little on the low side when calc'd off actual acceleration....

 

Google is your friend.. LOL.. here's a little tid bit..

DIY Air / Fuel Ratio Meter

 

Actually my car is running on the rich side .95 to 1 volt is 12.0/1

 

Hmmm.....not sure I got some dice this end.
Bank1 Sensor2 - readings
Bank 2 Sensor2 - nada

Charts attached....

 

I never seen those types of charts on torque,but looks like you are rich at wot.

 

Actually something like 13.2 to 12 a/f google a o2 volt to afr chart but I wish I could post my gauges but i am getting readings from both rear o2 sensors

 

yes - sorry - I save to csv and bring the log files into Excel for data.

Yes - applied the sirocco conversion numbers and reattached charts.

yes - still ~12 AFR at 6,000rpm

Also pulled in calc. fuel consumption from TorquePro

 

Here is the chart from the link Miata posted. I can't wait to try this.

Voltage (O2 sensor reading on Torque) - Conversion to AFR

0.97V - 12.1:1 - Very Rich - Forced induction and nitrous. you might want to be around here.
0.88V - 12.7:1
0.78V - 13.2:1
0.69V - 13.8:1
0.59V - 14.4:1
0.49V - 14.9:1 - (Stoich- pretty close to 15:1, this is where NA motors should be at)
0.39V - 15.4:1
0.30V - 16.0:1
0.20V - 16.5:1
0.10V - 17.1:1 - Lean

 

Okay gotta ask.. sensor 2.. post cat isn't it? If so shouldn't you be getting data from sensor 1 .. pre cat?

 

Yes - Thought about this myself...sounded kinda weird looking at Cat2 - but the figures indicate precat - ie: there is still O2 around.

 

The correlation I picked up through Excel for these numbers is....
AFR = -5.6833 x Volts + 17.673

 

here's an interesting one of ManiP from my 30min weekly "squirt" up the mountain.
I thought the psi was all out until I checked it against throttle position.

 

I used the boost gauge also on torque now the boost i am weary about but a boost gauge was install and remove and the both torque and the boost gauge was very close 19.5 on gauge 19.7/20 on torque on a 30 degree night 19.1 on a 70 degree day,and this is with a 17lb pulley which appears odd.I do after the nw manifold dcai and high flow filters.
