How do these numbers look? I was doing some data logging with a dynojet wide band commander...This was a 3rd gear only run on the street..

How did you get Maf Voltage to be datalogged by the wideband?

 

jeff when you goin to the track next??

 

You can grab the signal right at the maf (middle wire I believe) or you can get it at the connector on the pass side to the ECU. I put it on Analog 2. the only downside is hardware logging only supports Analog 1 so you have to use a laptop to log both

 

lean that puppy up a bit..

Rich

 

Looks safe and sound
You might be leaving a little power on the table though.

 

Like Rusty said you can log analog 1 with your maf V and also a/f and rpms to internal memory. I picked up my TPS and Maf V at the pcm harness...Nice and neat and out of the way... Internal holds about 10 minutes of data.. You also have to put a switch in to flip when you want to log. Analog 2 needs a laptop to log...With those 3 inputs that I logged your tuner can just about get your tune dead on right... This is with a DYNOJET wideband commander...I'm not sure about the others..

 

Soon...I had to get my chit straight..

 

Thanks for the guidance... guess I have to look at the dynojet wideband directions closer to see where on the unit to add the analog 2 input.
I've got the switch wired in so I can log without the laptop. Getting Maf voltage, wow that's cool...

BTW: Since you're at 11.7:1 @ 5400 rpm, I'm guessing its a nice safe tune but you could lean it to 12.1:1 and still be safe and pick up a few extra hp like everyone else said.

Thanks for the help!

 

Here is some info on that second input...from http://www.widebandcommander.com/
quote"The Wide Band Commander is now capable of reading (2) analog inputs. If you have a unit with a serial number higher than 040604006965, you’ll be able to take advantage of some new features in the latest software release. These units are easily identified by verifying the presence of a yellow wire running along side the orange RPM input wire. Your kit may have included and extra length of yellow wire with a terminal end, this is designed to plug into the 2 pin connecter that houses the orange RPM wire.

The analog channels can be configured to show Throttle Position, Voltage, or User Defined Custom Values. The user defined custom analog input setting is designed to develop transfer functions of voltage vs. output values. Be sure to download the latest tutorials for a demonstration. You can also download the “WBC Sensor Calculator” to automatically generate a custom transfer function for currently supported sensors.

Common uses of the user defined custom setting would be for showing boost or fuel pressure. Let us know if you have data on a sensor that you’d like to use and we’ll add it to the “WBC Sensor Calculator”.

If you would like Dynojet to modify your Wide Band Commander to include the second Analog Input, click here."

 

The origional WBC only had one analog input. The update provides for 2 now. Regardless, the memory limitation (internal) still does not allow for hardware datalogging on the second analog channel. You can datalog it with a computer connected. This was confirmed by dynojet over the phone.

yep that is what Dan from dynojet told me too..."
Jeff, are you trying to log to the "internal memory"? Analog #2 is ignored during internal memory logging sessions, but it is recorded during software logging sessions."

 

JeffsLightning and blown318 are you going to 41 on the 28th?

 

I'm going to try and make it....

 

do you remember which color you connected to for the maf? my maf connector has 4 wires.
