Well...i finally got it working!



I just modified my Autocal to work with a serial wideband so you can read wideband/AFR and datalog for your tuner to get better information.

This WILL void your warranty on your autocal...but...you have been warned!

The Autocal will only accept serial inputs, but takes some modifying to work, as it is not natively able to do so. however it does have the contacts inside to make it work.

For this, you will need the following:
Serial RS292-DB9 FEMALE soldered connector (http://www.amazon.com/StarTech-com-Assembled-Connector-Backshell-C9PSM/dp/B00066HQBY?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00)

18-22ga multistranded wire

Drill bit or small round file

Soldering iron with fine tip

Silver solder

no. 1 Phillips screwdriver

patience and a steady hand.

So, here is your Autocal.

Here is the backside of the autocal. You will need to use your screwdriver to pull all 5 screws out, and put aside. Do not lose them.

When you open up the Autocal, this is what you will see (minus the red and black wires coming out. Those are what you are adding.

To pull the board out of the Autocal enclosure, you will need to squeeze the top of the autocal just a bit and pull the board straight up and out.


Once it is out, you will see RX, TX, VCC, RD and Ground. We will be using RX and Ground. Do NOT attach anything that would put power to the Autocal here. Nothing other than RX and Ground wires.

I used about 6" of red and black wire. Go as long as you want. The longer, the more room you have. Wrap the wire around itself, tin the tip, then insert into the holes/contacts on the GROUND and RX location. Use a FINE TIP soldering iron, and melt the solder on the contacts. When the solder starts flowing remove the soldering iron. You are done here.

Do not get solder across the other contacts. That will cause a short, and could potentially ruin the Autocal.


Next you need to modify the enclosure for the wires to escape without pinching.

Next is the wiring on the serial connector

Again, tin the wire, tin the contact, yada yada.

Once you are satisfied with your wiring, you can sleeve the wiring for a nice clean look, or leave it naked.

Once you are done with that, put the cover on the serial connector, and you are done with the Autocal!


I have this setup for Serial logging with my Innovate LC2 Wideband. As long as your wideband has a serial out, you should be golden.

All that is left is setting up Efilive and the Autocal software for reading.

Happy logging!

I have done this mod to my autocal and set up the serial configuration for the lm2 wb in the autocal settings. I have since changed to an Autometer wb and would like to modify one of the preconfigured wb selections to work with my autometer. How do I do this?

Connect AC to your PC...

go into V8 S&T, goto Devices, set Wideband type to the brand you're now using, save to file, click Program.

The Autometer Pro isn't one of the options to select. I'd like to find the code file that has the baud rate etc. for those preconfigured devices and modify one for my Autometer.

I see, Autometer is not in the pull-down list of widebands...
