Is there anyway to feed the wideband analog output signal from the Innovate LC-1 wideband o2 sensor to the Perfect Power SMT6 so I can get an integrated datalogging or do I need to use 2 serial ports and log from the SMT6 and LC-1 separately ?

Send the narrowband output from the Innovate into the narrowband input of the SMT6.

I haven't looked at the SMT6 in a while but I'm pretty sure it has an input for a narrowband O2.

You could give it the wideband signal also, but I'm not sure it will convert it to a/f.

Yes you can, however you will not get the details as you get on the WB system.

Thanks, yes, the SMT6 has a narrow-band input but I want a way to capture the wide-band output of the lc-1 and log the voltage levels in the SMT6 datalog. I don't need the smt6 software to convert to a/f - I can do that manually.

That said, I guess I could adjust the LC-1 wide-band signal range to match the expected narrow-band range of the SMT6 and connect the wideband signal to the narrow-band input and get the voltage level captured. The narrow band voltage range is 0-1V. Anyone try this ?

Send KevinCNC a PM. He's got his SMT & innovative set-up logging together in the SMT and it works great. Actual AFR is displaying on the SMT-6. I'm dumping my Zeitronix over it.

nooooooooooooooooooooooooo

Brad, you can log the 0-5V wideband output. You can email me or email KevinCNC, I went through this procedure with him. If you have the black SMT unit, it'll be a bit tougher, the newer units using the Vitesse only software are easier to deal with this. Regardless, if you need help, I'll be glad to assist you.

Thanks John - I'll contact you if I need help. Good to know it's possible !

I have the latest Zeitronix with the linear narrow-band output (which is just the linear 5v wideband output rescaled to 1vdc range). I connected this output to the SMT6 in lieu of the factory O2 sensor. Seems to be working fine with no fuss... Am I missing something?

fast951

Tom, You can log BOTH th e01Vdc and the 0-5Vdc wideband outputs. The 01Vdc simulated narrowband can be logged by connecting it to the O2 sensor inoput (as you did). To log the 0-5Vdc signal, it's a bit more involved.

Brad,
The LC-1 has two analog outputs. You can use the LM Programmer software to program either one for Volts/AFR. I use one for my analog gauge and set the other for 0V=10:1 AFR and 5V=15:1 AFR to make it easy to read on the piggyback without having a translation table. Wire the output from the LC-1 to one of the 0-5V analog inputs on the SMT-6. From there I don't know what the differences between the Vitesse and standard SMT-6 software are. In the Vitesse software you click the "Setup Display" button, and turn on Advanced Settings. On the line that I wired into, I named it "WB AFR", and checked the box to turn the line graph on also. You can set the Min/Max voltage values that are displayed. I found that 0V for min and 5V for max is a good range to start with because it shows 10:1 to 15:1 AFR. You can set it to whatever is best for what you're trying to see when you play back a log file. Since I want to be at 11.7:1 at WOT, I like to set the display for .7V min and 2.7V max. Then at 11.7:1 AFR the line graph should be centered vertically. That makes it easy to watch the graph as you play it back and adjust the cell that it's in to get the line as flat and centered as possible.

Kevin - excellent information - thanks !! I've got the LC-1, just need to find a spare Saturday to put it all together - thanks again.

What analog input on the SMt-6 did you guys use for the wideband signal ?

porschefig

What wire would you use to get a WBO2 signal from a Zeitronix ZT-2 for a MAFterburner piggy back?

Dave951

I have the same setup and want to do exactly what you're trying to do with standard software. After you get it going if you could put up the steps you took to make it happen that would be awesome :-)
