Scott Posted November 7, 2011 Share Posted November 7, 2011 I've PM'd Ryan about this but he is a busy guy so I thought I would put it here as well to see if you guys could help me get my head around this... I currently have the following AFR gauge, Wideband controller and O2 sensor... http://www.innovatemotorsports.com/products/db.php I'm getting the Syvecs S6 ECU and Ryan recommended fitting a lab grade O2 sensor for the ECU. Now, what I want to do is only make use of the lab grade O2 sensor and somehow get the readings to both the ECU and the Gauge. According to the above spiel the gauge works off of an analogue signal from the wideband controller (the LC-1). Does the S6 have analogue outputs? Would it not be possible to have the lab grade O2 sensor connected to the S6 and then have an analogue output from the S6 set to send the wideband signal to the gauge that I have? Any other suggestions? I have no idea if the O2 sensor I have is compatible with the LC-1 or whether it would be totally redundant now or not.

Scott Posted November 7, 2011 Author Share Posted November 7, 2011 Ok, before I hit the bottle..... Not sure if this is of any importance but the original O2 sensor is a Bosch 5 Wire, the one I got from Ryan is a 5 wire also. The analogue input to the gauge is 0V=7.35AF to 5V=22.39AF. From the above I would guess that the lab grade O2 sensor would work fine with the LC-1/gauge, what I don't know is whether the analogue output from the LC-1 would be good enough for the Syvecs to monitor with as I'm guessing there is a lot more information that can be monitored via the O2 sensor than a 5v analogue line can provide. Ideally I would connect the Lab O2 sensor to the Syvecs and the syvecs would output the 0-5v signal for the gauge. *fingers crossed* Quote Link to comment Share on other sites More sharing options...

FOSTA Posted November 7, 2011 Share Posted November 7, 2011 Your best bet would be to wait for Ryan mate. He has helped me with my O2 problem. But I would think it would be possible to wire it to the s6 ;-) Quote Link to comment Share on other sites More sharing options...
hodge Posted November 8, 2011 Share Posted November 8, 2011 Hey Scotty. I'm only using 1 sensor. I have an AEM wideband and use the output wire on the gauge to the ECU. I've also binned the stock narrowband sensor too mate. I've mounted the sensor in the midpipe so it's out of sight. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted November 8, 2011 Share Posted November 8, 2011 When I got mine it was only running a wideband (AEM Uego) with a simulated narrowband to the ECU . Quote Link to comment Share on other sites More sharing options...

I've also binned the stock narrowband sensor too mate. I've mounted the sensor in the midpipe so it's out of sight. Yeah the stock narrowband is gone mate. Do you think that the S6 would be able to give the output to the gauge rather than the other way around? I'm just worried that there is a lot more to the O2 sensor than a 0-5v analogue signal can give. When I got mine it was only running a wideband (AEM Uego) with a simulated narrowband to the ECU . I'm pretty sure the S6 needs a wideband reference but I could be wrong. Quote Link to comment Share on other sites More sharing options...
johnny g Posted November 8, 2011 Share Posted November 8, 2011 Put the Wideband in the downpipe, then the sensor runs a line to the Syvecs and an output to the gauge. You can run without the gauge and the Syvecs will still get the signal. To output from the Syvecs, you'll be needing some kind of CAN Bus output (e.g. the JTInnovations Syvecs CAN gauge). The S6 does need a Wideband reference for the closed-loop running. Quote Link to comment Share on other sites More sharing options...

I was kind of hoping the syvecs would have an analogue output or 2 Quote Link to comment Share on other sites More sharing options...

Scott Posted November 8, 2011 Author Share Posted November 8, 2011 http://www.syvecs.com/s6gp.php According to the brief spec there it has 2 5v sensor outputs. Hopefully I can use one of those. Will wait and see what Ryan says. Cheers folks. Quote Link to comment Share on other sites More sharing options...
Hellstrom Posted November 8, 2011 Share Posted November 8, 2011 cant you just connect the wire(s) from the sensor to both the gauge and to the S6? just using some wire and crimp? Quote Link to comment Share on other sites More sharing options...

I thought about that but I was worried about the signal being effected by the splicing. I'm sure I put that to Ryan a while back and he said it couldn't be done.

Hellstrom Posted November 8, 2011 Share Posted November 8, 2011 (edited) Might not be worth the risk, but the gauge itself is driven from +12volt and the signal that is 0-5v should not be effected. I used to have a PLX unit and it had outputs (wide and narrow)from the gauge itself to be linked to a ECU dunno how the wirering shematics to the S6 is tho as mine was only able to Logg wideband and only use narrowband for actually closed loop control. Should be fine if using a shilded wire. but then again if Ryan says its no good then i would't do it Edited November 8, 2011 by Hellstrom (see edit history) Quote Link to comment Share on other sites More sharing options...

The gauge itself only takes the 0-5v signal from the controller. The wideband controller takes LOADS of information from the sensor that isn't sent to the gauge, I'm assuming that the S6 takes the same information from the sensor so only sending the 0-5v analogue signal to the ECU wouldn't be giving it as much information. The problem with splicing the sensor line would be voltage drop I would have thought? Surely splitting the wires to 2 controllers would half the signal strength to each one?

Hellstrom Posted November 8, 2011 Share Posted November 8, 2011 Okay well my controller was built in the gauge itself. Well aslong as you dont add resistence the volt will be the same. so using a 99.99% copper cable should not add any resistence afaik. i still think tho if Ryan said he wanted the wideband to be for the ECU only thats the way to go. however i dont see any problems using the signal for both the gauge and for the ECU.

Golfpro Posted November 8, 2011 Share Posted November 8, 2011 There are two seperate output wires with the LC1. Wire one to the gauge and one to the ECU. Quote Link to comment Share on other sites More sharing options...
