I'm looking for some more information about the data logging capability of the LC-1 wideband from Innovate. I know a few people here have them. Are you using their Logworks software? Does it log RPMS and if so where does it grab the signal from? Thanks.
There is a plugin that you can use with the diablo and lc-1 that allow the data to be viewed in sync. Unfortunately its still being worked on and has been for awhile. http://www.innovatemotorsports.com/forums/showthread.php?t=7548
Yup - I'm not sure that's EVER going to work. Unfortunately, I can never get my laptop to read the Innovate and the Predator at the same time. So I can't get any data synced up.
Jmatt, Are you dyno tuning for your big nitrous shots? or logging AFR separately and then manually comparing them? I'm trying to decide between an Innovate wideband that I really like and the Zeitronix unit that I don't like as much but appears to log better than the Innovate.
If you are going to use the wideband to tune, do not get the LC-1. Its really only good to monitor your AFR til innovative fixes the plugin.
Dan, I watch my A/F Ratio on the Innovative and adjust my WOT A/F Ratio. What is wrong with the LC-1 to tune? Do I need to do something different? Jon
Not really. What you really want is integrated logging but no one has a complete solution at the moment. PLX almost has all their stuff (or they just got it all done). You want a/f, timing, knock retard, rpm, (current gear is a convenience if they do Chrysler PIDs or you can deduce that from vehicle speed and rpm), load/throttle/map, and then maybe ECT, IAT, oil temp, and EGT. That means integrating your OBDII parameters with an a/f wideband and maybe an EGT wideband. Right now you're sort of stuck with eyeballing the a/f at different rpm ranges and then looking at the timing and knock retard separately. If you have the capability to modify things like the VE table you'd want to match up the a/f readings a lot closer. that's my understanding anyway. Dashdaq may be a current solution. OBDII scanner that accepts a wideband 0-5v input. I think Skye is going to get one of those so we'll see how that works. PLX *may* have all the pieces. You would need a SM-AFR, display module, OBDII module, logging module. I think. DashHawk is actively working on their adaptor to accept a 0-5v wideband input. Diablo is "partnering" with Innovate so that solution (if it ever happens) may be specific to Predator/Innovate.
You are adjusting with the handheld and eyeballing the wideband. Not very precise, it will work though and Ive done it as well. If you wanted your tune to be of CMR quality and precision, the data from the LC-1 logs is of no use. The tuner needs exact RPM information to adjust your fuel levels exact.
I agree with this. I noticed my A/F ratio isn't exactly precise as I drive around...but when I hammer it, it is within .1 ratio...ALWAYS. I also found my A/F ratio changes as I add or remove fuel at WOT. Should I NOT be changing things here? I don't want to smoke a piston or something not knowing what I am doing.
I don't think you should play with it if you don't know what you're doing. That being said: Yes, adding fuel will make your AFR richer (lower number, like 10.8). Removing fuel will make your AFR leaner (higher number like 13.2). I would recommend that you keep your AFR at or below 12.8 at WOT to ensure safety.
I agree. Am I missing something? I listed my AF Ratio at WOT and wanted to make sure if I removed fuel it was only at WOT. I removed fuel, and watched my AF Ratio climb and end up at 12.0 or so to 1 by removing 11.5% fuel in stages... Am I missing something because I want to collect as much info as I can...I do not want to screw something up.
Ya, you are on the right track no doubt. The handheld can adjust fuel just fine, just not as precise as a CMR. When you adjust the fuel with the handheld, you are adjusting the fuel at WOT. Your adaptives will adjust the fuel for your part throttle driving. All Im getting at is the LC-1 is a great wideband but has its limits because you cant correlate an RPM with the logging.
What I told you is correct. I think what you're wondering about is that your wideband just flops back and forth while cruising. Reason for that is that the pcm is in "closed loop" mode. In closed loop mode it monitors the stock narrowband sensors and "hunts" for 14.7:1. Narrowbands will read from about 14.1 to 15.3 or so. That's 0 to 1v on the sensor output with 0.5v being 14.7. If it's on the rich side of 14.7 the pcm pulls fuel until the narrowband reads all the way lean. Than it adds fuel until it reads all the way rich. it does this constantly. This sort of feeds into your long term adaptives. At WOT the pcm is in "open loop" mode and does not monitor the narrowbands. It just uses the long term adaptive and adds a fixed amount of fuel on top of that. It's that fixed amount of fuel that you adjust with the predator. Only effects WOT.
