Thread: Innovative lc-1...........

Ok I'm thinking of buying an innovative lc-1 wideband with the guage that comes with it but I'm wondering would I still need an safc2 or could I do away with it and use this unit to tune my car as well?

you will need some way of making changes to the air fuel ratio. Start with a fuel pressure regulator. It is a nice tool to have. Get a fuel pressure gauge from summit so you can make quick adjustments.

The safc will work well too as long as the LM1 will allow you to do datalogging to make the best of the guesswork.

But isn't that what the computer software that it comes with is for?

The LC-1 is capable of data logging via connection to PC. Although, the downside is that I do not think you can plot the A/F ratio vs RPM since there is no RPM wire for the LC-1. There are more innovate units that will allow you to do so, but you gotta buy them haha. They are nice too though because you can also do other things with them.

Also, it's Innovate, not Innovative

And yes, you do need some form of management (ie, SAFC) to make much use of the wideband readings.

Ask me if you have any other questions about it.

Oh ok thanks. So in my case, which wideband would suit me best because I already have the safc2 and I'm just looking for a cost effective air/fuel ratio reader (the ones that say like 14.1, 12.4) know what I mean?

I have used the Innovate! LM-1 for years on a number of vehicles and find it to be very reliable. Remember that you will need a suitable bung welded into your exhaust (pre-cat) to mount the O2 sensor.

As Danja said, the LM-1 comes with a black box that can log data and the software to load the AFR data (like 14.1, etc.) to a PC and do a bunch of stuff with it. There is also an Innovate! Forum that is pretty informative. I have no experience with the permanent gauges that Innovate! sells.

As Danja said, the basic Innovate! set up will not relate AFR to RPM, it will plot the AFR against time in seconds and minutes.

To bring RPM into the picture, you have to buy the Auxiliary Input accessory. I also bought the inductive hook up to take RPM signals from a plug wire and feed them to the Aux Input convertor, but I could never get this to work. So, I pull RPM from the same wire that feeds info to my tach. I also pull Throttle Position Sensor in volts and MAF voltage as auxiliary data. I can plot all of this (RPM, AFR, TPS, MAF) against seconds. I can overlay runs and can plot AFR against RPM the way that you usually see it done by a dyno.

You can see some examples of plots in this thread:

Ok so it looks like im better off buying the lm-1. Now as for the rpm auxillary input accessory, is that peice really expensive? I would check on there website but don't even know what exactly I'm looking 4. I'm very new to all the fine tunning and stuff. And I really appreciate the help and input everyone is giving me.

I have a DB digital gauge with mine, and it works fine, and I like having the permanent install instead of just using the LM-1 when I need to tune (this way I can always keep an eye on the ratios). However, the LM-1 has more capabilities and can be used on other cars. More expensive though!

Oh ok so Danja, how do you adjust your fuel ratios throught your rpm ranges with the lc-1?

I just checked in with the Innovate web site. They are now selling an LM-2 that has more functionality than the LM-1 but appears at quick glance to be set up for OBDII systems. It's not clear what they are dong to support OBDI systems, and I do not know if you are OBDI or OBDII (1995 or later, I think but am not sure). So it looks like you've got some investigating to do.

Tell us what you find and we will try to help interpret.
