Connecting XCal2 to Innovate LC-1

[Bmr4life]

Well, I've decided to skip the XCal2 altogether and replace it with this for datalogging.

http://www.ot-2.com/

It'll be here this Friday and I'm gonna sync it up with my iPad and see how it goes.

Any update on this?

Yep, I've had it for a while now and it's great! I was having a vacuum leak, most likely from a cracked intake as a result of a nitrous backfire. I datalogged fuel trims with it and they were all out of whack, suggesting the PCM was compensating for extra air not incoming through the mass air sensor. I was able to datalog, extract the data, email it and post to a tuners forum all with the iPad!

Here is the setup:

Great, that's quite nice. Their website says it works for PC's also. I'd rather get this than have to figure out the xcal2 configuration.

Is that a bracket for the IPad that you bought or something you fabbed up?

Also, any issues with dropped connections? Seeing a lot of reviews/complaints about that.

No connection issues with me. My wideband gauge and the iPad readout are almost synced exactly. You can connect the OT-2 directly to PC without having the cable issues the XCal does.

I got the bracket and mount here:

So do you need a wideband with the OT-2?

Yes, and it has to be Innovate's...I asked them.

Holy shit they're proud of their brackets aren't they? $$$

You don't NEED a wideband at all if you just want to datalog PID's. But, obviously, if you want A/F data along with those, then, yes, you need Innovate's LC-1 or the newer equivalent.

I got the one to hold the iPad, and another one for the Mustang to clip to the dash, as well as another to connect to the headrest posts in our Flex. They are expensive, but great quality and they fit perfectly.

Lostsoul - ground offsets are nothing magical. It's simply using a multimeter to measure the voltage difference caused by the grounds. You take one measurement and plug that into your formula that gets uploaded into your LC1. If you're not comfortable with doing this, you need to get someone to give you a hand.

I think a lot of people are under the impression that you can buy a WB, plug it in, and that's it - nothing more than another gauge. These things need to be calibrated and setup to work properly. If you don't, it won't read correctly.

Good point...that's what I meant, but not what I type.

ummm.. whats a ground offset? I just grounded what they wanted..haha.. did I miss something,?

It's not rocket science man.... Don't forget to read page 2 as well.

I took NO measurements with a multimeter when setting my ground offset, livelink is the meter . For the lazy people that won't search google here's how it's done.

What I did is I set up my LM1 to read 2.5 volts (no range only a constant voltage of 2.5).

Then I see what that voltage reads in the livelink software usually under analog 1 or analog 2.

If livelink is showing 2.444 volts instead of 2.50, then the difference of 0.056 if the offset.

So the .06 will have to be added into your formula in SCT livelink.

THESE SETTINGs ARE FOR DEFAULT LM1 or LC1 PLUS THE GROUND OFFSET, YOUR WIDEBAND FORMULA MAY BE DIFFERENT.

((V+.06)*3.008)+7.35

Notice where the 0.06 offset is.

The link I gave lostsoul shows how to do everything. PAGE 1 & 2

Yes, you can do it that way. But since he's having so much trouble with things as it is, I figured what I wrote would be easier for him. Wouldn't you agree?

Not really. Reason being that a multimeter may give you the true voltage but what we are looking for is the difference between the wideband and SCT. Using SCT through livelink for reading voltage will give him the exact amount that SCT needs to make the correction. I hope that makes sense.

Furthermore, my livewire can datalog without the need of a laptop and livelink. Using my method for the correct offset will work with the livewire method as well. If we calculated actual offset with the multimeter and used that number in both livelink or the livewire device alone the readings wouldn't be correct. Reason I know this is because I've tired it through livelink and livewire separately and there was a difference. Albeit either way believe it or not was very close. I could have used both without adding the offset to the equation and I would have been VERY close to what the LM1 was reading. For those that are WAY off I think they just don't have the correct formula in livelink (offset aside).

Just for reference

With my LM1 set to 2.50V
Reading from my Livelink was 2.496 Volts (very close)
Reading from my Livewire device only was 2.452 (still pretty close)
