Even so, I wanted to tune my analog guage off of MT, till I found out they weren't agreeing.
You *can* send the LC-1 serial commands but... That would be a pain. Just go find a windows machine, set it up once, and forget it. Run VMWare or something. It is kind a one time thing.

I take it you're running linux? I guess innovate doesn't suport anything but windows huh - but yeah, you only have to change it's calibration once.AbeFM wrote:Even so, I wanted to tune my analog guage off of MT, till I found out they weren't agreeing.

I'm running different things on different machines, but my main laptop for talking to the car is windows - I might not like it, but there is just a lot more software for it. Seems weird in an 'open source' project like this, but it seems best tackled in windows.

And I quote....
Just a little communication break down there... for a year and a half LOL.
Enjoy.
I just tested this and it is true, and does look a LOT better :-)efahl wrote:Ok, so it looks like the extra guys are using an old MT version? I added the LC-1 native support about February-March 2006, so there's no reason they shouldn't be using a version a little more modern...
It's in the p1 installer dated 08 MAR 2006, find it here:

I only started on MS in '07, with the latest MT 2.25 - the error is still there. I don't think we're all that dumb :p6040solder wrote:And I quote....

I'm in the same boat as you, and although he probably did make the change back then, it certainly wasn't well publicised! I got my copy from somewhere in the megamanual too *i think* but I can't remember anymore. Either way, the wrong one has been distributed around the place, and this one definitely works as desired. Whether its what is included in the extra installers or linked from the dozens of various places around these sites I do not know...hassmaschine wrote:I only started on MS in '07, with the latest MT 2.25 - the error is still there.

Er, how do I tell if I have the "good" one or not? The installer dated 8/06 is the newest?efahl wrote:Ok, so it looks like the extra guys are using an old MT version?

I dunno about you, but I don't see the letters L, C, or 1 in your post, does that mean they aren't in your menu either? If not, it's old.AbeFM wrote:i.e. we can pick Innovative 0-5V Linear and it will map to 10-20 AFR respectively, or we still have to manually put it in as a generic?
I can do a pair of screenshots if i have to...

A single screen shot of the right one would be plenty. I'm talking about the TOOLS->Calibrate AFR Table->Sensor Type pull down, which has 16 choices, 3 of which say Innovate 0.0-5.0V, Innovate 1.0-2.0V, Innovate LC-1 0.5-1.5 L
My question is should I select the first choice to do 0V = 10 AFR, 5V = 20 AFR, linear?
Or, am I totally on the wrong page here altogether? Last night I just typed it in as a generic wideband with those settings.

Sounds to me like you have the up to date one.
The older one doesn't have the LC1 0.5 lambda to 1.5 lambda option.
IF your LC1 is as it came from the factory, and you are happy leaving it like that, then you should choose the LC1 option.
IF you want slightly finer resolution and don't mind adjusting the LC1 then you can change it to be the same as the LM1 (0-5v = 10-20afr) with the Innovate software and choose "Innovate 0 - 5v".
Hopefully thats clear enough :-)

that's just it, that won't work. if you run both the innovate software at the same time as megatune, you will see there is a big difference in how they read - it doesn't matter which innovate setting you choose.6040solder wrote:Sounds to me like you have the up to date one.

Hassmachine,
Interesting. That was what I understood from you. Can you tell us how far it is off at a known (LC1 reading)? Which direction or any other points where you are pretty sure of the true reading? From the code, it appears we *should* be ok, but your report says there is still something not right.
And if you configure a 'generic sensor' with the values from the LC-1 (0V=10:1 and 5V=20:1 - in my case) it reads correctly, right?
I want to get to the bottom of this.
