Default Who's running AEM UEGO with MSI? Versus LC1

Who is running the AEM UEGO wideband setup with their MS? Who is this working well for? I'm having some issues with autotune working correctly as well as MLV. Neither work as they're supposed to. Both make my car go dangerously lean, leaving it very undrivable. IOW, lots of bucking and power loss due to the fuel maps being pretty much what I would call destroyed. I have the custom.ini files adjust appropriately and my target tables setup correctly as well. Pretty much no idea what the problem is and i've been trying to figure it out for a good amount of time now.
Is there any insight to this that I might be missing? I've done the code conversion to make megatune read exactly the same AFR as what comes up on the gauge, so that is very accurate. I have also done the code conversion to make it possible to enter AFR values in the target table instead of voltage values.
You can see the Volts to AFR conversion writeup here: http://forums.plastikracing.net/view...?p=52097#52097
The reading adjustment on the same forum by the same guy.

I'm interested in this as well, as i'll be running a similar setup when my MSPNP gets here.

I'm running the AEM UEGO gauge with my MSPNP and I've done the exact same things (code conversion to make megatune read exactly the same AFR as what comes up on the gauge, so that is very accurate. ... code conversion to make it possible to enter AFR values in the target table instead of voltage values.)

When you say MLV you mean the log viewer isn't working right or the VE Analyzer?

I am having no problems using MLV VE Analyzer at all. Autotune on the other hand I have never gotten to work because I've been too lazy to edit the parameters in the code

does what you are seeing for AFRs in the log correspond with what you saw during the logging run?

send me your current msq file and a log and let me see what my VE Analyzer does with it.

I'm interested in hearing any updates about this issue as well as I just sent the money tonight for an AEM UEGO and plan to add a MS soon - are these not very compatible? If so I will return it immediately, I need something that will work with MS.

They work perfectly and I recommend them over LC1s now just because they're easier to use and install.
You have to change the calibration a little to make the AEM and MS read exactly the same but that is easy. The link is in my signature.

The AEM is easier, but also less flexible. I've had both, and prefer the innovate product because it's configurable to every application. The AEM, not as much.
