Hi. I have an AEM UEGO ("30-4110") and an MS3x on an '05.

After almost 40k or so miles the sensor itself died ~6 weeks into a Kraken kit. Hoping the placement of the bung won't make this a trend, but I digress. I have been pondering a Microsquirt with IO module firmware for some additional GPIO (oil pressure, oil temp, compressor housing/pre-intercooler pressure, maybe EGTs, etc). Try as I might, with a linear calibration my wideband itself always reads +/- 0.1-0.3ish. The EUGO has an RS232 output (if I recall) and MS doesn't play nicely with this to my knowledge. To clean up my wiring I'll be building a fresh harness adapter, and figure this is a good chance to eliminate the second half of this Analog-Digital-Analog-Digital setup.

Are there any MS-CAN-implementation-friendly wideband controllers (preferably not as finnicky with LSU sensors like the Innovate LC2)? If you have a setup like this, what do you have and how do you like it? What's the refresh rate like? Any problems?

 

The spartan 3 wideband controller has a CAN output that is compatible with ms3. I have a friend with a spartan 2 and he's been pretty happy with it (No CAN output though). The AEM X-series gauges have an AEMnet output that you can use with the MS3x as well, but I believe enabling that doesn't allow you to use any other CAN devices like gauges, digital dashes, etc. There used to be an MSLabs board that you could use to convert the AEMnet signal to the standard MSCan signal, but AFAIK it's not available anymore. I could be wrong on that though.

 

Ah ok. The MSLabs stuff - I thought that was a MiataTurbo developed WB controller using Bosch ICs but I have trash memory.

The not-Lite Spartan 3 w/ LSU ADV looks like a bitchin' deal - I like that option a lot! I remember hearing positive words in other threads about 14Point7 products so I'll almost certainly go that route. I like that they openly tell you the 10ms response time!

 

It's my understanding the the MSLabs board converts the serial output from your wideband controller (AEM, Innovate, whatever) to a CAN signal. I haven't actually used one though, so someone may be able to correct me if I am wrong.

Yeah, the Spartan 3 seems like a pretty solid unit, and I've heard good things about their other stuff. I'm tempted to replace my AEM gauge with one, since I am trying to run a CAN gauge and I don't really need the discrete AFR gauge. I saw they added this recently as well which should help with sensor life:

 

I have a Zeitronix ZT-3 CAN in my MSM along with a Can Checked guage and an MS3. All work together great. No complaints.

 

FINALLY! I have been wanting someone to do that for years. It would be beneficial to add something like RPM>500 and t>xx sec, as it would account for the exhaust condensation being evaporated. I may sell my (brand new) AEM to go that way.
