Innovate LC-1 Wideband sensor

The AEM wideband can indeed give feedback to an ECU via a 0-5v output indicating between 10 and 20 AFR. I don't know what the Megasquirt needs but I'm sure it can be adjusted to work if needs be!
 
Everything is done inside the gauge, the sensor plugs into the back and there's an additional tail for input power and the 0-5v output.

How I wired mine in was to take the 12v input from the same 12v source as my AEM ECU and I also used the same ground, to try and keep it all as "together" as possible - that means the 0-5v signal wire will be right there with your ECU so it should be easy.

The connector block for the sensor is absolutely huge by the way, and the lead on the sensor isn't very long which did limit placement a bit. The connector itself is well insulated from the elements. I chose to hide mine in the transmission tunnel area somewhere around the gearbox and fed the gauge-end connector up through a handy hole on the firewall...

Mixed opinions on the web... Some say the sensor wiring can be extended... Others say that you can't... I might end up having to go for an LC2

My LC-2 has been completely trouble free so far.

Reverent also builds the MS2 for the MX5 to read from the innovate stuff from the serial port so I only had to run the wiring for power
 
Reverent? Yeah I went with the innovate purely because everyone in the MS world seem to like it, I guess you're on an LSU 4.9? Seems the 4.2 is the problem... All of the pinouts on the controller seem to do what I'd expect. I think first off I'll try a new sensor... Take it from there.

Reverent is a Greek chap who builds Megasquirts for MX5 with full plug and play ecu connectors. Yea the LC 2 uses the LSU4.9

OK so I checked the controller... Seems pins 3 and 4 should provide 12v for the sensor heating... There's nothing. Looks like the controller is dead. Would you agree?

If the controller isn't outputting 12v then there's obviously something amiss. Whether it can be fixed easily or not, I don't know.

As for extending the sensor cable - it is quite long between the gauge and the connector. Then you've got a cable which is captive in the sensor and goes to meet the gauge connector. This cable is short.

I can't imagine that extending it (gauge to connector cable) properly with appropriate cable would be too difficult. I wouldn't have thought the increased capacitance or resistance would affect the reading too significantly over the sort of lengths you'd see in a car application.
 
Well as it is, I'm waiting for a response from innovate... Hopefully they'll be of some use. Anybody got a UK contact for them? I'll be much happier once I pinpoint what has failed.

Failing that I'll look at either the LC-2 or the UEGO route...
