Recommendations needed for Lambda Controller for Micosquirt
 

After three failed 14point7 lambda controllers including two DOA units that all, based on the 14point7 support forum seems to be a common failure I've completely lost faith in this product.

I'm looking for a replacement controller that will work with the standard Bosch LSU4.9 sensor.

Just looking for a bare bones controller with a linear output that is small and can be installed in the engine compartment.

Thanks

I replaced my Innovate LC-1 about two years ago with an ALM-ADV. It uses a LSU-ADV sensor which is supposed to be faster and more temperature tolerant than the LSU-4.9. The controller uses the Bosch chipset to complement the LSU sensors. Not many people use this brand, I thought I would give it a try. The output signal is much more smooth (in data logs) compared to the LC-1, which seemed to have a lot of noise. It also appeared to respond quicker than the LC-1. The electronics for the ALM-ADV are mounted in an aluminum box with connectors. I had them assemble mine with ALM-CAN box which is smaller, to ease mounting in the engine compartment.

I checked the ALM website and they now offer the ALM-INLINE, which has a small inline package to house the electronics just like the LC-1 had, making it easier to mount. It will also work with the LSU-ADV sensor. So, you can check it out to see what you think. Otherwise, a lot of people use the AEM wideband controller.

I have the innovate mtx-L.

I haven't been the happiest with it and their tech support aren't nice nicest people to deal with.

I've been looking at the units from 14point7.

My experience with 14point7 has been less than stellar, and seems to be common. I would consider other options.

I typically use the Innovate LC-2. Any of the WBO2 controllers are sensitive to electrical noise. Make sure you have clean input voltage.

I have an innovate LC-1 that's from my old evo from 2006 and still going strong, though I did replace the sensor. I have an extra MTX-L plus that is brand new if you're interested.

I completely zoned out and didn't read that in your first post...:confused:

I've used a few over the years and have been very happy with the NTK air fuel ratio monitor. Much less glitchy than the innovates and others. I prefer to use the NTK sensor version as well, they do seem more robust than the Bosch LSUs

I installed the innovate LM2 several years ago adding the wiring for monitoring boost, control pressure, voltage and a/f ratio. Later I added innovate AF dash gauge which is wired to the original unit and gives better visibility. I don't think I have used the large monitor since I mounted the gauge, it just rides next to the console if I ever want to mess with it. I'm not a big fan of innovate but it all continues to work and I haven't seen a product with enough fans to make me change.
I'm not sure why they call these a/f controllers when to me they are just monitors.
The best improvement to all of this was when I added a control pressure gauge to the dash and another under the hood which makes CIS much easier to monitor and adjust.
