Innovate Motorsports MTX-L Wideband Air Fuel Ratio Sensor/Controller/Gauge

I have not decided on my wideband air fuel ratio (AFR) or O2/lambda sensor but it will be either the Innovate Motorsports LC-1 or MTX-L. Both use the famed Bosch LSU 4.2 5-wire wideband O2 sensor with similar electronics with the LC-1 having the electronics build into a sealed cable whereas the MTX-L has all the electronics in the gauge itself. I do not really need a separate air fuel ratio gauge with my AIM MXL Strada Icon dash capable of displaying air fuel ratio. The MTX-L is the same as the LC-1 but a couple hundred ringgit cheaper as the LC-1 comes in a kit with its own gauge. Go figure..

A proper wideband is critical for the Slowtra's tune and build as the stock narrow band O2 sensor is next to hopeless being only able to tell whether the a/f ratio is above or beyond stoichometric and does not give accurate readings elsewhere. A wideband on the other hand is good for measuring and deriving accurate air fuel ratios anywhere between 10:1 to 20:1 which is a range all modern engines operate within. MotoIQ has an excellent article explaining how narrow and widebands work.

This write up is on the MTX-L as I had initially decided on it only to be not so sure later. Blame the gauge.
Picture of the MTX-L box. The LC-1's box gives me a sense of déjà vu. All pictures were taken @ GT Auto while I slow stripped the MTX-L from its packaging.

Manual and CD-ROM with the software. Both the LC-1 and MTX-L are capable of datalogging via Innovate's Logworks application.

The Bosch LSU 4.2 5-wire wideband O2 sensor. The LSU 4.2 uses a wideband zirconium-dioxide oxygen sensor. Innovates uses a different approach known as Direct Digital to control its wideband O2 sensors. Innovate claims Direct Digital results in a faster response time and improved accuracy over conventional control methods. If you want to use back your stock ECU and just replace the O2 sensor,  Innovate is capable of simulating the operation of a narrow band O2 sensor. Click here to learn how to.

All the electronics and controls are build into the gauge itself. Innovate provides both a black and white face plate and bezel which are interchangeable. Picture below shows black bezel and black faceplate that comes standard. Takes a couple minutes max to swap faceplates and/or bezels.

The Slowtra's new exhaust and associated snail piping are currently being lovingly fabricated and the decision (on which wideband) will be made in due time.

Did you end up swapping out the MTX-L for the LC-1?

Im currently looking between the AIM MXL Strada Icon or the Pista & wanted to also integrate a wideband into the system that would utilize the display, rather than go standalone gauge. In such, currently researching between integrating a LC-1 or going with AiM's own wideband system - LCU1.

The cost is higher by going with AiM's solution - but its a plug & play install which is attractive.

Thoughts? Would love to see a blog post on when it comes down to the install/integration of wideband & other sensors to your AiM!

^ Note: Found this & looks like the LC1 does not do CAN but only RS232. For my application, I will be using CAN so this might be out for available choices in CAN application (?)

Still have not decided on MTX-L or LC-1. Will probably have my engine builder to decide.

I think you might want the MTX-L. Somebody emailed Innovate and this is their response.

"In terms of features both systems will work the same with the your setup. The MTX-L has less wires to install since it is self contained. The MTX-L is also fully digital like the XD-16 but at a price cheaper price than the DB gauge kit.

Well the issue is I don't want the gauge and having more wires is really no issue when one is having a fully programmable standalone ECU which will need much more wiring than any wideband kit.

Hello Sir,

Trust you are an expert in car industry.
I am planning to buy a 2nd hand 2010 Nissan Sentra.
What do you think about NS 1.6 vs 1.8 (auto)?

Which one is better in term of all espect, especially fuel consumption; given 90% of my driving will base at KL.

Thanks in advance for your sharing.
Thank you

Ivan Koo

Andrew Saw said...

Haha! A 1.6 manual! Fuel consumption is easily 10-15% better and power is akin to the 1.8auto. If an auto box is a must you can't do any wrong with whichever engine or spec you prefer.

regarding integration of the wideband reading to the dash, I believe it can be quite easily done if you are running a standalone ecu like Andrew. The ecu has inputs for wideband and the LC-1 can be hooked up directly to the ecu. From the AIM dash to the standalone ecu, it uses a CAN network and all the info from the ecu can be then shown on the dash. The best thing is that the CAN uses only 4 wires and keeps everything tidy between ecu and the dash.

if you want to run more sensors and used up all the inputs in the ecu, u can also got a universal sensor module, which hooks up directly to the dash using can system too. all the additional sensors are hooked up to the USM module and you then integrate these input on your dash. I am using this for my Putra, but with the Racepak IQ3 logger dash

Thanks for the detailed explanation Bro
