  • Finally bought WBO2 for Alpha N

    Just picked up an Innovative MTX-L gauge which is basically the LC2 but in a gauge packge. Anyone try this piece before? I'm really excited

    I had it and liked it. I've since swapped to an analog gauge which I like better. Matches the age of the car better in my opinion

      I have been recently thinking of this as well. I don't have anything fancy, just a Miller MAF/WAR Chip, but it needs a little more tuning to be perfect.

      Reading about the pros and cons of AEM vs Innovative LC-2, apparently the Innovative setup is "more accurate" but requires frequent open air calibration that involve removal of the O2 sensor. If that's the case, then I'd steer toward AEM.

      Innovative MTX-L All-In-One Unit - $209

      Innovative LC-2 Stand-alone WBO2 controller - $189 (separate gauge required @ ~$100+)

      AEM Digital Wideband UEGO gauge /controller/sensor - $221

      You still need to maintain the stock narrow band sensor to keep your stock computer happy, yes? This also means additional cost to weld in another bung.

      The remaining issue is that I don't really need or want a permanent AFR gauge - only to install the gauge when needed and either be able to remove it easily or purchase a gauge small enough to tuck away out of sight when not used.

      This PLX multifunction touch-screen gauge/controller kit - $199

      Priced comparably to the others and seems like a good solution (small/thin gauge that can be tucked away), but I don't know anything about this manufacturer, their ease of set up or quailty.

      Any advice or ideas appreciated!

        Can't speak to the Miller MAF/WAR setup but with a MAXX Alpha N the stock narrow band sensor is scrapped when going to a WBO2 setup with the latest version.

          I noticed this on the PLX page:

          http://www.plxdevices.com/Wideband-O...7346002719.htm

          It includes a Bosch LSU4.9 wideband oxygen sensor. The wideband controller (SM-AFR) works with gasoline, bio diesel, ethanol, methanol, E85, LPG, and CNG. It includes two analog outputs (wideband 0-5V, and narrowband 0-1V) for interfacing with 3rd party devices and one digital serial output for interfacing with the DM-6 gauge and other Multi Gauges. The wideband analog output is ideal for interfacing with aftermarket ECU's and data loggers. The narrowband output is ideal for stock narrowband oxygen sensor replacement where the simulated narrowband analog output is fed back into your ECU to make it operate as if the stock narrowband oxygen sensor is still installed while running the PLX wideband setup. All three outputs can be used simultaneously. Additional features include advanced soft start technology which prolongs the oxygen sensor's life and an aluminum enclosure for durability and reliability.

              I installed the AEM UEGO last week. Very easy installation and no need to calibrate the sensor.
              On idle and on full throttle the ratio is ok (or little rich) but on partial load it is lean. Is this normal? My setup is 215hp head with 48mm TB's and 276/268 Schricks and the 091 ECU
              When cruising it is so lean the gauge is not sawing anything cause it is above the capable ratio 17.0

                Been using the NGK AFX since purchased the Maxx Alpha N in 06. There is a updated replacement NTK/NGK sensor. Basically there is a well known NTK/NGK sensor that factory honda's run most people use. Using the same setup on my motor now, but replaced the sensor once just for piece of mind and it was getting old.

                Should not see high/lean numbers unless going down hill or off throttle. When light coasting or the load changes to downhill you can get high numbers. Off throttle should eventually see air/cal(fuel cut). Under light loads though if there is a grade in the road and you truly see high ratios then adjust for adding fuel in that area. Most mid map areas depend on motor config to what it likes best, but I'd still stay at 14.7 or less ratio for cruising.

                  Do you have MAXX A/N or any other type of tunable system?

                    I just changed piston rings and installed the schricks and wanted to brake in the engine with stock intake. After that i will install the Carbon airbox and Maxx AlphaN and go to dyno for tuning. (couldn't do it before brake in period)

                      If your Maxx AN has full wide band loop control, you should have no problem breaking in with it installed. It's intimidating to change something all at once but the full loop control works and works well. It gives a chance to set, forget, and tune later.

                        I have the ALPHA-N+ ID V1.02 serial No.30 so i suppose it is an old one. Bought it used from a member here.
                        I think that the base maps are very rich. I am saying this because i installed AlphaN when engine was stock (with Carbon intake) and i saw the consumption go very high. I could also smell unburned fuel from the exhaust. I am not familiar with tuning and i better go to a professional to do it, last thing i want to see is my fresh engine braking (have done only 750kms)

                          You should get in touch with MAXX and ask them if they can supply a chip for your engine spec. With a stock chip, you are running the risk of bent over advanced. It may not knock audibly, but over advance will kill you big ends sooner rather than later.

                            True, that's why I mentioned if you have the newer version with loop. Yes that's older, and I'd break in like your doing first. Base maps do run rich. Also I'd ask MAXX about the full loop WB02 upgrade to your unit. Most all can be sent in and updated firmware with the new feature. It also is easier to tune with a pop up AFR box display on the screen, and best of all with the loop running it shows you plus or minus how many points you need to adjust for the field.

                              Thanks for the info, i will contact Maxx and see how it goes.
