What model is your AEM gauge?
RedCelicaTRD":2fxvs1s5 said:In his previous post he mentions that he is using an AEM Wideband gauge. The AEM gauge has a narrowband (0-1V) output to go back to the stock ECU along with the Wideband output that in this scenario would be unused. But since we should aways double check here is how I assume it is hooked up:
(WB Sensor)----(AEM Gauge)----(Stock ECU)

The narrowband output is a cyclic 0-1V output where the ECU determines the amount of time that wave signal is above 0.5V vs. below. If the time is equal, the engine is runing at 14.7 air:fuel. Does that AEM gauge provide a wave signal with that 0-1V output, with about 1 or slighly more cylces per second?
My mistake. Should had said EvilStig. I've corrected that error now in my previous post. Thanks for finding my error.RedCelicaTRD":3j3d69vz said:I think things are getting a bit confusing in here. I don’t have the (vehicle) issue. I’m going to hold off on commenting until EvilStig gets a chance to do some testing.
In all of EvilStig's posts, I was trying to get to know the model/part number of his AEM wideband controller, but so far, we don't have that information yet. Maybe AEM doesn't have model/part numbers on their controllers? When I looked up information on AEM, I also saw that none of them had a simulated narrow band 0-1VDC output for narrow band ECU's, but that is what AEM is selling today, not necessarily what EvilStig may have (he may have an older model that, at the time, was made with that simulated narrow band 0-1VDC output for older ECU fueling control). Was just trying to get all the information that we could to try to provide some help.RedCelicaTRD":2df72tlo said:I stand corrected! The AEM wideband does not provide a 0-1v output. Other brands like PLX do, but AEM does not.
