With MS3, one already has 10X VE table resolution, so fudging for 200 max VE is not needed.

I agree that the "point" nomenclature is nearly always confusing. Does 2 points mean 2.0 or 0.2. Personally, I would prefer we say 2.0 or 0.2. But I'm like that. my

Questions: If one has a plugged spare O2 bung, upstream of the cat, that can be accessed from below the car, do dyno operators typically have a sensor that they can install there, and will they? Is that a question that should be asked of a shop before deciding whom to use?

Seriously. Once you go serial you never go back.

+1 on the Reverant serial-to-CAN conversion box. It puts an end to stupid ground errors.

but then you still need to assume the controller is reading the sensor correctly, and the sensor is outputting correctly.

youll just know for sure the readings from the controller are the exact readings it wanted you to see.


what really helps is if you actually calibrate TS correctly for an AEM gauge.

(Numbers added by me)

How will Item 3 overcome Items 1 and 2?

EDIT* Do you mean calibrate against a known better system at a dyno shop?

#1 and #2 happen to all.

Lc-2 or AEM, how do you know that the controller is telling you accurate results? You just to trust it's close unless you are able to compare it next to something else, which you also have to trust is accurate.

#3 is at least an ezpz way to get the controller and TS within .2 point of each other, not 2 full points.

AEM needs to be calibrated for 10-18.5 AFR and 0-4.25v. or in layman's terms: ~half the resolution of an innovate wideband*.

I don't believe the "aem uego" calibration in TS is setup to match the actual output, so you need to do it manually.





*the uego = 0.125v for every 1/4 point of AFR.
the innovate = 0.075v for every 1/4 point of AFR.

Doesn't that mean the uego has TWICE the resolution?

maybe? within the confounds of 10-18 in that configuration, sure.

but you can also program the innovate to output 10-18AFR @ 0-5v. where the innovate would be .075v for every 1/8 point of AFR.
