I'm selling my old ms1 that was set up to use with an innovate lc1 but I'm selling it with a spare AEM wideband and would like to set it up for its new owner before it leaves my hands. I searched and this thread came up and it seemed to be similar questions being answered. But then again there seemed to be no concrete answer at the end.

Hate to drag up this old post but, I have an AEM 4110 series and having trouble calibrating. When I inputted Brainieack's numbers my idle afrs were off. I adjusted the high end to 17.2 and gauge and TS are right on. In boost, at almost any rpm, TS is reading about one full point leaner than the gauge. I'm assuming changing the 0v value would fix that. Being always apprehensive about running it lean, I like to know which direction I should start adjusting. Do I add or subtract? Or does the voltage need to be changed? This is new to me so bear with my noobnish on how this settings work. I just want to be able to run auto tune and have it work properly.

QUOTE=Braineack;1406448]make sure it you pick something from the dropdown it actually matches the published values of your controller.

most AEM gauges (like the 4110) use:
0v = 10AFR
4.25 = 18.5 AFR[/QUOTE]

I spent a bunch of time and took lots of logs, trying to get this wideband adjusted. I have it set now so it is close to Tuner Studio in boost ( +-.2) and right on in cruise and idle. The settings I used were.

Point 1 .2 volts 8.5 afr
Point 2 4.25 v 17.2 afr

My question now is do these numbers look reasonable?

I was wrong. I was only testing in third gear and maybe that's why. If you look at the log you see that I either hit or am close to my afr targets until around 5k rpm. There it starts to go rich, by as much as 1.5 points. Back to the drawing board. I'm thinking lowering point 1 afr a little and see what happens. Have to wait until I can get to a clear road. Maybe this weekend.

I have the same issue to joe morreale here. Any input on this? Also, does the y-intercept of this calibration matter or is the slope the only thing that matters in a linear calibration?

Hey ! I'm back in the game..... Trying to set up an AEM 30-300 to my son's MS 1 PnP.
I'm fairly sure that the above gauge is not a choice in TS
Is there another AEM gauge choice that will work ?

Also read that the brown wire needs to be grounded plus the gauge ground an the ECU ground is order for everything to read correctly.

Thanks.

Any update on that last post?
