recall screen values never change

Hello, I am using a SMG and everything is working very well, however the values for the afr, ret, mv on the recall screen never change

when I pull data logs it just says 10.0 afr target which is exactly what the gauge shows statically, whether idling or driving

Is this because I am using a aem wideband separately? if so how do I data log the afr through the SMG? ret never changes either... even when the check engine flashes under WOT

using SMG via bluetooth and ALDL droid

switch 2,4 on

Sounds like the wideband is not properly connected to the ECU to read AFR. The analog ouput from the AEM needs to connect to the previously unused pin F14 at the ECU.

On the recall, there is a minimum time you have to be at WOT to show the peak readings. As I recall, I think its something like 1 second over 50% TPS.

It likely won't run very well with switch 4 on, and the wideband not connected.

It seems to run quite well with switch 4 on, I just drove it WOT and it went to 11.5 as I have my parameter 7 set to

I will double check that I have the analog wire in the correct pinout location, could it be a ground issue?

At WOT with switch 4 ON, if my analog wire wasn't connected what would it run like? I will take it out again to verify that it goes to 11.5 once I check the pin

Analog out on the aem is normally white.
Right ok, I tried blue just to see if anything would change and nothing. Put the white back in.

Now that I've run it a few times I see that the afr stays in the 10.0-10.8 range although set to 11.5

Idle goes lean and erratic

So clearly I'm not getting a reading form WB to the ecm

If the WB and SMG are grounded to the same bolt would that affect anything?

I will have to triple check again that I am using the correct pin location as well...

Will you be stocking velosyty chips again soon?

I know there is at least one guy up here looking for one from you
