Confusing electrical problem

[g-via]

I currently have:

Greddy Profec B Spec II
Greddy Full Auto Turbo Timer
AEM UEGO Wideband


I had originally had my set up with power for my turbo timer, boost controller, and wideband off of the ignition.

The turbo timer kept counting up, and the wideband was giving slightly off readings.

So I rewired the wideband to the cigarette lighter because I thought the heater core in the sensor was too large of a load on the circuit. But still the problem persists.

So...

I'm confused to why my wideband would affect my turbo timer?

Did you ground your turbo timer? If so, is it a good ground? Just a thought.

agreed.
make sure they have seperate good grounds.

OK so weird now.

I checked the grounds, all good.

So what is happening now:
Turn the car into ACC, the turbo timer starts counting UP
Turn the car ON, the turbo timer counts DOWN, back to the starting point

Also (when driving) the timer used to start counting up around 2300 rpm in LO mode, and 1500 in HI mode.
Now it starts counting up at 1850 rpm in LO mode (haven't checked out HI yet).

Strange? I have yet to read about a similar problem involving their Greddy Full Auto Turbo Timer.
