Anyone with AEM UEGO and Auto Turbo Timer, HELP!

[g-via]

Hi zilvians

I know I am definetly NOT the first person to have an UEGO with a turbo timer, I need help with this problem please!

The UEGO Sensor has a small current pull that triggers the Auto Turbo Timer (Greddy) to start counting.

Below is how I have them both set up

white w/red stripes = power always
blue = ACC
black w/white stripes = ON

I have changed the power wire for the UEGO to different sources, it doesn't seem to matter.

Anyone who has an auto turbo timer and uego that works, please chime in!

anything

THANKS

did you use the harness neccesary for a turbo timer? or did you splice it in?

[g-via]

i spliced into the appropriate wires

i am surprised that no one has ever had this problem. either i am the first person to have a greddy turbo timer and uego, or no one wants to say anything

You could add a relay to your UEGO ignition. The relay would be triggered by the ignition, so not a lot of current draw...

I never add any problems running uego with turbo timer(apexi) though...

im the same as frank... running a uego with an apexi timer. no problems

the current draw is from the sensor itself, not the power from the ignition.

are your turbo timers the auto countup style? or just a preset turbo timer

Where do you think the sensor get his current?!? pretty sure it's from the ignition!

They are count down style, we can adjust the count down time.

Alright

Can you explain why the relay solution would work?

Also, but auto countup style, I meant that countdown time "builds" based on rpm on high and low settings.

[army240]

It should work because the relay takes less curent than the UEGO sensor. But anyway, it should work like it's connected.

So if I understand the problem, as soon as you start the car, the turbo timer is counting down?

The power for the UEGO and TT are wired to ON on the ignition

When both units turn on, the TT starts counting UP, like I was driving the car above 2K RPM. This happens when the car is not running and also while it is running.

I found the problem to disappear when I unplugged the sensor harness for the UEGO gauge, but left the power and ground harness in. I read thru the UEGO manual and read:
"UEGO sensors use a 'current pump' to determine the actual oxygen concentration within the sensing element. The output is in the form of a very small current, which varies depending on the air-fuel ratio."

I believe this current pump (via the sensor harness) is interrupting/confusing the greddy's auto count-up feature. By me installing a relay in the ignition power source, wouldn't that screw up the 'current pump' from the sensor??

[army240]

Ok, I'm not really familliar with "count up feature above 2K", I personally don't use that. But putting a relay will not affect the operation of the UEGO sensor, if it's well connected.

If you need a wiring diagram for your relay, I will make one. Just let me know!

greddy TT has two settings : High and Low
the TT starts building time at different RPM levels

anyways, here is how it's wired up

Even if I did install a relay, it's basically a switch.

Once the relay tripped, the current pump from the sensor would still be there and force the TT to start counting up.

What's happening with your trouble, is that the ignition circuit is overloaded. If you take off the UEGO of the equation, it's working fine right? So it's because the UEGO is taking too much current. If you install a relay(which takes almost no current), it will stop the overloading problem.

A relay is a small current controlling a bigger current... you connect the "86" post of the relay to your ignition wire, the 85 to the ground. This is the control circuit. Then you connect the "30" post to an alternate power source. For you, it would be the battery, via an inline fuse. Then, you connect your red wire of your UEGO to the "87" post of the relay.

No more trouble for you.

I have a weird issues with my greddy tt too. I have a uego also. My uego is powered by my cigarette lighter and I don't have a problem like yours. But my tt acts normal when my blower motor is on high. And when it's off the tt counts up A LOT faster. And with the blower motor on it will make it start slowly countig down and acts normal. It's weird
