APEXI FULL AUTO TIMER FOR TURBO & NA
Hey there guys after alot of time reasearching how to install turbo timers etc, i could not come up with and DIY instructions for an Apexi Full Auto timer for N/A & Turbo, i have had the timer sitting on my garage wall of parts for a while and since there was no DIY instructions anywhere for this timer on R33 i was affaid to install it. Anyhow 2 months later, i have decided to just go for it.
So, this is a tutorial for how to install a Apexi full Auto timer for N/A & Turbo.
------------------------------------------------------------------------------------------
The Apex Auto Timer allows the vehicle to idle for a preset amount of time after the ignition key has been removed. In turbocharged vehicles this prevents hot oil in the engine from coking up in the lines. Hard driving can raise engine oil temperatures to dangerously high levels. Proper cool down is essential for a healthy turbo and engine.
The Auto Timer stands as a technological marvel. The pen shaped, compact size makes the Auto Timer one of the smallest turbo timers on the market. This allows a clean and stylish installation virtually anywhere inside the car. The unique multi angle joystick button allows easy navigation through the many feature menus.
Upgraded in every way from the previous model, the new Auto Timer can automatically determine the necessary amount of after idling time. A Manual Mode allows the user to preset desired idling times from 0 sec.~10 minutes in 16 increments. By inputting O2 sensor voltage, the Timer can also display theoretical air fuel ratio. Since the Auto Timer uses the factory O2 sensor which is primarily designed for emissions, the readings may not be as accurate as racing air/fuel ratio monitors. The Timer can also display critical data such as O2 sensor voltage and Battery Voltage. To prevent potential theft while running, the handbrake safety feature shuts off the vehicle when the handbrake is released without the ignition key.
CONCEPT:
Provide turbos wind-down time
CHARACTERISTICS:
Easy to use; Simple and attractive design

!!!Caution/Achtung/Attenzione!!!
Follow this guide at your own risk. You have been warned. We are not responsible for any actions you take. The information contained here is a guide and should be acted upon with consultation from your local tuner. If you are unsure or are not confident don't do it.
Items you will need include:
- The Controll unit
- Relay Unit
- Specific wiring harness
- Double-Sided sticky tape
- Splices, binders, soldering iron, electrical tape (either of these)
- Vehicle Specific Chart
- Instruction Manual
- Flat head screw driver
- Phillips head screw driver
- Scissors
- Zip ties
- socket set (or spanner 10mm)
ON relay -
black wire = ECU ground
white wire = ECU o2 sensor
grey wire = Hand brake switch
step one
Disconnect the negative terminal off the battery (battery located in boot). [use 10mm socket or spanner] - make sure wire is kept away from terminal.
step two
Undo the bolts underneath the steering collumn [use phillips head screw driver] - think there is six bolts.
step three
Once the screws are all out keep them somewhere safe (a jar?) now gently pull apart the plastic peices surronding the steering collumn. Once these are off there should be easy access to the key clynder.
step four
Pull the harness coming from the key cylinder. (in come vehicles the whole key cylinder is a harness)
step five
Now insert the specific wiring harness. (now after many days or trying to find one, i did some research & found out that HKS specific wiring harnesses are compatible) insert the harness between the key cylinder.
step six
Connnect the three prong timer harness to the relay
step seven
Now you should have the specific wiring harness install with it connected to the ignition & into the relay of the turbo timer (this should not interfer with any alarm systems etc as i have one and it did not)
step eight
Use a zip tie to, connect the harness somewhere under the steering collumn area out of the way, and so it is not visible when pannel is replaced.
step nine
Feed the black and white wire behind the centre console and into the feet area of the passanger side.
step ten
Remove kick pannel on passanger side to reveal the ECU (this is in r33 not sure in other models)
step eleven
Splice the black wire from the relay into the Engine ECU ground wire [please refer to the vehicle specific ECU diagram]
" When not using the O2 sensor, A/F ratio monitor and automatic after idling functions, connect the ground wire to the chassis."
step twelve
Splice the white wire from the relay (O2 sensor signal) into the O2 sensor wire from the ECU [please refer to the vehicle specific ECU ]diagram]
step thirteen
Remove gear surround, gear knob, gear boot, to reveal 2x bolts that hold down the centre console, undo these [using phillips head screw driver] and the 2x bolts in the compartment in the centre console with the lid (they are @ the very bottom)
step forteen
Remove the center console completly to reveal the hand brake, so you can the the wire, the grey wire from the relay gets attached to the hand brake switch here.
- so from the relay you have the black wire to the engine ECU ground
- the white wire from the relay to the O2 sensor wire from the ECU
- the grey wire from the relay to the hand brake switch wire.
Now before you go any further reconnect the negative battery terminal [using 10mm socket or spanner] and turn the igniton on to make sure that: 1. the timer lights up and is functional, 2. everything on the dash is working lights etc 3. the car starts.
step fifteen
tidy up all the wiring using electrical tape to keep them secure and non visible, i lined mine under the carpet (for the ground and 02 wires) and through the centre console for the hand brake wire)
Conclusion
Once all is completed and functional, put back the centre console, gear surround, gear knob, gear boot, kick pannel (over the ECU), steering collumn surround and drivers side ignition pannel.
Hope this tutorial has helped people install the Apexi full auto timer for N/A & turbo as well as many other timers.
