Apex’i ITC Installation
DISCLAIMER: I AM NOT RESPONSIBLE FOR YOU SCREWING UP YOUR CAR.
Concept:
Ignition Timing controller that allows
the user to modify ignition timing from inside the vehicle.
Characteristics:
Simple 5-knob face, precise timing control
Comments:
The Super ITC allows the user to modify the crank angle signal and adjust the
ignition timing of the vehicle. Ignition Timing can be modified + / 15%. By
using the Super ITC in conjunction with the Super AFC fuel controller, a new
level of performance and flexibility can be attained which was never before
possible with entry-level sub computers.
The ITC allows the user to modify ignition timing according to RPM specific
levels, much like the Super AFC modifies fuel. The five knobs on the face of the
unit indicate a particular RPM level at which timing may be modified.
installation:
This is a very precise installation. If YOU screw this up don’t whine about your blown motor to me. Follow these directions very carefully and if you don’t have a lot of experience in this then pay someone else to do it! YOU are at your own risk. Modifying the timing on any car can really screw it up.
If you need pictures to help you find your ECU then check out the Greddy BCC installation. Just remember that you are not installing the BCC you are just looking at the pictures on how to get to the ECU.
Here is what you will need:
ITC wiring harness and head unit
10mm socket
Wire crimpers
Butt connectors or you can use the supplied bullet connectors
Lets get started!
OK, Now you have all of the wiring done up. I really want to stress to every one that this needs to be a high quality installation. This isn’t like installing a BCC this can really mess up your car.
Reconnect the wiring harness to your ECU. Make sure all of those wires are tight.
Next make sure that on the back of the ITC head unit that the Car select dial is set at 0 and All of the dip switches should be UP.
Plug the harness into the ITC. Reconnect your battery cable. Leave everything at 0 and hopefully start your car.
As far as tuning goes I recommend you leave everything at 0 until you are on the dyno with an experienced tuner, Air/Fuel monitoring, etc. You will want to retard the timing in the high end under boosting conditions. But that is all I will give. Do NOT email me and ask me what I set mine at because my car isn’t anything like yours :P
I don’t know how much HP this mod will make if any. It will help reduce head pressure and could even solve some high end detonation problems most Supra’s have. This would be especially helpful if you have a single turbo.
