Here are the instructions:

EVC 4 Operation & Tuning Instructions

Functions:

Setting the volume knob: Whenever you make an adjustment the settings, you may see a flashing L, turn the knob down (counter clockwise), then it will show a flashing H, turn the knob up (clockwise). Turn it back and forth as instructed until it sets itself.

Mode: Allows you to change EVC settings. Hit once for Offset. (you must hold it down for a few second on the EVC silver)

2 times for Scramble boost, amount to add to the preset boost (i.e., 0.2bar).
3 times sets the length of time for the "added" scramble boost to last (0-30sec.)
4 times for Overboost Warning Mode. (***This is very important, if it hits higher than the overboost setting, the unit will shut down to stock boost. This will keep you from blowing up your car***) Always set this after you reset the EVC. Put it 0.1 to 0.15 higher than the high boost you are planning on running.

Alt: Switches between high and low boost mode. Lights up Green in Low, Red in High Mode.

Power: Duh!

Scramble Boost: Activates Added boost for the period you set with the mode button.

Resetting the EVC: With the power off, hold the top 2 buttons along with the lower right button to reset it. (Mode, ALT, and Scramble)


Tuning for Supra:

Turn the power on and reset the unit.

Turn the knob and set your stock boost.

(if you don't know it, set it at 0.65, hit the scramble button, and then go to redline in third gear. This is your Max stock boost. reset the EVC and then use this number)

Hit the scramble button and then add 0.15 bar to your stock boost (i.e., if your stock boost is 0.9 then enter 1.0) then hit scramble again.

Important: Hit mode 4 times to set your overboost.

Boost will now be set at you stock boost in low mode. Hit ALT to switch to High Boost mode and enter in how much boost you want.

Go do a 3rd gear pull and see if you get the desired boost. If it makes more boost than you want then reset the unit and add 0.5 more to your stock boost (0.2), if you get less, then add 0.5 less (0.1) etc.

If you can only get so close, you will have to use the Offset feature.

Hit the mode button once, and you will see 100. If you are overboosting, turn it up (between 101-150) if you are underboosting turn it down (between 99-50)

TTC Tuning:

Reset the EVC.

Hold down the ALT and Scramble Buttons (the 2 right buttons)
This will put the EVC in Learning Mode and display a L on the screen.

In third gear, accelerate until the EVC beeps and displays an H. (this may or may not be to redline.

Again in 3rd gear, from the same RPM as the first pull, go all the way to redline and let off. The unit should then beep and show your stock boost. Go ahead and set your overboost and then your desired boost level.

If you don't get desired boost (assuming its realistic), or it didn't go from L to H, you need to start from scratch.

If you still don't get the desired boost, you can use the offset button explained above to fine tune things.

If you can't get the unit to go from L to H, then you are either doing something wrong (i.e., not following instructions or are in Sequential mode). or you have some sort of vacuum or boost leak that is making boost inconsistent, keeping the EVC from learning your boost curve.

I take no responsibility for your actions, but as long as you set your overboost correctly you shouldn't be able to blow up anything. For the record all test pulls should be done on a closed racetrack.

Happy Boosting,

-Ryan Hawkins

Thanks RSA Supra! I had tried this instruction for the EVC4 Special edition already but the only time I can get my boost out is when I press the scramble button. Also mode+alt+scramble will not reset my unit. :(

To reset the EVC, turn off the unit, and then hold down the Mode, Alt, and Scb buttons. Once you do that, the unit should turn on and be reset.

Then to put it in learn mode, hold down the Alt and Scb. Once you this, it should show a Solid "L" on the screen (not a flashing one like when you need to calibrate the knob)

I was having problems...I set my boost manually to .8 bar and 1.00 for boost plus...with this setting, only 1.0 boost and was really slow.


Just did a learn mode....looks like it learned 60 for the stock boost! I'm guessing this since the low/high settings were at 60 and offset at 100 after this learn run. For comparison, after the manual set stock boost and boost plus methods, both the low/high settings were the same as what I had just set stock boost/plus too...leading me to believe that the learning mode set the stock boost to 60.


Now the car is boosting much better. Quicker spool-up.

I'll post full results later...didn't have much time with it yet but I can feel a difference!!
