I have been using an Apexi AVC-R (blue screen) for about a year now and cannot fault the unit.

That said the scramble function allows you to set a boost level and an interval for that setting. I have never used this function and want to know if it is possible to set up so that as long as the scramble button is depressed the EBC will give the higher boost setting. (being so it activates whilst a button is depressed... not for say 6 seconds fter the button has been depressed)

I would rather not have to change EBCs, but i want to be able to run around a circuit at 10-12psi and when i hit the straight bump up boost to around 18-19psi.

Having to preset the scramble feature for a set interval means i can only use the scramble on say the main straight.

Thoughts???

I have the HKS EVC4 and its really easy to set up like that, but the AVC-R - sorry I can't help you. Maybe try to get some decent product documentation from somewhere. Apex's manuals are ordinary. The guy I bought my EVC form was lucky enough to source the proper tuning/install manual from a HKS tuner direct. Aparently, the manual that comes with the EVC is 3 pages, but the one I have is 28 pages, very detailed.

The people doing the work on my car (Bel Performance in Homebush 9763 7022) have hooked up a scramble button on the steering wheel for the AVC-R.

It should be cheap as it's just a momentary button.

I'm not sure I want one of those as I'd be tempted to "HIT IT" at every traffic light :)

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
