ok well the install was pretty easy but tuning this damm thing is a joke not to mention it was raining when i was doing test runs so after 2 hrs of dicking with the tuning and rain i called it quits i read up on this boost controller for hours last night and read up on settings today turns out this controller isnt very user friendly its not hard to figure out how to operate but seems to be very inconsistent ive dumped a couple thousand in the fd in the last 2 weeks and im starting to think it was mostly a waste of money and time im going to try some more tuning tomorrow Ive put in the last 2 weeks greddy smic,elbow piping pettit unlimited ecu greddy profec b spec 2 fluidine radiator performance plug wires m2 intake rx7 store hard pipes ordered on june 4th and STILL NOT IN pettit resonated midpipe pettit dp peter ferrel catback [already on the car] i swear the car was fasted before i did al this stuff It really makes me sick when i think about it maybe tomorrow it will all come together

whell the first time i was messing with the EBC i tho wow this is hard.. once i started it was easy... fourth gear down somewhere make sure you wont danger others or yourself and adjust from there.. .. i would recommend getting it tuned... they usually adjust the boost and all.. always remeber rx7s are money pits so you might thing its a waste.... yea rx7 store has the things you need but they do take forever to ship

Here is a great write-up from a guy I know from Tampa on the PRofec B Spec II:

First order of business, throw away the instructions - they are off, something got lost in the translation.

there is actually two ways you can set boost on this unit.

In the boost display (unit defaults to this) mode, turning the dial on the right will up the duty cycle of the boost solenoid. Press in on the dial to set it to memory. On my stock T25, I set it to 35% for .9 kpa.

hitting mode will bring up gain function. Increasing this number will increase boost, but it's real function is to control the sensativity of the solenoid. I left mine set at 10%. Turn the dial one way or the other, then press IN on the **** to commit the setting to memory. If you have issues with the boost controller not holding boost consistantly, turn the gain up, otherwise, leave it down.

Pressing mode again will bring up "set gain", which is the start boost feature. Set this number fairly close to the target boost, again by turning the dial and pressing in. On the stock T25, I got my best results by setting it .10 kpa below my target boost, but you can play with it abit. The goal here is to hold it as close to target boost as possible, without spiking past your target boost. For .9 kpa, I set mine to .8 kpa.

The next function (the display should turn red) is the overboost limit setting. This number represents your upper threshold of boost - a number you do not wish to exceed. This is handy, as setting this function up correctly eliminates you having to adjust your boost based on weather conditions. If boost reaches this level, it will give you an audible beep, and the display will turn red. You should set this slightly above your target boost, I set mine about .07 kpa above my target boost. Again, set it using the dial, pressing in to commit it to memory.

Pressing mode again will get you to the overboost reduction setting (display will remain red). This setting determines how much duty cycle of the boost solenoid to reduce when over boost happens. I set mine to -4% using the dial. If you set this number too high, you will have excessive boost fluctuations. Too low and it may not bring the boost down far enough.

The next function is highest boost recorded. You can reset this by pressing the dial in and holding til it beeps.

Pressing mode one last time will bring you to turn on or off the last boost display. Turning this on (by turning the dial) will display the last highest boost you achieved every time you go back into vaccum. Pretty handy, especially when setting boost levels.

Let me know if you are have questions.

thats why i stick to the 3 ***** on my ebc, i hate the spec 2 because of the to much setting things on that one.. and to me if u have the ebc out were you can see it.. it does get annoying with that blue light. whell to me at least

mine i set at ...38%
gain left at 10%
set gain is at 15%

seems to stay right around 10psi...
i still need to get back out to play with it some more ...havn't had the time...every time i go out ...the damn troopers are all over the highway..
