I just picked up a Greddy EBC for a good price. it didn't come with instrutions so i got them from here http://www.greddy.com/img/PHP/products/pdf/682.pdf .there are a few things that I'm still confused about.
first is about the GAIN. here in this how to guide http://www.sr20forum.com/turbo....html it says to set GAIN to 0% when beginning. but i can only get mine to go down to 5% it wont go any lower.
Next is about the LIMITER. in my manual it says it can be adjusted between 0-99% and in the HOW TO GUIDE: it says it should be set to your set value minus 4%. My set value is 30% minus 4% = 26% but the highest i can adjust the limiter is 20%.
is this normal, am i reading it wrong or is this thing defective?

never mind i came across some good info while searching google that answered all my questions. i'll post it if anyone is interested in it.

Here is a basic chart type setup to aid in figuring things out(I personally chose to use PSI instead of KPa.)
CONTROL—MEASUREMENT—“EFFECT”—(DETAILS):
Set -- % -- “Desired boost psi”(Use to set general boost level)
Gain -- % -- “Boost consistency”(Use to minimize boost taper—proportionately affects the overall boost level)
Set Gain -- psi -- “Boost response”(Controls when the wastegate starts to open–use to maximize turbo spool up)
Warning -- psi -- “Maximum boost level”(Sets the maximum boost that you do not want to exceed)
Limiter -- % -- “Maximum boost modifier”(Sets the amount to reduce the boost psi if warning level has been reached)
Peak Boost -- psi -- "Highest boost achieved"
TUNING PROCESS:
Initial setup: (I was looking for 22 psi)
Set 30% (this should put you at roughly 12-15 psi of boost)Gain 5 % (this is the lowest setting available)Set Gain 18 psi (desired amount minus around 4 psi)Warning 23 psi (I was already running 23 psi w/ ECU control)Limiter 1% (there’s really no reason to do more than this—the car can easily handle 23 psi with a stock turbo)
1. Turn off the unit to set it to PSI, then turn the unit back on and turn PEAK BOOST to "on". 2. Set the WARNING to one above desired boost, and the LIMITER to 1% (or whatever you want). 3. Start to increase the GAIN first to minimize or remove the taper. In most cases you will not be able to completely eliminate the taper. Increase gain in small increments until boost is held pretty much to redline. If boost spike/surge occurs – go back down in value until it subsides (at this point you’re done with the GAIN). 4. Adjust for the SET value next—simply by adjusting the percentage until you reach your desired boost levels. In my case that was 22 psi. 5. Set the SET GAIN value last—the reason for this is because you want to get it as close to the SET value as possible to maximize spool up. Once you hit a boost spike or surge—lower it down till it subsides.
All done!
