Im currently running a Greddy Profec B Spec II ebc and im having a number of problems with it. Im running about 60% or 20psi with gain set about 17. I've adjusted the gain each way, when it is between 15-20, I hit 20 psi and it immediately drops to 15psi, which means I can't get lower otherwise it will get worse. When the gain is around 20-30, it hits the set wastegate psi and gradually goes up, the response is so slow I might as well be N/A. Is this thing that fine tuning or is it possible the solenoid is dirty? I have the line running to the controller T'd off to my boost gauge, could that cause a slow response? Ive tried everything, any other suggestions?

Thanks for the help. An important aspect to note with your Profec B-spec II is that you have to 'wake up' the device before each use. This is not mentioned in the user manual and took me a long time on the phone with the people at Greddy to figure out. Ride Nowhere 20th Anniversary Rar. Every time the unit resets (I.E. Turning on your car) you must hit a button to 'wake up' the Profec.

I usually just switch from low to high and back again. In response to your problem: The 'set gain' setting controlls when the wastegate starts responding. Therefore, too low of a setting would cause the wastegate to open prematurely causing poor boost response, and too high will cause boost spikes. I found that in order to get maximum response with as little spike as possible. I had to dial in this setting to a couple of PSI before my peak.

(at 16 PSI I had it set at 13-14) I hope this helps. An important aspect to note with your Profec B-spec II is that you have to 'wake up' the device before each use.

Please note: This writeup was taken from an thread. It is NOT specific to SR20s but will help set you on the right path. Before you begin, you should have an idea of what you're aiming for. For EVOs, 19psi (131 kPa) seems to be a safe setting based on what people on the forums have found since it is close to what the stock boost pressure is, yet there is an increase in power due to the Greddy unit keeping the boost close to 19psi while the stock boost tapers off as the RPMs increase. I will henceforth refer to what you're aiming for as 'desired boost pressure'. Definitions and things you need to know before you start: SET This is how you set the boost pressure. Rather than setting it in psi or kPa, the Greddy unit allows you to adjust it as a percentage value, from 0% (greddy unit essentially turned off) to 100% (greddy unit will set the boost as high as it can).

This setup demands a certain amount of trial-and-error to properly configure it since you have to make adjustments, then drive under WOT (Wide Open Throttle) and see what the maximum boost pressure achieved was throughout the entire RPM range. SET SHOULD BE SET TO A CONSERVATIVE VALUE WHEN BEGINNING TO TUNE YOUR GREDDY UNIT. 30% SEEMS TO BE A CONSERVATIVE SETTING BASED ON MY TESTING AND BASED ON OTHER REPORTED NUMBERS FROM EVO OWNERS AND TAKING INTO CONSIDERATION THE LINK BETWEEN SET AND GAIN (see GAIN below). GAIN is defined in the manual as the value to adjust the 'boost consistency'. You don't really need to know exactly what that means.

Payroll Management System Project In Vb6.0. You should set GAIN to 0 when beginning, and you will then test the car under WOT while paying attention to the boost pressure. If the boost goes up and then falls off at higher RPM, you will want to increase the GAIN by a conservative amount (5% should be relatively conservative to begin with, then when you want to fine-tune it, you can go down to intervals of 1%). When you increase the GAIN value, the corresponding boost that you will go up to will be higher even if you leave the SET value alone. GAIN SHOULD BE SET TO 0 WHEN BEGINNING TO TUNE YOUR GREDDY UNIT.

START BOOST (also known as SET GAIN because that is what is displayed on the unit when adjusting this setting) is the lowest boost that the Greddy unit will begin increasing the boost from under WOT. You want this to be as close to the SET value as possible, since you want to keep as close to your desired boost as possible. However, setting it too close to the SET value will cause the boost to spike. You should set this to a conservative setting when beginning to tune your Greddy unit. Then you can fine-tune it later to get it as close to the SET value as possible without causing the boost to spike. Fortunately, you can set this in psi or kPa, thankfully Greddy didn't decide to let this be adjustable in% like the SET value.
