Hello all,

I have Aquired an greddy profect B type-II electronic boost controller.

Now, I want this to read in psi, for those of you who have this exact controller, how in the hell did you get it to read in psi?

#2
I want to set boost at 15 psi, how would I go about doing so? and warning set at 18 psi

all I can find is percentage of high/low boost levels, and gain, what the hell is gain?

I have a Tt4e 5 trim on a 2.0 dohc.

all help is appriciated.

 

To tell you the truth, everything is in the instructions. You have to read it like 20 times before everything starts making sense. Do you have the instructions?

ugghh, I did, I stil cant figure it out.

It would help if someone has the same controler as me, to help me out. I spiked 26 psi today........................

 

you really need to do wat he said. everything is in the instructions. it takes a good while of reading it over and over and over again. then a light will pop up in your head. but to help you out a bit

1. to change into PSI unit:
a. At OFF mode, hold down SELECT button, and with in 2 sec. press the MODE button 2 times. Repeat this procedure to go back to previous setting.
*When PSI is displayed, it iwll show psi in x10 value. 14.5 psi will display 145, 10psi= 100 etc.

2. Boost setting is done by % so it means you'll have to mess with it then drive it to see wat boost you get till your happy. there is no way around that. Gain is an adjustment for the sensitivity of the valve control. so if your spiking alot then turn the gain down and if your boost is falling off top end try raising your gain. until you find a nice happy setting.

and well there are a lot of features with this BC. just keep reading until you understand

 

well that still aint helping him cause that's basically what the instructions tell you to do.

 

Then take it to a shop and have them set it up for you

OR

Read the manual again and again

OR

Keep fiddling with it and hope your engine doesn't blow

Good luck!

 

its pretty much self explanitory just need to keep reading or just sell it and buy a new boost controller

 

ok cool, thanx for u guys help!!

I got it now, I now have it reading psi well its psi x 10 so its reads 100. Right now i have boost set at 8psi (80) but it goes to 10, but stays, so i guess im happy.

 

what wg and spring are you using? and what are the settings on the boost contoller?

if your getting a consistant 10psi it sounds like you need to turn the SET down a bit.

 

im using a 5 psi spring in my Tial gate 38mm, dumped back into the downpipe of turbo. I DO have a big red spring I can put in, should I?

 

no thats fine. you can just let the ebc turn up the boost. what are your settings on the profec curently?

 

i think i have set boost low boost at 80 and 10% and high boost at 100 or something....

 

well there is a set, gain, and set gain. what are the setting for each??

 

set= 15% set gain = 80 gain 5% I hit 119 keeps spiking, I want an even 10 psi.....

 

seems no matter where I set it at, I keep spiking..........
im about to juts put in a bigger spring and unhook the damn thing

 

i mentioned this in your other thread too. the set gain is too high. keep it at 0 until you reach the correct boost level.
