ahahah i had my start boost at .8 instead of 8.0.....oops(but this didnt seem to help my spool...)

and how come your guys set is so high and gain is so low????

id have to check my car but my set is like 17 and my gain is 35......

That is probably your biggest problem. Lower the GAIN and up the SET but remember that SET and START BOOST need to be close.

 

how do i get the set close if ones a % and the other is lbs.

 

I explained that ^^^

20 psi max on your setup means if you want 10 psi here are your settings:

SET: 50%
GAIN: 10% (play with it)
START BOOST/SET GAIN: 80 (account for profec misreading boost by 2 psi)

 

to find the boost limit or what the system is capable of. is that done by what the turbo can handle or what the current wastegate spring can handle.

so if i have a 5.5 spring. some say it can handle 11psi, some say whatever i want it to handle.

thanks

if you have a 5.5 psi spring then the max you can boost is found out by this:

5.5 psi x 2 = 11psi take half of that which is 5.5 and add it to 11 psi which = 16.5 psi.

so the max you can boost is 16.5 psi that is your wastegate springs limit for full boost.

so on this greddy profec b the first setting is changed just by turning the ****. the range is from 0-100 percent. this can be interpreted as a percent of yout max boost which is 16.5 psi ok? so say you want to boost 10 psi for example.... you need to calculate what percent of 16.5 = 10 psi. so if 0 % = 0 psi then that means 100 % = 16.5 psi right? so if you want to boost 10 psi then you need to find out what percent of 16.5 psi = 10 psi......

so we discover that 61 % of 16.5 psi = 10.065 psi thats close enough.

set your SET boost ( turn the ****) to 61%
leave the gain @ 10 for now (play with that later to help if it spikes)
now the 3rd setting SETBOOST (setting right after GAIN) this is read in PSI. so if is displays 103 you can interpret that as 10.3 psi ok? and you want this setting set as close to your very first setting of 61 % which is also known as 10 psi.

so since your first setting is @ 61% AKA 10 PSI then you would probably want to have your 3rd setting SETBOOST set @ 90 or AKA 9.0 psi.


hope that helps and remember that this is for a wastegate spring of 5.5 psi

if yo have a different size wastegate spring find out the MAX limit by using the procedure mentioned first above in my post and then figure out everything else accordingly

 

cool, just making sure

but why dont you just say, wastegate spring x 3.


platinum

 

[sarcasm]cuz then it might confuze people lol[/sarcasm]

 

ok so if i wanted to run the stock setting of 5.5

i should use 34%

cause 34% of 16.5 = 5.61 ( close enough ), i know i can leave it at 0 and that will do it too. but basicly anything below 34% will have no effect on the system . correct ?

platinum.

 

yea but thats too complicated lol.

all you have to do is turn the thing off and you will run stock wastegate spring boost. voila

 

well this this is not hard then. makes sense to me now.

so i should have no problem getting 1bar out of a 5.5 psi spring.

thanks for your help

platinum.

 

Well, I just read this forum like 3 times. Let's see if I got it.

I'm using a 1 bar spring in my wastegate. Yes "1 bar" (14.5) . So my wastegate limit is 14.5 x 2 = 29 + 1/2 of that = 43.5 psi (3bar).

I want to boost 18 psi which on the profec in psi is 180 or 1.24 in bar. So my first setting would be 41.37% (41%) because 18 psi is 41% of 43.5 psi.

set gain should be set 10% good starting point. Increase or decrease depending on whether it spikes, and how it holds.

Set gain should be 180 or 1.24 bar.

How did I do???

that sounds right. but the SETGAIN setting you shoudl try setting it at 2 psi lower than what you want as your psi...

so since you want to boost 18 psi you have your first setting at:
41%
then your gain at:
10
then your set gain at:
160 or 16.0 psi as it shold be read.

start with that. this wil have your wastegate open up a little early so you dont over boost. having it set at the same exact psi level as your target boost level which ia 18 psi will sometimes cause you to over boost and spike...


hope that helps

 

well that did not work

i just tried it out.

boost = 34 % (16.5 x 34% = 5.61psi )

gain = 10

set gain = 35 or 3.5 psi

car rocketed to ~10psi and i let of the gas. so what did i do wrong.

im thinking this. 0% = stock boost. 5.5psi

so really the 0 - 100% setting is only playing with 11psi.

so i did 34% which 34% x 11 is 3.74, add that to 5.5 = 9.24. and that's about what really hit.

does that make any sense

It sounds like your wastegate spring is 5.5 psi. You can't go below the wastegate spring. Set the set gain at 55 (5.5 psi) or maybe 60 (6.0 psi) to see if it holds. I know what you read earlier probably confused you because people are saying to go 2 psi lower then desired, but I just thought of something. Your boosting very little so go ahead and set the set gain to 55 or 60 and let us know how it goes.

yeah I thought about setting it 2 psi lower after I posted... I think that the accuracy in boost depends on where you have your vacumm lines for your boost controller, and boost gauge. Mine reads pretty accurate, but I know that if there too close I will experience over boost or spike. I'll let you know how it goes...

 

well with a set gain lower it should not make me boost higher, just sluggish or slow spool up..

i can try that though, but being tunned for a smaller turbo ( basicly untuned ). 10psi is started to get scary

i will tell you though, 10psi pulled hard as sh*t. i cant wait for this weekend when i can finally be fast again

platinum.

 

are you sure you have your vac lines correctly connected to your boost solonoid? i had that same problem and no matter how i set it i always over boosted..

make sure if you have external wastegate that your COM port is connected to TOP PORT OF WASTEGATE and that the NC port is TEEd inbetween the side port of the wastegate and your pressure souce.

if you have a internal wastegate i cant helpyou there lol

but if you haveeverything hooked up exacly liek you are supposed to then the directions i gave you are perfect.

Just try what I suggested... I read somewhere that the first two settings can effect boost. You can't leave the set gain at 0.

 

do your guys's spec 2's ever reset?

 

i have the side port of the wastegate and the NC port on the controller hooked to manifold, each with it's own line.

i have the COM port hooked to the top of the wastegate.

the NO port still has plug in it.

That sounds correct...

When I was at Trackmasters last week. Myles from Revhard was there, and he called someone to ask them about the ports not in use and whether they should be plugged or not. He un-plugged the NO port, and it held boost with no problems. So I don't think that's an issue...

thats close but hook it up like this. i have it this way with no problems:

COM port to top port on wastegate
run a vac line from your compressor of your turbo to the side of your wastegate now ok.......
now take a vac line and run it from the NC port and TEE it in with the vac line going from your compressor to the side port of your wastegate.

take the plug out of the NO port on your solonoid there should be nothing in there.

try it that wasy withmy settings and come back and post results

 

and no HELLA my spec 2 doesnt reset i have never heard of that. sorry bro
