Calling Unichip Users

[low_psi]

Well, I think the boost contoller in the unichip just sucks. There's a reason it's only a $50 EBC. Get a profec-b spec II and problem solved. You can run it along with the unichip just fine.

meh, i'm hoping I don't spike over 13psi once I get my UC in. we shall see.

Where did you get that price from? The 'EBC' is built into the unit, it's not an add on box like a GReddy (or whoever). The only 'additional' part is the solenoid. Those range from $20-$120 in the aftermarket world.

But I have heard of a number of people running the GReddy Profec with the Unichip have do not have the high spiking issues. I think the GReddy is just a more advanced design that's made to keep boost level where you set it.

I'm very interested in trying one of these:

I got the price from when people were asking jack about a discount if they ordered it without the boost controller, and he said that would only make it a $50 difference.

So that's just the solenoid they are taking out (the blue and black piece)... All the boost control would still be there, just not used.

I guess it's probably because the other EBCs can adjust the gain... how fast it can build boost. Unichip said that they could tune out the spike, but then the throttle response would suffer.

i just put in my UC and boost controller and on high boost, i'm holding 12psi... anyone care to help me out? no boost/vacuum leaks etc. maybe wastegate line is too long? i could shorten it by 4-5"... kinda stumped right now.

what other mods?

 

[low_psi]

fmic, 3" downpipe to 60mm JIC, stock intake w/ k&n... think that's it power wise lol

 

[goku4658]

u nervous?

 

[nvmsp]

" Could you just use a upgraded wastegate with a stiffer spring and then have the unichip retuned without the spike?"


any answer on this question? about the stiffr sprimg w/o re-tuning.

 

[low_psi]

u nervous?

yes. 10psi is the max I want to run up top. I'm gonna call UC Monday and see if they'll send me another boost soleniod to test.

High boost will be run tonight w/ homebrew racegas and then no more until I figure out the problem.

What is the problem...? It just stays at 12?

 

[Yay-Boost]

What kind of boost gauge are you reading the 12 psi on?

 

[nvmsp]

I think other members have already replaced the wastegate spring, I believe Blkzoomzoom has and MPNick has done it to one or 2 of the vehciles he has worked on.


DOES he do it so the wastegate is lined up the way it should be to just bolt right back up ?

yep, no spike, just holds 12-13psi. its read via an autometer gauge, which is accurate by ~.5psi. even if the gauge was reading off, i'd still have a spike.

any help is much appreciated. gonna call UC after lunch about testing another soleniod...

That accurate based on what they say? Or you've actually verified this specific gauge is accurate?

 

[low_psi]

Nah, accurate as to stock boost, boost after mods, boost w/o soleniod on; all in respect to my car. I read ~5-6psi on stock boost, which is gonna be less than the actual psi if the gauge is reading incorrectly(most ppl run 7-8psi w/ similar mods). So for the gauge to be reading more at a higher psi doesn't make sense.

Regardless, I should have a spike despite what psi I'm actually running so something isn't right. I get a spike w/ the soleniod off, I should get one with the soleniod on aswell.

My unichip is for sale. 640 bucks plus other stuff.

Not that I have $640 right now, but what other stuff are you talking about?

I have a parting out thread called msp parting out.
