Default UTEC v. Link

I recently installed a full AVO exhaust, including the flex up-pipe and the AVO intercooler and BOV. I was getting ready to install the boost actuator and the Link intercept when I checked out the UTEC. It seems like I could get more out of the UTEC, including more reliable boost control. What do you guys think?

You CAN do more with the link... BUT the learning curve and ease of use is vastly different.

That's really the difference... since the UTEC can keep the stock computer around for simple housekeeping, it's a much "smoother" product to work with, especially for a first time user.

That is what I was thinking...the Link Intercept seems a little to confusing for me as newbie w/o access to a 4wheel dyno...

Had the UTEC for a week and I am verry impressed. Its definitely way to go unless you have unlimited time to tune the link.

Well after having the UNICHIP, then Link, and now UTEC. I'd have to say the UTEC has the potential to *do* more.

The abilities of the Link are restricted to the firmware version you get. I remember some i-clubbers having to return their entire board to get a new firmware update! I just updated my UTEC last night within 10min! Additional updates such as launch control, wb02 integration, etc. will be an easy update...

Sounds good...I will probably sell ym link then...would I need the AVO boost acuator with the UTEC or is the bosst controller in the UTEC enough?

Boost control in the UTEC would be good enough. I had to ditch the Link's boost control for a Blitz SBC-iD (not sure why........couldn't figure it out)...

What sorta boost problems were you having? I also had to ditch the Link's boost control for a blitz unit. As it appeared, I couldn't get anything above 13psi with the link...

Do both the utec and link use the factory solenoid for boost control? I never could quite understand how the design actually allowed for smooth and accurate control of boost pressure. By that I mean the T connector with solenoid on a dead end hose.
I got my sbc-id awhile back and absolutely love it.

The Link does use the factory solenoid for boost control. And since the UTEC is used inconjunction with the stock ECU, I'm assuming it does use the factory solenoid as well...

huh? what turbo where you using? Your the first I've ever heard of this problem

aftermarket is better anyway ...

as far as GUI ... link wins hands down of most of the ECU interfaces i've seen. Real easy to use.

just so much data being displayed ... its great

not the first I have heard of the wrx and boost solonoid. After a few installtion with VARIOUS piggys and ECM we have noticed a little trend growing with the WRX boosting whether its the solenoid, ecm, ecu, wastegate or what...we haven't figured it out. all we know is that some cars (no mods and just a boost guage)will boost up to 14psi and others (stock with just boost guage)will boost to only 13, 9 or 7. We have seen this happen on about 6 cars.
wierd...really wierd.


and for anyone who says the UTEC will do more than the LINK...hit the betty ford clinic and curb your crack habit.

I am using the PE1820. I figured it's a limitation of the factory boost solenoid. But it is a work in progress. I'm sure my tuners (i-speed) can figure this out...right Chris?

You will not get more out of the UTEC, I will say the UTEC is a good unit, but it has it's downfalls. The one major one is the fuel mapping. The fuel map is based on the stock OEM ECU fuel map. So as the stock ECU adjust fuel levels that will cause the car to either become to rich or to lean and cause problems. Very similiar to the unichip and the problems it has. Luckily you can tune it yourself every few days instead of bringing it to a shop to get tuned. That is a good thing as it will save you money. Or just do an ECU reset and be on your way.

As for the Link, you will not have to worry about those problems, as it replaces the OEM board completely. As for the learning curve take some time to get to know the software and you will pick it up pretty quickley. It seems most people want instant results, the UTEC does have that, but if you don't know what you are doing, thing can go boom. Same goes with the Link (things can go boom) and you don't need dyno tuning to tune your car, it is helpful for top end but that is about it. For us daily drivers we are rarely ever there, so tune the rest fo the car first. Get better gas milage, quicker response, etc...

I thought that UTEC had its own driver to run upgraded fuel systems as well such as running STI injectors....

I had UNICHIP but I was not aware of the fueling problem rather I've noticed the timing issue where stock ECU pulls the timing ridiculously to drag down the performance.

Also, Is it really true that the UTEC alters the signal to drive the STOCK injectors? I thought It had options to run it independently? I was under the impression that it had its own driver..........

Edit: I read the TURBOXS website. No UTEC does not have independent driver to run the injectors. It stated that it alters the MAF signal to adjust the fuel like UNICHIP.

OK OK OK... there is SOOOOO MUCH mis information here about the UTEC it's not even funny!

A: The UTEC has it's OWN (READ: ON BOARD) ignition AND injector drivers. It can take the ECU's request to fire an injector and IT (READ: the UTEC) will fire the injectors. The technology here also allows for you to run low impedance injectors. THE SOFTWARE IS NOT SWITCHED ON FOR THAT YET.

B: We have >ONE< programmer who is implementing features on a priority basis, and the injector and speed density software are not taking precedence to our current project of closed loop boost control, which is running great. From VF30/34's to 1820's, to VF22's... ALL OF US are having NO problem reaching boost levels of 18+ PSI, and HOLDING it. So.... if anyone doubts that... they need to check into the betty ford clinic...

C: You WILL have the ability to use true speed density (READ: MAP based tuning) which means..... that you can throw the MAF away if you want...

D: as for the UTEC doing more... the PROPER answer is that it has the POTENTIAL to do more with the open ended architechture it's based on. In other words.... it's all about software upgrades, which are free... But unlike Link... you will not see it until a dedicated group of testers (like me) blesses it. Not like Link's rep of buggy, and destructive software.

If you can't wait... buy a link... but if you want something supported on this side of the pond with better feedback to this community... stick around. If you wanna do professional competition, then you shouldn't be looking at EITHER system...

some of those are fair comments. I guess now we wait and see how good the upgrades and support truly are. Only time will tell.

Default Price & avalability?

All this sounds really good, I was about to get a unichip but now I like this much better. Any of you guys know how much this thing costs or where it can be bought? Thanks for any help.
