UTEC+Open loop boost control=Good times.
We got the open loop boost control working on the UTEC utilizing the APS Solenoid form their boost control. It was something we wanted to do for a while and just got around to doing it So now with the addition of an inexpensive Boost Control Solonoid, you can have the UTEC control a complete boost,timing and fuel map!!This eliminates the need for an expensive boost controler and gives you the simplicity of being able to store multiple maps in the UTEC and switch them on the fly...So for exmaple you will be able to store up to 5 different maps complete with boost settings, that you can switch between on the fly!!! Lets say you want to run one 9psi map for 93 octane on the street,now one at 9psi with less timing for the summer,or one for the winter oxigenated gasoline mix we get, or one for 13-15 psi for the race track..No problem!!
We will be doing some more road testing, but we were halted due to the weather..We did manage to mantain and hold 9psi using the UTEC open loop boost control feature.We were also able to produce a faste spool up playing with the Boost Control Gain feature in the user constants menu..We will be dyno tuning several maps this week and I will post the results.I just wanted to let everyone know, save your money on those fancy boost controlers

but you cant make adjustments to the boost on the fly, you still need some kind of controller for that, say you go to the track and want to play with the boost, or whatnot, unless you have a laptop hooked up, you have to stay with what ever boost the UTEC is set at, correct?

yeah but clearly thats the advantage of an EBC versus UTec boost control. However, the launch control and no-lift-to-shift features will only exist if you use the UTEC boost control so its a trade off in my view.

But if you have a Utec and you're at the track why not just hook up the laptop between runs? Or you could just switch to a map with more boost. Lets say that you have your everyday map(safe map) with x amount of boost. Then you could have another map that has x plus say 2psi for those race situations.

youre taking it the wrong way, like i said its great, but shouldnt replace a quality boost controller IMHO. its just easier to reach up with my finger and hit a button while driving, than working on a laptop. now for high hp cars on built motors running boost in the mid-teens, and flowing tons of fuel, i do see a place for it.
and yes, i agree with using a laptop between runs. but everyday situations, when you arent at track laptops are completely useless. say youre driving down the road, with a low boost setting, and a car pulls up beside you wanting to run, are you gonna say, "hold on while i pull my laptop out, or better yet lets pull over so i can do some adjustments".
nope!!

I don't understand why you would want to change your boost on the fly.

how much fuel and timing should be adjusted for say, 2 psi? what more can be done when youre injectors duty cycle is almost maxed out, and considerable timing is already being pulled, nothing.
once again, like i said earlier, this is a great accomplishment, i myself have been looking into buying the UTEC, but on a stock motor, running less than 10 psi, safely, with the UNICHIP, and having the ability with an EBC, to up the boost a few psi occasionally, another $1200 dollars can be spent elsewhere, like saving up for my new motor build !

Seriously, if your injector duty cycle is almost maxed out, you have no business turning up the boost..Im telling you, your just asking to blow your motor..
Now Im not trying to offend you, but I am trying to stress to you the importance of understanding what your doing and why your doing it..Then decide what the safest approach to achieve your goals.
Do not take offense,but what you are suggesting makes no sence and is pretty dangerous.
