Are you manual or auto?

I can't say for sure if anyone has done this before or not, I didn't come across any other threads on the matter. The idea just hit me one day while messing around with the UTEC. I'd love to be able to take credit for the idea but someone has to have come up with this before me.

I have no pictures as all you'd see is a few electrical connections and a relay.

well maybe you should make a few the sts guys would love this **** along with any other utec owner... im a hand on person so i would make my own but most people dont like messing with that so im sure you could get a good amount of people buying this from you

theres nothing really to make though.

he just wired in a relay between the 2 sides of the 101 pin wire. the relay is just grounded by the UTEC. when the settings are met in the UTEC, it grounds the relay trigger, which cuts the signal from the brake wire (same as flipping that manual switch).

that allows you to brake boost.

Its actually a pretty good idea. relays can do alot of stuff like that.

you do remember we drive g/zs lol most of the people who are boosted with these setups dont touch there own cars mechanically they drop it off and pay for it to be done... so something like what he made seems complicated to most

this is the relay right? so on the relay itself you connected power and 101 signal on the side that has three coils? no ground on the relay itself just the utec? and the side with the 1 coil you ran that to the utec correct?

Pin 85 +12v
Pin 86 UTEC
Pin 87 Wire 101
Pin 30 Wire 101

Standard BOSCH relay. Any autoparts store would sell it.

the way i would do it is to use the red wire (there shoulda been the black wire you grounded and an unused red wire) and use the UTEC spare solenoid settings to trigger the relay.

** don't be confused, that red wire is not a positive, but a negative trigger**

I use that red wire as the negative ground trigger for my methanol injection.
Basically you'd just set the parameter in the settings as like 1200 for rpm and 0 or everything else like coolant temp, etc.

for my setup, the red wire provides the ground for my pump relay so it turns on the pump when i hit a certain psi.

That way you are NOT restricted to map 5

ya but his instructions on putting 100 in the load columns doesnt make any sense, as thats not how I trigger that negative wire.

you'll figure it out though

well what number should be put in? wouldnt 100 be a constant signal? would that make the throttle close while under 1200rpms then making it struggle off the line at stop lights etc?

i dont even know what screen he was looking at.

you need to go to user constants

spare solenoid on: 1200
tps%: 0
air temp : 0
coolant:0
MAP(psi):-10
delay:0

that will flip the brake switch anytime you go over 1200 rpms, and every time the car is idling the switch is off, so you wont throw any codes.

only issue with this would be if you drive on the hwy. extended non-idle drive times will prolly throw the code.

in that case, i would set that rpm to like 7000 or something higher than your cruise rpm

wait so if its on wouldnt that ruin the purpose of having it? if its on its going to give signal to the ecu and i wont be able to brake boost
