@@BlaserBuilds when setting up boost vs time do I need to setup a trigger? Or if I set it up how you did just flat across will it always control boost to that desired number? For now I’m just adding a few lbs on top of the gate and don’t need to ramp it in. Just hold that pressure at all times. Thanks
@@BlaserBuilds Got it all setup. I see now when set flat it’s just a constant control. Mine is about 1.5psi off. If I command 8 I get 6.5 settled pressure. It’ll spike about .5 but comes down quick
I set my car.up just like you said in this video and ut worked great for one pass it added boost like it should. On my 2nd pass it didnt add any boost. Any ideas?
I get an initial spike should I play with p or d? Or should I try and ramp it in with time? I command 5dome and get 8 spike then correct to 5-6. Dome map 3port like 4 port 6 psi spring.
a21bravo check out Aaron Mello write up on the sloppy mechanics private Facebook page. Mostly about the filter circuit. That will help with the PID tuning Edit: if you haven’t considered it and you are input limited I like some of the hybrid open/closed loop options better. You can do target boost but don’t have to deal with all the PID tuning to get it to work and don’t even have to use an input for DomeMAP
I'm using domemap as well and have it setup through boost by gear with a 4port Mac valve using raw duty cycle target boost/rpm. Working great for me. Can lower it for the street for each gear and then all the way up for at the track. If you have any interest would be happy to show you my tune.
@@jakekw900 wish I could just send a picture....so looking at the face of Mac valve, and electrical wires on top, the bottom left side goes to side port of Wastegate. Top left goes to top port of Wastegate. Bottom right goes to turbo compressor nipple, and top right is open to atmosphere
@@BlaserBuilds yep I have that correct I have dome/map set up as 5 volt input going to the 5 volt wire on map sensor with white/black a-13 Output on boost output to b10 pwm- gray black going to one side of Mac valve Other side of Mac valve going to 12v ignition Set up as boost vs time requesting 15psi and only getting waste gate which is 10. Am I missing something ? I’ve watched the video on UA-cam many times but still can’t figure out how to make it work Turbo reference running to both bottoms of waste gate running to port 1 on Mac valve and port 2 running to top of wastegates
@@BlaserBuilds no I don’t. That’s what I’ve been thinking as well. But I didn’t know if you had a button etc. what way could I do it without having a button etc
@@BlaserBuilds hey I had a question where do you run iat to the Holley harness? And also my oil pressure sensor is a different pin connector how do I connect the oil pressure sensor
So if I have this right you tried the closed loop map and dome control deal but decided to go with boost vs speed instead....or did you still need to tap that map signal wire to do boost by speed? Sorry just trying to wrap my brain around it all. I also wondered if tapping that map signal wire drains the signal at all...I don’t see how it would but I just wondered about my own crank signal I split on my own setup to keep the factory stuff in play for my dash etc.
It doesn't effect the signal since it is a voltage signal. If it was a thermistor like a temp gauge it wouldn't work because its resistance based. Boost vs. Speed still uses the dome function to target. I dont have an in input release set up (trans brake), so speed vs time will work better for me. I could tie it in to my rev limiter input if I wanted to use boost vs. Time.
I’d like to see a long 3rd gear roll on with boost set to a steady 10 or 15 psi. I’ve tried multiple strategies with map as dome and could never get a level boost level. Always overshot and would fluctuate 2-3 psi continuously. Never seen anyone get it working correctly yet.
17:24 in my new video... The scaling is off so the lines are at different spots, but 3rd gear start about 1lb over then near dead nuts at 16lbs at the end. But you can see the blue line level off, and yellow solenoid duty bringing it towards target.
Good info.
Thanks!
This helps. I’ll just tap the wire at the ecu though. Only need to run the IO wire to the ecu then.
That works 💪 I knew this was temporary so I didn't want to mess with the harness.

Will I need to use solid state relays when using pwm- to control Mac valves
I got the same ?
I set my car.up just like you said in this video and ut worked great for one pass it added boost like it should. On my 2nd pass it didnt add any boost. Any ideas?
Hmm what's the input? Speed? Did it lose the input?
@@BlaserBuildsI found it was my cheap amazon Mac valve. Thanks for your vids they were alot of help.
This is the best video explaining the domeMAP. Thank you for this.
From, a beginner to this (lol)

Thanks forvthe video its very easy to understand. im curious when you do boost controll this way. What triggers the boost ramp to start?
So what if you have the 5 bar map sensor from holley? Do you still select 3 bar for ur input?
Are you running the signal wire that’s meant for a dome pressure sensor to the map sensor?
Basically, just steals the 5v from the map and using it like a dome sensor.
...looking forward to seeing some results on this one!
I gotta do some reading on the PID control and learn that... I wouldn't even know what to adjust right now, lol.

@@trialbyturbo9106 I've seen a couple others. Wanted to try this.
a21bravo I run it with dial a boost. Gives me 11 different “closed loop” boost by mph options. It’s pretty great

How did you plump the 4 poet valve to make it work?

I haven't tested my setup yet. Just got it wired in. I did it the same way. What activates the boost controller?
That looked terrifying 😬
I’ve been working on this for 2 days and can’t figure out how to make it work. How did you wire the Mac valve
One wire to a positive, other wire to Holley. It will be a ground output.
@@BlaserBuilds yep I have that correct
I have dome/map set up as 5 volt input going to the 5 volt wire on map sensor with white/black a-13
Output on boost output to b10 pwm- gray black going to one side of Mac valve
Other side of Mac valve going to 12v ignition
Set up as boost vs time requesting 15psi and only getting waste gate which is 10. Am I missing something ? I’ve watched the video on UA-cam many times but still can’t figure out how to make it work
Turbo reference running to both bottoms of waste gate running to port 1 on Mac valve and port 2 running to top of wastegates
@@johnbarnett8629 The issue might be with boost vs time. Do you have an input trigger that starts the time? Like trans brake release or 2step release?
@@BlaserBuilds no I don’t. That’s what I’ve been thinking as well. But I didn’t know if you had a button etc. what way could I do it without having a button etc
@@BlaserBuilds what if I do boost vs speed and just run it desired that I want from 0-300mph will that activate Mac valve ?
Does the terminater x have scramble option?
Yes you can set up scramble.
@@BlaserBuilds would you happen to know if you can turn bump into scramble
@@turbovicsatx2910 yes you can.
@@BlaserBuilds perfect can’t wait to get mine it’s on the way

a21bravo cool thanks for the info man. Good to know.

a21bravo just watched video. Looks like it does hold pretty steady. 👍
hi
I never could get mine to not overshoot and wag at high boost levels. Good luck
3:53 time to change underwear
👍
