[@Therendonfamilia]

Mine targets spot on using 1.5, 5, 0.4. with an 11.5 psi/sec rate limiter so that kinda changes things a bit. i got the rate from a log of targeting full boost and rolling into it. thats a stock L33 with a Z06 cam, 75mm BW and T6 1.32 AR hot side and single 66mm gate using a 4 port MAC at about 6800ft. lot of variables there lol but maybe it will help someone still :/ love the video as always!

Thx for the video Matt, the generosity you have with your knowledge really helps the common man. well done

[@Sleeperdude]

Great info thanks for sharing

[@hydrocarbon82]

FYI dual 3-ports can be plumbed to do this as well. In most cases people prefer duals since dual MAC 3-port flows less than a single 4-port, and that leads to more stable boost since it doesn't fill/vent the wastegate ports as fast. Another thing that can help stability is running a high-flow sintered filter (cone) or none at all. The small button filters can restrict airflow and cause an even wackier boost-vs-PWM curve.

[@soundslikealot]

Thank you, Matt!!! This one explained it all! But I would love to see/hear your thoughts about building boost while sitting on two pedals (have no trans brake). Their launch control I mean.

[@zero2583]

The same way just wire the trigger input to the proper brake pedal wire or a dash mounted momentary button like a trans brake. The ecu doesnt know you dont have a trans brake, it just knows you are commanding launch strategy.

[@nsboost]

Jess Neal if it was the cats Pajamas... you wouldn’t have to tap into a sensor wire that the ecu already has the signal from. Stupid.

[@nsboost]

Shouldn’t have to “tap” into any sensor wire. Huge oversight by Holley.

[@hooligans_garage7465]

Damn, watching your videos makes me wish I was smarter, I can’t get the boost control to work to save my life. I’ve watched your video 4 times and a21bravo’s video 6times still dosnt make sense lol. I’ll get it, I’m too dumb to quit.

[@dylanyz450f]

Quick question, im trying to run this set up with the 4 port. what are you doing with the output? Just running the boost solenoid into a PMW- like B3 or one of the outputs to trigger the mac to open and close. Thanks

[@kev90sc]

Great video Matt, thanks again for the knowledge!

[@callofgeorge]

have any input/info you can provide for dual mac valve setup, compressor source, using boost vs rpm for a street car? running a sniper on a 302, single turbo. mainly curious of pid settings ( i tested with shop air and dialed it in somewhat).. I'm guessing the pid values are affected by the psi of source pressure though.. but also curious of how exactly i should set the boost vs rpm table.. should it be flat to act as a stronger wastegate spring, or ramp it like the boost vs time tables.. block isn't strong, so i probably can't handle more than 8psi.. it has a 4psi spring in the gate.

[@andrewbakke4601]

I over shot my target of 6psi by 1.5-2 psi and is newer came back down to 6psi. I also noticed in the log that the boost controller would not go below 30%, even though the target was overshot.

[@joejoesmojo32]

So do you add a pressure transducer to the Dome or not? You said you didn't give it a 5 V or a ground, all you did was wire the signal from map to an imput configured like your 3 bar map sensor. I'm trying to understand your wiring methodology and getting confused.

[@LowBoostFilms]

1:57 I don’t have an option for pwm setup, is there a way to add that button?

[@BigJnWorldWide]

This is the kind of content that makes my brain happy. How do you go about figuring out the ins and outs of the software?

[@user-yr1dp7kr8g]

That’s a great way to control it. When you choose compressor vs co2 that is referencing the turbo compressor?

[@jasonblume2707]

Or just tell Holley to fix it, re program it so it works off manifold base boost control as it should to begin with!!!! but love the break down regardless, awesome content as always!!!

[@SloppyMechanics]

Trust me I have been telling them since I first saw the hardware

[@Tippmannballa]

I’ll bet it’s not a bug or error. They do this so it forces you to buy a holley HP. Matt always has work arounds lol nice vid

[@andrewwhalen25]

That’s incredible! Wow

[@RobbyVsGarage]

I'm trying this method out and I'm having some trouble figuring it out. seems like no matter what I target I get 18-19 psi. Is this a pwm setting I need to adjust or the PID?

[@Tobiwon999]

So do I use the 5 volts to power the transducer and the signal out to PCM for Dome control input?

[@or-ian6973]

I’m running dome map and I’m always 1.5-2psi off my commanded. Boost will spike then slowly come down to redline. Which having a falling boost curve is pretty annoying. I’m just starting to play with the PID settings. Do you think I need to mess with the sensor offset? Or what can I do? Only running 10lbs so the falling curve is not desirable.

[@or-ian6973]

Did dial my pids better but really the issue is hardware not software. At the time I was just using time but commanding the same boost for street use. Ended up going with rpm. I just command less initially to hit my desired not targeted than ramp it up from there to maintain.

[@95turbostang21]

Mat how would I go with installing Holleys high flow boost solenoid 557-201 using my turbo as the pressure I'm not using co2 or air compressor. The diagrams that you showed are for Holley older dual solenoid so now I'm just trying to figure out how to install they're newer style solenoid using the Dome pressure to Terminator X would I install it like method 1 because Holley newer solenoid has one in and one out port with two solenoids sitting on the top of their solenoid block

[@millsmotorvation]

You give great information. I have the Holley Max, turbo, 4L80e. I used a global tune that has your settings for boost. But I already have my boost leash running. EFI 3 bar MAP. How do I delete things in the boost settings and let my boost leash run boost with the 3 bar?

[@millsmotorvation]

Also what do I set boost settings in the Holley to run the 3bar and boost leash?

[@andymcdo]

So you tapped the map sensor 5v wire for the 5v input to fake out computer for the dome sensor?

[@SloppyMechanics]

Map signal to ecu, split into one of the Holley inputs, then told it that it was Dome input

[@buiItnotbought]

Damn i just installed a dome sensor on my wg because fueltech requires it for closed loop. I gave up an input for no reason then. It does seem weird that they dont use map for closed loop

[@michaellacombe9524]

for the PIN MAP do you assign Boost + Solenoid as PWM or normal output PWM with duty cylce?

[@TravisFabel]

I think I'm missing something here... If you're using the intake manifold absolute pressure as the feedback for the boost control, how does this handle closed throttle and part throttle? If I'm thinking about this correctly, when the throttle blade is not fully open the intake does not see full boost. Therefore it must hold the wastegate shut... And with a four-port that can be insanely high... Or am I just missing something and you're using a separate pressure sensor located in front of the throttle body?

[@ericmccarthy4060]

Hi Matt going to follow this set up but my question is can I go as low as 3psi on spring and have a max boost of 28-30 psi? Or would I need to have on board air to do this plan on racing a hard tire class so think i would need to leave on no or very little boost.

[@peanutspredicaments6038]

will using manifold pressure as dome pressure be a good setup for Dual 3-port solenoids (one as a vent, one as a fill)? im a newbie at this and using 2 solenoids because holley said that was the best setup for my single turbo

[@millsmotorvation]

Can you explain what to set the terminator at when you have a boost leash controller, or how to use the solenoid from boost leash with holley control.

[@justinp2993]

Can someone tell my in the outputs - configure - PWM setup, what the heck does the duty cycle table do with the wastegate setup the way Matt described here. That's the only part that still confuses me.

[@GoodSpeed150]

Thank you Matt. Another awesome video explaining the setup. Do you think holley will allow the map based control method in a future update?

[@LSXREVIVAL]

You are awesome !!! Thank you for this video. Can you take the signal from the GM map sensor also ? or can it only be the 100 psi (5V) Pressure transducer ? Also would my Mac 4 port solenoid work with the ramp setting with a 5 pound spring? I have a twin turbo dual tial wastegates and race port BOV. How do you connect the boost solenoid wires to the holley terminator x?

[@hermansmith1974]

Question? Have they changed where you can use map yet? And what about the Dominator can you use map on it or is dome as well?

nice video is there a way to send you my file everything on the car is perfect ,but my new deal is its on c02 with 8pound spring. on twin 76mm 5.3ls it love to leave on 12-15psi! im only getting 10psi and off the break it shoots to what ever i have the bottle at max 25 psi, bump works transbreak works,there are no other issues! basicly i want to try 12 then 14 on the break or bump something is not setup correct?

[@synna2010]

Thank you for making this video! I do have a question though.. I am having issues getting target boost on the trans brake.. the boost is completely controlled throughout the pull, however when trying to get up to 10psi on the brake it struggles.. and suggestions? also I am on holley HP not the Terminator

[@HaltomAutoworks]

So as of 9-25-22 holley still hasn't given us a "Target Map" as an option on terminator X? I believe I have the latest update, I guess it's just another reason for them to justify the higher price for the dominator ecu.

[@Onhaey]

Matt so you physically spliced the 5v map signal from the Holley harness? I’ve got it all set up in the software. Just want to make sure before I cut my harness

[@zero2583]

Yup

[@816murphy]

I am confused as to why on your data log it is targeting 24psi when your table is only setup to 19psi. Did you use the boost scramble button on the dyno to target the 24psi target the dyno?

[@TheyCallMeKRock]

I know I’m late to this party but I had a question after watching this. Could I move the pressure sensor that’s in my waist gate to a vacuum block I have mounted on my firewall instead of slicing into the MAP 5v sensor wire? Thanks for all you do.

Did you primarily switch to Holley from MS?

on this car, i went about 6 inches out of the wiring harness, and crimped the map and input together, and then set it up, i cant recommend this for most people anymore as MOST struggle to make it work correctly.
