Electronic Boost Control: Wiring, Settings, and Results [Speeduino and Megasquirt]

In this video I show you how to wire in an electronic boost controller into a car with a standalone ECU, specifically a Speeduino, SpeedyEFI, or a Megasquirt. I go through how to wire in your boost control valve, how to set it up in tuner studio, as well as the differences between Open and Closed loop boost control, and I show some data logs to analyze the results.

You're becoming the real Speeduino ambassador here, its such a pain to find all this info for this ECU. I'm looking forward to more of these.

Fyi, the newer speedyefi board have the boost pin already wired out to the evap solenoid plug in the engine bay. They started doing that around 2021 so you might not need to solder anything.

just pulled my new one apart boost pin is still open would still have to wire it like the video i guess only wondering what pin to select in tunerstudio

Man this is awesome information. That said what do you mean by T’ed off and goes to the header pin 2x on the V1.3 boards? Which is the one I have and wish to do this. Also if you have a link to some information for all of this that would be greatly appreciated and helpful. Thanks bud I’ve learned a ton from you over the past year

@duske00 2 жыл бұрын

@CashedOutCars You want to keep boost control low below 3500 RPM, this is because you dont want to get more then your lowest amount of PSI in this low rpm range. This wont promote spool, just create a higher psi limit. High boost on low rpms causes rods to bend, the map below 3000 should be 0. (Unless the wastegate spring is like 4psi, wich is very low)

@CashedOutCars 2 жыл бұрын

On my car it did help spool, since higher boost down low = more exhaust flow at lower rpm = faster spool. This is because your boost controller is holding the wastegate completely shut vs allowing it to slowly open slightly as boost builds. (They open gradually, not like an on off switch). It had no effect on the upper PSI limit since that is controlled with the boost control table at higher RPM, since this turbo still spools relatively slow, so I never make lots of boost in that area

NICE VIDEO AGAIN MA BROTHER. BTW THEY SAY WHEN YOU USING A SPEEDUINO YOU MUST REMOVE A TOOTH ON THE CRANK SHAFT TRIGGER WHEEL. DID YOU HAVE TO DO THAT?

@agerrgerra1361 2 жыл бұрын

He's got a 1.6 Miata that didn't come with a toothed crank trigger wheel, only a cam angle sensor on the back of the intake cam. Speeduino supports the "99-05" trigger pattern used on the NBs with VVT, which is used to compare the crank angle to the cam angle to measure the cam advance on VVT cars. I don't know if the 96/97 trigger wheels are exactly the same, but they're not necessary since you can just rely on the cam angle sensor, though the crank angle sensor does provide extra resolution for more accurate timing. Apparently Mazda just needed the crank trigger wheel on the 96-97 USDM cars for misfire detection to pass OBD2 requirements.

Hi, I might be dumb or my english is not the best, but where did you set the actual targeted boost level? In boost control menu there wasn't any place for a pressure input, and you said the boost cut is a different story - it's just for hard limiting and protecting the engine. In the table where you set the numbers to 100s and 10s weren't pressure inputs either, for the open loop. Then how do you know what is going to be your max boost? Do you have to calculate that in head related to the duty cycles values? Im lost

@CashedOutCars 2 жыл бұрын

It’s a bit trial and error in open loop! There isn’t an easy way to calculate what your boost level will be based on duty cycle since there are too many factors. Closed loop will target a boost level based on your target table. Good luck!

@hungarianMX5 2 жыл бұрын

@@CashedOutCars Another thing just popped into my mind - did you change the internal wastegate spring to a smaller psi rating? In my theory: if you set boost controller to eg. 7 psi but the spring is rated at 9 psi, then it still going to reach 9 psi of boost because the spring won't let the actuator move at a lower pressure. Or you simply already went above the stock spring rate with boost :D ? Sorry for this much question, but you are working on these mods and you are the best source of valid information because of this. I appreciate your content and help.

@CashedOutCars 2 жыл бұрын

You’re correct with what you said! The lowest boost you’ll be able to run (assuming no boost creep) is what your wastegate pressure is with no boost controller. You can raise your boost with one, but you can’t lower it!

@ThomasGallinari 2 жыл бұрын

Is it worth buying a standalone ECU with no other power mod?

@LoganDiehl2 2 жыл бұрын

Price to performance, not worth it. BUT it gets you going in the right direction. You'll learn how it works and you're setup to install power mods

@CashedOutCars 2 жыл бұрын

It depends, like Logan said, it’s a good first step. Also, with a good tune you could pick up some moderate power gains, more so on 1.6 cars since you can get rid of the AFM. The key is a good tune
