Speeduino Launch Control Guide | How To Set Up Launch Control For Flames, 2-Step or Hard Launches!

Want to enable launch control or two step on your car with a Speeduino ECU? Here's how! This guide will show you how to enable launch control, as well as explain each setting and what it does. The process to setting up 2-step on a Speeduino ECU is very straight forward. You first enable launch control, retard your ignition timing and set a hard and soft limit. You will need to have an input for your clutch position for this to work. You also can set your ECU to a rolling rev limit which will be better for keeping your turbo spooled up. Note that launch control is hard on your car's engine and turbo, so keep this in mind. YOU are responsible for your own car and tuning, this video just shows you what these settings are capable of. My car is a Turbo'd 1993 Mazda MX-5 Miata running on a SpeedyEFI ECU.

Great video. To cut fuel only for Speeduino in tunerstudio, go to tuning->engine protection->common engine protection. Then select fuel only under protection cut

[@jacobk9049]

Thanks!!

[@BigBenlolz]

Ah yes love watching new miata vids back to back

Thank you for this very informative video.

You’re welcome!

I'm definitely trying launch control on my 97 1.8l. Rally inspired build with active aero and active suspension, with Borg Warner EFR 6258.

[@CashedOutCars]

Sounds like an awesome build to me. Do you have pictures and videos of it? I’m super interested

[@joemahadeo7317]

Very informing to know

[@CashedOutCars]

Glad this helped!

[@CashedOutCars]

Here's the much requested video on setting up Launch Control on a Speeduino or SpeedyEFI ECU. Enjoy!

[@albertocortes4596]

Greetings I am having problems with the ignition of my speedy you think you can help

[@e30victorino99]

Hey bro I have a problem maybe you can help me..I have a speeduino on my e30 sr20 but the problem is a have rpm spike it won't run smooth..

[@michaelmrdf48]

Hey man love the vids, quick question do you ground the switch or get it hooked up with 12V/5V? Couldn't get mine to detect it, super new to the whole speeduino ecu. Thanks in advance!

[@miralemnermina142]

I think it's the ground, look up in the wiki

[@amagedoncorelone]

Hi There, is there a way to setup launch control with a clutch switch that is grounded while depressed and open whil being pressed? I have a oe switch in my m52 Tur o e30 and would like to use it. It operates this way unfortunately.. Thank you in advance!

[@Beardchanics]

Again a very useful episode. Got the ECU now, just need to convert MK1 to manual then can setup. Do you know if an intercooler from a S3 could be re-used with a miata setup? Hoping to use spares part we have rather than buying new.

[@CashedOutCars]

If you can route it it’ll work! Just look to see where it’ll fit and where you can run the inlet and outlet

My project is a 1997 Honda Civic Coupe with a D16Y7 getting the "minime" VTEC swap that will be turbocharged along with much much more work.

[@CashedOutCars]

Awesome! Enjoy your build!

[@1801infarctus]

i just used your settings and got massive bang and flames 😂😂 so funny , thank you again for this and all your videos . but…is it bad for a NA engine? 😁 speeduino/1.8 mk1/decat

[@CashedOutCars]

You’re welcome! Hahaha you’re not doing yourself any favors by doing it.. I turned mine back off shortly after to prevent the temptation. Enjoy it!

[@DRIFTBAEEE]

Hey do you know how I could wire my launch control up to a switch? U would really love it so I could build boost when doing rolling launches

[@tannerjohnson1326]

Intercept the brown/white wire coming off the clutch switch. I did it yesterday but I cut it near the ms3 and wire it to a switch and back.

[@speedqbsushi3176]

Hey I was wondering did you wire your clutch switch into the ecu? If so how were you able to do it?

[@jacobk9049]

On the speedyefi ecu no wiring to the ecu is required. Just make sure your clutch switch is working. I had to replace the spring in mine

[@jacobk9049]

My launch control stays on whenever I’m driving without the clutch pressed, any tips?

[@BigBenlolz]

Btw if I get it right this isnt like Megasquirts clutch-switch based launch control right? Just so I can combine this knowledge with Gregs launch control vid. Sadly I cant get as much info on Speeduino even though I plan to get one next month and the diy-efi guys arent as helpful as speedyefi...

[@CashedOutCars]

It’s exactly like Megasquirt! This is clutch switched also. SpeedyEFI and Speeduino run the exact same firmware so if you have questions just post them in the SpeedyEFI group, they’re very responsive. Good luck!

[@BigBenlolz]

@@CashedOutCars I see thats nice then, thank you!

[@jacobk9049]

@@CashedOutCarsso do you have to wire the clutch switch to the ECU or jump anything internally? On my second turbo Miata project. Didn’t run launch control on the first one lol

[@GABEDEMAN]

Can I do this without a turbo? I got a Ka24e thats na on mega spuirt ecu

[@CashedOutCars]

Yes you will be able to!

[@raymaranciado5724]

Show how to set up boost cut! I have a bigger turbo than I bargained for and I want to set a safety of a boost cut, thanks!

[@CashedOutCars]

That’s a great idea, Right now I have mine set up too. This turbo tries to boost to the moon and I also want the extra safety. I’ll work on that video tonight!

[@CashedOutCars]

Just finished the video, it's live on my Patreon and I'll be posting it in the near future. Enjoy!

[@guspac88]

@@CashedOutCars that’s a fast turnaround 🏎

[@SorbonpesMC]

Hi, when i select rolling cut, it just doesn't limit the rpm enough. RPMs are still climbing.

[@trevorturkin9411]

Mine did this too. Asked Isaac and Chris on the forums and they didnt have anything to help. I just do full spark cut, but if you figured it out, I'd love to know how you did it.

[@SorbonpesMC]

@@trevorturkin9411 i just use full cut as well.

[@kevinalves1160]

I tried setting it up like this, and while it launches great, the limiter is still applied in gear. I checked the common clutch switch spring and it's fine, and I've disabled my neutral safety switch under the center console.

[@CashedOutCars]

That seems to be a common issue for people, I haven't figured out the solution yet. Is your car a running on a PNP Miata ECU? If you do figure it out, please let us know to help others out!

[@AlanGonzalez-om4rr]

@@CashedOutCars I've read in the forums what people do it's putting a switch to interrupt the wire going to the speeduino to avoid the limiter kicking in when changing gears.

[@NickVillecco]

Wondering if you ever figured this out? Mine does the same. Launch control is always on if I try to drive.

[@BigBenlolz]

Here after so many months, copied your settings, no pops or flames and rolling cut cant hold my RPM it just keeps creeping up, weird.

[@CashedOutCars]

That’s interesting, it worked fine for me but I haven’t used it since this video to avoid the temptation

[@woofernl]

Same for me, bmw m52b25, even if i set it to retard 35 degrees, no difference. It keeps it on the rpm but nothing else, also i have the registered version of ts, i do not see the option to add extra fuel with launch controll?

[@morganbsmall]

@@woofernl I just set mine up and at -30 it shoots crazy flames but my motor is a m52b28 also I’m using full cut limiter

[@yaaaserrr]

Wish they made this ecu for a 1.8 na :/

[@CashedOutCars]

They do for the 94-95! And they are currently testing one for OBDII cars, so it won’t be long until that’s available to the public! Also if you don’t need a PNP kit they made a fishdog kit that you can wire to run later cars

[@yaaaserrr]

@@CashedOutCars Best Channel ever. Sounds like I need to dig deeper and do some more research. Have got the 1996 1.8 NA. Thank you bud! Should totally make a discord.

[@CashedOutCars]

You’re welcome! Check out the SpeedyEFI page on Facebook and their troubleshooting and support group. A discord is a good idea, I’ll think about setting one up soon!

[@yaaaserrr]

@@CashedOutCars Just shot them an email. Looks like their in the works of the final 96-97 ecu. Thank you again!

[@matiganek]

What if you set you fuel adder to let's say -100%? wouldn't that effectively cut both spark and fuel? or it would just zero out the VE and cause your engine to die?

[@tinashetanyaradzwamabika2422]

Speeduino has that setting already to select which parameter to cut. Got to tuning->engine protection->common engine protection

[@matiganek]

Thank you for your comment :) i have already found out that myself. Also have been tuning my car by myself so now i got pretty good understanding of what is where and how to use it :)
