How to quickly and EASILY tune a nitro rc engine in 30min!!!

Why not consider becoming a patron of mine? Help me, help you. :)

Hey guys!
Thanks for taking the time to get this far!
I've had this nitro for little over a month and wanted to learn how to easily tune a nitro engine from scratch.
So I defaulted my high speed needle and low speed needle flush with the housings and went at it.
I completed the full tune of this nitro engine in under 30min!! It's that easy. Sure it's not a race tune or one that will win me speed records, but it's good enough for the backyard basher or the leisure nitro owner.
Here are the steps to complete this procedure:
1. Check and adjust the idle gap to between 0.5mm and 1mm.
2. Change your high speed needle flush with the brass housing.
3. Change your low speed needle flush with the slide
4. Go out and run the vehicle. First tune the high speed needle and lean it out for the best top speed until it bogs. Then richen it a tad.
5. Lean out the low speed needle to get those crisp and snappy take offs.
And that is it! I hope this little procedure helps you to get a decent tune on your nitro engine to enjoy it!
Cheers!

I have watched every single tuning video on KZbin and now 2 years of my own tuning I see finally I see how to tune and wow what a adventure. 🤭 Your high speed needle went about 3 hours to lean and the idle gap and low needle needed to be shrunk smaller of a gap and maybe a bit leaner on the low end. Over all it runs and it’s fun that’s all that matters🤘😊

First video where I can hear the diffrence. Nicely done.

This video really helped me tune my rc man! Thank's a lot! I'm looking forward to more nitro rc videos man, I'm subscribing right away👍

Probably the best tuning video for bashers who restore cars I have ever seen #CorporateNitro

Great, easy to follow video.

My engine stops when igniter is removed?

[@MzanziRC]

I had the same issue. Changed the glow plug for a new one and sorted. 👍

[@cassianomartin2699]

PS: if the engine starts doing noise like ding-ding-ding-ding (pinging noise) when releasing throttle, it's too lean.

[@MzanziRC]

Thanks for the info. 👍

[@johnedwardroxas7939]

Which needle is lean? the lsn or hsn?

[@cassianomartin2699]

@@johnedwardroxas7939 usually HSN needle, its starving fuel in high revs. Also add a bit more, like a 1/8 turn to LSN. Mine is always HSN, can't lean it too much, it likes lots of fuel

@@cassianomartin2699 Thanks a lot👍

[@joshchatwin8569]

So clockwise to lean counter clockwise richen ?

[@MzanziRC]

Correct yes. Just think of turning in a screw into a hole. The deeper it goes in, the less space there is, so the less fuel can go through. The more you undo it, the more space and the more fuel.

[@mrxxlucaxx9715]

i have a very big problem because my car at this high settings just dies after tapping the throttle or gently applying it, any idea why this happens?

[@MzanziRC]

I suspect you are either running too lean or too rich on your high speed needle. Does the car idle good but dies when applying throttle? If so, reset your high speed needle to default for the engine. Start and idle the car and then start by leaning it out again and recheck if it dies when applying throttle. If it does, richen it a tad and recheck until you get to the sweet spot between applying hard throttle and gentle throttle. Good luck!

[@mrxxlucaxx9715]

@@MzanziRC see the problem is no matter what position the needle is after adding throttle it chokes and dies or stays, depends how fast i let go of the throttle

[@mrxxlucaxx9715]

i think its lsn needle fault but when its too rich car just goes insane and when too lean it dies

[@Rckid28]

This is one of the worst “tuning” videos I’ve ever seen, if you can even call that tuning… firstly set your idle than low speed (not high speed like said in the video) your car is not going to run at low throttle if that isn’t tuned first lol 😂

[@MzanziRC]

Thanks for watching guy! 😁

[@random_g-man9754]

Do you have to do this everytime you drive your nitro car?

[@MzanziRC]

No. But you could always just listen to the car and tune if it sounds off. If you get into more technical tuning, you even tune according to the weather.

[@cblack3470]

whats your opinion on the trx3.3 engine for tuning, feels like no matter what i do it over heats i end up running to rich to try and cool it down and then runs to rich/sluggish 🤔

[@MzanziRC]

I have no experience with Traxxas nitro's, but have read a lot on forums that the Traxxas engines like to run hotter than others. I believe the manual states 270F. Also depends on the air temp you are running in. Maybe try a colder plug and make sure there is good airflow to the engine. Good luck!

[@Rckid28]

Losi 2123 carb, traxxas carbs are trash

[@Rckid28]

@@MzanziRC you should not be giving advice, a cold plug does not mean the engine will run cooler

[@redblue40rc33]

Traxxas engines are not high dollar racing engines like a picco.....they're a budget engine with basic break in steps....racing engines take longer to break in and get tuned perfectly.....watch Adam Drakes breaking procedure on a new nitro...it helped my 3.3 a lot but it ain't race worthy just park or yard running...bout it

@@redblue40rc33 neither are the force engine in hpi models yet i had almost zero issues with them

[@New2Kendo]

You still have a 2 stage idle, by closing the idle gap you can fix that

[@MzanziRC]

Thanks for the info. Will look into it when I take it out again. :)
