[@TheCarPassionChannel]

Did someone say ✨VVT Swap✨

[@NappMotorsports]

This is the way.

[@gayden4669]

The fact that this has 1.7k views is insane literally NOBODY ELSE ON KZbin has this insane amount of detailed research and information that your giving out for FREE

[@NappMotorsports]

Hey if it helps 1700 that’s great!

This guy deserves to get big on yt show some support

[@NappMotorsports]

Thanks man!

[@BuiltHalalRacing]

Congratulations on the new housing situation! Sounds like a dream regardless of the hectic times that come along with moving. Hoping all goes well for you!

[@NappMotorsports]

Thanks!

[@TomSL55AMG]

Great easy to follow tutorial. You rock!! Congratulations on the new house. I can’t wait to see what you develop in the new shop.

[@NappMotorsports]

Thanks man!

[@raym1763]

Your videos have pretty much cemented the idea of going with a VVT swap now. Content and quality is top notch as always. Out of curiosity (and a very thin looking wallet) do you have your own discount code with them or anything?

[@NappMotorsports]

I do not, sorry mate

[@trevorbreen6814]

what a great video to while while I do mind numbing work on my birthday. good stuff!

[@NappMotorsports]

Happy belated birthday!

Damn, never heard about this ECU, but it looks real nice. I'm running a Speeduino currently, definitely wasnt running 100% perfect until I installed an NB crank sensor. It'd be cool to compare all these new kind of ECU's. Seems like cheap ones are getting better and good ones are getting cheaper and I'm not sure when I want to push more than 300 hp in the future I'd trust the speeduino.

[@8145dwerdna]

@@BigBenlolz speedyefi (Speeduino) is what I was running before I switched to link as well. Had I known of this I probably would have gotten it instead of link, but I absolutely love links gui over tuner studio

[@NappMotorsports]

Would be a cool comparison but I’d want to have experience with them all first.

[@MReliet]

the "printer" cable is USB type A, the other end that we use for phone chargers is USB type B

[@NappMotorsports]

Thanks!

[@johnross8939]

That's a lot of info to digest. Will take watching the video multiple times for all of it to sink in. Saw your laptop is an ASUS ROG. What OS are you running? I have a G74sx with Linux Mint. You're getting me worked up about swapping in a 1.8L VVT into my NA6. We'll have to visit during MAG.

[@corifto1]

Do it! This car mayyyy be there.

[@NappMotorsports]

I just run Windows 11. I just have it for solidworks design, editing, and tuning.

[@Birb_of_Judge]

Well, you've convinced me to do a VVT swap. But im curious, what fo you think of Hummelink modifications VVT adapter harness and his products in general? His specialty is high HP naturally aspirated engines And in the topic of NA engines, what do you think of the skunk 2 manifold for that application (with a target of 180-200hp

[@NappMotorsports]

I haven’t used Hummelinks kit, but based on his other products it seems like a nice option.

[@seandevine4854]

Assume you want the ECU to match the Chassis? If I'm VVT swapping a 96 then use the BMM ECU for a 96?

[@ianp0817]

Yup!

[@NappMotorsports]

Yeah ECU should always match the chassis.

[@MartinMartinez-zq2yg]

I have a 93 with a 1.6 and i did a vvt swap with the 6 speed may i get the information for the ecm

[@NappMotorsports]

Beer Money Motorsports 90-95 ecu is the one you want.

[@adri1leusha]

Where would you recommend to install a flex fuel sensor? Before or after the fuel rail? Probably as close to the fuel rail as possible in any case...

[@NappMotorsports]

As close to the fuel rail as possible, but at the return side, not the feed

[@adri1leusha]

​@@NappMotorsports thank's for the (super quick) answer.

[@coknews4270]

So when I tell the coil packs to fire threw tunner studio they work fine but when I go to crank the car I have no spark any words of wisdom

[@NappMotorsports]

It’s not getting cam or crank signal then.

[@Birb_of_Judge]

Alright, just out of curiosity. Whats so bad about the Speeduino?

[@NappMotorsports]

I’ve seen too many of them fail to trust them

[@adri1leusha]

Any reason you chose the 90-95 ECU and not the 01-05? I assumed you would use ecu corresponding to the engine...

[@LoganDiehl2]

In most cases, you use the ECU that corresponds to the chassis/harness instead of the engine

[@NappMotorsports]

ECU needs to match the chassis

[@adri1leusha]

​@@NappMotorsports Ok, so this is (originaly) a 90hp 1.6 ! The weakest of the all haha!

[@jameshamlyn4172]

So what’s wrong with the speedyefi? I have one got form someone who ended up selling the car before he even installed it. So I got it cheap. The megasquirt is better if only because the afr is built in. They all run tuner studio. Is it a software or hard ware issue? Maybe I should do some more reading. I dont remember seeing any negative about the system.

[@8145dwerdna]

@@jameshamlyn4172 speedyefi does work. However it's still new so it's still a bit buggy firmware side. Even megasquirt was buggy in the early stages. I had issues with the dfco and a few other settings. Like how some of the injector voltage dead time settings would change when changing ignition dwell voltage and vice versa. What I mean is changing one of the axis on the table would change the other to the same.

[@jameshamlyn4172]

@@8145dwerdna Oh ok. I got it cheap so I’ll give it a go and see how I do. There’s no turbo or anything. This is more of a learning experience.

[@NappMotorsports]

Yeah it’s just a bit buggy. I’ve had 2 local guys have theirs fail and they get sent back for repairs. They do get fixed and work fine now, but they just aren’t my first pick.

[@jameshamlyn4172]

@@NappMotorsports ok thanks. It wasn’t mine either but $300 Canadian was half off with exchange and shipping. I was gonna do a mega squirt but that’s like $1200 or so by time it gets up here.

[@8145dwerdna]

What are these ECU based off of? A modified Speeduino?

[@alessandromeyer4888]

FOME-Tech formerly rusefi

[@8145dwerdna]

@@alessandromeyer4888 I've heard of rusefi. From what I read a bit back its a decent budget option and I also see it supports dbw which is cool. I just switched to link ECU though since I like the GUI of their software much better. It's cool they offer a pnp option for it now like Speeduino (what I had before switching to link)
