"It's not happy under load!"
"Whatever. It ran!"
Hahaha. BANG!
Awesome stuff man. :)
You can get a 2020-2019 model megasquirt off eBay for around $200-$250 with built in map sensor and launch/anti-lag..... Hell a chipped Honda p28 or p72 ECU with a little modification would work all the same as well, certain chips have on the fly tuning capabilities just like a standalone ECU, best part is those ECS can be bought from junk yards for $20 and eBay for about $35, with the socket already soldered in and some random chip you can get them for around $100 $150 as well
Cheapest right now is over double that and recent sales cheapest is only $300-500. Buy one and send it to him! :D
I love the subtle tie in with the ZR1 style wheels paired with a mercury marine engine.....neat truck 😉👍
I love how you do everything on a budget. Not all of us could drop 2k like you said.
If he started a go fund me, or whatever, I'd donate $20 towards it.
@@actschp1 Yeah he needs a Patreon!
Yea! It shows that anyone can do the s stuff I’m doing without a ton of cash!
True...but a fully featured MS2 ECU is like $350.
So he still spends so much more then I or a lot of us could spend in years on it....
Well thats a unique swap.. i love stuff like this, and thats one massive 4 banger.
3 banger
@tunerimpala5658 are you high or just stupid?
It's been a while since I messed with a 730 ecm, but I am thinking that the injector strategy is different between a TBI and TPI. A TBI fires the injector every spark reference pulse and alternates from one injector to the other, but TPI fires all the injectors every 4th spark reference pulse so the injectors only fire once every crankshaft rotation. That would cause a really lean running condition. I don't know if that parameter can be adjusted in the program code or not. Another alternative might be swapping to a 16197427 pcm. It came in 94/95 GM trucks and will run 4/6/8 cylinder engines with TBI, port FI, or the funky Vortec spider injector system. There is a flag in the tuner to swap the injector strategy between the different injection systems.
Couldn't have said it better about tuning. Though I will say... I threw a 7747 with EBL in my vette when I did the engine work. I took a wild ass guess at the tune for the initial fire up and left it in open loop. It started and idled at 750 immediately... I let it warm up, pulled it off the jack stands and went on a 50 mile drive... AFR was around 13:1 the whole time. I was legitimately shocked it didn't stall or hesitate a single time. Fueling above 4k was rich but it drove well... Then I spent the last 3 years perfecting the tune and I'm still not quite there lol.
I know on Ford boxes, there is a setting that tells the ECU how many cylinders it has. I haven't tried doing this myself but I know it's possible.
It may be a setting on those as well.
The GM TPI ecu shouldn't care, the fuel injectors are batch fired and all fire simultaneously. All it needs to run is a couple sensors and the tune they were messing with.
singlehandedly lowering the property value with three whole 80s S10Tboxes. congrats man, you earned a subscriber
The Vette wheels look great on S10's.
I personally adore the very similar rims on the GMC Syclone. They are a little different than your wheels. They just look incredible IMO.
Hah! I like the "ghetto fab" 7730. But I didn't see it coming. Lots of Fiero guys use that ECM, for v6 AND v8 applications. Good show!
I was writing a whole big post with a bunch of suggestions, including some stuff about the tune, ways to test for a vacuum leak, and even about going to the thirdgen forum because they have such a strong group of GM ECM tuning experts over there.
I'm glad I watched this part before posting, lol.
Awesome that you got it this far. I've done some minor tweaking on a mid-80s GM ECM but nothing from scratch like this. I've collected parts to convert my car to that same 1227730 (it's a much better ECM than a few years earlier, and is a well understood favorite), but I haven't actually done it yet. Hopefully it won't be a nightmare - but there's a factory tune for the 7730 that's very similar to my car so that should make it a lot easier.
I think your tune is especially challenging because there's no factory tune for anything much like your engine, so you don't have a good starting point to work from.
A longass time ago I had a cammed 2.5L duke. Occasionally it would get into that low loping idle at stop lights, which was pretty awesome. It didn't do it very often though. I didn't know anything about tuning back then, probably could have made it run better if I had delved into that.
It's always awesome feeling to get a project moving under its own power. Congratulations now it's about the details of drivability
Hell yeah Bud! Good job, that thing is going to be a blast when you get the bugs ironed out.
Awesome!! I'm so happy for you. You put a lot of hard work into that truck. Can't wait to see you cruising on the highway!
Congrats man!! Been watching this back when you first started I think. Look forward to seeing it all done.
My boss (back in 2003) had a V8 Chevy Boat motor in his 1986 K5 Blazer.
Thing was awesome.
I definitely want to see that going good down the road.
Saw this truck on tik tok glad to see a RUclips channel keeping me motivated to work on my S15
never clicked a video so fast in my life
Hard work and perseverance finally paid off I'm happy for you!
Nice truck! Had a boat with the 3.7 4 banger. It was huge. Around 170HP but 260 ft lbs of torque in a small boat. It was quick and always thought how fun that motor would be in a small truck.
That’s cool. I love the old s10’s Chevy made some pretty good vehicles. When I get one I want to make it into a nice little race truck.
Love the tailgate dash. Love the whole concept! I just found your channel. Thanks for the content!
Just found your RUclips I like this stuff now I get to go back and see everything you have done
Saw this truck in a forum, awesome truck. Subscribed
Microsquirt is like 400$ and can be tuned with tuner studio which is free to download. Great DIY unit with lots on functionality. Also you can make the bay virtually wire free to the point where it doesn't look like it will run.
Runs like a boat always break down
Awesome making progress love to see it!! An your face when it backfired was priceless 🤣
Hilarious! I want an Nissan VQ in my S10. If my Maxima ever gets totalled, I might try it.
Get a megasquirt ecu, under 1k with harness and way more tunable
Congrats dude that’s a big moment! Stoked to see how far this truck has come along.
Love those Corvette wheels. Those are probably the best looking factory
Tunes take time 🤣 so much time! Keep goin brother just found your channel this is awesome. Thanks for sharing.
Be glad you have a supportive dad
Pretty cool I owned many Merc 3.0s and yes they were in chevs for many decades. But my ? Is why there a low revving 3800 rpm maxxed out motors. I imagine grenades in my head when the turbo spools if it will. Love the try tho. Friggin cul de sacs bad ass backfire. Keep at bro like the content.
Haha this one says it’s rated for 4800 max which is still lows as hell. I’ll probably let it spin to 5500-6000 and see how long it lasts. The old iron duke this truck had before held 18psi and that thing revved to 5500
Where did you get your speedometer from? That thing is so cool.
I like the tuning approach you have here. It's unorthodox for sure. It appears you have a *few* naysayers. I have gotten the same types of comments on the Frankenstein stuff I've put together.
That's freaking awesome! Still sounds like a 3 liter too..
Freakin sick dude! I gotta say, the Vette wheels are growing on me.
Love the build, but this is why i like my diesels lmao. If you have air and fuel they basically just run. Especially the mechanical ones
That’s awesome! Congratulations!! What an accomplishment! I’ve been here from the start to this is awesome
I like the S10s.
I like your truck.
I like the Salad Shooters on yours.
I like the marine motor.
I like the Channel!
Up, Up & Away man!
I have red an article a while back of a guy who put a SB2 head on a 3.0L. That's cool that you think outside the box.
I know I’m older but I really really like carburetors;
No wires!
AWESOME!!! 😎
SO HAPPY FOR YOU GUYS!
Dude this thing is wild. Good on you
Ostrich with map tracing, nice.
She's getting better and better
Microsquirt V3.0 $315 lol, but i like the do it yourself and learn as you go though. Too easy now days to just buy, assemble and ride so its cool to see the ones that dig in and do it like the 80s
Just found you on yt I love your s10 man I have a 88 s10 imma watch all the vids man from the first one to now love what your doing🔥
Awesome thank you! Try not to judge the first few too much, they kinda suck
now summer time, feels grate outside.
Yall live close af to each other
Hell yeah . Not bad man , can't wait to see it smoke some tires
I love s10 mini truckin is not dead..
that backfire though
Very cool, looking forward to seeing more
I didnt know you had a turbo and I always run my swaps on a separate wire harness from the vheicals. congratulations subscribed
maybe its how your exhaust is configured making it hard to find the sweet spot for mixture.
Or not.
❤️ the sawblades
There is cheap standalone options out there. Microsquirts are very reasonable at under $400 with an unterminated harness. Not saying you need it but if you ever want room to grow.
Bro i have watched you build this on tik tok from the start and I finally found it on here.lol
Never been this early! Love the build man!
Super fun build man, just ran across your channel. I hear you about people asking you to buy an EFI. Let's be honest, the build wouldn't be that interesting with a self learning system. Nice job man!
Doctor Frankenstein and his rat10 monster
Now there's a S10 dash that won't crack.
I’d get a haltech and start the wiring over . Your gonna chase issues with that setup until you spend a lot more then it’s worth
In the future when its more easily attainable you should definitely get a fuel tech ft550
Good job man👍keep on wrenching!
ITS ALIVE!!!!!
Didnt that company also help make the LT-5 engine for c4 zr1?? Looks cool AF man especially with the salad cutters👌
This will be your highest viewed tiktok when you post it
Hi AK, My name is Lou7807, I have a 1996 S10 extra cab I need a cab floor do you know where I can get one.
The piece I need is the section under the driver's seat{left side}. Floor is rusted out. Any help would be appreciated.
can you post a link to the 3rdgen page to explain the process for connecting the laptop to the ecm ? Awesome build for sure !
Super good job
I have a very similar digital dash like that in my 99 ford ranger and I can’t get the rpm to work so I’m just curious how you did that
Hell yeah! Good job!
wow i didnt think anyone was messing with these old ecms still. i gave up on my 7730 years ago.
There’s a couple of us weirdos around haha, they work alright for what they are!
Cool buiild! Always wanted to do the same with a mercruiser 3.7
My original 2.5 ideal was like 650 to 750 rpms
What wheel spacers are you running on the front of the truck
Congratulations brother
I watched the whole series on tik tok hehe
Niiiiioocccee.... Love the backfire
Will the corvette wheels just bolt up or do u need any spacers
Amazing stuff
I love the project and like you cannot wait till you get to log some miles on the shit box.
Is this the 3.0 cast iron boats and industrial application engine.
gotta love those seats i have one of the blue ultra ones in my sprinter corolla hehe
That’s sick! NRG made some sweet ass seats this year
You may have already answered this but why are you trying to use a boat engine specifically as opposed to some other 4 cylinder?
I reckon you need to keep those wheels i like the look
Wait.... didn’t you just throw a 400 sbc into this exact truck??? What happened with that?👀
So out of curiosity were are you located? Country is fine just how you said everything it sounds like the uk maybe....
Iv thought about a 3.7l merceuiser 460 4cyl in a ranger but didn't know how'd that go
Good build. I see in the background some tpi intake runners. Are they for sale, need a pair without any dents? Patience at the end will pay off.
What wheels are those off of on the rat 10. Is that the stock s10 bolt pattern.
That's awesome
From an antique computer to a not as old antique computer! There has to be millions of 4 cylinder later model cars in the junkyard you could source a computer from that was made in this century. 🙄LOL
Anyway, I know the newer v8 confusers are re-programable, maybe look for a 4 banger one that is easily re-programable? No need for a $2,000 confuser, a junkyard donor car should have what you need that you can splice onto your harness or totally yoink the matching harness off of that donor car too and use that. Grab the fuel system while you're there as well to upgrade to multipoint fuel injection. Use your Corvette injectors so they're big enough when you're ready for boost.
You're going to have a hard enough time tuning the throttle inj. without boost even worse when you introduce boost into the equation. Dealers choice though, I'll keep watching whatever you decide, just hate seeing you struggle with the antique operating system that has very little support and is very limited on its tunability. Good luck.
This is a Mercruiser 3 Liter... I would think it needs the computer from the boat. But they're so bound and determined to get it to run on antique hardware, that I really don't think he'll want to do it. We can suggest it until we're blue in the face.
We tuned this very setup with the older shitty computer to 18psi with no issue so it’ll be fine
@@ak_strem7010
So why the video with all the struggling then swapping out the older confuser because you couldn't get it to work without a turbo?
@@itseithergonnaworkoritaint7852 that's what I'm wondering
@@ak_strem7010 but that was an 8 cylinder with a turbo. You're trying to tune this computer with a 4 cylinder. I get that you don't have the cash to drop on an an aftermarket ECU, but don't you think that maybe the extremely limited computer is what's causing all of the tuning issues? That's why I think you guys are struggling to get things tuned correctly. If you had a more modern system from a more modern vehicle, then there's way more options to get it tuned properly. That's just my thoughts
How did you get the Corvette wheels to work.
Bad ass man
