Can I do this to my '99 TJ, 2.5 with OBD2?

Man, you're channel is going to BLOW UP! Don't change a thing. You're awesome 👍

Went from a 4.0 to a 2.5, came across your vids, read the comments where Jeff introduced himself, found this video, now I need to learn more! Was gonna swap to a V8 but now I might hold off...

I'm looking forward to follow up videos of this!!

Been waiting on this video

Good points 👍 Subaru has a 300 hp 2.5 motor

My old v rod with exhaust an powercomander made 107 rwhp .. I’m Deff going to look into this for the 94 2.5

I look forward to the progress, you got my attention. All I’ve been doing is researching what swap I want to put in my yj. I don’t need a ton of power I just want to cruise at 75 on the hwy and all these little HP booster you share I do.

Holy f****** s*** dude! how have I not seen this video? I've been rebuilding my 2.5 l Jeep for a couple of years now.... Well it would have been sooner thanks to covid. But I'm rounding the corner of the hardest part the engine the drivetrain and now the last part is the body. But I definitely needed something to remedy my little 2.5L engine. Thanks for the video! 👍👍👍👍👍👍

Very interesting. Looking forward to more videos on this. Are you going to run the stock injectors or the 4 hole upgrades? Or BOTH!?

Looking forward to the next videos! I’ve owned several four cylinder Tj and YJ over the years, my current is a 95 YJ 2.5 manual, 4.0 tb, spacer, header, no cat, flow master super 10, electric fan, crt ignition @45k voltage, accell u groove plugs, Harland sharp roller rockers, four hole injectors, on 32/11.50/15 I live in East Tennessee lots of hills, and I lose so much on inclines, but not like I used to. Hoping this mod works out!!

Hey happen to have the part number on that PC3 box would love to test it out.

Just make sure you know how much more or less fuel you’re using when you change the settings. I’ve worked on bikes for over 20 years and I seen a lot of people blow their engine running it to lean. That box is an awesome mod If you know what you’re doing! I’ve never seen one used on a Jeep! Good luck

Hey man just wanna say I've been watching several of your videos these past few days and you are a phenomenal source of information. Your content is top notch, easy to follow and provides a ton of info. You should have a ton more subscribers. As a content creator myself I understand how hard it is to put together good content and not be valued for it. I have a question for you...its not jeep related but my vehicle is kind of in a small niche as well..and hard to get any aftermarket support for it....its a 2000 dodge ram v10 8.0 and it has cat removed high flow exhaust system, smog pump delete and that's about it. I'm wanting to play with splash mixing e85 or even home brewed e100 and came across your videos because of this pc3. Would this work if I added 6 more injector connections to it? Or is the entire module amd software only set up to run 4 cyl? Any suggestions to playing with fuel? I've been told that it should run fine with almost any percentage of ethanol while cruising low rps etc.. but at higher percentages of ethanol especially the computer may have trouble adding enough fuel at full throttle and start stumbling etc..I'm not sure I want to go with bigger injectors because I dont think I need to and I'd like the option to run it on all 87 when I want...I just need a simple way to adjust the fuel on the fly, and safely. I know I can spend big money on a new handheld tuner and their software package but something tells me there is a simpler way. I even thought that maybe I could alter the o2 sensor voltage to increase or decrease fuel but it may not be a fool proof method. Any help you can provide would be much appreciated. I hope your channel grows like crazy, and anyone watching this and learning from him the least you can do is subscribe. I'm subd! Look forward to seeing more. Thx man👊

great video what is the amazon link to those connectors? also what PC3 do i need to order for my yj

Man, this looks like a killer mod ! Well I don't think it would match very well with an Ethanol kit but it looks inexpensive and it could increase performance running on ethanol so no kit needed at all in the end. There is indeed a lot less performance parts for the 4 cylinders ! I done lots of research I managed to find out that you can at least have buff rocker arms that are interchangeable with the 6 cylinders it's a very good mod to have torque in further rpms and its a lot more reliable and knocking proof. Craziest and only big mod there's a company that builds Supercharger kit for the 150 cui ! A whole new intake bored for 6 cylinder throttle body all in smooth aluminium and reinforced injectors fuel line. Room is available for the power steering pump and basically you have a modified pulley and extrabelt to motion the compressor and feel like Mad Max with the YJ... For 2 500 $ !!! Nearly 2/3 time the price of a complete new block and assembled engine.

I'm getting ready, in the Spring, to rebuild my 2.5. When I do, my plan is to add the supercharger, port out the intake, add a 4.0 t/b, and the 4-barrel injectors. It seems the Dynojet tuner would be the perfect addition for all the other mods...right?

So, we both have OBD1, but I have a '93 Grand. I've done a few mods, but I don't feel the ECU is adequately compensating for them. Any idea if this might work for the 4 liter? Or is it pre-tuned to only adjust the injector pulse of a 4 cylinder?

I see there are many 4 cylinder pc3 boxes available. Does it matter if it is a GXS or some other motorcycle model?

Could you use a PC6 instead of the PC3? It's hard to find a new PC3 kit...which one should I choose (Harley or Suzuki)? Thanks in advance.

You and I got to Jeff about the same time. I attempted to connect mine and got the engine to run but it sounds like I am missing and the check engine light comes on. Jeff and I had many conversations about it and the wiring seems correct but it just won't run right. Pulled it off and haven't messed with it since as my trans was giving me issues.

Can you please add what fuel injector connectors to buy on amazon Thanks

will this work on a 89 Tbi 2.5?

next video there's gonna be smoke rollin from all four BFGs! #burnouts

Do you think that tuner will work on my 1988 S10 with a 2.5

Oh yeah. All the aftermarket support for the 4.0 lo fukin l

Look up 505 performance

Ok, so I think I have exactly the engine you have. My motor is a 4 cylinder 2.5 LT in a 1995 YJ. The beauty of it, because it’s an OBD 1, in N J our Motor Vehicles has exempted everything from 1995 back as they only use the OBD 2. Thus, no inspection required.

I must be really strange because not only do I want a 4-cylinder Jeep but I want one of the rare two-wheel-drive versions.
