There's one single person on this board who has done it (and he hasn't logged in in some time), otherwise yeah it's not very common. What I'll likely do is do a dyno session where I plug the stock ECU back in and see how it does with that then plug the MS3X back in so it's the same day and the same conditions. Really the only way to do it. I'll probably look into doing it next month, there's a place here I've been to that's decent and only charges $50 for 3 runs... The other part of what I'm doing here will be finding other places that I can make power since that does seem to be kind of neglected on here. I don't really want to turbo my Pathfinder or any of that, I'd just like to get as much out of the VG30 as I can, and if that's still not enough for me then I'll do a VG33 swap. Gonna be so anxious for the postman to show up all this week

My TunerStudio running and connected to my MS3X with all knobs on my JimStim maxed.

It's a separate program. I just purchased it today along with TunerStudio MS. Actually just got done upgrading my firmware, I was still on 1.0.2, the newest is 1.0.5a, if that tells you how long it's been since I've plugged my MS3X in VE Analyzer basically takes your datalogging and crunches the numbers to come up with the most efficient tuning setup it can. It's a great first step before you take the vehicle in to dyno tune as it's based on your actual driving habits.

Fortunately I don't actually have to be able to write a good tune for it, VE Analyzer will provide a great starting point and I can have it dyno tuned later.

I'm actually going to run individual Chevy truck coils (the type that a lot of LS1/2 guys use) so I can take advantage of full sequential spark.

..... Spoken like someone who doesn't understand what I'm doing. I'm not interested in any of this, this is the path I am taking, and yes, you can tune in more power, it's not like the VG30 is fully tapped out from the factory. And nothing I'm doing will make anything "extremely unreliable," I can toss in the stock ECU at any moment, this is all going to be done without a single modification to the harness. Just watch this thread, I'll show you the way... literally, step by step. I'm thinking I should do some before/after dynoing as well. edit: I know I probably came off like an ass here, I just tire of these kinds of preconceived notions when it comes to tuning engines...

Megasquirt is a fully programmable ECU that also allows all kinds of awesome datalogging. I'm going to be able to tune the Pathfinder up to get me more power and better economy by basically replacing the ancient tech in the stock ECU with a modern ECU.

Well, found an ECU for 19.99 shipped on Ebay so I snagged it. Looks like I can get started much quicker than the 1st. Actually, I just ordered the LC-1 as well, let's get this shindig started.

I'm starting this thread a little bit early but next month I will be Megasquirting my Pathfinder. I originally bought this MS3X kit to swap a 3.0l I6 from a 2001 BMW 330ci into my 86 BMW 325e, and I've made plenty of strides towards that but still don't have the engine in yet. Money has mainly been keeping me back on that project. One of the things I've needed to purchase for some time is a wideband O2 sensor (I'll be using the Innovate LC-1). I'm a guitar builder but that doesn't pay the bills really and I'm also a college student using the GI Bill, which is my only real source of income currently because building guitars is pretty fruitless. Having recently totaled my 87 BMW 635csi hydroplaning during a really bad storm my Pathfinder has become my daily driver again. My Pathfinder currently only has 2 'mods', a K&N filter and I've bored the MAF .250" over. The MAF boring has really caused a hit on my fuel economy though it has given me a very noticeable boost in power. I'm only average 14mpg currently and that's on stock sized tires and stock ride height. I really like my Pathfinder, quite a bit, and seeing that it's my daily driver I've decided to convert it to Megasquirt so I can attempt to get a bit more power while also getting better fuel economy. So I've already built the ECU, I've tested it and it's working. Here's what I started with: Here's what I ended up with: The MS3X board isn't installed hence the open plug, it is installed currently though. My plan is to purchase the Innovate LC-1, a spare WD21 ECU (I'm going to attempt to build the Megasquirt into the stock ECU housing, using the stock plug so that it's plug and play, may pick this up earlier if I can find a dead one cheap), and this trigger wheel. I will be converting it from distributor type ignition to sequential ignition while I'm at it. I'm going to be looking into what 6 cylinder coil packs I can buy as well in the meantime... A couple last things, the Megasquirt uses a MAP sensor instead of a MAF so I'll be able to get that restrictive piece of crap out of the system. The other question I have is if there are any throttlebodies I can fined that have a bit wider opening that will bolt up with little or no modification? If not I'll send mine into MaxBore and have it bored. I've seen one thread on here about converting to Megasquirt (and turboing), but are there any others? I've already tried Googling but when I find anything VG30E related it's mainly talking about how you COULD do it, not about actually doing it.

Vendor forum, not Services Though I didn't even know about those until you posted and WOW they're nice looking. Do want.

Very nice, how does it feel now?

There it is in my Pathfinder. Yeah it's a bit dirty... It fits pretty snugly and doesn't intrude on leg room so I'm a big fan.

I use this: http://forums.bimmer...d.php?t=1830682 I originally bought it for my 87 BMW 635csi but since that's been wrecked I transferred it to my Pathfinder and it's actually an outstanding fit. I'll take a picture in my Pathfinder tomorrow, it's currently at a friends house.

Not really sure why you're getting so touchy here, you never indicated that you performed the connector swap in any of your previous posts. Just trying to help.

Have you moved the injector to another spot to ensure that the problem isn't the injector? What testing are you basing the idea that the injector is fine on?

I would contact the people who cleaned up the injectors...

I paid $46 for a gallon of this, it'd take a lot more than 4 rattlecans to paint a whole truck. I still have left over, I'm going to be painting the rear cargo area next.

It's lumpy but that not caused by the roller, just the way it dries.

Sounds like bull to me. Pick up some used heads and drop them in.

The knock sensor issue is a big one. You can't just bolt it to the intake manifold and expect it to work, AFAIK most knock sensors work by detecting a certain frequency, tuned to the material the engine block is made of. Attaching it to the intake manifold is attaching it to the wrong material, you need to attach it to steel, aluminum resonates completely differently from steel. You're basically going to have to find a spot on the block or cylinder head that you can attach it to.

Is that covered somewhere in the FSM? I'm on my tablet or I'd look through it...

I'm in love all over again and I've always loved my Pathfinder.

Front and rear bumpers done. Still need a grill, also need to replace the mounting points for the rear license plate, the plastic grommet on the left side is missing.

Really cool thread. I'm curious if some of the gains aren't because the MAF is bigger bore? Or is it? I didn't see it specifically mentioned in the thread. I bored my stock MAF .250" over about 3-4 years ago and the power gain was actually pretty noticeable. So was the gas mileage hit

Just noticed a spot on the drivers side fender that needs touching up and I still have to do the bumpers but I'm beat so those can wait for another day. Next up is to replace that screwed up grill.
