Can you even tune the 94 PCM?

Isnt that the crazy OBD 1.5?

Yes. I've been tuning my car for almost 2 years and 35k now. People run from OBD1/1.5. I have no idea why.

Currently I'm using TunerCAT RT, and an Ostrich emulator. So, I can make changes while the car is running and if I have a co-pilot, while driving. This car never saw any MAF manipulating devices.

Why are we even talking about PCM's instead of a standalone fuel/spark management system? Has anyone even seriously rationalized the gravity of the 'wish list' here?

This is truly impractical on so many levels. I'm not beating on anyone's here, but we need to stop and think. The S1 L67 is not suited for what is planned. Nobody knows that better than the Zilla. If I knew THEN what I knew now, I wouldn't have done it. Is it fun? Sure. When it's all working right. Is it worth it?

I'm beginning to wonder.

Bill makes a great point.

I'll echo it again, there's not one reasonable reason, to use two M62's over any of the other different SC's available in any market. Hell, two M90's will make less heat, an M112 work nicely as they're OE on 400-500hp vehicles, and a KB will demolish everything... If you're building a custom manifold, you can make whatever you want. Don't cripple yourself to an M62(s). It's like spending $40k building a Factory Five Cobra Replica, and putting in a 3.8v6 from a mustang in it because you have one lying around and it's convenient.

If you think it's something unique and will impress people, it's unique yes, but anyone with a lick of how to build a performance car will ask themselves, why on earth did you spend all the time making it more complicated, much heavier, and less reliable when there are better solutions out there. Have you ever picked up an M62? One on the top of the engine is more than enough weight that high/forward in the chassis, adding another blower + a heavy ass manifold will only make your car handle worse.. Nevermind how the hood will look when shaped around such a setup.

As another red VW owner (albeit a MKIII owner, those punks) pointed out, You would need double your OE fuel system capacity, the fuel pumps alone will run you over $1,000, lines, another 300-400 atleast, injectors and a custom billet fuel rail system? Don't ask. Your fuel system will be worth (over $2,000?) more than the car when you started out.

Stock PCM? A "Local tuner for $100"? If this is your budget for the "brain" of your system, you need a budget re-evaluation. You will most likely want something you can tune yourself, probably a standalone system, something like megasquirt, most likely tied to a full MSD ignition box/setup.

No one has put 500whp through a 92-95 H body that I know of either. Just looking at what the chassis will need to cope with that is scary. Traction bars, new tie rods, new ball joints, new bushings for the control arms, if not tubular control arms...

Jason, Megasquirt and MSD +4 would actually be on the menu for sure.

Sadden, you should price those out. And that's just for CONTROL of the hardware.

Wow now you guys are really trying to scare him off. You dont need megasquirt or MSD.

I wanna know who has paid $1,000 for a fuel pump? SERIOUSLY You could go fuel cell, AN fuel lines, custom fuel rail, and injectors for $1000 maybe a tad more depending on where you get things.

Scare him off? Not in the least. We're answering his question based on our knowledge.

So you're suggesting spending 20% of his proposed budget on fueling, and we haven't even added any power yet? Good start. That leaves just enough of the budget for his trans and a tank of fuel.

All we need now is the custom manifold and bracketry to support the extra hardware up top, cylinder heads, and a bunch of other stuff including the valvetrain.



The point we're making here is that he's chosen the wrong car to do what he wants on the budget he has. A much more likely scenario on his budget? That's something to discuss. He's not going to get 500 reliable horsies out of a Series 1 on that budget. Not even close.

Well now im torn. I talked to the guy the other day and he said he would do the custom parts no problem (minus the programming) i found a place to do tuning but i dont know if i want to anymore..

Depends on what you want. Reliable?

Who's doing the cylinder heads? Which cam? I think you need to ditch the double charger idea unless you make one of them a turbo. We can still work something under that hood with what you have to work with.

That was the whole point of this idea "with what i had to work with" im not gonna have the money for a turbo and intercooler setup..
yes reliable. i want do do up a daily driver that i can thrash all the imports with. Drive to the track run low 14s and high 13s give the car an absalute thrashing and drive it home again...

What they are trying to tell you is that with the money you have, you won't be able to that either, at least not with a twin supercharger set-up.

You don't need twin blowers to hit high thirteens.

Cam, P&P the LIM, SC, and maybe the heads, smaller SC pulley. Valvetrain support (new chain, probably stiffer springs). If the car is a 92 or 93 L67, do a Gen 3 M62 and TB swap. And then get a dyno tune. You'll be consistantly in the 13's. Stock injectors might do it, I don't know.

I want to do heads but idk if the ones i want to get (intenses) will fit / work
and the tranny is sounding like a killer right now

Intense's heads won't work for a Series I.

Yeah, the tranny would break after a little while. Maybe $1500-2500 for a rebuild that will last. That doesn't include a beefed up differential.

And that puts us back at stage one then.
I can make the tranny work with my budget but everything after that gets all sketchy

That is why most people do it in stages (atleast I do) as the funds come in, you get something new.
