I couldn't wait 'till 7:00 AM...

I deleted all the crap in this thread. Let's not have a repeat. Butters, the 280zt ECU uses only one coolant temp. sensor and it is located at the base of the head, between cylinders 5 and 6, passenger side. ...And you should expect a PM in your near future.

Heath was *incredible*. Best super-hero movie ever filmed... I'll be making another trip to the cinema.

Actually, it has an AFM. No MAF in a 280zx No such thing on a 280zxt. The turbo has an integral mechanical wastegate to regulate boost. The ECU doesn't even know how much boost is being generated... it simply meters the air via the AFM. The advice given, regarding your writing skills, is spot on. Please slow down a bit, proof read/spell check before you post, and it will make things much easier for all of us.

garvis, If you're inquiring to understand how this applies to MS, this thread will be nearly useless. And honestly, I'd rather not drag it off track any farther. However, I did hear a rumor Matt Cramer with DIY Autotune is/was working on a replacement disk that WILL work with MS. Give him a shout... http://www.diyautotune.com/

Finally getting around to posting a pic of the amended manifold, installed...

There's no end of opinions on AC systems if you Google... everybody has their own 'right way'. Keep in mind system pressure is subject to ambient temperatures so you'll want to watch out for that trap. Most pro-shops would prefer a full vacuum and reintroducing a known quantity of refrigerant and oil. Gauge's are a great diagnostic tool, but they don't tell you how much refrigerant is in the system, at least not directly.

Actually, I was thinking about banning you

Hugh answered your question.

Have a good one!

Yes Sir, you would be correct. And you should be wholly aware that that doesn't give you right to be an arrogant prig. Let me make something clear. I value the members of this forum. I will not allow you to treat them like dirt, regardless of who's right or wrong, who does 'better' work, has the larger penis, etc, etc. In your 6 month stay with us, you've contributing absolutely nothing of value to our forum. I have no reason to believe you ever will, so why should I allow you to continue your membership with us? So you can pop in now and again and tell people everything YOU think they're doing wrong? Sorry, but you haven't earned that position. You are welcome to share your work, your ideas, teach and learn, as long as you extend some reasonable courtesy. This is your first and only warning. Treat these members with some respect or your membership will be terminated.

Check the gland nut on top of the struts (the nut that holds the cartridge in the tube).

Stock Ljet can meet that goal. I didn't have a specific brand in mind, but Megasquirt will do. Yes, batch-fired. Yes, Sequential. I get the idea that two things are attracting you to the Mopar... Closed loop and Sequential injection. Sequential injection will only help incrementally. Its not the end-all be-all in EFI. Don't put all your eggs in that basket. For example, there is a member here with a 280zxt, running 7.4:1 CR (not exactly ideal for MPG), getting 30 MPG (hwy) with a sequential (aftermarket) system. Here's the kicker... he's never timed his injectors to the valve events. He has no idea how far off the events may be. So, did he get lucky, or is it just not that significant? Closed loop is the mixture trimming I believe you are referring to. Keeping it simple... this is only happening under cruise conditions and the target is 14.7:1 AFR. While 14.7 is the best compromise for emission's, it is not normally where peak MPG is going to be found. Leaner, much leaner in some cases, will usually net better MPG. One could say... the idea you're holding on to, is actually working against your goals. Disclaimer: I've made some assumptions about the Mopar EFI based on what you've given us. If your information is wrong, then so is mine.

Hi Raff, Asking for the engine to 'limp home' without a CAS is like asking for a body to 'limp home' without a heart. The CAS is the only sensor that provides engine position information to Wolf. All ignition and injection events are established by position. If that position is compromised, Wolf stops all injection and ignition events until engine position is re-confirmed. Imagine the potential consequences of injecting/igniting willy-nilly

Why? What kind of MPG are you looking for? An S30 with LJet can pretty easily get 28mpg (hwy), 30+ if you work at it. The hurdles you must overcome to make your idea work would take more effort, and likely money, than an aftermarket EMS. And, I'm betting, less fruitful. In my opinion you're going about it the hard way.

A bit off topic perhaps... I spoke to my local car audio chap about this and he was reasonably confident that a 35lb (pull) solenoid would do the job. They are approximately 2" in diameter and 3+" long. Need more? He can also get a 65lb *MONSTER* at about 4" in diameter and 7+" long... probably fold the hatch in half

Its not your dropping resistors... there are six in the pack. Not all of them are going to fail at once.

Sure have. Many people have removed the well for one reason or another (fuel cells probably most common). I did it for exhaust.

Interesting thought.... but the ring & pinion will be running backwards. Not sure if diff integrity is the same in reverse. The off-road crowd would probably be able to answer that one.

Interesting location for the KS... I like it

Use to be (extracts). Haven't brewed for close to ten years. I've forgotten most of what I didn't know, so I'm not one to offer anything useful I still have most of the paraphernalia. I keep toying with the idea of starting up again... but life keeps getting in the way.

Still a few things on the To-Do, but we get a little closer every year...

Please take the advice given seriously. We appreciate your desire to help, but if its not coherent, its useless... or worse. Thanks.
