Ok it's time for me to ask a lame brained question that's going to get skeeted on by every "Im a DIY","Read the FAQ","Do some more research", jack hole who happens to read this.

I know it will be expensive.
I need an ECU.
I have been looking at Apexi,motec,TEC3,AEM.

I've called a few places to see if it would be compatible. They say it can be done but the cost for wiring would be about 1000$.

Does anyone know of a good replacement ECU, aftermarket/adjustable is what I want.

Please don't refer me to the JWT ECU. If i had a spare one to send I would do it. Since I'll changing some things on the engine I want an ECU I can adjust.

Let me hear if you've got first hand knowledge or a good hunch about were to look.

 

The AEM is Nissan compatible????

There are no replacement ecu that is adjustable. Unless you want to piggiepack the stocker with E-manage/Apexi SAFC etc......

JWT ecu. All you have to do is buy another cheap ecu and use that while yours is being worked on. Much cheaper than the standalones. Rework is about $100 a pop.

Standalones are about your only choice. Over $1,000 to buy, whatever $100s to install and whatever $100s to tune with a dyno. Unless you have some extensive experience on your own.

High boost = high money. No way around it. Especially with those tiny VG injectors you guys have.

 

Alright, first thing. You need to set goals for where you want to be. You have to pay to play, so set realistic goals. Also, you don't neccessarily have to spend a ton of money on a stand alone to have adjustability. You can get other things that are cheaper. They will give you adjustability, but maybe not as much as a stand alone.

For instance here are my goals:
200-250whp
Be able to run the car in the 14's
Streetability
Ability to control boost (like at the track I want to turn boost up, when driving normally, turn boost down).
Still be able to pass emissions
Keep an ideal level of reliability.

You can't just say hey, that's cool, I want this, and not know the implications that are with it. Also sometimes, certain things maybe way more than you need and often overkill. Look at the guys with newer gen boosted cars. Often a lot of them have at least $5k wrapped up in thier car, just to get to 300whp. A lot of these guys spent a lot of money just to get everything to work together.

My 2 cents.

Good point both of you.

Thou my goal is for 300hp/250whp.

I'll be changing the intake manifold to the 300zx, and using 370cc injectors. Still haven't found the right turbo yet.

I just want to be able to program the ECU along with the changes in my car. I still need to drive it for a couple months.
So in the long run Im thinking it would be worth the money now, to keep from having to pay after every mod to get the car to run right.

Like sarin, I want a beast at the track and yet be able to pass emissions.

 

Using the 370cc injectors is opening a whole big can of worms regarding getting your setup running right. An aftermarket ecu will be a must, unless you can fiddle with a SAFC and the fule pressures. Getting a setup like that to pass emissions will be bear at the very least.

I think the most you guys can reasonable squeeze out of your stock injectors and raised fuel pressure will be about 200-220fwhp. That could "probably" be done on a small turbo, Walbro pump and a Vortech FPR with the right disc. Easy, fairly cheap and should last if you don't get greedy.

Want more than that and you will instantly need to add $1,000s to the ante

 

To be honest, the stand alone would be overkill for the numbers you want. You can easily get away with adjustability using E-Manage, S-AFC II, and what not. Plus, from my guess of things, if you get the stand alone, your not going to know what your doing, and something isn't going to get set right...and POP! there goes your motor.

Most of these come from shops that install and tune. So the price usually gets you an install.But not all the time.
I want to pass emissions but im speaking about the present. I need to pass now, registration is due. After that I don't care.

There will always be a curse on this car. People see the potential and just wuss out.Any car you setup to play with is going to cost money. Some more than others but if we don't try we don't know.
I know you guys have looked into this for your cars any promising leads? Any?

Oh yeah have you heard of the Nissan ECCS (jecs)?

 

I'm looking to use a Cartech/BEGI FMU 2025, myself for starters. Then I might look into a S-AFC, or probably a AVC-R. That's what I've been looking for.

As for the Nissan ECCS, that is what we have in our cars. It's the entire engine/fuel management system.

This is a good thread.

 

from what I was told by the AEM customer service guy, they can be made to work with just about any import. The hitch is you have to have it wired to fit your vehicle. We never hear about it because honda guys have so much support with there older cars that most aftermarket companies will make a specific application just for them.
If we had more people trying to mod there 1st,and 2nd gens there would be a bigger aftermarket for it.
Hence we would have adaptors for our cars. But from the myriad of times ive been told to sell my car,or you cant do that it will cost money. I understand why honda is so popular. If we had half the aftermarket they had I would of boosted my car by now, and probably crash into a ditch somewhere.
All it takes is just one. Once we get one souped up 2nd gen, and more people say they can do that the larger the market will get for our cars.

OK
Sorry about that I really like the 2nd gens.
What was the original question?

 

for honda's u can find part at any k-mart lol

 

AEM is supposidely has one of the best stand alones you can find too. One thing though is, where do you draw the line? I get the samething from other people when I mod my car, but so far, I haven't done anything outrageous yet. Everything has been towards much smaller mods. There has to be a limit where we have to say...this is way too much.

That true
But screw that.
Wouldn't you love to see a production of aftermarket mods for our nissans?
I would. Hell you guys could probably sell the design of that CAI to a company. You just have to show them that people will buy it! That's another reason that I want more mods for our cars. I want AEM, and Motec to make ECU's for our cars. And yes I know "overkill","too much","too far".
I think we have one of the strongest engines around. Mine has 239k and it still pulls hard when I give it the gas.
I know you guys think that I'm blowing smoke but when I buy stuff for my car I like to research... a lot.
I say screw the ricers out there, you know the ones with the under chassis lights,and the flames on the side of there car. The kid whos parents bought them a car when they were 14(okay now Im just hating).

Long story short we have dope cars. Nobody makes enough aftermarket goodies for them. Only way they will is if we step up. Might have to pay,or make ourselves. Is it worth it?
HEELLLL YAAAHH!

 

Problem with AEM. They have to crack Nissan's ecu codes. Only a few companies have done that. ie.. JWT.....

 

Im not 100% on this but I think they have. Im sure there are 240zx running around with those. The guy said since my car was so old he couldn't just match it. He said I'd have to have it wired to match the AEM.

 

Yeah, and they were only able to crack the codes up through 96...and anything newer hasn't been done.

S

 

Yes AEM has quite a few Nissan applications. Mostly the 240 sr20det, 200sx, some G20 apps etc..

 

Basically if your going turbo and intend to make more than 240whp, you will need to get 440cc injectors and a Z32 MAF. All you'll need to get is the ecu programmed for those injectors + maf with turbo and you'll be set. After that you can get an adjustable FPR to play with A/F ratio, and play with ignition timing if you want.
