i still say stick with a s13 de ecu.
less shit to deal with, more tuning options. if you want to clean it up, you can wire in things like the s14's internal coil distributor, etc.
not that the 95 is a bad setup, but s13 is more common.
i also live in the land of rusty nissans so s13 mechanical and electrical components are more common then good bodies, so there are lots of parts available cheap. s14's on the other hand are still a lot of money if in good shape, and not nearly as common.
and i have looked at my fair share of harnness, ca18det's into datsun 510's, ca18det and sr20det into s13 and s14, s14 ka into s13's etc.
Full Version: S13 vs. S14 electronics on KA24DE
The '95 ECU has more provisions if you plan to custom tune it. Ask Jim Wolf.
'95 is the sweet spot year for electronics and KA24DE... all the newest goodies, but riiiiight before the OBD2 hassles.

ask 99% of people who are beyond just bolting on parts, jim wolf sucks.
You are the only one who says this. In all cases. I'm not a JWT pusher, but the shop has been around for a long time and was programming KA ECU's for along time, too. I'm inclined to listen to what they have to say.
my m30 has it on the vg ecu, i am using it to turn on my aftermarket fan, comes on at about 180 degrees.
and im not the only one to say this, do a search.
maybe i shouldnt say sucks, but not worth the premium price they charge for very basic ecu chipping, with generic maps.

Actually it's not "basic", if you did your homework on JWT ECU reprogramming, the price is a bit over $500, which for the features they give you for it is a typical price. I've seen some ECU reprogramming for other car platforms in the $800 range. Considering JWT will allow for you to specify things like RPM range and fuel maps (think turbocharging), I'd say the price is pretty damned reasonable indeed. The S14 OBD1 ECU is very flexible.
you're right, ive never done my home work and i dont know anything
have fun with you guestimated ecu chip tune.

This seems to also reflect the views on KA-t.org, which thus far seems to have a great deal of experience pushing stock electronics to their limits.

ECU/FUEL MANAGEMENT:
This is an area that can certainly be debated until the end of time. The two clear choices (and only choices IMO) are Jim Wolf Technology and RS Enthalpy. Clarke at JWT has been tuning Nissans longer than most of us have been alive, while Scott has been an SR20 mastermind for Southern Florida. Enthalpy tunes have across the board made between 15-30 more WHP peak than JWT tunes (who is on the more conservative side). Both options will work fantastic, are truly plug and play and is simply down to your personal choice.
Now there are always those looking for cheap ways (aka shortcuts) in their turbo setups. Enter the ApexI “Super AFC” and the Greddy “Emanage”. Both of these management options will work, but will require tuning in order to get the right result. Both options in my eyes, are simply cheap ways out initially. Once people get them tuned ETC, it would have simply been cheaper in the end to go JWT or Enthalpy.
Lastly, there are always standalone options. I’m not going to dive into these options, but you will undoubtedly get the most power from these avenues. AEM EMS, Haltech and the sort will require tuning (and some require complete rewiring of all factory wires.) This choice should be a choice for turbo experts, and are not something to even consider for a first turbo setup. Again, these options are very expensive and will need to be tuned.

where did this origionally come from? ive heard lots of good things about jwt and am interested in a ka for my project car. could you point me in the direction of the origional conversation? thanks

But I moved everything pertinent to this discussion to this thread.
I've been pouring and pouring over achrives and recent threads on four different major 240SX forums, and Jim Wolf is given the nod of approval from all of the more established (and more accomplished) KA owners.
My buddy used to have a tuned Hardbody and a Frontier, this was back in '03, and he kept insisting I look into JWT, and at the time, I used to laugh at him for tuning a truck engine. Of course now I have major egg on my face and I still hear it from him now that I have a KA24DE in my own car.
The bottom line is JWT has been around for a LONG time. They don't really design new new shit for the KA's, because frankly, they have that engine covered, and can pretty much make you whatever you need, or have it already on the shelf as a stocked item. I'm sure there's a statistic out there of people who are unhappy with their JWT experience, and some others who belong to the Enthalpy camp, and swear by them instead, but really, either shop is able to equip your KA for maximum output if you have the money, and both shops are comparably priced from what I have seen.
Oh, there's probably one other statistic of JWT bashers... those guys who think they know better and can do that kinda shit themselves, or claim they have "a guy" that can do this or that or whatever. Those are a minority statistic, the smallest one as far as I can tell.
So do what I did and decide for yourself what you think, after browsing around on a few 240SX forums.

If you had an early model S14 KA(95, early 96), the ecu also supports full OBD2 diagnosis without having it be a pain in this ass. This makes troubleshooting much easier. I believe you only have to wire in a diagnostic port for it. Sterling was looking through the diagrams and found all this out. I just wanted to add some extra information on it. As for ecu options, you can always get a bikirom or nistune for either ECUs and have a tuner of your choice do it. Even better is if you do it yourself.

that was my reason for saying jwt sucks. not so much that the product sucks, but the value sucks.
i think i stated a that already.
I'm not sure why you think the value of the product sucks. Maybe you stated it in a way I didn't follow... so you should explain. Not because you have to prove anything, but I honestly want to know why.
Are you talking about what he said there?

im rolling 95 stuff. the 6400rpm sucks, but my engine bay is relatively clean. theres not that much extra bs, infact i took alot of shit off. jwt shit does suck for the value. i want to find a good daughterboard setup maybe thats MAP compatible /ramble
