SR ECU to Control KA

[Chezedik]

I searched, and I know this seems like a stupid topic, but here it is. There is a guy on campus here at my school who is running a KA-T with all SR gear (or at least that is what I was told), and what I am wondering is if I were to get all of the SR gear, would it be possible with modification to run the KA w/ it or is it just ridiculous. I assume it is the later because of the direct ignition, but I would like some serious input.

Ive never heard of anyone trying it, because of what you already mentioned. Direct ignition has to be computer driven, without computer feedback from RPM's it has no way to manage fuel input... Just guesses, I could be wrong.. I mean maybe it gets feedback from the throttle position for fuel management. Im not an expert on these particualr computers but I seriously doubt someone could run that setup without some serious re-programming.

I think I have heard of people doing the swap though, using the DE distributor instead of the CAS so that they could wire it easier rather than doing direct ignition. So if the KA distributor could provide the same signal and allow it to be distributor-ed, then I think it would be the same. Admittedly, there wouldn't be much to gain except maybe a little bit easier boosting by going with all SR stuff.

are u not paying attension there was a post 2 days ago Jeff Tyler it was called 420hp ka , something like that !Thats sr coil packs and ecu on ka . but as far as learning how to set it up do ur reasearch, its complicated its not like changing a light bulb .But it isn't that hard if you know how efi works.

Are you talking about Kintaros White S13 coupe?

He's using an SR ECU

[Chezedik]

Yes, I am talking about his coupe. I have yet to meet him to see it, but I like what I have heard. And I am not on that forum, but it is good to hear that it may be able to be done. I think it would be important to use oversized injectors, but the timing should be good. As far as the article, I am glad to see that and have saved it in my favorites. I will want to look more into this. I think the SR will give coil packs and better timing. But how to wire it up. I see it as an inexpensive solution to the engine management question. Probably just right for a budget setup.

[Chezedik]

BTW UCant, where are you at in Frontenac? Do you have a 240, and what is done?

[scarboroughdub]

the only benifit is the individual coil packs per cylinder, if your planning on running more than 500whp than i would maybe consider this option.

other than that the stock ka ignition system is still very capable.

[Chezedik]

I was thinking the advantage was the turbo timing map in an ecu that is relatively cheap. Also, I still wonder about using the distributor (CAS) signal to act as that from the CAS on the SR. Like I say, I read about running the SR with the distributor. However, I wonder how much misinformation was out there when people first started doing SR swaps. Anyone with an idea?

[180sx]

dude turbo map from sr ecu? so get biki and duplicate sr map into ka ecu.bin . sr ecu and ka ecu are the same just different maps go eccs.hybridka.com

[Chezedik]

That isn't a half bad idea either. Everyone tells me about biki, but I cannot find any real info on it. Every time I get a link, it is a dead one. Do they have stock SR maps on ECCS, I haven't looked all that hard, as this is just a thought.

[S13.5_92]

why couldnt you use one out of a front wheel drive sr20 turbo the come with a distributorin the back of the head wonder if that would work

[Chezedik]

That's what I mean, if it triggers the same it would be a cheap way to go. Has anyone done this? I know of the other fellow who did it direct fire, which is cool, but I just dropped a ton of money on this distributor, and even then, he must be using it or something like it for a trigger.

[S13.5_92]

im not sure im not an expert you can probally check with the transverse sr guys but i do think it has a crank sensor and the ka has a magnetic in distributor you could just get you a fwd sr20det ecu and hook it up and as long as the magic smoke that makes it work dont come out and it runs i would run it the you could have the fuel maps and all you need if you try it let me know and if it works i want to do it

[Chezedik]

Nope, in the KA it is optical. But otherwise.... helpful. I am wondering if the CAS on the SR will work to signal the ignition.

[UcantDrift]

His car doesn't run the SR engine controls, just the turbo off one

[Chezedik]

No, I understand that. What I am suggesting is that you can get an SR ECU for cheap, and apparently, it can be ran with a distributor. So, what I am suggesting is that it could be done, not that it has been done. There are a few more posts in here than just the one referring to him.

I am actually working on an adapter board to mate S14 KAs to the S13 SR Power FC (which should work with SR ecus also).

It's been done before using coil packs as stated above, but this board will eliminate the coil pack requirements and simplify installation with a plug & play solution.
