k24 engine management
 

I've got a k24 bottom end and I'm going to put a k20a/a2 head on top and use an rsx-s ecu. I need a cheap, reliable ems that can be tuned on my own without a hondata dude holding my hand. Will megasquirt work even with the weird O2 sensors the k-series have and the vtc mechanism, will it drive the stock gauge cluster too? If not, does anyone know if there's a way to socket the rsx-s ecu's?

simple answer k-pro.


Gotta pay if you want to play.


No support for the k motor in the free world.


Read about k-pro and the k series and reality will sink in

Yet.. :)

But yeah, go with Kpro.. all the K20 guys over here are mad about it.

Re: k24 engine management
 

ghey. i figured there had to be another way than hondata. Guess not. Thanks though

edit:

hey do any of you guys know if I'll run into any problems with using an rsx-s/tsx ecu and which year/one is better?

Re: k24 engine management
 

If it's a turbo car, you can run most anything by way of EMS and just let the intake cam stay locked at 0 degrees, since that is where it likes to be when boosted anyway.

But if you are worried about having to get a Hondata guy to hold your hand through tuning what is basically an OBD1 Honduh interface w/ a half dozen i-homosexual functions added, then I doubt you could get through wiring in your own Megasquirt or the like.

I like K-pro. I'll post up a dynosheet of the last car I tuned on Kpro. Completely stock A3 (03 Civic Si) on 10psi. I'll be tuning it again because the goal is 400whp but the MAP sensor is definately going to need to be switched and a bit more tuning time will need to follow. It's do-able though, just some expensive engine management.

if you want cheap, just go with a vafc and an msd boost retard.

Re: k24 engine management
 

I'm not in the least bit worried about wiring a megasquirt and tuning it myself I just don't think it'll work with a k-series, the problem i have with the cheaper hondata's for the k-series are that they are "tunable only by a dealer with a K-Pro system" which is bullshit, I want to tune it myself and not pay someone to do something I'm capable of.

and I am planning on turboing it, but that probably won't happen for about 2 years. For now I just need an engine management system that'll work with my hybrid that I can modify for later on when I get reground cams and some boost.

plus I can just lock the vtc mechanism to keep the cam gear at 0 degrees.

by the way that ep3 is sick as hell. is that on stock internals/valve train???

Re: k24 engine management
 

Yes sir it is, Bone stock and I'm not done yet :D As for tuning the K-pro yourself I don't see why you couldn't. It definately takes knowledge of how the K series engines work (which it appears as you do) and will take some time learning the program but I know the dealer I work for that sells K-pro alway's supplies the customer with their copy of the software incase they want to do their own tuning. A dyno is definately the way to go with it though, not really something you can just tune on the street and call it a day.

Re: k24 engine management
 

why not? thats how i've always done my tuning. i'll leave the ignition maps at stock, get a good fuel map dialed out then take it to the dyno and let them work their magic from there. it saves alot of time and time is $ at the dyno.

Re: k24 engine management
 

Well, ----. If you've got that much common sense, why are you asking us anything?

I'm not being sarcastic, fwiw.

Re: k24 engine management
 

i'm too scared to leave the ignition maps stock, the motor is going to be n/a for a year or two with a vtc mechanism modified for 45 degrees of advance/retard. I'm thinking of using a ridiculously thin head gasket to bump up the compression a tiny bit, then when the turbo comes on, get a normal sized head gasket, rip off the vtc mechanism then re tune.

edit:
on the hondata website, it says the k100's are only tunable by a dealer with a k-pro system, which is the ghey one that's 600 and the k-pro is the one I want but it costs a shitload more. http://www.hondata.com/kproducts.html

Re: k24 engine management
 

Well I mean sure, you could work out your fuel maps on the street (which you should do anyway for a portion of the tuning) but the timing and cam angle maps will definately need some dyno time. These engines make their power through the cam degrees and ignition timing maps and trust me, theres plenty of them to tune... 12 ignition maps and 12 fuel maps total just to give you an idea :y
Brandston I'm not sure if they changed anything recently but I believe the K100 is not for sale in the US. I would have to give my opinion and say keep saving for the Kpro. You'll spend $600 plus installation fee's for the K100 when the Kpro is anly a few hundred more and will be much more valuable to you either under Boost or NA. I'd say it's the way to go.

Re: k24 engine management
 

yea that's what i was saying, i just wanted to make sure I was buying the right one. thanks for your input guys

kpro.

thats a plan...

K-pro or megasquirt. thats all you have really
