Wish me luck, gonna convert to Honda ecu.

[blueshark123]

Great shit man i got to give u props on trying this i love how easy it is to tune my brothers car with hondata kpro. gl

[MegasquirtCA]

Thanks guys I appreciate all the positive support, makes me want to start on this ASAP. What Im gonna try to do is work on the Distributor part first this week or next week. My friend has a distributor lying around on my days off I can start mocking things up. If I can make the distributor adaptor work with nothing scraping/rubbing and turns smoothly than I KNOW we can get the sucker running b/c thats probably the BIGGEST hurdle.

[johngriff]

Lukes right.

Why the hell use honda ecu?

Use the GM setup, that makes 10000 more sense.

The other thing about there being "tons of support"

You really just need to tune the car correctly, without stuff breaking, to make reliable power when running. Were you not able to do this with the megasquirt?

Well for one if I use the GM setup the price for that will be nearing $1000.
The tuning applications I looked at such as HPTuners, EFI Live start at like $500, plus you need PCM, harness, according sensors.

Also we have the honda stuff laying around so theirs no startup cost other than adaptor fabrication.


If you read the thread you'll notice I said that megasquirt is fine been running it for 2 years now, this is just something I wanted to do before I did MS but I did MS instead.

This is not julian

Whats wrong with a honda ECU? Maybe you do not know what you are talking about. It does not matter the ecu. GM setup would not be 1000 better. Considering I tune both

You will have to talk to julian about megasquirt. I have been bugging him for months to tune it. The honda ecu will be cheaper then MS and have more options.

If you want to check out the software we will be using, you can see it here: http://www.hrtuning.com/pages/category/neptune/

lol

I don't understand...if the guy can do it for cheap and has the resources/help, what's all the fuss about?

I don't understand getting frustrated/mad over something that doesn't effect you. Am I missing something?

[bongnak]

what obd is the gm setup? or does it not matter?
i like the honda idea because it's extremely simple and effective. With an emulator tuning would be a breeze.
- idle control is coolant dependant, not electrical so no worrying/wiring there.
- the only thing i dislike is that you wouldn't be able to use external coils easily

It will be running a IACV, so it wil be control by the ECU. You are thinking of the fast idle vavle.

External coils are cake. I have made 650whp on stock honda ignition. I doubt a T28 will make that much

hahah youre right wasnt thinking right it's been a while, 650
what coil setup was it? an external msd type thing?
this is gonna be fun

[MegasquirtCA]

Nope, Stock internal honda coil, ignitor, distributor, cap, rotor, everything. You could add a external coil (MSD or Honda). I do not think it is needed

[MELLO*SOS]

Cool project! Should be "fun" getting it going... In a DIY sense of the word "fun" lol.

Does the honda just use a regular external coil and distributor, or is it a special kind of distributor with a built in ignitor/coil? I see the plug on it so I assume it doubles as a CAS (like the KA dist).

Update the thread as you go, I'd like to follow your progress.

[MegasquirtCA]

All the position sensors are inside the distributor. I am not sure what distributor we are going to run, but it can be a external or internal. Both distributors have the ignitor inside.

It should be fun.

dam hands down goodluck man

Yes for good reason to help you. Thats what the forum is for. Honda made that system for it's economy cars. You want to take a superior nissan DIS system throw it out the fucking window and go on a custom fabrication rampage. Why not just put a FR mounted S2000 motor, if your so hell bent on using the INFERIOR honda ignition system? Ive pushed C18 and SR DIS past 420-480 whp personally with no hints of misfire. I Know that it can take more, Nissan designed it from the factory to be ready for JGTC and any thing else frankly

Yes this is a project and no im not an engineering major, Im just looking to try new things, we dont move forward without trying new things.

This is no different than someone switching to Haltech, Megasquirt, AEM, SDS, etc etc

No your right this is like blowing your foot off with an M80 insted of eating a steak

Just because I dont do it the way you would do things doesnt make it wrong.

You mean Just because you want to something completely pointless doesnt make it wrong. Well it does. It's completely pointless.

But its ok Steve I got the same type of shit when I first started my megasquirt quest and it took me completing it and getting it running to convince the nay sayers that it was an option.

Right and megasquirt sucks too, If it didnt you wouldnt be at the cross roads of "oh man I better grapht over the entire ignition and electronics/ems system from ANOTHER FUCING manufacturer"

Honda already made it on their car, the research has been done the verdict is in and it works! Honda's engineers made a great system for Honda.

This would be like going through the effort of putting in a weaker ford crankshaft and going out of your way to do it to prove (what point?) I don't know.

Just buy the propper EMS and start tuning your car already.

Tell me exactly how the cost/benefit analysis of this transpired in your head?

Look I honestly commend your insanity and resourcefullness but just remeber McGuiver has been scratched from prime time.

It just drives up shits creek (not really but internet wise) that people who want to "race" their car cant pay about 2-400 bucks more for a read standalone system that has support, history in racing and ease of setup, + warrenty and is a long term investment that in most cases can be swapped from car to car, depending on future projects.

Get out there and race already FACK!

Your decisions are like paradoxical beach balls bouncing in my head now.

[S14DB]

Why didn't you program the CA ECU to begin with?

[johngriff]

I already asked him this about 900 threads ago.

Apparently there is something monstrously wrong with the CA Cas that I have yet to experience. With his advice I picked up two more cas's at the junkyard for $10 each, and have been waiting for something to happen.

[KiLLeR2001]

What's this crap. Keep everything Nissan or GTFO! Puma stop wasting time and go powdercoat something.

[MegasquirtCA]

It just plain sucks, the coils overheat, the cas breaks too many times, little to no aftermarket support.

hah man it almost hurts to read what you write. I have read atleast 5 different points of your's that single handedly discourage ingenuity and preach conformity.

You sound like a communist and if you did actually have the opportunity to run a society, there's no doubt it would be stuck in the stone age. If you think there's only one right way to do things, you have a lot to learn.

Your comment on the Honda engineers making a great system for honda makes you sound like you drive a honda. It's still just an engine, the aspects it has that make "it work!" can be applied to other engines as well.

Lastly, to actually contribute something useful so the OP doesn't have to say again, he can get the stuff for < $300, and has access to machinists and honda friends. He's got the cost portion down, if he can make reliable power that matches or surpasses other standalones then I'd say his cost/benefit analysis was done quite well.

[steve shadows]

The OP is useless to begin with.

Why bother contributing to it?

Your above comment just exemplifies redundancy of all of this. Redundancy equals failure to operate your life efficiently. At least in most cases, there is not need for such a contingency on something already properly engineered. It's like getting the contract for the F15 with Pratt and Whitney engines, and switching to Rolls Royce right before going to market. Total FIAL

Communist? Communism was the critique of an existing capitalist system that offered a competitive advantage to those to analyzed the cost benefit process properly to come to a marketable conclusion that could be brought to market furthering the utility of man.

Communism was critique that tryed to create a ass backward pitch patch of other philosophies to counter an already existing perfect system.

So your a fucking communist.

Look Michelin already tried to re-invent the wheel...it turned out? well fucking horribly, talk about a waste of a firms time which = money.

Time = Money

you are wasting your time bastardizing your car with pretty half hearted excuses for why OEM equipment fails in the first place.

Case Dismissed

FACK THIS IS FUN, MARIA THE EXCITMENT HAS ME EYEING THE INTERNS AGAIN< GET THEM OUT OF THE OFFICE >

wow people will go out of their way to avoid doing something right.

I havent even gotten close to tapping the potential of the E8 I have and ive nearly maxed out my setup on 91 octane.

Haltech is plug and play works the same way a oem ecu reads crank trigger via stock crank trigger, and if you get the E11 you can run a v12 formula car off one if you wanted.

Good luck in the frontier of money burning.

Are you an engineering major? is this a project?

this is just insane and pointless imo.

I second this post haha..

There is no Nissan part that will solve this problem?

Why don't you switch to ford? with mechanical fuel pump and single cap and rotor ignition that is even "easier" to tune than Honda.

[MELLO*SOS]

I find it funny how much it matters to some people what some random guy on the internet does with his time and money..... Are you his wife? Financial advisor? Manager? LOL... Just because you don't want to be bothered with it or can think a more simple/expensive solution doesn't entitle you to bash the guy for doing something... shall we say, "unique". Fuck just let him do what he wants, and prove to us that either A) The honda setup sucks and has just as many problems as the CA/Nissan/MS setup or B) This setup was cheap and effective for him. Either way, none of us are out anything by him taking the time or spending the money to do this. We can follow his progress, and laugh at his mistakes or learn from his experiences... Who fuckin cares...

I don't understand it either why he doesn't just perfect his CA/MS tune, but maybe he's bored and looking for another project. Who knows.

And you know it could be worse... At least this isn't another thread about how to bleed the cooling system on a KA or asking if some 17x7 +35s will require a pull & roll LOL ... No offense to you guys bashing the guy, but it's obvious he doesn't care what you have to say and your posts are unlikely to change his mind.

[MegasquirtCA]

Half hearted huh yea bro thats why im constantly seeing threads on how the moon shaped key broke off, that the coils are constantly overheating causing misfire even when they are brand new. Its 1 thing if it was a case here and their but this shit is WORLDWIDE.

Megasquirt does suck thats why Parish went from EFI Live to Megasquirt
http://diyautotune.com/cars/customer...urbo_truck.htm He could of kept that GM system but went to a shitty inferior standalone.

Dont go putting words into peoples mouthes just because you cant read. I've said a bunch of times and I'll say it again, I'm not doing this because you think im having issues with MS, im doing it for the fun of it and if successful a way for others to achieve the same results.

I have only seen one Coil go out. Seen more SR coils go out then CA.

Never seen a CAS break unless it was in shipping.

I have about 15 CA ROMs on the shelf and a ROM burner. It's just like tuning and burning any other Nissan ecu. It's easier that an SR or DOHC KA. Like the SOHC one ROM to burn no splitting across chips.

CA ROM tuning is a cakewalk compared to the SR IMHO. Only problems I have seen is with finding CA mechanical parts not engine control parts.

[johngriff]

even if the key breaks, the cas is still fine.

I have put together a bunch of rb's and ca's that had broken keys. Its not a big deal.

Haven't had any problems with coils.

You could retune for different coils with a ca ecu based rom tune.

BUT PLEASE SHOW EVERYONE HOW SUPER THIS WILL BE, I WILL ONCE AGAIN BE BLINDED AT THE MIGHT OF A HONDA DISTRIBUTOR ON A 1.8 L

MSCA, have you thought about posting this over at FA?

Do they really have the support behind them that Honda ECUs have? I've honestly never bothered to look.

[bejota180sx]

wow good luck with the insane project, it sounds crazy but if it works out well yeah you have a kickass project under your arms hahahaha

[MegasquirtCA]

I just want to thank everyone for their support, I received pm's, instant messages, and rep praising me on taking on this challenge.

I've collaborated with several people, even the creator of Neptune. To see what issues might pop up. The biggest issues were mounting the distributor, and the speedo.

The speedo may be taken care of by using a signal converter board that the Neptune designer will proably make for me to use. When we get to that point we'll investigate.

But I'll pretty much start off with a harness already I believe off a EG or EK, than remove what we dont need.

Anyways as I was researching on the capabilities of the Honda stock ignition see what limit it can go. Supposedly somebody dynoed 731whp but I cant find a dyno sheet on that.

Another one I found was a 1.6L Del Sol with a t3/t67 did 615whp

Heres a link
http://forums.evans-tuning.com/viewt...?p=15533#15533

15psi on 93 Octane




30psi

[blu808]

Mad props on making that power with a honda engine.

But it looks kinda funny to me. I am used to dyno printouts curves that are more like a square than a ramp.
