Soo my best friend who is my tuner threw out the idea of converting my CA to be run off a Honda ecu, ignition and harness.

So im like why the **** not, theirs soo much aftermarket tuning support for hondas.

Anyways the main concern I had was how am I gonna mount the Honda Distributor to the camshaft.

Well some of the honda distributors are actually very simple. Take a look at the ends.







Soo one way I thought about doing it is by making a adaptor on the cam gear where the 4 bolts are and weld a female end to the adaptor, maybe have it professional milled through a friend.

Heres what im talkin about.

[

The rest is simple stuff like wiring, adding Honda sensors etc etc.

Now your probably thinking why switch over. Well why not they are great systems and with Neptune its insane. Also I havent seen it done in the Nissan community, Toyota community do it quite a bit. Plus I love pushing myself to do new things.

Now dont get me wrong their is nothing wrong with Megasquirt, I love the damn thing couldnt be happier with it, its just I like to try new things see if it can be done maybe give someone new hope to give it a shot. Look at when I did megasquirt it was practically unheard of in the CA, KA community and because of my help and write up its becoming insanely popular. Plus im thinking converting to Honda stuff will cost less than megasquirt too. The ecu can be had for about $17-$50, a harness about $30-$50 as well, sensors for about $50, than its pick your tuning software. I will be going with Neptune and is $100 license fee but unlimited tunes afterwards.

If successful expect a full write up with tons of pics.

ecu themselves are dirt cheap.

This is what my friend charges for tuning.

Neptune pricing:

$200 for a n/a street tune and purchase of the lease.$300 for FI street tune and purchase of the lease

Dyno is $165/hour with everything included.

Mostly honda tuners use their stock ecu's and use software for tuning.

not such a far out idea........ special since late 80s CRX(IIRC) ran low imped injectors just like us. as long as fuel and timing are correct why should it matter who build the ECU?

seems like you could go standalone for same price, less effort and have more control over the system as a whole. but i honestly don't know a ton about hondas. not to criticize, i'm just wondering.

I Already have a standalone its called Megasquirt.

Anyways the cheapest standalone is Megasquirt which starts @ $189 but that doesnt include harness, sensors, etc etc. You can easily hit $400 with megasquirt.

With the tuning software the honda ecu becomes a standalone. It has 24x24 maps launch control, antilag, PWM boost controller, preset boost levels for different gears. So say 3rd gear is 20psi and 4th gear is set to 12psi.

For more info on Neptune which is what im gonna use

Are the quoted prices meaning, he tunes it on the dyno, but you can still mess with it yourself ? Since you're indicating it has all this tunability... realisticly if you had to pay $200 every time you changed something (as opposed to just when you get a pro to retune it), ordinary standalone would make more sense real fast ...

Oh ok I wasnt sure what you meant.

You can tune it yourself just like a standalone. When you use the aftermarket software you pretty much convert the ecu into a standalone.

You can not change the tune with the software he is going to run. Only the tuner can. It is not $200 each time. That is be the same for a standalone. It is tuning prices NOT hardware. What standalone can you get for $200? It also has check engine codes.

being a passenger in a neptune car and hondata car you can actually feel a difference, the neptune car felt significantly better.

I drove a neptune tuned car and I was extremly impressed.

S300 is ~$550. That would not make sense. I am not a fan of hondata. They have more bugs then I software I am using. More info about the software: http://www.hrtuning.com/pages/category/neptune/

LOL, julian, you are crazy. Hondata is not that bad. You are thinking of crome.

No honda motors usually spin counter clockwise, CA's spin Clockwise.

oh god. lets crap this thread to hell too.l

the way you are looking to install it, it will end up rotating the same way as it did on the honda engine, only you will be on the exhaust cam instead of the intake cam, if you are using a dohc dist.

sohc idk.

the kind of timing lag between crank home on the ecu/dist combo vs the ca idk.

I believe we are gonna use a P28 with a EK/EG harness. I'm not quite sure. My friend has it all planned out.

We are not going to use a P28. CAs do not have vtec, so no need for it. We will be running a P06/05. I can always add vtec if I need another output.

John, those are not my drawings. Your "problem" have a very easy solution.

Does the non VTEC have an output to use to control the secondary butterflies? Or have you removed them?

So, I assume that you will need monies in order to do this. How much for your MS? I am getting my tax return this week, so I am itching to spend it on something.

ummm we already have everything. Good morning is a honda tuner/specialist so he practically has everything. If I do have to spend some money it will be so miniscule cause the stuff is cheap.

Got my tax return 2 weeks ago another reason why I dont need money :D.

If this does work and I decide to stick with the Honda ecu than I'll probably sell MS for about $650-$700 which includes ecu, harness, edis package, sensor and bracket, and crank pulley in exchange for a OEM pulley.

If you're running a JDM head, you'll need that RPM based output to control the butterfly valves.

I'd use the P28 ECU, or if you're set on the P05/06, then add the VTEC circutry.

Hondas have butterfly valves too. They have a curcuit in the ECU for them already.

I have 7 outputs and PWM outputs.

Honda ECUs even have a LCD screen http://www.hrtuning.com/pages/...w-lcd/
