Hey guys, have any of you used megasquirt ecu's in the past?. I know a guy from europe that builds them. A few of the honda guys over here use them with good results, but from what I understand, its d-i-y tuning hence why not many people use it.

As far as I know, the ecu is sent out with a base map, then it has to be tuned with a programme called Mega-tune (which is sent out along with the ecu)

If I go a head an buy an ek9, dyou guys think this ecu would be a good idea, or should I stick to the the tried and tested units i.e. power fc, aem etc?

Also, mods wise, I'll only be doing exhaust mani and intake for the time being, so will an fully mapable ecu really be needed?

Thanks for any info
 
i believe the ecu has to be custom wired in, its a great unit for people who dont have a plug and play option available to them, like people who put rotary enigine in a rx-2 ro in a datsun, or any of those crazy swaps. its very popular among rotary people. i think you should stick with whats available plug/play. unless you know someone who can tune it at a great price and install it for cheap.

:nice:
Also, intake and exhausts systems are considered basic(external modds) and you do not have to change or touch your ECU for time being but as soon as you change it, these mods will perform even better!! :nice:
 
Thanks for the info guys. My tuner offered to map the megasquirt, on my starlet, but Ive not asked him about whether or not he can map one for the ek9. The guy who makes the ecu's said that if my tuner has mapped ecu's (he makes his owb ecu's for evos) in the past, he will definately be able to map one for the 9, as its just like mapping any other aftermaket ecu.

If I don't go for the megasquirt, what other alternatives are there? Is plug and play a good idea, or stand alone a better option.

The car is going to be my daily driver, with the odd trip to the 1/4 mile strip and race track each year, so what else would you guys suggest after exhaust, mani and intake? I'd love to do a turbo conversion, but I simply can't afford to go down that route for the time being:(
 
there are 2 types, piggy back and stand alone, most stand alones are plug and play which means you unplug your stock ecu and plug in the new one.

your optinos include

aem ems
hks fcon
apexi power FC
greddy emanege ultimate
hondata s200/s300
phearable.net chipped socketed ecu
haltech
motec


you have a lot of options.
 
Ah right. I was was looking into e-manage blue piggybacks ecus with all the relevant harnesses etc, but many tuners over here said they were a waste of time, and that I should get a stand alone instead.

I'll look into the ones you listed Blinx:)

What other mods would you suggest after intake, mani and exhaust ? I'm guessing its not easy to get close to 200whp with the b16b without going down the turbo route, as its a highyly tuned engine to begin with?
 
you can reach 200, it may be hard if you limit yourself to 1.6 but if you get a stroker kit it would be easy. after I/E/H you could get cams vavle springs and retainers, head studs and thin head gasket. if you have extra money you can stroke it to 1.8 using ITR crank rods pistons and port the head too. add some 310cc injectors a fuel pump and some kind of tuning and you should be good for 200whp :nice:
 
Thanks for the info bro. Great help as always:nice:

Where dyou get the stroker kits from? Also, I read on here that many use Toda B spec cams, as they give a nice increase in torque. What dyou reccon?

Many choices when its time for cams. :) My suggestion is the same as many guys here will say that either Toda Spec B or Skunk2 Stage II. You can pick Toda for more midrange power increase and Skunk2 for top rpm performance :nice:
Check out this link, its started getting boring posting it all the time :lol: but I think its a great feedback concerning cam decision.

Also, here is the thread about Skunk2 Stage II camshafts.

i vote skunk2 type 2, i dont think the toda b's are big enough to make 200whp with a 1.6 you can get stroker from a lot of places, spoon sells one for a reasonable price believe it or not. about 1100 makes it 1.8 uses stock itr crank rods and pistons.
 
Thanks again for the info guys.The plan was to reach 200whp with my starlet, so thats why I thought I'd aim for a similar figure if I end up buying the ek9.

In all honesty, dyou guys think 200whp would be a little too extreme for a daily driven ek9? Or will I be happy enough how the car would perform with mani, exhaust, intake and ecu?

Sorry for all the questions, Ive still yet to drive an ek9? (I will be test driving one next weekend:))
 
200whp should be fine. but if you want more, you always have the option of turbo :)
 
Man, I'd love to turbo one, but simply can't afford to at the moment:(. 200whp will be my goal, but I'll get started with a service (make sure everythings working ok) then start with the intake, mani, zorst and ecu. Hopefully that'll be enough to keep me happy for a while. As long as its as quick as my starlet (running around 160bhp at the moment) I'll be happy bro:)

The last reason to apologize in a forum is for making questions!!:)
I will place it differently and I will say that stock B16B is almost like a normal 1,6 L engine nowdays in terms of torque :( So, this engine will never become too extreme on public roads unless you like hearing vtec screaming at 9000 rpm!! If you really want to release enough power form this engine, then Intake - header - exhaust - ECU are not enough, you have to change also your stock cams for bigger ones + other necessary bolt ons and also to work on your head (port - polish etc)
 
Thanks ManosEK9. Ive been on a few forums where, members don't like having questions thrown at them, or simply just don't reply. You guys on the other hand have been super cool, and willing to answer all my questions asap:)

So to have a nice street spec setup, I'll need:

Intake
Mani
Exhaust
ecu
cams
port and polish

anything else?. I don't need a firebreathing race car tbh, as its going to be my daily driver, but something quick and more importantly reliable is what I'm after:)

Of course and you need not one but many things. Keep in mind that you cannot semi-built your engine both because you will not be able to get the desirable and promising results and also you will be running high danger of engine damage or rapid wear. So you also need:
1) A bigger throttle body.
2) Valvesprings and retainers(are a must when you change your cams)
3) Thinner head gasket

Now I might missed some parts but when the time will come you will learn more :nice:
 
good point manos! valvetrain is important :nice: having your intake manifold portmatched will help too. i recomend a AEB's 68mm tb. there good and cheap.
