Default Help me out! Worth getting a megasquirt over Emanage Blue?

Right so my head is fried at the moment trying to decide what to do. Worth pointing out firstly that I'm over in Ireland, which might make a small bit of difference regarding parts, prices and tuners.

But basically my engine spec is this:
1990 V spec model
gt2540 garrett turbo from r32skyline refurbed with steel internals 360 bearings blueprinted to engine.
front row engineering custom pipework with two extra injectors.
t house engineering intercooler (huge)
racing beat air inlet & k&N
LA motor co. oil pump &pipes ,oil cooler
walbro fuel pump
hks superdrager exhaust system no cat.
strenghened conrod bolts

Now the two extra injectors are controlled by a HKS injector controller

Right, so heres my situation. Looks like I'll be changing the engine. I suspect something in the head is gone, probably valve stem seals. Burning a mahoosive amount of oil, but compression seems good. But while I'm doing this I think I should also get some proper management, and injectors, and get the car mapped.

So my questions are what size/type injectors should I get? And what ecu? My two main options are the megasquirt and the greddy emanage blue. Now I like the sound of the megasquirt, and with the IAT sensor and stuff I could get rid of my AFM I understand. But tuning might be a bit awkward but ok. Its also pretty reasonably priced for what you get imo.

The emanage I am considering quite simply because there is one for sale for cheap. Great condition and comes with:
"Emanage tools and lead, a Flying miata 02 clamp, Greddy map sensor, standard and ignition looms and full instructions.
Not fitted since Ive bought it"


But AFAIK I wont be able to get rid of my AFM with this. So does it really make much difference? Basically is it worth paying nearly 3 times the price just to get rid of it, aswell as some of the added features of the megasquirt? Is the emanage blue any good? What kind of safe power could I expect, or what spec should I go for to have about 220whpish? Whats all this about a rx7 AFM? Who shot jfk etc.

I am on a budget as need to get a cage and plenty of other bits, aswell as seat time before the drift season, so price is important to me. At the same time I do want to do it once, and right.

So sorry for waaaay too long post, and any advice would be greatly appreciated, as not really mountains of info over this side of the world on the whole lot, and I need to decide quickly!

Cheers,
Brian

I didn't read anything, so I'm just answering the title: yes.

The CIA killed Kennedy.

And to answer your question: absofuckinglutely.

Is it worth paying that extra $250 bucks for a fancy hooker? Odds are they have fewer social diseases.

Plus they do the weird stuff.

All EMS are equal but some are more equal than others.

I believe the RX7 AFM can be used with no engine management to lean a car out a little at higher RPMs to pick up power. This would be irrelevant if you have tuning software. There are limitations to the size of injector the emanage can control which may be an issue, some cars also have problems with the stock ecu interfering or compensating for the changes made with a piggyback (honestly haven't looked into it with a miata). It seems that most of us feel the megasquirt is so inexpensive and versatile that almost doesn't even make sense to consider another options.

Standalone systems (Megasquirt) are better than piggyback systems (EMB) because you aren't fighting the stock hardware to accomplish your needs. Half of the work with a bandaged piggyback system is overcoming what the stock system is working against you to do. Being able to remove the large restriction of the AFM is a nice benefit as well. The RX7 AFM is slightly larger and allows a little less restriction, but isn't as nice as removing it all together.

As for tuning, once you have the base map on the MS and TunerStudio installed on your laptop, there is no reason a competent tuner familiar with other tuning software would have much trouble with it.

But have ppl not seen good results on the EMB? Its a case of the EMB costing maybe E250 and the megasquirt + all accessories costing about 600-700ish (both before mapping). Thats a big chunk of cash money for someone on a budget. I know a standalone is better than a piggyback, but in my situation will it make all that much difference?

Yes.

Go drive a car with a shitty bandaid setup.

Then drive a car with a properly set up megasquirt/aem/whatever.

You will notice the difference.

Sounds good. That pnp for a 1.6 mx5? But its more so when you ad in the cost of the IAT sensor, the 02 wideband and whatever other bits I need?

Any thoughts on injector sizes aswell ppl?

E440 is for a completely plug and play setup for a 90-93 1.6 and includes the IAT sensor. You will need a wideband, but you would need one anyway with the EMB. And that price is for an MS2, not an MS1.

Weener!! Cant say no to that. Details? Thats to Ireland yes? Any suggestions what or where to get the wideband then? The LC-1 is the usual way isnt it? And is there anything else at all I'd need (not including a new intake pipe) to get it going, aside from bigger injectors (again any suggestions?).

Get the newer Innovate MTX-L. UK seller: http://cgi.ebay.com/INNOVATE-MTX-L-A...item45f78df018

Price is posted to Ireland.

Re: injectors. How much boost are you going to run and are you going to be using the stock fuel pump or are you going to be using an upgraded one, like the Walbro 190/255?

Well it was currently running 0.8 bar (11.6 PSI) so probably stick around that. Basically I just want in and about the 230-250 FWHP range ideally (more is always better of course though). Dont necessarily need anymore than that, so whatever boost I need to run to hit that, but that I can also run reliably too. But if more is attainable safely then why not!

Supposedly has a walbro fuel pump. Not sure whether its a 190 or 255 though. Mean to check that.

Did you bother to go to the section I mentioned? Did you bother to follow the advice of people trying to help you and check?

I don't think anyone here has yet made 250 FWHP in their Miata. You will be the first.

We aren't trying to steer you wrong. Why do you doubt the help you receive at every turn? We aren't out to get you. We are trying to help.

No bother mate. Think we're struggling with inter atlantic communications here lol! I'm very grateful for all the advice I've been given so far. I have gone through the 12 page thread and am currently about to send a pm.

Regarding the 600-700 quid comment. Well I wasnt aware until it was pointed out later on in the thread that I would still need a 02 wideband with EMB. So even E440 plus 200ish for the wideband does still equal the 600-700. I also wasnt really aware that I could get it delivered from the states to here through Braineack. But that was my own fault for as you said not reading enough before posting again.

I'm guessing also that you think by FWHP I meant front wheel horsepower? I actually mean Flywheel Horsepower, which is generally the standard for measurement over here rather than WHP.

But anyway sorry if my comments seemed like I wasnt listening, it was the complete opposite, I just wanted it to be explained to me why aswell, as I like to understand these things as much as possible.

And so far from reading more and more I'm guessing 460cc injectors from an rx7 would be my best bet? FC or FD?

FC 460cc injectors are cheap and plentiful and fit well without issues.
