Quote from: "silversprint"The PFC has no knock control. This could mean life or death for your engine, specially for a very fragile 2zz engine with a turbo. I have the PFC and had to add a J&S safegaurd at an additional cost for knock control. I wish I had the choice of the AEM EMs4 to start with.  The EMS4 is a much more capable unit with internal datalogging and knock control.

You can order an EMS4 with plug and play harness and base map from monkeywrenchracing.com.

Autotuning with copilot only works if you know what your are doing. It's not as easy as it sound. I spend hours with copilot. In the end I just took it to a pro tuner to clean it up.

The only worry with MWR plug and play harness is that they are configured for the US harness and ecu pinout. (Different part numbers for US ECU.) I know our Australian harness/ECU is a bit different. Your harness/ecu would be too? Do you know anyone who has successfully used the MWR EMS4 harness in your part of the world?

I am leaning towards the Link G4+ Storm ECU for my build, either ECU costs more than the car though!

Link ECU storm G4+ is a fine bit of kit.
I was looking at the Fury better for 6 cylinders and has built in AFR.
Still think the ECUmaster is worth a look for the money.
First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me.

I have gone with a Link G4+ Xtreme ECU, includes traction control so saves money on a Racelogic setup.

That's what I'm running the 2GR with, but not using traction control.

You can't get racelogic traction control anymore.
Unless you see one on eBay.
Good ECU. Ends up costing 2 grand by the time you get all the proper link sensors looms etc.

I've just had MegaSquirt thrown into the mix.
I know it's big in the US on ye olde muscle cars but it seems to have really picked up pace in the meantime with V3.

Any experiences?

I really like the "open source"-ish/raspberry-pi-esque approach they take. It's very hands-on, but also very accessible and full of great features. And..cheap!

Even has mobile/tablet apps to tune it with.

AEM (according to MonekyWrenchRacing) is a bit of a handful with an overwhelming interface, but very feature-rich and a well-established user base.
Then there's the Link G4 Storm, another proven great piece of kit but a bit higher on the prices.
And not to forget Emerald K6.

I know that the Megasquirt is quite popular with the MX5, I think the issue we have with our cars is that you need to have a fairly good ECU setup to be able to control the VVTi system properly.

It looks to have pretty decent vvt control in the 3
Knock control with a separate module.

That Megasquirt setup sounds interesting Schnazzle. Please keep us posted.

Don't have it yet  s:) :) s:)
Don't know if we'll get it at all. But it is very nicely priced.

The K6 comes Pre-configured to run the car for under 750. Also very good feature set.

The good thing with the above is that you don't need bay expensive separate tools or software

Do they do a plug and play harness for the Megasquit?

shnazzle

#37
Nope. I haven't even found a 1zz plug for it so could be interesting. Worst case scenario you get a universal adapter for the 1zz and wire the MegaSquirt into that as to not have to cut into the stock wires

It's the home brew raspberry pi part that puts me off.
I never even bring it up when people start talking ECU.
Makes perfect sense if you like to tinker yourself.
Just not for me.

I think it's come a long way from being that home-brew solution (which it totally was).
It seems the MicroSquirt took over as that when the Mega matured.

The software looks really good and mature, and the hardware solid.

It's no AEM,link or SyvecsS6 but it's in the same league as apexi and Emerald

Knowing someone who used Megasquirt to run a V8 and the issues he had with it, I'd give it a wide berth.

Aha
That's the stuff I was looking for.

What kind of issues? Would it be relevant to the turbo 4cyl setup?

Can't remember, I'll give him a shout and find out. I remember he was very unimpressed with the customer support.

And there's that "open source" feel I mentioned.
It's very much a community thing from what I can tell. Massive forums etc.

As Scott pointed out though... Not for everybody.
I'm 50/50. I love tinkering but it has to be rewarding.

What about Emerald? Better?

Mike's reply to my question:

"Hi Chris, I wouldn't do it..  doesn't work out much cheaper than an omex/ emerald system and cost is supposed to be a selling point. It's ok if you are a electronics expert and want to build and learn about ecu's but no good for a plug and play type approach. The ones you buy ready built are of debatable build quality, built by amateurs for enthusiasts with too much fiddling and tweaking to sort along with poor support.
 
I still can't get a cam signal so run batch injection which negates the extra cost of the version I bought. I've an omex 710 which will be replacing it when I can be bothered.
 
If it's for a 4 cylinder (full sequential setup) an emerald K6 or omex 600 are the weopons of choice
 
Mike"

I know he's been trying to get it running right for ages (V8 in a tiny kit car). So there you have it.

That'll do me.
 No MegaSquirt.  s:) :) s:)

Thanks Chris, very helpful indeed.
From the sounds of that note it also seems to address my question about the Emerald.

Certainly not in this to mess about. Access to tinker, yes. But there's tinkering and then there's re-engineering to get something to work.
No thanks on the latter.

K6 does adaptive AFR mapping which I don't remember the last time I had a look.
Being designed and built in the UK has to be a good thing.
At the very least you don't need to call New Zealand at 1 in the morning for customer support.

I wonder what the boost control is like. Overboost protection is a nice feature to have.
While the boost cut it causes can be.. Err.. detrimental.. to the car.. Not having it would have been a lot more detrimental.

Does K6 run OK on MAF? Or would we have to switch to MAP?

To be honest, I'm about 85% certain I would do the bulk of the "Getting it running" and then drive it to a mapper to sort it out. That should save hours of dyno costs

I just had a very quick look at the Emerald K6 spec web page, it only mentions MAP (not MAF) but doesn't mention knock control at all!
