Better than Megasquirt?

[Speedtouch]

Been perusing Miller Performance's website, hoping they might have some Xmas specials, and I see they now offer a very promising sounding standalone engine management system, the MMS 1.3

http://millerperformancecars.com/latest ... 3-ecu.html

Just wondering if this would offer the same level of control as Megasquirt?

Sounds quite a boon for those of us too lazy to change all the engine sensors and wiring loom...

[dannyboy759]

looks quite good, sort of thing i was looking for to be honest, but how good is it?!!!

[dannyboy759]

no one have any ideas?

[appletree]

would have though this would have got more intrest in the F/I section.

I was told that cosworth engine mangement is very good if you can find some espcialy onj a 4 pot like the IS

[daimlerman]

This looks good.$645 is around £325 so well cheaper than the kits.And you get $150 (£75?) off for returning your ECU.And the ability to ajust fuel/ignition yourself.What are the snags?

[FlappySocks]

Good price if it is Megasquirt (dont forget to add import duty/vat). If its propriety, then i'd prefer to stick win an open standard. Lots of development, and new features being added to MS all the time.

I'm making a few Megasquirt based ecus at the moment, that use the new Megasquirt SMD boards inside a Motronic gutted case. Not all that hard to do. I will have some more details on them over the next few months.

[FlappySocks]

Reading into it a bit more, it's not MS. It requires an AFM or MAF. Doesn't look like it does any additional spark output, so you can rule out wasted spark. Makes you wonder if it's nothing more than a processor board that plugs into the existing eprom socket of the Motronic ECU. The only thing going for it, is that you can just plug it in, and not have to do any wiring.

If anyone gets this ecu, guranteed i can make one like it if i was to open it up and see the contact points, as regards to the connection location onthe inside!! its a basic cable location to the pin out points on the ECU circuitry that convert to the 9 pin serial connector and the software that comes with it... nothing hard.....but very cleaver!!

So in a basic sort of way,this modifies the motronic to allow DIY ajustment?

[ShepsEvo3]

Looks ok to me and pretty simple to use, but to get the best you'll have to tune it on the dyno.

Dead handy that its a plug and play. Would be interesting to open up that ECU and see whats been done.

Yes! But I question its definition, ie fueling can be adjusted in increments of 1. Which maybe ok, but for ultimate fueling you may need a fraction of 1. Unless 1 is a pretty fine adjustment. Same goes for the ignition timing I suspect?

[daimlerman]

So for around £250ish you can have the ability to set up ignition/fuel DIY on a rolling road.All we need is a victim to try one...

go on then

I'd be up for having a go at mapping one for someone... But remember, remaps are not "cheap" and when you think of the Dastek Unichip/Q which is a piggy back ECU can do the same as this, maybe its not worth it?

according to dastek about £464 for their product

[FlappySocks]

It retains the AFM (unless you buy an expensive MAF to go with it) which is one of the top reasons why you would want to dispense of the stock ECU in the first place. Then to benefit from it, you will need to get it mapped.

Add a wideband O2 sensor to MS, and it will tune as you drive for similar money. Plus you get proper spark control (wasted/individual coils)l, and all the other goodies, like anti-rev (traction control), air density correction, etc etc

Uni-Q is £295+fitting and mapping. Plus you can run without the AFM and even a MAF, you can run a MAP instead if you want too aswell. So not much difference in cost, plus there are alot of dealers in the UK.

But hey, I aint bigging it up as I am biased I guess.. although the straight ECU swop does look appealing.

I've been thinking about this a lot since reading yesterday and like some of the points about I can't get my head around it.

The expensive and important part of "tuning" the car, as they call it, is the mapping. Even if you can map yourself you really need a rolling road. Really looms are easy, and aside from the odd annoyance like having to make up a timing wheel if required, aftermarket management is simple to fit.

This may well be around half the price of some other management solutions, but it has all the limitations of the original system, which for me would be the main reason to change the management (namely running an AFM). In 99.9% of applications I can't see where this setup would actually be of benefit.

Basically, if someone is expecting to buy this, whack it on, change a few numbers around and suddenly find a load of missing performance then they'll be very dissappointed.

[DaveD]

I take your point but I feel that if you have modified your car, changed to a MAF and are thinking of further mods this might be an alternative to getting someone else to do it for you evry time you change some part.........

[boombang]

I'm confused a little from the lack of much real info on that site - I was assuming that you'd be stuck with an original AFM, but with my lack of BM specific knowledge not sure what Motronic and sensors they actually run on M20 and M40.

If this system allows you to remap accurately via TPS and MAF rather than AFM it's worthwhile, as that makes it far more suitable for ITBs or turbo applications.

I know that Motronic 3.1 uses MAP, TPS and MAF as have a full setup here, and IIRC 1.3 has no MAP sensor, again making it suitable for ITBs when remapped.

So it might actually be a very good solution and me just not knowing what I am talking about - it has been known before.

Well I certainly don't...i rely on people like you

[daimlerman]

I am wondering if this is my way forward to sorting my fueling issues,mapping on a rolling road is both expensive and time consuming,if I can do tweeks using a laptop I can confirm my ajustments on a rolling road day at a more modest cost.But at the moment I seem to be groping in the dark...

[FlappySocks]

You will remain in the dark until you have some sort of feeback of the fuel mixture. A wideband o2 sensor will cost you about £150. But then you will either need a display for it, so you can manually make the adjustments, or plug it into an aftermarket ECU, and let it do the tuning for you. You could always sell it afterwards if money is tight, or use it on another car.

Looks to be a good toy , but lacking any real development potential.

if the plug and play option is whats getting most people interested there are PnP MS units out there or buy a JPT55 connector( £30) and fit that on a short loom for a plug and play MS unit.

cost it all up with a WB02, MAF and connector plus the mods+ mapping and its not quite as good value as it seems.

TBH, I have an Emulator and can map Motronic in realtime so no use to me, otherwise I'd get one and have a play.

Anyone gonna take the plunge ??
