I'm looking into a standalone for my 2wd and i'm leaaning toward building and mapping a megasquirt v1/2 . I'm fully aware that it's no simple task to map an engine correctly but i'm very keen to get into the mapping side of things. So my question is why ins't there many people running them on YB's?. Is it purely because chips with a pre installed map are realitivley cheap from reputable tuning company's and most people are happy to go down this route of am i missing somthing ? cheers in advance

i think the reason is two fold
1) as you say you can buy a eprom preloaded for very sensible money
2) reliability and quality assurance of something you solder yourself, (and im a fan of self learning)

Thats a good idea Tony i would be far happier with a plug and play option so to speak . I wan't mad keen on the idea of rebuilding a loom to suit and changing the sensor's ect . To be totally truthfull i wasn't aware you could map the weber units . Any more info on getting a hold of one ? cheers Al

having gone the megasquirt route on my various builds of engine over the years it's great in many respects, very versatile unit.
however and it's a biggy, it takes time, fuel, more time, more fuel and patience to get your mapping skills good enough to get it nice to drive.
pay a mapper and let their years of experience save you a fortune in time and fuel.
if you really want to learn go for it, i haven't had a failure of ecu at all, just wanted to learn and thought i'd save loads, handy as i've changed spec loads of times now.

Thanks for the reply , I do wanna learn and the car is only a toy so doesnt matter if it's off the road or uses a shit load of fuel it's gonna be a steap learning curve . Now heres the thing do i as Tony said find a t2 /T6 or build or buy a squirt system ? will the pectal units support coil on plug as thats one thing i do want ?

Again , i didnt know you could hack into the mapping on them , what would you need to change to break into them , chip only ?

Piems is a DOS based program, yes of course, as all the MAPS are just copies of the original Ford software.
You will need an EPROM reader (Connects by serial port typically) if you want to see and manipulate your current MAP, alternatively there are plenty of maps out there you can load to explore and play around with.
This is ASSUMING your chip is not encryped, MSD for example protect there chips to stop people from stealing, meddling with the maps.
So far as I know though with the Webers you will have to erase and reprogram the chip each time, which will require more hardware, i.e. UV lightbox, as it's not something that can be done dynamically, although I think RP Labs may be able to utilise a data stream IIRC.

There may be some additional wires but most should be covered with the patch harness. Ive done it before wiht other ecu's
One thing that would be good to get rid of though is the crappy 4 tooth crank trigger.

Been doing a lot of research over the past few days and i've decided to build my self a megasquirt . Up to now i'm thinking a MS2 v3 with mapdaddy upgrade however thats subject to change . Gonna steer clear of the ms3 at the moment as theres not a stable code avalible as yet that i can find and i'm not ready to start delving that deep as yet . As a nice extra i'm going to build a megaview so i can get rid of my AVCR and let the ecu control the boost solonid or air injectors not made my mind up yet then build it into my dash like the SECS do . Very tempted to scratch build a loom as the ageing ford unit may cause issues, Plus i can revert back to Std if the need arises . Steve i'm currently looking into a trigger wheel to get rid of the lugged artical so whether it be a case of mounting a 36-1 trigger wheel for now until i come up with a more asthetically pleasing solution still remains to be seen . So as im a big kid ive been to Maplin today and splashed out on a new soldering station with adjustable temp as my gas one's arn't suitable for the job . Thanks to everyone for there sujestions and help . Oh and as a point to Beatlejuice someone has run MS on there lawnmower ,Look it up
. I'll start a build thread as soon as the preverbial wheels are in motion as i'm sure i'm going to be needing lot's of input

Yea, just use a 36-1. Although I'd just be buying a fully built unit if I was doing it
The notion of self build is nice, I really wouldnt be arsed when someone else can do it. It would be hours of my life wasted lol

Fuck, I just checked the price on them, no way would I use one. They haven't got low impedance injector drivers so you have to use ballest resistors.(yuck)
So you want high impedance injectors , the ecu itself, a wideband system, a way to listen to det, you've spent over a grand before you know it.

Overall they are still cheaper. But IMO not cheap enough to make them worth it.
As much as I was against the use of resistors too...many OEM's do it, so it obviously isnt as bad as it sounds.
But with MS you are tied to using the Ford EDIS ignition system. Which I guess is ok.
Just depends what you want really. I prefer just to buy a quality product that I know works and there is support for.
Everyone who has MS says the support is great too though. But it seems a lot of features require extra code and there is lots of software fucking about to make stuff work.
But even a fully build MS3 does seem to require extras to achieve basic stuff that other branded ecu's will have already

It seems MS can be versatile, but it doesnt come fully capable out of the box so to speak. If you want options, they need to be physically added, or extra software/code added.
I'd rather just buy a unit in a quality enclosure with proper quality connectors that simply works.
The only MS unit Ive seen that comes close to quality is the Microsquirt that Trigger wheels sells.
All the others just look cheap and nasty. Maybe a small issue for most though.

We have found that in comparison to a Megasquirt, pound for pound the DTA S60 is very cost effective...
Phil @ Extraefi builds a relly good unit but for ease of learning mapping from scratch I'd go DTA every time...S60 can do COP, MAP, TPS, Launch, ALS, Flatshift and Closed Loop, with an external controller...
DTA also has a fabulous Oscillation function that lets to decode whatever trigger wheel you are using....
T6 is very very good, difficult to configure in someways for a novice....never used a T2...
