Default Megasquirt - What's REALLY wrong with it?

Been looking in to it to run on a Scooby engine that I'm putting in my Beetle, and all in all it looks awesome for the money. I've spent the last week or so looking over the software (Including third party software, Megatunix etc), MegaManual etc and it doesn't seem too bad to use.

However, after searching around on various sutes, forums etc some people still have a low opinion of it. What, if anything, is bad about it (Hardware or Software) that causes a problem for a novice user? I can understand professionals having problems with the way certain functions work, but as someone installing and tuning it as a hobby/bit of fun is there any REAL downsides to it?

Cheers for any input

Non varnished boards etc, its just not made to the standards that a professional ECU are.

Fundamentally though it DOES work, the software works well, it copes with transient fuelling well and loads of people have success with it.

Just bear in mind than a low injector voltage at some point in the future with a bit of corrosion could cost you an engine!

Seems to be the biggest downside to it, I've found this place: http://www.diyautotune.com/catalog/m...nit-p-165.html

That sells them pre-built with surface mount components, people seem to praise the build quality of them so may be worth a shot. Though to be fair, 300bhp in a beetle and I'll probably kill the car before the ECU gives in

Generally though it all seems very doable with a bit of common sense, and if I get stuck there seems to be enough info about to read up on... Sooo tempting

i think it's because you build it yourself rather than buy a preassembled ecu and fiddle with it to give you resluts that puts people off

if you are capable of doing the stuff yourself then fine and dandy, but a lot of tuners won't fiddle with it for you as if it goes pop on their rollers you might be expecting them to pay out for fixing a problem that you created in the first palce

There's a lot of paranoia about it, and it's pretty unfair. Most MS ECU's in use are professionally assembled, not that many people are confident enough to build their own. You can buy a can of conformal coating from RS to protect the PCB from the environment and then it's very unlikely you're going to have a failure.

I used one on my 24v and it was great, loved the software and had the car runing in 20 minutes using adaptor loom and just pluged it into the ford loom

if you get a pro built one, they are great

Nothing wrong with it at all.

If you buy a surface mount board from one of the good suppliers you will have no probs.

Im finding the surface mount boards a ballache at the mo, as they are really only suitable for EDIS. No ignition drivers, and no 5v or ground switching for COP with igniters without additional boards.

Aye, TSR and DC Customs can do the conversion and adapt a standard loom, but for what it costs I think I'd rather do the conversion myself and spend the money I'd pay for a Scooby loom and ECU to be adapted on MS

Bug looks lovely mate, you still got it/Have any plans?

yeh i only used them for advise really, would have done the work my self

saddly no, i wish i didnt as i can probably say i will never get the chance to buy another 1949 beetle!!!!

I did a full restoration on the chassis back to standard with cables brakes and the body was sandblasted remounted and primered.

i also collected 80% of the parts to complete.

Some one offered me, back in febuary, Ł8000 , as a rolling primered shell, so i let it go, as i kind of lost the passion doing it stock. if id have kept with the scooby idea i would have probably still had it now.

they are worth up to Ł25k fully restored

heres how it was sold


I also sold me escort cossie 3 weeks ago, so went comfort shopping in the classifieds and bought a 71 beetle for Ł200. i also have a 500bhp V8 and lots and the words steel tubing, mid engine, space frame. floating in my head

for anyone who things beetles are slow, check this out. and this aint a scoobie engine its an old flat 4 aircooled vw engine!!!!!!!

Hard to say no to offers like that I suppose

Anything planned for the new Bug?

Mine's nothing special, just a '75, widened fibreglass wings, bump steer kit, castor shims, beam supports, KYB shocks etc etc, never bothered with dropped spindles, don't like the ride they give at all, suspension work is done, just need brakes to match ready for the new engine.

Had enough of aircooled engines now, blown a proper spec engine, and a standard engine way too expensive to tune properly IMO, Scooby conversions just seem so right when you take fuel economy, price, reliability etc in to mind. And having looked at some of the 1/4 times they do, even better... Bug with a ~200bhp Legacy engine + 65bhp of gas is doing 11.2's

Few pics of mine...

I will baltantly plug the place I bought my MS2 V3 from - www.extraefi.co.uk - 12 months return to base warranty on parts and labour, 100% support for the product via email and telephone and an excellent service from a professional in the electronics business, who also happens to be one of the developers and designers - you won't go far wrong if you are buying from Phil

Been looking at Phil's site, looks damn good... Added to the list of resources I'm stockpiling

Scooby conversion is getting common on them mate, Porsche engines have pretty much always been a no-go, the "Porsche engine fits straight in" phrase is a myth tbh, much more work to Porsche engine one.

Scooby conversion pretty much comes down to a bellhousing adaptor, running some coolant lines, mounting a rad and a few little bits like throttle cable etc.
