** MegaSquirting a V8 - "Basics of How to" ... The A-Z Saga


Recommended Posts

Just answer your phone :P:rofl:

Nige

:rolleyes: Phone answered and lots of questions answered. :D Also HFH V3 map will be burned to ECU tomorrow, each day the Bobtail gets better and better. B)

Everydays a school day... When you want to look at a datalog file on the MLV make sure you load the right MSQ... it helps... :ph34r:

Had a go at the WUE today and it starts a lot better but lets see how much better with the V3 map. B)

Crazy out-of-the-blue question, does anyone know of anyone with first hand experience of megatunix?

I'm looking at getting an eeePC and getting Xandros to work fully, rather than the stripped out version it ships with. I've had a quick look on msefi but there's only one post with any useful info in.

I think Rog was running it for a bit through Windows. It's not so much MegaTunix I'd be interested in as MegaLogViewer or TuneStudio, those hold the real power. If you can't run MLVV on it I wouldn't bother, Novatech have Windows laptops from £280 which would be a better bet.

£160 Vs £280 is a big jump for me.

Tunestudio? search isn't bringing anything on that up on MSefi.

Well there's plenty of Itronix IX250's on eBay for under £100, or more normal laptops (anything from Windows 95 on a Pentium 2/300 upwards will run) can be had for £50 or less.

TuneStudio is what Nige is Beta testing at the mo, so not really for general consumption just yet but it's looking brilliant so it would be a shame to miss out.

I confess, part of me just wants to fiddle with linux on an eeePC - I know there are easier/cheaper ways of doing the same thing.

MLV has a Linux release, by the looks of things.

If TunerStudio is the same as TuneStudio, that looks to have a linux release too

megatunix is good. I run it sometimes on my windows machine (took about 6 hours to download all the extra SW so I wouldn't recommend this if you are not geeky). Lot better than MT in some areas.

Tunerstudio is Java which should make it cross platform (snigger). In theory, you could stick the application and all you maps onto a USB stick so you could swap to a different laptop in seconds (provided it had Java on it). For Rolling road tuning this offers a great leap forwards. I played with an early version of tunerstudio and it ticks all the boxes for dealing with the reasons why so many 'professional' tuners say that they do not like MS.

Yes, still do, tend to revert to Megatune when "in the field" but for workshop or pure pose factor* I use Megatunix.

Megatunix is very good, a little more compact on the GUI which can make it a little easier to click the wrong button if you get my meaning.

The tooth log counter is a nice little touch, graphically satisfies.

But its never failed me or crashed, so would not hesitate in recommending others to at least have a try.

*Pose Factor = If you can be bothered, you can make some really "trick" looking dials, sadly, Ive killed the toughbook, so no posing at the moment.

Not sure what went wrong for you there Bill, I would have said the extra software took about 10mins to sort out.

the cygwin install I have as part of the MS dev environment was fighting with it and the version of one of the libraries didn't work first time, or second time or 3rd time. and I have a slow internet connection and a very old and slow computer. In the end had to completely reinstall everything.

For anyone interested in running megatunix and not wanting to download all of the cr*p involved to compile the source code to run it on windows......

If you fancy a learning curve, download ubuntu linux and burn it to CD then visit

http://www.pendrivelinux.com/2008/05/08/us...stall-tutorial/

This will explain how to make a USB persistent installation of ubuntu linux to one of those USB sticks, 1GB will work but a 4GB one is better.

Ok so why bother with the USB persistent part.... Obviously you want to keep windows and just boot into linux and not change your windows installation.

Now you need to install megatunix onto it. and to do this follow the tutorial at

http://www.msextra.com/viewtopic.php?p=151941

Watch linux do lots of code carp things like the matrix and then your done.

The most obvious benerfit of doing this with a USB bootable version of linux is you can carry that USB stick anywhere with you, which will include all of your tuning software. All you have to do is find someone with a lappy capable of booting from USB if your up the creek without your lappy.

Thanks for the info guys. It'll be a while 'till i get any MS-related software on an eeePC, I'm just about to buy one for another reason, but I wanted to do the ground-work first.

Getting a JRE set up on Linux can't be that hard, though i've never done it before.

Linux can be an absolute pig at times, Im not sure if the eeepc can boot from a USB port but if it can it might be woth trying the above. I think the linux operating system that the eeepc comes with is a cut down version of debian / ubuntu linux. Cut down versions can be difficult to complie soure code on.

I will find out if the eeepc is capable of booting USB, if you have to go down that route because it fails to compile the source code in eeepc linux

Possibly slightly offtopic.... but here goes...!

If I megasquirted my v8, would I need to megajolt it as well to wreek more of the benefits of the systems available?

Also am I right in thinking that the megajolt element manages the spark and would effectively enable the motor to be run (reasonably) fully submerged as is will be in a challenge motor?

Therefore also out of interest.... how was mouse made to run fully submerged?

Not off topic at all,

The Megasquirt ECU running MSnS extra code can control fuel and spark, by far the most common is ford EDIS.

The Megajolt ECU will control spark only.

If you are going to megasquirt yours then there will be no need to fit megajolt as well because megasquirt is fuel and spark combined into one box when running Mega Squirt n Spark extra firmware (this is the software that the ECU runs) And yes EDIS apparently waterproof but iv yet to fit mine and go find out lol :P

This is in the tech archive :P but Aaron is correct - MegaSquirt can run both fuel & ignition. MegaJolt is ignition only.

would effectively enable the motor to be run (reasonably) fully submerged as is will be in a challenge motor?

Running EDIS (via MegaSquirt) does remove the weakness of the distributor, and assuming the rest of the car can cope with it will run happily underwater. Ask Boothy or Rog how well it works :P

Therefore also out of interest.... how was mouse made to run fully submerged?

Mouse isn't MegaSquirted, the LS1 ECU is pretty good as standard and runs coil-on-plug already. Reflashed ones are cheap enough that it's marginal.

Hi All,

Love the recent input,

but if OK with all I will let this go on for a while, then a bit later you'll see its gone as I

will move the "Linux Megatunix" stuff across to the 'advanced MS' thread shortly as I think it is more suited there,

I will leave a linky on this thread saying "If you want Linux info see this other thread"

Linux / Megatunix is def advance IT skills and the software / learning curve is very different to MLV / MT etc,

and we don't wnat to spook the newbies do we :lol: ?

:)

Err, I understood "Hi All" Then you lost me! :D

Right, whats the best thing to get started with?I could do with as simple and as user (User is an IT idiot) friendly as possible to start with. Theres going to be quite a lot of work going on with the truck so id like to be able to get it up and running as easily as possible as I fear there will be a few issues to deal with.

Also does anyone have a MAP that might work half decent with a std 4.2 as a starting point? Or one I can just plug in and forget for the near future while I sort everything else would be brilliant! Then as I get the rest of the build to a usable stage I could look into perfecting the Mapping a bit more.

Cheers. Steve.

Absolutely Steve

This MS thread is designed to allow a newbie to MS to see what I and others have done, learn the basics and get enough confidenece to maybe then take the plunge.

Whilst the Linux / Megatunix is valid and valuable info / options it could easily IMHO make a new looker at MS run off into the sunset screaming "Give me a Stromberg quick :lol:"

As such and for this reason the Advanced MS thread was started and is a repository for more advnaced options that users of MS may wish to take on board once they have an understanding of the basics, hence my comment re all the above, I wuill prob wait to the weekend than have a tidy up, its valubale info and worthy of this forum, just maybe better in a differing thread.

This thread was designed to help people like me (electrical IT Idiot) to get a working MS on there V8

this sums up my IT skills and the above thoughts nicely ?

I think it's possible with the table switching option to have an "empty" fuel table, the other option is that the table switching switch also shuts down the power feed to the injectors.

Ok heres the plan.. I have duel tables so I will, as you mentioned, use an "empty" fuel table but when i switch tables it will turn the fuel pump off and power the gas system.. injectors idle but powered and what sort of adv. on my "standard" fuel map. Back in the dark ages.. the dizzy was run about 12 deg adv on gas ( roughly as it used to jumall over the place). :blink:

Just to bring this full circle, I now have TunerStudio working on an eeePC. Shame i can't do anything with it, as i don't even have a megasquirt yet! oh well, in time :)

Update! HFH tuneing services has made my 84 RR run like a dream.. B) we are on V.8.1 of the maps and are working to iron out the fine tuning rough edges. Also with the duel tables ive set the 2nd spark table 2deg adv over the petrol map and it runs very nice and the VE 3 table just blank. When the gas is switched on the fuel pump is switched off. Another bennefit it the MPG has gone UP! even with the datalogging and giving the right peddle a good shove its better than before MS. Ive got an event this weekend so this will be the test and im expecting only good things from the car. BTW im sure HFH will point out what an oddball motor ive got... :rolleyes:
