M/S - How long did it take you?!

[Jhonno]

As title really.. For all those that have installed M/S how long did it take you to from the beginning to install and get it running/driveable

[e30_Turbo]

First time, a few hours on the install, finding places for sensors, working out what wires could be used or which needed a new loom. Once the sensors are working and you can see the ECU working you start to connect with it more.

There's enough info now to do a super-sleeper install using all the stock loom and just changing where some of the ends go, the moronic ecu case opened up with a ms inside and cross wired is the way forward for sure.

As for tuning etc, I've got maps, so has Ant and on e30tech there's many to try, all basemaps like, will still need to be tweaked.

Once you get it installed and running properly you're away, they can be very twitchy and need good earths and connections to run spot on, little things can be a PITA but once it's working well it's more than worth any hassle.

I'm sure Ants got a plug N play setup for MS now anyway.....pretty sure he said he has his source sorted

Go on join in, you now you wanna!

NO MORE AFM WRONGNESS!!!

[Jhonno]

Its not for me.. Its for my housemate.. He has all his M/S stuff in the post on the way this week

It is being installed into the Moronic case

Would be needing maps for an M20B25, tho it might be a 2.7 conversion..

No worries, tweak tweak, sorted

You'll have a base map on the chip, usually a V8 one but weirdly enough Toby's 3.5 ran on it out of the box! The basic settings are pasted all over the net and I'l happily share a MSQ file which has it all on anyway, you'll just need to check it all before you turn the key.

I'm thinking Oguz is a 2.7 N/a on Ms.......

Has you're house mate got a spec in mind? Stock ignition or wasted? I suppose Alpha N stylee will be preferred.

My MS is modded for more toys so some of my settings are not quite right for other setups, still nothing that can't be changed.

[e30_Turbo]

Prepare to spend hours staring at these!

[Jhonno]

its going to be wasted spark using a vectra coil pack. Whats Alpha N stylee? afm is being dropped

IAT, TPS being run, also have a wide band

we dont know much about the lump, other than told its a 2.7, it is as quick as a T5 rolling and off the lights as is..

Alpha N or Map sensor, MAP reads the pressure on boosted lumps and Alpha N is mapped against TPS IIRC. Just the two ways of using MS to do the same thing a different way.

Wasted is a really good mod, is a fecker to set up though, however you could be lucky, fingers crossed.

WB is also an excellent idea, another safe investment, just be careful with it as they're very sensitive and I'm on my third sensor and second whole unit.

If it's a monster already then from what Mattg saw on his N/a lump you'll be looking at 10-12% power increase and upto 18% on the torques!

Plus the induction noise ow and most of all the sharp crisp response!

Ant fitted my MS, wasted spark, M30 injectors and mapped the car in day.
Would have been quicker but there was a bit of experimenting with various bits bobs.

Someone on here (was it flappysocks?) did a really interesting article about MS on Wikipedia or something but I can't find it.

People talk about learning lots about it - then installing it, with the reading talking the most time. I like driving MS equipped cars as they are so sprightly.

I must say i am very happy with the set up, Ant did a fantastic job and every time its had a tweek it has been getting better and better to drive.

Id loved to have done this myself, but i have neither the time, understanding or patience needed for such an install and mapping.

Sound good! Whats the difficult bit about the wasted spark? How do you go about trying to avoid breaking the wideband?

Be nice to see some figures like that off this thing, it goes well as is, noise is a good thing also

There was more to it than that link though...

Try it again, his server went down.

[FlappySocks]

The fan in my PSU stopped spinning, and cooked the PSU. The site is back up now. I will have details of my new PCB soon, which arrived from the US today. Provides 3-wire ICV output, Tach, shift lights, and two auxiliary outputs. Just need to find the time to test one.

Great stuff! Bookmarked!

[Jhonno]

anyone got maps for a 2.5 and a 2.7?

anyone got maps for a 2.5 and a 2.7?

Only on old versions of the firmware!

Not sure I have a 2.7 one though....

When this next map is done I'll have a fresh map on 029y4.

Seems the old maps don't work on the new software, more mapping required!

WB is also an excellent idea, another safe investment, just be careful with it as they're very sensitive and I'm on my third sensor and second whole unit.

What specifically damages them, and is it wise to leave it in place once set up or remove it for safe keeping?

Cheers,

Too much heat, water, oil, banging it about, basically they are quite sensitive and be real careful when wiring it up as any wrong feed will kill it. My first last 18 months plus and only shat itself when I blew 4,5 & 6 out and shoved some lovely mayo up the downpipe!

Placement is key as is angle, keep them in between 10 and 2 and no less than 6 inchs from the turbo exit, mines about 6 inches away and works fine.

The wire that carries the signal from the sensor to the box is also a potential issue, I've had problems with that wire hitting the strubrace and causing weird readings, tieing it down sorted that out but I was surprised it had such an effect.

They're good usefull bits of kit but just be aware they're not indestructable.

HTH, Mark.

Ant should have a map for my 2.7 Jhonno. You are welcome to it

[Jhonno]

Ooo.. How would i go bout getting it off Ant? Could be handy as if this is a 2.7 it would be similar spec to yours i think..

Dont know really I'm sure he will though Give him a buzz
I think its quite a conservative map aswell as my 2.7 didnt like too much timing advance.

[Jhonno]

Turns out the USB to serial ports driver doesnt like Vista..

[scotty86d]

Yes heard about that issue a while ago.

[pilt]

Anyway, back to the main question - How long did M / S take?

Well not long in my case!

Basically I followed the great guide put up on http://www.diyefi.co.uk/ by FloppySocks on here and it only took me a few hours to get it running!

I followed his guide and wired the megasquirt connector to a motronic connetor from a old broken ECU I had which took a couple of hours at work. As a test I put the ECU in the car in the foot well hanging by its wires to see if it would power up and talk to the PC correctly. To my suprise when I turned the ignition the fuel pump wurred into life and showed MS was doing something! (I assembled the M/S from scratch and have no stimulator so wasnt sure if any of it would work!)

Anyway I started buzzing out the wiring to check it is if was correct but after buzzing out the coil (first thing i had checked) I was getting impatient and thought I would see what would happen when I turned the key........

At this point I had loaded in the .msq configuration I got from FloppySocks off his website and to my shock the engine burst into life as if it was still on the old motronic, except was running super rich! OK i then realized I had forgot to hook up the vacum hose and my inlet temp sensor was reading -40C but she was running and this is on a cold engine that hadent run for a week! Putting in the vacum hose and temp sensor (in the footwell....) soon sorted out the richness and she was running smooth as if not better then motronic! Idle is a bit high at the moment at 1200 rpm but this is becasue I haven got the idle control sorted.

But anyway many thanks to floppysocks who made the whole install a heck of a lot simpler! Now i just need to fit the turbo and get tuning........

Great work Dan Thanks for the complements... Welcome to the MS club Got any pictures?

I remember when I first turned the key. I swear I saw smoke coming from my coil driver wires, and shut it off quick. I must have been a bit too paranoid, as I couldn't find anything wrong. When I went for the second attempt, the engine fired right up. That was only a year ago... the megasquirt community has grown so much since then.
