megasquirt maps
Hi Guys
Got a few questions about megasquirt and spark...
Just spoken to a tuning chap, and he was asking if I had a cam position sensor and knock sensor wired up to my megasquirt? I know it supports knock
sensing, but has no wire coming from the ECU itself.
My question is do I need these functions, as he seemed to think they were important for the running of the engine.
I'm finding learning megasquirt pretty hard going, but i think im getting there slowly. The engine is having heating trouble, And im hoping this
is down to the fuelling and mapping of the engine.
Im running a 2.0 zetec with gsxr600 TB's, and am looking for a map that someone has already for theirs, to see if it helps me understand a few
things.
If someone could email me their MS file, I'd be very grateful.
Another thing, I havent wired up the TPS yet, its a standard 3-pin one on the GSXr600 TB's and not sure which pin goes to which wire on the
MS.
Can't wait to get this thing up and running properly!
Many thanks guys
Tom

Also have your injectors/or mega squirt been modified to suit??

I've a 1.8 Zetec with Jenvey TBs. The cam sensor isn't wired up, and I don't have a knock sensor and it runs fine. Send me a PM if
you need a map or help. There are a couple of 1.8 and two litre maps doing the rounds, but I didn't get the engine running better than it
already was.
Things you need to do before turning the key. These are in the general settings page:
Injectors: Make sure you know the flow rate, and whether they're high or low imedence. I blew the flyback circuit on my squirt because it was
set for high impedence and they were low impedence injectors. Read the 'Setting The Constants' page for more info:
http://www.megamanual.com/v22manual/mtune.htm#constants
Set the required fuel based on your injectors. Look at this table if you need help: http://users.erols.com/srweiss/tableifc.htm
Are you running just the TPS or have you got a MAP sensor? If it's TPS you need to change the control algorithm to Alpha N, and change the
configurator setting to the same (I can point you in the right direction if you need it, I don't have the correct laptop with me). I have been
advised to change to speed density, which I'll be doing soon.
Configure your TPS using the relevent menu option.
Megatune can generate a map based on your engine output but the results aren't fantastic, but it should get you running.
Let us know how you get on.
Mike

On my gsxr1000 bodies black is earth, blue is +5v and yellow is TPS signal 
Knock sensors aren't required, they're just handy if something goes wrong. If you're a bit conservative when you map your spark
tables then it'll be fine, this is what manufacturers did for 80-odd years before knock sensors came along. Very few MS installs use a knock
sensor (mine included) and i've yet to hear of a dead engine because of it.
As for cam position, you don't need this unless you intend to run coil on plug ignition. On a zetec the most starightforward is to stay with the
wasted spark coil pack, which just requires a signal from the toothed crank position sensor wheel.

Oh, and the engine running hot could be because it's slighly lean, or the ignition is retarded. I'd get the TPS wired up asap,
you'll really struggle to get any kind of tune done for low/mid throttle using MAP as the load input on bike tb's, trust me, i've
just tried

Megasquirt Map
I have a 2 ltr Zetec with GSXR 750 throttle bodies. I have bought a Megasquirt 1 V3 with MSnS and was wondering if anybody has a map they can send
me

Guys,
As there's been a few requests for maps, I've added a page of Zetec megasquirt maps on my website. You'll find it over at
http://www.classicfords.net
Cheers

Just to let you all know, we did run MegasquirtMaps a few years ago, anyway the domain has elapsed, though I have created
www.mtechmaps.com
I'll keep adding maps over the next few days as we obviously have hundreds on file. Any special requests post in the requests forum under your
ECU type and I will see what I can find in the archives, or make you a 'best guess' starting map. Cheers
Matt
