megasquirt 1 v3


Recommended Posts

Hi Everyone,

 

I was priced of the road in my vr6 three years ago due to high insurence but now I can afford to put my toy back on the road!  finally been 25, i swapped the vr6 in about 5 years ago and i couldnt let her go, i just loved the car far to much.

 

I allways had the problem where my car would never scan on VagCom so iv giving up with the standed ecu and got hold of a megasquirt 1 V3, i plan on keeping it as megasquirt 1 as i cant see any need for the incressed fuel tables for my needs.

 

I hope to find the time this weekend to start installing megasquirt into my car, I plan on using all of the standed sensors this includes the narrorband lamba sensor and getting a wideband if i ever get round to forced induction.

 

theres a few questions I want to ask as im aware a few people have done the swap.

 

has anyone manged to use all the standed sensors?

is there anyone still running megasquirt on there vr6's?

will i need to change my coil pack or can i use the standed coildpack signaling through ICM?

 

and is they anything i should be extra careful about not to damege my megasquirt?

 

hopefully my unit should arrive on wednesday so i should be able to check the setup and have a look into how its been built all i know is it was built  by a company called M-tech automotive and is ment to be set up for a turboed vr6 so im allready aware its going to need some software changes.

 

thing you will want to know,

 

12v 2.8 vr6

obd2 is the current setup

and im not scared of wireing

 

thanks in adavnce for any help.

Lots of people are using lugatrionic these days, as it's all plug and play and will work with all standard sensors.

Mega squirt is quite afew years old now.

I have limited knowledge of mega squirt but from what I have, it can only work up to certain knock count. So can't be used on new 24v or r32. Or any car with variable valve timing. Why lugatrionic took over, plus it was designed purely for VW and Audi and to work with VW and Audi sensors.

Ah your not inspiring my confidence here :P I'm only ruining it on a 12v so it shouldn't cause to much problems there i got to say megasquirt is a fair bit cheaper which is why I'm going down that road, looking at it I think I'm already going to have to modify it for extra spark just going to have to work out how.

Why are you using Megasquirt? The OEM ecu is far better and there are full def free files available on the net - some tuners seem to be using them.

I want to go forced induction eventually and I want to get most of my parts from the scrappy which mega squirt is fairly good at accommodating and I just want to teach my self something new Tbh, my golf is a learning tool for me and not my daily.

God I'm good to you lot aren't I!

 

Get the free winOLS, get this file I put up here and you have a full VR6 turbo file to learn on! Convert it from German to English and it is by far and away the quickest way to teach yourself about your ecu!

Sorry to dig this from the grave had alot pop up in life and had to put the golf at the back of the list, any chance you could let me know more about this?

It's the ecu from a Motronic 3.8 VR6 12V for use in winols (demo) or to make your own tune file xdf in Tunerpro. These files can be found online or in packs you can buy, but I would never trust anything other than making my own. It has LDR (boost control) maps in it so it looks like a turbo file but I have never used it nor looked into the validity of how such data has been added to the binary. 

You can make a fairly basic map pack from it to tune your own similar ecu though even if it's naturally aspirated - i.e. looking at the more major ignition/injection maps for example and make an xdf file from the maps data that comes up in winols demo.

They're all MAF based so you have to compensate a fair bit, MS/MAP sensor likely far easier for you tbh, you could practice on that and/or below though I suppose or even do some tweaks on oem NA set up dep on if/how easy people can flash them..the later ones can be done easier over OBD with some tools than early ones (M2/3 evolved on the 12V before ME7 so not sure of which codes/tools mix but some info on Nefmoto etc and look at those who do things like the AGU engines on old M3 systems like the link). Ecuconnections do a fair bit with the older Motronic systems too.

 

Just another option there for people to tune them that's all. Can take years to do a good Motronic NA to FI tune though, even Motronic specialists often request tunes for these things if they don't have plenty of time or buy what's available through their tools/re-seller tune files.
