Jessopia74 Posted October 17, 2019 Share Posted October 17, 2019 (edited) I think this deserved its own project thread. Plenty of chat about Megasquirt in various threads, but nothing conclusive is ever posted, so thought it would be good to post it as it’s own project. The addition reason for this is I have not yet decided what power plant or which of my cars will actually run the system as yet. The more I have read, the more I am impressed by its capabilities. My intention: I won’t be writing a dummies guide, but will take the thread through my journey front start to finish listing everything I purchased, what reference material I used, specifications and so on. I will at time link to other guides written by others if I found them of help on my journey. Anyway, let me introduce you to my choice. I have opted to buy a ready built unit and arguably from one of the best suppliers. The chaps over at ExtraEFI are pretty helpful too. Let’s be honest, with a project like this, support is everything! My choice has been MS2 with extra code. As it will do everything I want it to do. Controlling fuel and ignition with a built in manifold pressure sensor. PHIL @ ExtraEFI helped write the ‘extra code’ and the site is often referenced for the help sections. Before purchase we had exchanged a number of emails, with my plans of engine (Xe at the time) and ignition coil to use. A later VAG 2coil (oem part number 032905106B) is what Phil recommended as it has built in drivers putting less extra circuits into the MS2. So this is what I have so far; Megasquirt2 with extra code, for VR crank sensor and tacho output. Comes with short loom, Rs232 cable and disc of guides etc. http://www.extraefi.co.uk V-Top USB to serial adapter. Purchased from Amazon. My laptop with Win10 recognised it right away and auto configured. https://www.amazon.co.uk/gp/product/B01LVYR1AB/ I already had the following items, that would be required for bench running. 12v switching PSU , MULTIMETER, basic electricians tools. A MUST READ TO START http://www.extraefi.co.uk/support/Confused.html https://www.migweb.co.uk/forums/engines-transmission/383877-how-megasquirt-vauxhall-engine-ms2-v3.html helpful guide a user on MIG wrote, based on MS2 v3 👍 Next immediate steps: install the Tuner Studio software on laptop. ( http://www.msextra.com/downloads/) or (http://tunerstudio.com/index.php/downloads) Bench power up the MS2 and make connection.

Shug Posted October 17, 2019 Share Posted October 17, 2019 I have a megasquirt from extraefi running the 2.2 in my A series. Running injection only as using the stamdard ignition module with cih dist. Clearly idiotproof as I got it up and running myself 🤣 2 Quote Link to comment Share on other sites More sharing options...

I know we have people out there with it 👍Did you have rolling road tuned? If so it might be really useful to others if you can share your map file into the thread.

Jessopia74 Posted October 17, 2019 Author Share Posted October 17, 2019 Well bench setup is good. Tuner Studio found connection without any trouble at all. Obviously I have no sensors connected as yet, will start to add some over weekend. Project images are available to Club Members Only, Click to become an OMOC Member.

Have a lambda sensor attached so ran auto tune then fiddled a little with it myself. Needs proper tuner to have a go as its great up to about 3.5-4k rpm then drops off. Not many about up here, much less ones with megasquirt experience. Quote Link to comment Share on other sites More sharing options...

611 Posted October 17, 2019 Share Posted October 17, 2019 Looking good and as you say good to have some info for others who are thinking of running it. Got my Omex and will be writing that up on my blog in case anyone is interested in that system. Andy 2 1 Quote Link to comment Share on other sites More sharing options...

611 Posted October 18, 2019 Share Posted October 18, 2019 Always hard to know what to go for when there is not that much info out there. Lots for other cars but all a little scarce for the old Opels 🙂 Quote Link to comment Share on other sites More sharing options...
Jan Posted December 4, 2019 Share Posted December 4, 2019 (edited) Greetings from the Netherlands. In the first half of 2019 I installed a Megasquirt clone in my Manta A 2.2E. Did everything myself including the tuning. https://opel-forum.nl/forums/topic/2-2e-cih-met-efi/ In the above link you can see some pictures, sorry for the Dutch but google translate is your friend.

Jessopia74 Posted December 5, 2019 Author Share Posted December 5, 2019 Yeah, thanks for the link! as for my project, been collecting sensors and also picked up a timing wheel from eBay, so will be ready to connect up on test bench shortly. What is really odd is the lack of shares of maps 🤯 Quote Link to comment Share on other sites More sharing options...
Shug Posted December 5, 2019 Share Posted December 5, 2019 (edited) I'd share mine, but its pretty much the autogenerated one which you'd get running the generator in tunerstudio. I'd be interested in seeing other 2.2 maps to see how they compare with a default one. Just clocked the laptop. Had similar when I put megasquirt in. It died on me so couldn't get map until I get new laptop up to where I left the car. (Getting resprayed) The car that is, not the laptop....

I have a standard camshaft and standard injectors. The standard 2.2E cam is the mildest there is for Opel CIH. It gives low rev torque and doesn't like RPM's over 5000 So if you like increase in power on your 2.2E first put another camshaft before buying an expensive EFI. Mu car is abit more powerfull with the EFI, probably because the Le2-jetronic airsensor is gone, this a big restriction. The intake manifold is also small for good airflow on a 2.2E . So the car is good for touring and nice driving. 2 Quote Link to comment Share on other sites More sharing options...

Yeah, thanks I was talking more in general rather than individuals. But it’s a good point, I do wonder how many users actually have a fully tuned map in their MS. 1 Quote Link to comment Share on other sites More sharing options...

Having previously read through many posts on this site realise that the 2.0 head, inlet valves & manifold are even poorer than the 2.2 but I’ve been quite interested in what the effects of a modern EFI would be on a standard engine hence the questions The air sensor issue is an interesting insight thank you Quote Link to comment Share on other sites More sharing options...
Jessopia74 Posted December 7, 2019 Author Share Posted December 7, 2019 I suspect it will release a decent amount of horses, but the main benefit will be the correct ignition and fuel through the whole rev range. So it’s likely to increase delivery more that top end BHP. On std Redtop engines that swap over, it usually results in a 20/25BHP increase, so it could potentially be around 20BHP over the Ljettronic setup is not out of the guesstimate realms. If you could throw some money at throttle bodies, it would out perform a twin Webber setup and we know what those can get Circa 140/150. 1 1 Quote Link to comment Share on other sites More sharing options...

Jessopia74 Posted July 19, 2020 Author Share Posted July 19, 2020 Yes, sort of. I have it set up on my bench, and managed to get a correct TPS, and calibrated . Temp bracket fabricated, and ordered some Alu stock that is correct thickness to make a nice conversion plate for TPS. Also a wideband Lambda and started playing with a timing wheel, slight wrong teeth for XE but it got pickup tested and me into startup map. (check out my pillar drill test rig lol) I snagged my Silver coupe on some paintwork bits I was not happy with at body shop so not had a base car to install, tbh they probably sick of it been there now as I was away with work etc. However, been collecting loads of other bits, sensors etc so I might be able to get on with the XE install and the injection conversion next week when I will have 4weeks off work 😁 So bench running was positive and think I am ready to go 🙈 Plan is to set it all up on std XE inlet manifold for now to get it running and then swap to ‘direct to head’ ITB’s after I gave it running.

You've got far more patience then me 🙂 It was enough work for me to swap over and wrap up the loom on mine for the Omex! Be good to see it when you have it all up and running.

Andy 👍 going to use a modded XE loom as starting point for startup, but when swap over will build one from scratch, just need a huge white board to pin and lay out all the wires 🤯 2 Quote Link to comment Share on other sites More sharing options...

I had a bare loom for my Omex and although they give you a diagram they are never totally helpful and im sure they like to leave it so there is a little bit of guess work needed 🙂 1 Quote Link to comment Share on other sites More sharing options...
