I'm hoping someone on the forum can help me - I'm sure I've seen in one of the club magazine, or read on the forum that someone is running the Specialist Components fuel injection system.
Is this correct, or have I made this up in my mind?
I ask as, after negotiating with my missus (it is pretty darned expensive) that this could look to cure the MM's running problem. But before committing to this I'm trying to work out if this system will fit in the MM engine bay without modifying the bulkhead.
https://www.specialist-compone.....rottle-body-kit.html
The (possible) issue being this system uses a horizontally mounted throttle body, the standard MPi being vertical on top of the inlet manifold.
I also need to consider that the bonnet sits closer to the engine than on a mini (I can't fit the standard MPi airbox on top of the TB). I'd be happier having to modify the bonnet to accommodate a deeper inlet set up, than to try and fit a bulkhead box (as when running a Weber).
I've got in touch with SC and asked them to provide dimensional information so hopefully I can measure up, but there's no substitute for experience. So anyone who does have experience of this system I'd appreciate tapping in to your knowledge.
Thank you.

What about using megasquirt or similar to run on your existing set up. I know very little about it but I do know megasquirt is used on lots of rover V8s.

Mike,
I've heard of megasquirt on the Turbominis forum. But I believe you have to construct this unit and while I think I am going to have to try and learn all about this programmable ECU lark, I think that might be a bit beyond me. The SC system being a bit more plug and play.
What price convenience? (About £1800 apparently)
One other small thing - the SC system continues to work with the Rover immobiliser and alarm. Not a reason on it's own to select this unit, but I do know the IVA requires an alarm/mobiliser.
But if you have any experience of the megasquirt and can tell me it's not as daunting as I think it might be, I'm prepared to be convinced. |

Megasquirt-V8 is a friend of mine his main thing is rover v8 but he's a nice guy so have a chat. You don't need an alarm/ immobiliser for IVA mine just went with door, ignition and steering locks.

John, thanks for the link. It does look to be cheaper (half the price, if not more) but, if I'm being honest, still a little scary.
Mike - Megasquirt-V8 is who, and how do I contact him for a chat? |

Nigel Barker at https://www.megasquirt-v8.co.uk/ms_what_is_ms.php
If you mention me at all you may need to remind him I had a tomcat and now an ibex.
Might also be worth a look at lr4x4 forum there is a section in tools purely for megasquirt.

It's a steep learning curve. I built my own efi system, including all the hardware, from scratch for my VW Beetle engined UVA but, having done it once I wouldn't hesitate to do it again.

Just spoken to a mate that understands megasquirt. He's said the best person to talk to is Shaun O'Donnell

Thanks Mike - I'll call tomorrow. I dropped Nigel Barker a line last week too. Waiting for a response.
I mocked up the inlet manifold and carb that came with the car way back when this weekend, to take some measurements. From the info (drawing of measurements) SC sent me I think their system would fit although I wasn't able to get to the car this weekend to confirm.
If I can get some info regarding the megasquirt and using it with the current set up I can make an informed decision which way to go. |

According to my friend megasquirt 2 would be best suited and should work with existing sensors etc once set up. How much work and grief it is though I don't know.

The thing about the Megasquirt is that there is a massive amount of information out there from users and builders and their responses are practically instant
The Megasquirt 2 would definitely do the job.. |

John - I've reached out to Shaun, as suggested by Mike. He hasn't done anything with an A-Series before, but doesn't see it as being too difficult.
I've sent over information I've gathered over the years regarding the MPI system as developed by Rover (Mike Theaker) and an 'electronic library', which provides further details of the FI system and the sensors which the MPi cars/loom has as standard.
Shaun is also able to supply looms as well as MS2 building, so hopefully a simple engine loom swap (if needed).
I've said I'll call him back next week to discuss further if he's able to help.
And as you say, there does look to be a lot of knowledge out there regarding Megasquirt (I'm aware of it via the Turbominis forum where it seems to be used a lot and is widely discussed), so hopefully the software is well know if the car needs to be set up on a rolling road.
Hopefully this could be the more cost effective solution!

I've received a reply from Shaun. He needs some more info and had a few questions that I'm going to call him back this week and try and answer.
The 'estimate' for cost for this solution would look to be around 2/3 the SC system at the moment (further info needed to provide an more definitive answer. So not as cheap as I'd first predicted, but a potential healthy saving none the less.
Reaching out on the other forum for some advice on using Megasquirt - how easy it is to use and if anyone else has got it on an MPi car, it was suggested that I look at using an Emerald ecu. A bit of research on this shows it's a product developed/sold by Dave Walker.
I've enjoyed reading articles written by Dave Walker for many years, first coming across him in Cars & Car Conversions.
One of the articles on his website refers to fitting FI to a midget A-Series car:
http://www.emeraldm3d.com/articles/cat/projects/post/midget_Project/
Reading this he comes to the same conclusion I think as SC, in so much as it isn't really possible to efficiently port inject the A-Series because of the siamese ports, better to run an 'electronic carb' wet manifold solution as efficiently as possible.
I believe the MPi mini ran the biggest standard Rover injectors available to try and get sufficient fuel into the engine so potentially there's a limitation here?
I'll give Shaun a call as I say. It may be possible to run the standard set up with Megasquirt with more control to optimise the standard set up.
