hi, i'm new to the forum and to efi on minis. i know the basics but am a little overwhelmed by all the options. basically i want to drag my N/A 1380 into the 21st century by putting efi and mappable ignition on it. I've seen the omex kit offered by minispeed but the price puts me off. i've heard of megasquirt ect and wondered how difficult it would be to build my own set-up. the mechanical side of things is not a problem, i am a design engineer and can build my own manifolds, tbs etc although i know nothing about maps, injectors, ecus ect. what i need to know is what bits i need and where from? i'm also aware of the siamised port problem so an spi set-up would be easiest? what are my options and what would you reccomend? |

i was thinking about using a k series TB on modified hif44 style manifold with an injector in a spacer between the TB and manifold. all controlled by MS (fuel and spark) would this work and how do i sort out the mapping etc?

i may be tempted to wait for your mpi code I think you mean JEAN'S MPi code.... He is the man who has done all the work on it.

i havent looked at the inj thing closely ,but is there a reason why one cannot simply stick 4 injectors in where the su was and a throttle valve and map that ? i would have thought that with the heat of the manifold ,a wet system like that would not really behave v differently to a inj close to the head coded to avoid mal distribution , in fact ,the greater weight of air plus fuel would create more inertia and more ram tuning .so may even prove superior in bhp terms to dry inj .... Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM |

No I'm from Split, it is the city on the sea, but I've been in Zagreb with my mini couple of times. There are not a lot of Minis in Croatia, that is true, and I know most of the owners, including the owners from Zagreb, and I don't know any owner of green Mini faster than rover 1.3i in Zagreb. In 1997 I was 18 and I've put first turbo engine in my mini when I was 19 so that couldn't be me. Those same cars that you are talking about were probably Yugos, our yugoslavian heritage. regards, Tonci On 17th Nov, 2014 Tom Fenton said:

Why would you need four little injectors?? one or two decnt big ones will do the job just fine Going back to an old topic I read just the other day, VMax supercharger kit only uses two MJY100460 injectors, one is used all the time the second is staged. This is easily achieveable with VEMS, the staging code is already there and no extra hardware is required. Id expect Megasquirt to be much the same, though i havent looked at it.

Is it A-Series only? I think it should be... So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'... On 26th Oct, 2004 Tom Fenton said:
Yep I agree with TD........ |

megasquirt forums are also a good read, along with the mega manual, a little overwhelmign at first but once you start digging it all become clearer :)

i like the idea of the mpi set-up. i'm gonna draw up a manifold etc, what TBs might be suitable (around 40mm dia)? if i get all the hardware sorted for both spi and mpi set-ups i can get it running on spi then swap over to test some mpi codes if anyone has any they want testing? |
