No build thread really, some info and photos here http://www.turbomini...tid=358245&fr=0

It's hard to say how much better it is, as it's all down to the mapping. In general it starts better and is more consistant in operation. After spending time getting it running right I just drove it for a while. I'm now tuning it to make it more economic. You can really run lots of advane at cruise and lean it right off. There is still a bit of a compromise to smootheness and economy, and as you learn your engine you can change the map to get it better and better.

The beauty of the SC ecu it the number of bins available to give really good resolution on the fuelling. It also hase some great featurers to optimise advance and fuelling.

It has a massive range of options in use because it will suit economy engines and full on race engines and there are 2 throttle body options 45mm and 50mm
It has two fuel injectors one working all the time and the 2nd comming into use when needed.
Im am looking for good fuel economy & max torque in the low to midrange power band because i have a small eriba puck caravan i some times tow to shows and events with my mini club.
I would opt for the 50mm option because it is more versatile it will still work well on a small engine but if you want to change its use at a later date and fit the same unit to a larger engine the 50mm wont hold it back.

This isn't correct. The injectors both run all the time. For this system to work they need to fire alternatly and 4 times per revolution.

Thanks for that not doubting what you say but i thought they told be the opposite
but to be honest as long as it works well who cares lol

looking forward to this build trend, keep up the progress and take loads of pics..

one question on the idle valve. if yo add one.. what controls it. i'l assuming it works by taking a signal from somewhere to maintain engine speed at idle.

so where does it take signal?

[mini13]

the ECU will controll it, it will open it depending on engine speed and or temperature.

[mini13]

also woth a look up the inlet to see both injectors spraying.

Swiftune cam arrived wednesday super quick arrived the day after placing the order and i had a phone call to say my gearbox is ready to be picked up
Thursday Engine company called to say crank needs a grind to -20 with new big end and main bearings bores ok just need a deglaze hone & new rings & also could do with new cam bearings
Sunday going to Bingley Hall to try & help the Robin Hood Mini Club win the best club stand comp & pick up a few bits and bobs ie cables hoses etc
Monday i will be dropping off the cam so they can fit and ream out the new cam bearings to match the cam then on to pick up my gear box.

is the wideband lambda part of the kit or do you have to add it seperately.
i'm assuming, correct me if i'm wrong, you have the lambda in the Y piece of the exhaust.

also again is there provision for this in the Aftermarket ecu. as the kit on SC site doesn't mention anything about fitting a lambda sensor in the installation instructions.

sorry for all the questions

[Wil_h]

It's not part of the kit. They are available off ebay for arond £150 to £200

I have a turbo, so no Y-piece. But my sensor is fitted in that area, yes.

Yes you wil lbe able to connect a lambda to the ECU. Check with SC, I think it's included in the standard loom, but ask for it to be included if not.

[danny79]

ok cool sound like a plan.

i'd initially planned to go the megajolt route but this is looking to tick all the right boxes better for me.

time to have a yard sale and sell off my bits and pieces and free up some cash for this kit.
hopefully i'll be running it in a couple of months.

one more question.. there always is..

the differance in the 45mm and the 50mm trottle body ???
is this engine specific. as initially this kit will be fitted to a 998 and when i have other engine built (1275 or greater) transplanted to that.
will the 50mm one run corectly on the 998 or vice verso would the 45mm work on the 1275cc.....

thanks for all the info.

now get on with the project, mad to see how it turns out

[Wil_h]

I'd speak to John at SC about what he would advise regarding the TB size. I use the 50mm one on mu 998 turbo, but that was more about intercooling pipe size than anything else.

What you will lose with the larger TB on the 998 (low down torque) you will gain in top end power on the 1275. Still 50mm is quite big, so if you are only looking for a 90bhp 1275 then I reckon the 45mm will be more than upto the job. It as big a a HIF44.

Their is a connection for a lambada built into the wiring loom and yes im going to fit it to the connection next to the y piece

I had a fantastic day at Bingley Hall
Bought quite a few things some
fancy looking gold spark plugs
9 stud head bolt kit
Alloy Rocker Cover with red wing bolts and red filler cap
New old stock Mk2 rear lights (Sons Birthday present)
Hand brake cable + clevis pins
spare water pump for sons car (bypass)
Rocker pillar spacers
Mini Hoddie x 2 one for me one for son

We won the best club stand which ended the day on a fantastic high

On a slight negertive i broke down on the way home the car just cut out like either the coil had gone or it had run out of petrol
The new plugs came in handy as we just popped one in a ht lead to see if there was a spark which their was so it looked like a fuel issue
The problem came apparent when i removed the filler cap to be greeted with the biggest gasp/rush of air it
looks like the breather blocked so we left the cap off put some tape over the filler and put a small hole in the tape and drove home ok..

i will post a few pics of my bits i bought

Tuesday after work i Picked up my fully rebuilt gearbox, looks great & 6 months garantee for £250
Wednesday dropped of the cam at Mansfield Engines (local company) they said the engine will be ready next wednesday.

Very interesting this. I've had a programmable MMS (K-DFi/MegaSquirt) in my Citroën AX so this seems familiar in some ways.
I'm starting the restauration of a 1980 Mini Van and quietly looking for a system like this (or CANEMS) for the engine in that car.
However, because wideband-lambda isn't used as standard here, I'm curious about whether this system is versatile enough to also solve the problem of the outer 2 cilinders not getting enough fuel and the inner 2 getting too much at higher revs.
That is a problem i've seen being described when people tried this kind of setup whilst running seperate wb-lambda sensors on the outer and inner cilinders.

Anyway, thanks for this topic! Will probably e-mail SC for more info, the price is a bargain actually.
