Hi all,

 

I'm new to this forum and found it while trying to find out which ECU might be used in my SPI.

 

My current ECU is the MNE101150. It is a coded one but the mobilizer is disabled by some dummy box.

 

Now according to my garage, the ECU is behaving badly as

- it does not control the stepper motor any more

- the fuel pump keeps running as soon as ignition is turned on (without motor running)

- the fuel pump keeps running for about 15 seconds after turning the ignition off again.

 

I would prefer to use an uncoded ECU to prevent the hassle of re-programming anything. I found some threads about the MNE101050 which seems to be uncoded but from the information I find, this is for the Rover 114 and not a Mini SPI. I did also find the MNE101070 which is uncoded as well but for the (64hp) Cooper model.

 

 

Now my questions:

1. Do the above symptoms actually indicate an ECU problem?
2. Can I use the MNE101050 and/or MNE101070 to replace my MNE101150?
3. Are there other alternatives?

Thanks for your help

Hmm. Never heard of a bypass for these. Normally the ECU won't run the fuel pump unless the immob is disarmed. I often wondered about this actually, as I used to have a 1995 SPi with the coded setup. It was a passive immobiliser in the sense that the starter wouldn't operate when armed, though also the fuel pump doesn't run. I used to wonder about whether the ECU would run the control loop etc if you put in an override for the starter relay and fuel pump relay.

 

It makes me wonder if maybe your bypass box does this - how long have you had the car?  Did you put in the bypass box / did someone else do it? How much do you know about it?

I do have my car since about half a year. My garage installed the Box and I'm pretty sure it has the code of the fob programmed and basically simulates the fob. So it is not actually bypassing the immobiliser but rather fakes the presence of the fob.

 

My main question is, if there is an ECU which will work in my SPI and does not have that immobility feature?

i have a spi ecu but you will need to get it programed to take the immobilizer out

That indeed seems to be a possibility and even an interesting but also expensive one (even though they seem to have an item at 600 GBP which would work for me). I will keep it on my list. Thanks for the hint.

For now I try to organize an original MNE.

So would a coded ecu work when fitted to a car that origianly had an uncoded ecu fitted,i have a spare coded ecu but ive never tried it to find out.

Do you have an uncoded ecu in a SPI 56hp with single plug? Which MNE number does it have?

I think 600 gets you the ECU, whereas 999 will get you a full kit including new upgraded throttle body so depends really on if you want to get more out of this than a replacement ECU and if you'll get any real benefit from the upgraded throttle body which will likely be dependant on your engine spec. You'll get the benefit of the ECU being programmable either way.

I'm currently not really looking for tuning my Mini. But still courious about the graphics they are showing. Is the blue line without the kit and the red one with the kit installed? (Thuss adding about 6HP using the kit?) Or does this mean that you can get more than 80 HP on a non-tuned SPI just by fitting the kit? That would actually be stunning :)

[alchall]

I'm pretty sure the blue is without and red with the kit and I would expect the gains to be less for a stock engine too.

My car ,a cooper has an mne101070 fitted (alarm has been removed) and i have a spare 101150 from an equinox i bought years ago as a spare as it was too cheap to pass up just never tried it on the car,both are single plug ecus.

[Natron]

I have the possibility to test an MNE101040 as replacement for my MNE101150. Does anyone know if this work or how I can check if it is working as expected?

[FlyingScot]

If it's the same garage who fitted the bypass let them sort it out?
There are two ways with a MNE101150 1) programme the MEMS so it doesn't wait for the digital code from the 5AS ( you need to send it to ATP or similar) 2) a unit which injects the EKA into the 5AS to disarm it when you turn the key.
Anything else is a bodge and could be dangerous - the fuel pump is controlled by MEMS via grounding the MFU (relay box), if this is bodged to run at other times....not good.

You are correct the MNE101050 isn't for a mini and the non immobiliser version of yours is the MNE101040 which was used on the prior model.
Cooper and non Cooper versions of MEMS are not the same so 101070 (101170) which are Cooper non immobiliser and immobiliser versions respectively are not substitutes for 101150 or vice versa.
Immobiliser versions send a code which the MEMS matches, so "spare" immobiliser MEMS are worthless unless you match them to your MEMS ( or get them programmed to).

This should work, but I am not sure if anyone has tried this.....the 101040 was used in the same model up to a certain VIN.
It will work by running the car...but of course the reason for your problems could be several other things.
