...almost forgot!!!

Look what was on the RR when I got there!!!!!




I like!

I hate to think what this RR session cost you........what a waste of money ? And - did they not sort out the problem there and then?? Surely that's the point of a RR session ? And yes - if I had an SPi I would convert to a carb asap.

As i understand, there are two types of ECU, differentiable by their code and 1 or 2 connectors.

I had a quick check on ebay and it would appear to be a no fuss swap (well that's what the ebay ads said ), I guess you will need the key fob though.

I would definitely be trying that or going elsewhere to a mini specialist, who may well have an ecu lying around!

With your stage 2 head, i would also be considering an after market ecu! there was an article about it in one of the mags last summer!

If the ECU repair place can check it for £15 as their website suggests, and they are fairly local to you, I think it would be worth a visit.

Buying the bits to covert to carb and paying for the work to be done is going to cost more than the £100 for the repair.

As your car is a bit "temprimental" and some of the bits have needed tweaking, its probably better to keep it reliable and standard for now, then maybe do some more mods in a few years when you have the cash.

just think how quick it will feel with 50bhp.

ecu fixed for 100 quid? £100 will definately get you a hif44 and an alloy inlet manifold off ebay (we have a couple at work we could sell you for less than that) other than that your looking at a new inlet manifold gasket, which is a few quid, and a session on the rollers again.

im not totally syre if you will have to do anything with any wiring to the dizzy and coil, but i doubt it. i bet there are tons of folks on here who have converted them.

camco are fine, speak to bruce when you phone then, nice bloke.

I'll call camco today - late now... and see what they say. worst cast - Ive spent £30 on the RR and another £20 or so on the Camco check... but either way! I can't wait to see what 50 bhp feels like! might feel like a mini for once!

but for tonight... seriously need some sleep!

night all... speak again tomorrow after a chat with Camco.

There seems to be a problem with the sender that the VACUUM PIPE that goes into the ECU.

Ok the MAP/Vacuum pipes come out of the inlet manifold, through a fuel trap and into the ECU.

99 time out of a 100 its this pipework and its connections that play up.
The sensor in the ECU can play up but rare.

What testing did the RR guy do to pin point the MAP sensor?

I have to say that the photos of the garage don't inspire me with confidence that the fault finding was correct.

I'd also NOT advise going back to a carb and dizzy, carbs are crud and so are dizzys. You'd end up with a car that ran worse, was harder to start, had worse economy and you'd need to toss around with a choke every morning. Just because you don't understand it dosen't make it rubbish. I would also argue that fault finding on an injected car is easier than a carb. Fault readers are cheap these days, so all you need to do is plug it in and it tells you whats wrong. With a carb you have to have accumulated knowledge of all possible faults to even have a clue, and then you'll more than likey have to change several bits before you get the right one.

As soon as I can i'm binning the carbs on all my cars. My first project is a 7-port head, the second will be similar to the SPi setup, but adjustable.

Well since the SPi doesn't actually have a dizzy that controls a coil, he'd need a complete one. And at least a decat pipe. But to do this conversion legally, you have to replace the complete engine with an earlier unit. And to be able to easily register the change you have to have it done by a garage who will supply a covering letter and proof of the age of the new engine and the VIN of the car it came from. That will cost more than £100.00. When you say you can get around the technicalitites, what you mean is you can get the car an illegal MOT which is fine for you but not for anyone you sell the car to, or for the person you are advising to do this modification here. Please give more resposible advice.

what you were doing when I posted that post at 4am! lol

erm... lol

I don't know what he exactly did to check this...

when he connected it up, it told him that the sensor was MAP sensor was not working, he then checked the filter etc. followed the pipes back through to the ECU, I have replaced the pipes so I know they are not split or broken...

to be honest, I didn't really know what he was doing and when, lol I just kinda let him get on with it... :s (school boy error)

if it is the ECU, is it something that it likely to be fixable? or is it going to be a new ECU job?

if its not the ECU, what else could it be i.e. what else could I check to see whether its got a problem?

I don't know the Spi ECU, does it have an internal MAP sensor?

If so and that's the error code that it gives then should be an easy fix. I would presume it's just a case of opening the thing up and soldering in a new sensor. If the MAP sensor is external, as is common, then it's even easier.

Saying 'it's the ECU' is not much help, if the ECU was properly FUBAR then the car wouldn't start.

What I would do is swap the map sensor (or get someone to do it if you don't have the tools/skills) and if that dosen't work start look elsewhere.

he told me the MAP sender is within the ECU... I will get it changed for a new sender and see how it goes
