Finally got the engine running on the restored Mini 30. Fitted a Mpi manifold to get it on the road.

Running MS3X in fully sequential mode. Hall sensors on crank and cam and LS coils. Twin widebands to monitor AFRs on inner and outer cylinders.

The engine has been built for turbo use but decided best start NA.

Good to see you're still developing things Paul.

I would say good effort but its much more than that.

Keep it up its interesting to see new developments.

Looks really good, is there a build thread for the engine? will be interesting to see the results as well

There is a build thread "budget 998" should find it.

I just realised that the OP suggests that we were having problems getting it running. That was not the case. It was just a matter of getting the motivation to make some progress.

Yesterday we managed to get oil pressure... easy enough if the new loom had not had a disconnected link for an inhibit switch hidden behind the heater :(

This morning we saw synch on the ECU after a slight mod to the hall sensor input.

Checked the fuel pump for operation, fuses in the coils, check the accuracy of the spark then fuses in the injectors and tried to fire it up.

Didn't fire straight up but kicked back a bit. After reducing the cranking advance a tad, off it went :)

excellent ,, I really like the way your simplifying this .

Good work Paul. Glad you got your motivation back.

So is this this running two injector outputs from the MSX to a single injector? If so did you have any issues wiring them together?

Good stuff.

How soon before any datalogs ?

Re. the motivation thing, similar here. I'd completely lost interest (apart from messing around with some extra electronics) for nearly 18 months until I took my daily in for an MOT a couple of weeks ago and the garage owner and MOT tester demanded to know why I still hadn't finished the Mini and brought it in for its test yet.

Anyway, another question - why the hall switch in the old dizzy location ? I thought you had got one working on the back of the cam sprocket (thus potentially saving a lot of space).

No, this is just simple two injector outputs but will have staged secondaries once we add the turbo and new inlet manifold. I'll probably try the closed loop/two drivers/single injector thing on my car. This is my middle lads project.

It'll be a while before we get any datalogs. It's not my car and I'm taking a back seat with the rest of the build, just helping when required.

The cam sensor in the dizzy body was the cheapest and simplest way forward in this instance. I have the cam sensor on the back of the cam sprocket on the other two engines awaiting cars to fit them in.

Good to see you back Paul. Glad the install went well. I thoroughly recommend getting the megalog viewer premium package. the 3d plots are so useful for mapping the AFR balance. it calculates custom fields so the AFR difference is easy to plot. You can import many logs to get a whole hoard of data points.

Just got prompted by MegalogViewer to upgrade when I went to check an old log file.

Very useful set of new tools. Makes it easy to see where you need to make adjustments to the injection timing. We had a spreadsheet all setup but it still took time to import the data.

Having a problem with the TPS on this build. Looks like I've wired it up wrong and blown F2 *frown* Easy fix though.

Any further development on this Paul? Have you got a 3D plot of AFRs?

We sorted out the TPS problem.... broken connection.

The car has been mechanically complete for a while now. Axel drove it in and out the garage at the weekend.

We waited until the weather improved before fitting the headlining and now the interior is going in.

Should be going for an MOT in a few weeks :)

It will be good to have a running mini again. It may provide the motivation to finish the other two.

Hopefully soon get some data-logs.

Any body interested in a "how to" write up on the mapping and injection timing setup?

Paul,
are you interested in my injector timing map? I'm now pretty much there with having balanced afr's across the whole map without the need for closed loop control. (I'm using fully sequential, whereas I know you were talking of keeping the long pulse method).

Very interested in your map.

We are going to start it off simple with the long pulse, but I would like to try the 2 short pulse method at some time.

I'd recommend going straight to 2 short pulses per port, I found there was a lag in throttle response with the long pulse due to only injecting half as often. Also, it's a lot easier to tune and seems to be less influenced by coolant and air temperatures. I'll put something up when I'm back from work.
