Getting further with a small fix

Since I changed to the more powerful Walbro GSS 342 fuel pump the car has been running out of fuel before the empty tank indicator, this was because the pump is smaller and didn't reach as far down in the tank as the original. I tried to lower it but still not low enough. Peter gave me a great tip to solve it.

This is the original position of the rubber mounts, three of them. The idea is to reverse them so they sit on the outside of the blue support frame. This makes the pump sit way further down than before, about 3 or 4 cm. (Forgot to take a photo)

So far I've gone almost down to the white line after 214 miles (350 km) and that was hammering it a little too; so works a real treat.

I believe a problem is solved

After trying a long list of possible solutions to the rev limiter problem, none of which worked I finally checked the wiring again. The diff speed sensor definitely goes to the dash connector 3, that's why I get rpm and mph displayed in the instrument cluster and it also goes to pin 14 on the loom side of  the X20 connector. But when I took the rubber cover off  the engine side of the connector pin 14 wasn't connected at all, there wasn't even a wire crimp inserted in the hole. This meant there was no speed signal going to the ECU.

A number of people including Dave, John and Karim have suggested that it requires a speed signal from the ABS to the ECU on pin 9. As the Legend has no ABS sensors one could try and connect the diff sensor to pin 9 of the X20 to fool it into thinking there was an ABS signal.

To cut a long story short, that's what I did.

As a quick fix and try out I simply cut the wire (black/slate I think) which went to the X20 connector pin 14 and spliced it to the wire going to pin 9 instead.

Quick fix to save me having to remove  the scuttle - winter job!

X20 Connections
9 - BR/RT-WS/GR/GE (WS/GN) ABS SIGNAL DME-ABS / OIL TEMP>INST M3
14 - SW/WS DME<SPEEDO OUTPUT (M1.7.3 MSS50 M41)

The two test runs I've done so far I've run up to 6,500 many times without any problems at all. I'll continue to verify this over the next few days but it does look good! 

Another thing is the ODB II interface is now reporting mph which it didn't before, although the value is actually incorrect as the pulses from the diff sensor are fewer than from an ABS sensor (ODB shows 10mph when it should have shown about 40). Also the diagnostic error "No speed signal" has disapeared!

Now she fly's !!!

Another 5000 km on the clock!

... but it was well worth it! Home again after a fantastic trip. Sebastian, joined me on the leg to England and we shared driving all the way which worked out really well. We took it fairly easy but didn't stop, total time about 27 hours. 

Leaving Sebastian's apartment in Södertälje

In northern Germany for a P and fill up.

Just arrived at Mums/Grandmas house. Tired? Yes!

The weather was fantastic so we had the top down the whole way accept at night when it was a bit cold. A small issue with fuel pressure cropped up in Belgium but we managed to continue by avoiding heavy footed driving. Once in Kent I nipped over to Boughton Monchelsea so Peter could take a look. To cut a very long story short the last dyno test was a complete waste of time and Turbo Center had screwed up the fuel pressure as they didn't understand the setup. Also the Rising rate fuel regulator was missing a small inhibitor which was needed to limit pressure.

Richards Super Charged M44. 

Kevin taking "Gloria" for a quick spin around the Fleet countryside. Time to get one of your own Kev!

Stoneleigh Kit car show 2013. Black and White! Pauls Legend with the M3 motor. His IVA test was two days after!

This was at the end of the show, so everyone had gone home!

Ian a dyno specialist over at Rochester went through every aspect of the car. Not possible to do a full test because of the continuing rev limiter problem and wrong AFM values

Just arrived - lets hope nothing untoward happens today!

Laurance, James and Dave. Two four cylinder and two 6 cylinder M3 motors.The M3's were absolutely awesome, the power was incredible for such a light car.

James's black M44 (Time to upgrade James, have you persuaded Clare?) and Dave's M3

Peter doing some final fuel pressure checks.

Laurance ready to launch his M3. There wasn't much on the track that could beat the M3's. 125mph on the straight!

Out with Tony for a couple of hours tuition. Pity it rained a lot of the time and I, along with James were black flagged twice!

Forget using wire wool to solve sound issues, go straight for Rock wool it lasts 50 times longer.

It was a really great day. I didn't bother me I was black flagged and I didn't spend so much time on  the track. It was nice to meet up with the others, share some experiences and a laugh. Perhaps we can meet in Sweden next time!

I went to Boughton Monchelsea to what was my local pub 30-35 years ago. Everyone has moved on so I drank alone!

Neil came down to Nürburg on Friday evening with his motor cycle from Stockholm, took him 15 hours. My 10 hours from Kent was a breeze compared.

Wasn't a good day at the ring. Very wet track in the morning and only dried off for a couple of hours.

Queueing up at the start. Because it's classed as a public highway every type of vehicle can drive the circuit and at the same time! 

It's a very dangerous circuit for motor bikes when it's been raining. If you crash you have to pay not only for the damage to your vehicle but also any damage to the track, fencing, shrubbery plus costs for ambulance, doctor, track marshal etc. 

Having the Super Charger installed has definitely transformed the car, it's able to reach higher speeds much easily now. However it's not quite tuned properly and the Rev limiter problem has not been solved and kept coming in at about 5300 rpm. In 5th gear it was doing about 115mph but plenty more revs and power to go. Estimated 135mph or so if the SC can be fine tuned and the limiter problem solved. Peter at GKD has some more ideas I can try.

Unfortunately the power cable fell out of the camera so it only filmed up to about 3km out of 21!

Left Sunday morning at 5:30. Rained all the way through Germany. Stopped so Neil could warm up and I could rest my ars#. We were back in Stockholm at 1 am Monday - 20 hours later!
