age is only a number all depends how you feel. 
sometimes I am 25 again and sometimes (after changing a diff on a Herald) about 90!

Mike (68)

just one more step, once you have loaded the GPX file you need to "finish the route" before it show the track on the map.

Mike

does the NPR work with black and white number plates? Been a few places where the number plates aren't read by the NPR cameras 🙂

I have a 3 rail J type OD in my 13/60 Herald (now 1500 engine). I originally used  non OD Vitesse prop shaft but had balance problems so brought a new prop shaft from CC.

A fair amount of what I did was avoiding that problem. The trick is to be able to identify conditions where the manifold pressure is a predictable smidgen below atmospheric - such as wide open throttle at moderate revs - and estimate BAP from that, then use a slowish filter to learn it. After all, you don't gain altitude all that fast so you only need to adjust the learned BAP at the sort of pace it could really be changing at. And when you're driving up a mountain, you spend quite a lot of time at wide open throttle! What surprised us on the Tucson test was how much time you spend at WOT when going down a mountain...

thats a very neat solution!
Maybe you should have tested it in a less fun car!

Back in the tail end of last century, I did quite a lot of development work for Rover on adding altitude compensation to their MEMS EFI system. After a fair bit of development down a dead end, I hit on a theory which needed a lot less work, and turned out to be exactly right. Also, it's the same one used by a number of other ECUs. It needs no setting up other than a few thresholds for using the main MAP sensor to measure BAP if you don't have a second sensor.

thats what MS3 does. When you switch on the ignition and before the engine starts it makes a measurement of atmospheric pressure. So if you dont have an extra transducer and drive up mountains I think you need to stop and restart the engine on the way up!

Yep that happened right in front us, just before heading to the abandoned village.....frightened me silly on that summit bend!

And me and Libby, diff jammed completely couldn't move the car and the car just stopped! And I didnt like the vultures circling while we waited for a recovery truck.  And my warning triangle got hit, runover and destroyed by a German driving an old Golf.....
Anyway another  3.63 diff is in the car, complete with new set of bearings and NOS crown and pinion. I have done 20 miles with it and sounds perfect... Will get some miles on the car over the next few days and try to break it :).
 

BTW anyone using EFI? I have a MS3 system and have added a second pressure transducer for atmospheric correction. Would be interested to see how others have set it up  for correction. Will take the laptop with me 🙂

cheers

Sorry to hear this Mike…. Diff changes are no fun…

10CR and broken diffs are a bit of a problem for me.....
My old 2.5L GT6 with a very broken diff somewhere very high in France in 2013. 

mike

Well it was going well, down to a few items on the to do list, but.....

New 'reconditioned' 3.63 diff has started to whine very badly at 30 MPH, stops if you  freewheel.
Less than 50 miles since I put it in, it started completely quiet and has got steadily nosier and yes I did oil in it!
I will have to go back to the nice quiet 3.89 one I had in it... 😞 
More than a bit pissed off as I hate changing the diff..

Sound file of unhappy whining diff attached!

Mike

Trying to get ready for the 10CR...

New manifold for inlet pressure measurement.

Electric fan fitted at the front of the rad, changed the diff from 3:89 to 3:63, must be age but was a real struggle doing it without a pit. Have changed diffs before but this one difficult... 

Found some play in one of the UJ so that's been replaced, slight cracking in a fuel hose so will be changed once the fuel level in the tank has gone down. Exhaust bracket broke and has been replaced. So lots of extra jobs but I expected that...

Couldn't reattach the offside handbrake cable without adjusting it. Don't understand why it was fine before changing the diff...

This was a good opportunity to check over the rear end, need new tyres, rain masters, and some rear shoes.

Hard top on (hood has shrunk, and header rail seems bent. I had ordered a new softtop in May and it's only just arrived). Have fitted a Landover sunroof into the hardtop...

What an intrepid and interesting person she seemed to be 😞

Beautifully put. I didn't know her but followed some of her exploits, such a shame and waste. 😞

Mike

Is everyone ready, seems very quiet on here...
I have an electric  fan to fit, change the diff (3.89 to 3.63) and check over the rear suspension, finish and fit hard top (now with sunroof), and give her a good around service. Lots of little bits to do and tweaking the Megasquirt maps as I am not sure I have the altitude correction set correctly.

Doing it with Jane (the wife) so really dont want to break down...
At the moment on holiday so all I can do is make lists of things to do!

Mike

BTW There is a very good discussion about route planning on the TomTom forum, and how to force the Satnav to follow a track rather than optimise the route. It discusses what happens with routes in Mydrive and Basecamp etc.

planning routes — TomTom Discussions
Post 25 onwards.

There is a very good quote.....
...planning routes is fraught when you need to move the route from the planning tool, which has it's own settings and routing engine, to a device which will most likely have different settings and, if from a different manufacturer, a different map and routing engine. Even devices from the same manufacturer have different settings.

Time to go back to a marked up Road Map! 🙂 

Mike

So you can import GPX files into MyDrive
Pressing 'save to my routes' sends the route to the Satnav as a GPX file. The satnav will follow the routes defined in the GPX files exactly. It wont display the waypoints on the display and wont  use the traffic info data for rerouting etc.
In the  'My Routes' menu on the satnav there is an arrow in front of the filename. If this is a dashed arrow the route is a GPX route if its a solid arrow its a ITN route.
An ITN route can be sent to the satnav by pressing the 'Send Stops' option. The data is now on the Satnav in ITN format and the route will uses 'stops' and calculate the best route between 'stops' depending on the traffic data etc. You can delete stops as you go along and the time display will show time to the next stop rather than the final destination. This is similar to the old, very useful, itinerary  system that used to be on older TomTom SatNavs.
BUT you cant save the route that has been sent to the SatNav and it can only have 20 stops in any one route.... 
 

The alternative to Tyre is MRA Routeplanner which lets you load all sorts of files and then export them in different forms.
There is a free version, I brought a lifetime Gold licence at very good price.

Mike

I have a TomTom GO Premium X.

Seems you can load GPX files in the web based TomTom Mydrive.

Once loaded it needs to be 'finished'  and then sync it with the satnav. Route seems to be complete with all the twiddle bits on it although it doesnt show the waypoints (or whatever TomTom call them) on the satnav that appear on the Mydrive application.
I am not sure if these waypoints can be converted to 'Stops' or POI and then they should appear on the SatNav.

I need to do some more playing.

BTW TomTom now have an app for Apple and Android which can sync routes and they say can download maps onto the phone.
~£20 per year or £3.99 per mpnth with a free 1 month trail. Will have a play. If you use a TomTom then it would be a nice backup.

thanks, will have a play with them.

cheers Mike

Interesting topic.
I have a modern Tomtom but it doesnt do itinerary planning anymore (great shame) it does do POI, but the desktop app will import a GPX file.

Does anyone have a nice complex GPX file from a previous 10CR or similar that I could have to try to import into TomTom drive to see how well it works?

cheers

Thanks Tim,

That's exactly what I need.  I did reach out to the only person I know of locally but it hasn't happened as of yet.  I'm near Sudbury, Suffolk.  I just don't get it; there aren't that many places for a noise this loud to hide!

very active TSSC group in Norfolk that might be able to help, try there forum or if you do facebook they have a group there. (2) TSSC Norfolk | Facebook
I think there next meeting is on monday at The Ringland Swan | Places to eat in Norfolk | Pub Restaurant.

I was given a good tip many years ago, before we moved here. when driving a RHD car in Europe when you pull in for petrol, food etc try and pull into a place on the right of the road, i.e. nearside. Then when you pull out you are less likely to forget and drive on the wrong side of the road if the road is clear at the time so no other vehicles act as a reminder. Worked for me. There was one occasion when I didn't follow the tip, we pulled into a restaurant on the opposite side of the road. when we set off again the road was empty and I started to drive on the wrong side. After a few hundred metres a lorry appeared coming in the opposite direction on my side of the road! I thought what the ... is he doing on the wrong side of the road - before realising it was me on the wrong side!

it did happen on one of the early 10CR's, white herald drove on wrong side of the road after a stop to check maps, we were following realised we were on wrong side of road and moved to the correct side before we could do anything the white herald had a head on crash... 

My daughter helped with first aid, very traumatic...

excellent, I am interested.

So the question is whether I should discuss this with the FIA chap who's coming to homologate our WRC code this week?

interesting is this for the new hybrid cars... 
WRC very exciting better than F1!

MX5 seats in my 13/60 convertible, had cloths faced seats but now have leather (and heated) ones. If I am honest the cloths ones were more comfortable than the leather... The seats are narrow enough to recline past the B pillar. I have mounted them on some home made spacers and use the original MX5 runners. 
I was lucky to find these red and black leather ones that suit the Red Herald!

There is now plenty of petrol around Cambridge, short or no queues but no diesel! 
At least that stops you making mistakes...
