In Car Entertainment / Re: DAB versus FM Radio
« Last post by Hobo on June 20, 2018, 01:09:57 PM »
I think the only reason they are pushing for DAB is that they can fit far more stations onto the band, when I first got my Civic and found it had DAB I thought oh good, however like you I was not impressed with reception coverage and did not find the quality any improvement over FM.

Unless using a USB memory stick for music, when using the radio I now use FM all the time and very rarely bother with switching to DAB, talking to a couple of other people I know with cars capable of DAB I found they are of  similar opinions.
In Car Entertainment / DAB versus FM Radio
« Last post by Kenneve on June 20, 2018, 11:06:52 AM »
We are being told that in certain areas, FM radio will shortly be phased out, in favour of DAB, so have been experimenting with the radio in my MK3 Jazz.
I'm finding that DAB reception is very variable, in certain areas away from large towns.
On a recent trip from Solihull to Stratford-on avon with the radio tuned to Smooth Radio, the signal was initially coming from Birmingham, but switched to Coventry, around Henley-in-Arden which is really no different from FM reception, in fact there were some areas with no signal at all. On switching to FM in these dead areas, the signal returned albeit in a rather noisy fashion.
So, it would seem that there is no real advantage with DAB, I'm told that the signal quality, frequency and dynamic range, is not as good as FM, so why are we being pushed towards DAB.
The only slight advantage is the signal is either 'there' of 'not there' unlike FM which tends to fade into noisy oblivion.
Has anyone had similar experience with this problem and are the radios and/or aerial system in MK1 & MK2 Jazz cars any better?
Honda Jazz Mk2 2008-2015 / iShift auto transmission oil chain due
« Last post by Steve2011 on June 20, 2018, 10:53:54 AM »
My iShift has done 26k miles and needs transmission oil change 2yrs or 25k miles. The problem is Ive taken the car to three independent mechanic's and non of them wont touch it with barge pole because so-called sensor in the gearbox. I know for a fact this absolute rubbish Ive had it done before it's a straight forward job, oh Ive been given quotes of 170 by a gearbox specialist and other very silly prices, in the end Wimbeldon Honda said they will do it for 48 beacuse Ive got my own MTF oil. My question is what's the big deal about the iShift gearbox in terms of a tramnsmission change?
Honda Jazz Mk2 2008-2015 / Re: Cracked windscreen

Just for info - Having reported my cracked windscreen on 16th May, Yesterday (19th June) it was finally replaced by Autoglass.

No explanation was offered as to why it takes such a long time to procure the correct screen, but then again, the unhelpful chap they sent is at the wrong end of the food chain to have that information.

Here's hoping I don't have the experience again.

It would require something like a quarter of the power to overcome drag at 60 mph as against 110 mph. it would still incur similar friction losses and such, irrespective of the speed (slightly less at lower speed).

Exactly, at 60 / 70 mph cruising it is lightly loaded.

I disagree. An engine is lightly loaded cruising at motorway speeds. It is acceleration, shifting a lump of metal and its contents up to speed that uses fuel. My MT 1.3 engine ran at about 2,500 revs at 60 mph and 3,000 revs at 70 mph. My 1.5 CVT engine runs at about 2,000 revs at 60 mph and 2,500 revs at 70 mph although this varies with gradient.. Cars use less fuel on motorways because there is no acceleration from a standstill and the engine is lightly loaded.
They use less than they would around town, true. However drag squares as speed doubles so there is roughly 30% more drag at 70mph than at 60mph. At 80mph the car is having to fight 60% more drag than it would at 60mph. And at least at 60mph the Jazz can operate its engine in the efficient Atkinson cycle mode.

So assuming the engine I using almost 100% of its power to cruise at 110 mph (which it can) what proportion of its power will it be using cruising at 60 mph? Would it be relatively lightly loaded at this speed or even 70 mph compared to 110 mph or accelerating from 0 to 60 on a wide open throttle?

You have to think about an engines capabilities, not how people use it. Most drivers never heavily load their engine even though it is designed to withstand it.

My Mk3 MT has averaged 50.34 mpg over 31,200 miles of similar mixed motoring in a 27 month period.  Again all data by recording at pump and mileage, not onboard computer.

I do very little motorway driving but when I do, I tend to drive at 70mph and the fuel consumption is noticably more.

It is lashing rain this morning so I decided to monitor the engine coolant temperature as I took Mrs Jocko the 1.8 miles to her work. On getting into the car, in the garage, the coolant temperature was 18C. By the time I reached the hospital it was 69C and as I drove home, the reverse of the route, it climbed to 82C. The normal steady operating temperature is 84C, only going above that when stuck in traffic in hot weather. According to the ScanGauge, I averaged 58.6 mpg for the journey. The benefit of starting work at 07:00 is that traffic is light. It is a different story when I pick her up at 11:00.

I see that Red Bull Racing are ending their ties with Renault for next F1 season and have signed a two year deal for Honda to supply their engines for 2019-20.
