Hey Jayk

I had superchips maps on 3 previous cars from Ren, Audi and BeM and they were all great. But when I asked them to handle the 2.5 dci they said they could not do it via serial ecu chipping via diagnostic port. They reckoned it could only be done by a piggy back box and recommende Tunit - who do have a good reputation. I will do a smoke test on it sometime soon to see if its running illegal or not. I very much doubt it and even though I drive full on pretty much all the time I am still getting a consumption figure in the low 30s

Skindude,

those boxes are tuneable. have you considered a session on a rolling road to get the settings perfect? might cost a bit but could be worth while.

id be up for a rolling road, to tune them properly.

As a induvidual map is far better than All For One ;)

i think the best thing you can do if you are going for a tunable system is to plan out what mods you are going to add such as fan, induction, boost controller, and only then have the tunable system added with a session on the rollers so it is customised for the new upgrades. if you had a programable boost controller there is no reason why you could not acheive the best in all four programs. so channel 1 stock, 2 50%, 3 75% and 4 100%. it was how i used to run my focus, i spent most of the time in c2 which was around 270BHP and channel 4 it produced 320bhp 8)
from my limited knowledge of diesel engines they are inherantly stronger than petrol engines and if i wanted to turn additional power on and off i would go for NOS. it is off most of the time then when you want it just arm the system and hold on :lol: :lol:
 
A few years ago I took the viscus fan of my 4L diesel Landcruiser here in Australia and the first thing you noticed was just how much freer it revved out and the engine did not have to work as hard
I'm about to get my D40 in the coming weeks and I to have a chip sitting here waiting to be installed I spoke with the manufacturer and was told that most chips are only set to 80% and some vehicles you set higher others you couldn't , I have a 16" Davis Craig Fan sitting around not doing anything and I was toying with the idea to fit it to the D40 2.5L with the Availability: 16” = 2120CFM of air it should do the job
Like you said some will have more power some will be less mind you it takes at least 50 / 100'000K's to fully run a diesel engine in and only then can you say yes it made a real difference modding the engine . At 128KW from the factory then say another 20% from adding a chip and another 5 to 8% for the fan it all adds up in the end and should give you a smoother power curve

Have you got the fan mod done as yet ?

was being done at the weekend! however when the chap installing it started pulling the clutch assebly off he tapped the radiator and put a hole in it!!!!!!!!!
now waiting to get a new radiator :oops:
 
:( how are you mounting the fan unit ?
tell me not just through the radiator using those plastic clips you get with the fan unit
or have you made a frame that uses the radiator shroud mountings or what have you done ?

yeah through the radiator, i have fitted loads of these units and never had any issues :D
i will be writing up the how to shortly
 
I wouldnt like to see anyone here in OZ mount an electric fan that way come and drive in the outback and I reckon it would last a week if that . mind you the road in the UK are far better then ours :cry:

quite common here if done aftermarket the fans are really light.
i have fitted them to rally cars and super 7 track cars and in 15 years never seen one fall off or damage the radiator. in fact for the rally cars they are great easy to get on and off as normally the radiator is the thing that gets knakered :shock: if an initial shunt does not do it then a stone later on will!!!! :lol:
 
How did you go did you end up getting the fan installed ? did you find it gave you more power at all ?

removed the viscouse unit and the shroud, you have to be careful when we removed the clutch assembly it pinged off and put a hole it the rad!!!!
we soon fixed that though.
yes it does give more power but the biggest differance is the way it pulls off, and in gear performance which i think makes it drive much better.
was it worth it?
yes i think it was for the gains i have got. :lol:
 
Doese sound good Pictures and part numbers etc would be good as well
 
Did you remove the air con cooling fan as well or was there enough room next to it
did you refit you fan shroud

HMM some pictures would be good LOL
