MetalMicky08 I know what your on about,I was refering to the post by Rob.In my view,unless you really know what your are doing,leave ecu alone.I realise you had no intention of going this way.

C-Maxer Hi MM,

I think you may have mis-understood me. I am taking your advice and opting for the plug and play type. The Chip Express module is very similar if not identical to the Tunit you have. It works on exactly the same method too, not just a few diodes etc like the cheap ones.

I would never even consider going down the route of altering the std ECU.

Here is a link to the one I have seen...

I would be interested to know what your thoughts are...

Once again thanks for your help and advise.

MetalMicky08 I wouldn`t go down that route as once you have messed about inside the ecu,all sorts of probs can crop up.At least with the Tunit,you can take it off & if you get a newer car with similar engine (check their site) you can transfer it,& I don`t mean just frauds.

C-Maxer Hi MM,

My K&N arrived this week and I fitted it this weekend. The first initial impression was that the car idles more smoothly and it wants to go a little more too. That is hardly supprising given that the filter it replaced was totaly black and real clogged. Even though there are more service stamps in the book than there should be due to reduced service intervals by the previous owner, I find it hard to beleive that the filter was changed lately.

I have seen the Chip Express ones on ebay at 395. They seem to be very much the same as the tunit and are fully adjustable too. I am saving the penny's and will have either one soon enough...

C-Maxer Hi Rob_82,

Thanks for your reply. I dont actually want to make any permanent changes to the ECU as the car is still under warranty.

Cheers.

Yes,I ordered straight from Tunit.It was delivered in 5 days.There are fitting instructions & some pics (probably the ones I sent them!).If you get one & have any trouble fitting it,pm me & I can then call you & talk you through it.It took me under 10 mins.

Rob_82 You could always get the car remapped, around 300.
A k&n panel filterwill make very little on its own, but if you intend on getting a chip/remap and a free flowing exhaust then a panel filter will be of more benefit.

C-Maxer Thanks MM,

I think I have just been convinced that its worth paying the extra for the Tunit over the cheaper versions. I have experience of K&N's from previous motors and my bikes so I know they make a difference. Ultimately I want to get the absolute max MPG from my C-Max and also have the ability to blast it from time to time. I think like you I will use it as it comes and not bother with the set-up.

Your reply as indeed been very helpful and I would like to say thanks very much.

One more question, where did you get it from? was it direct from Tunit?

Martin.

MetalMicky08 Setting it on low (1) would only take it to say 145,mid would be 170.I have a K & N air filter too and it does give about 5 bhp more.I know it`s not much but it does help the engine to `breath` better.With my Tunit,I now have it on 7 & that`s plenty for round town.As I got the car used it did not come with traction so I do have to be careful in damp/wet conditions as torque steer is Very prominant.The main gain of the Tunit is when set to 9 (high) & I`m on a motorway.Say I was doing 60 in 6th,I only have to `brush the accel pedal & the in gear take off is brilliant.I have just come back from down south & had it turned up to 9 & even at 80 mph I was getting 58mpg.The Tunit can be set up by an insaller for you & they use a laptop to tune it to your sprcific requirments,although they do charge for this but I don`t know the cost but I`d think it would be costly - ish.Hope all this helps you.
MM

Richard G I've been told the panel filter K&N for a diesel is not a lot of point
