TUNIT for CEED 1.6 cdri

[promethian]

Has anyone got or used a TUNIT unit on thier CEED?

I am seriously considering fitting one of these.... not necessarily for performance measures but to increase the efficiency of the engine and thus increase MPG.

I do a lot of miles and have already hit 10,000 miles in 6 months.
The 1.6 CRDi engine has been successfully re tuned from 115 to 150 BHP with one of these units.

I drive mainly rural with a top box/ some times trailor fitted with lots of stops/starts as part of my business. I generally get 45MPG on the trip and reckon with one of these units specifically tuned( You can set your own power curve via a laptop on the fly) I could get 50+ MPG easily.

I've calculated that with the current price of diesel one of these units would easily pay for itself within a year and I intend to keep this car for a good while.

Anyway....any thoughts?

warranty issues

The tunit unit is removable and does not change the mapping at all, it is a piggyback unit.

See no evil...lol

Don't forget to factor in the increased cost of insurance and then start saving for a new clutch

[promethian]

Have checked insurance and it is a minimal difference .... and don't intend to race the car so with the way I drive the will have no effect on the clutch... only a bad or wild driver could wreck a clutch.

Going to fit a K & N Filter this weekend.

As an off topic point...... has anyone else noticed that everyone is driving around a LOT SLOWER lately?

Well there you go then, as long as you don't go 'bad' or get 'wild' all the oily bits will be just hunky dory

Go for it, sounds like a snip at around £300 to £400 pounds, but with with the anticipated 10% fuel saving it should pay for itself within a few years

See, the trouble with all this is that you only enjoy the fuel saving benefits by using the increased torque and changing up at lower revs to make use of it, but doing that puts undue strain on the transmission leading to premature wear / failure. Now to avoid this you need to change gear at higher revs, which tends to wipe out the fuel savings.

Yes the car will be quicker, and yes you can 'drive around' the clutch issue, but you won't save any money, you'll just get where you're going quicker.

Just my 2p's worth...

Oh, and what's the K&N going to do? They don't flow any better than a clean paper filter and cost about 10x as much. Just cut the service life of the original in half, it'll be cheaper in the long run.

One last tip......

DO NOT over oil it - it will fcuk the MAF and once the garage see it or finds the residue you WILL be stuck with the bill.

Happy day's

Hmmmmmm... ok Bunker your a pessimist for sure.. lol.... but you've made me think... so I'll do some more research.. found a tunit unit for £150 so still tempted.

Well that's a really good price if it's a genuine TUNIT box, so give it a go, you can always sell it on.

Would really think carefully about the K&N though as airflow is generally restricted more by the 'plumbing' itself and the design of the air box rather than the element.

K&N's were great 25 years ago when you could throw away the nasty frying pan filter housing on your RS2000 and bolt a lovely free flowing replacement straight onto the top of the Webber. Ah, fond memories

I have used these units before (Sorento & Picasso) and also tried Superchips. I felt Superchips gave the best improvement though it did require the chip in the ECU to be changed.

I keep careful MPG records, recording mileage and fuel at every fill-up and then plotting this on a spreadsheet. In every case I have found no improvement in MPG, though with the re-mapping the car did feel better at overtaking.

So, do not build up your hopes, if you continue to drive the same way you are unlikely to see an improved MPG.

If you want to really make a difference change your driving habits. I recently did a round trip of 350 miles; before setting off I emptied the boot checked the tyre pressures and ran without the air-con. I restricted my speed to 55 MPH and used the cruise control. The journey included motorway, ‘A’ roads and ‘B’ roads. I achieved 66MPG. On the previous trip where I travelled at the speed limits carrying more weight (2 other people + Luggage) I only achieved 54MPG.
