I have Celtic Tuning doing a remap on my 2.0 2011 Ti in August. £295 all in. When I bought the car, I thought it was the 170bhp, but after googling my engine code and other stuff, I find it's the 136 bhp, which explains why it's so slow. As far as I'm aware, it has the C635 gearbox.

Celtic Tuning's map will take it to apparently 215 bhp and 352 lb/ft. This is exactly the same as stated on their 170bhp 2.0 remap's.

Is there any risk I should be aware of with regards to reliability of it afterwards?

I've used Celtic Tuning twice in the past and their remaps are top notch. I had a remap on a 1.9 GTD some time ago and the clutch was starting to slip when I sold it about a year later. Putting all that extra power through the drive train has got to have some sort of effect. Still, well worth it though...

Maybe get them to do a conservative remap to 170?

Atleast that way you won't be shortening the life of your components, do you really want to shell out £300 for a remap when in 6 months to a year you're going to then need a new clutch and possibly gearbox?

From what I gather the C635 box should be fine as long as you treat it with a bit of sympathy and have good quality clean oil inside it.

I am planning on getting my Giulietta done, and the gearbox was one of my concerns.

It is certainly a better box than the M32 in the 1.9, and plenty of those have been remapped.

Sounds good, what did you get yours remapped to? No other issues regarding the map?

This is what I'm planning on, I'll keep in mind that there will be extra strain on the transmission so I'll be smooth with it.

I think they can handle the torque ok (same as the M32) but due to the design lubrication is a bit marginal on some of the bearings..

I have some Fuchs Sintofluid FE 75W ready to go in mine as it seems to recommended.

Right so the remap is done and I've been driving it for 5 days. Mine is a 2.0 JTDm, and I believe it is the 136bhp.

Technician arrived in plenty of time at my workplace and got started promptly, I left the keys with him and it was done about 1.5 hours later. I went for a drive in it after it was done and it didn't really feel any different. I made it clear before the work was started that I don't want any of the side effects such as smoking, clutch slip, etc or I will request it changed back. So the extra power is definitely there. Delivery is still very smooth generally, although on 1st and 2nd a bit of a kick when turbo comes in. It's not a big kick in the teeth, but it's there. 1st and 2nd gear seem unrestricted now, and there is more power for the length of the rev range in 3rd with good pull. Technician said only 0.1bar extra boost on the map. Looking at it on paper, my improvement is 136bhp to 215bhp. It doesn't seem like 80 bhp of a power gain, but then maybe that's what 215bhp feels like I'm not sure.

I'd glad I haven't witnessed any side effects yet, the car never smoked at all before, and it still doesn't. EGR is not blanked but it's deleted from ECU. Apart from the pull you can't tell it's been mapped, and that's what I wanted.

Giving it a few more days, I'm really glad the extra power is there. For £295 I'm very happy with what I got. Wouldn't have paid any more though considering the difference.

Providing the condition of the car sticks, I'd highly recommend Celtic Tuning on the 2.0 diesels.

Doesn't sound right. If you've got 215bhp you should be hanging on for dear life when you boot it. I had my diesel GT done a few years back and it went from 150bhp to 210bhp (or that was the claimed figure) and it transfored the car. I couldn't believe the difference.

I've used Celtic Tuning twice now and they have been very good. Have you tried really booting the car to see the difference. In gentle driving you probably aren't going to notice the extra power..

I'd love to get a map done, from 150 to 190 to keep it on the safe side, but the figures of over £1,000 for a new clutch and £2500 for a gearbox rebuild give me the shudders. If you're only booting it 1-3 times a week, is it really going to affect the components if for the rest of your time you are driving as per before, aka normal driving?

I gave it some boot yesterday chasing a Subaru, flooring it I was close to him, but wouldn't have been able to take him - it was in the wet though ;p. For 150 brake it's not bad.

I agree,

I had my 1.9 mapped from 150 to 180+ (IIRC) and that made a huge difference.
I've also had my current 2.0JTDm mapped from 170 to 210 and once again the difference is more than just a little bit noticeable.
(no smoke or any side effects, just lots and lots more power)

It shouldn't make a lot of difference in 1st gear,(and maybe second) the std power is more than enough to get the traction control working if you want quick get away so no point increasing the power in the lower gears.

Take it for a spin on the motorway (or a fast dual carriageway) it should pull like a train in 3rd and up, if you don't notice a difference I'd ask for them to check it (do it again)

I haven't used Celtic for either of my remaps, but I have read good things about them on here, if your not happy (or even sure you can tell the difference) talk to them, I'm sure they will do what they can.

Don't get me wrong the difference is there. It definitely isn't hanging on for dear life. If anything 1st and 2nd are more transformed than anything. Not broken traction yet. 3rd onwards there is definitely more consistent power I just don't know if it's 215bhp. Maybe it is I don't know ?

I boot it on most my journeys but to keep component stress minimal I only floor it on 2nd or 3rd gear over 2k rpm.

Maybe I'm used to the power sitting in other people's cars I don't know. Was in an M4 the other day. Obviously I'm not comparing it to mine, but THAT'S hanging on for dear life.

I am happy with the result it's worth what I paid and no side effects was the priority, so don't get me wrong, not complaining just feeding back.

How much does a dyno run cost?

If your happy with it thats great and you have got your moneys worth.

:)

If your car was the low power 136BHP model and you aren't amazed by the increase (holding on for dear life) then you haven't got 215BHP now, probably closer to 170BHP.

But lets not take anything away from the remap, If your happy then thats all that matters.

Don't bother with a rolling road, that will just cost you money and probably disappoint you, (Real world figures are generally much less than people expect, I used to have a Mini that was a real rocket ship, I used to chase 3 series BMWs down the motorway (back when classic minis were common) it produced 60+ BHP at the flywheel (just over 40 at the wheels) which sounded rubbish way back then, but I scared the crap out of a lot of much 'faster' cars)

Good to hear that your happy with it.

Not sure the claimed 352lb/ft is going to stand up to scrutiny, this is similar to a 4.7 V8 Maserati. Maybe it should be Nm. This would put the remap near to a 2.4 stock which is not the fastest of cars.

Maybe they gave it an economy map along with the EGR delete?

You will get more power slightly, but as the name suggestst is it meant to increase fuel economy.

I have had turbo petrol cars chipped before now, adding around 40bhp (220 to 260bhp on my Fiat coupe), and you certainly know about that increase. You increase is supposed to be twice that, from a lower starting figure.

Is the 136bhp engine the same as the 170?

I am wondering if it isn't the same as on the 140 and 170bhp Giulietta, where the 140bhp version has a restictive intake and smaller turbo. In that case you won't gain as much power and torque.

I asked him after the drive if it was the 215bhp map and he said yes.

The problem is I don't know what 215bhp feels like. I know what 300 and 400+ feel like, but not 215bhp. 2nd gear foot down does launch you a lot better, but doesn't break traction or nothing like that. Maybe it's because I'm on Acceleras :biglaugh:

Once again, you can feel it, 1st and 2nd are transformed. I just can't gauge if it's 80bhp more. Let me iterate again though after driving it more, I'm happy with the boost I got and for the price I'm not complaining.
