159 2.0 JTDM Remapped

I am looking at purchasing a 159 Ti SW with the 2.0 JTDm Engine....

I have heard that these engines are a bit sluggish in the low gears at low revs has anyone had one of these remapped? Does it improve the sluggishness? Is it worth getting the EGR/DPF removed as well? What kinda 0-60 times are people getting with the remapped 2.0 as the stock 9 seconds seems a bit slow

Any thoughts?

159 Ti

I've got a 2.0 TI saloon with a remap and EGR/DPF delete. It drives much better than in standard form, the mid range pull is very very good.

I highly recommend getting it done.

Gus (Alfatune), Aide (AHM) and Adrian (Alfa Aid) apparently all developed their remaps jointly so you just need to find the closest to you. There is a fourth member of their syndicate but I can't recall who that is..

I was going to use a Celtic remap as I've always used them before and been very impressed -but as my car was already mapped by Gus when I got it... I doubt it would make any difference. Its really a standard General motors engine so plenty of people should be able to map it without too much trouble. The thing I like about Celtic eMotion is that you can buy several maps and put them on the car (or not) as you desire. So, my Leon has an eco map at 160hp and a trackday one at 190hp for example. And you keep the original so you can put it back when you sell the car.. its a five minute process to swap.

So since my original post I have now purchased a 2.0 SW and while not too bad it is a little sluggish in the lower ranges.

I have been looking at Celtic as I like the way that they will come to you however looking at the webpages I see the following:

Celtic 215bhp 352lb/ft
Celtic (eco) 204bhp 306lb/ft
AHM 210bhp ???lb/ft
Alfa Aid 210bhp ???lb/ft
Angel 210bhp 326lb/ft

So why do Celtic seem to be able to get more out of the car?

Also I am interested to know about reliability once a car is mapped. I do not intend to drive everywhere at 1000mph but does a remap have any side-effects. Does it increase pressure on things like the turbo and the head?

Does anyone else have the Celtic map on the 2.0 JTDM - how does it fair?

Semantics, statistical sample sizes, all cars are not created 100% equal, take your pick...

One rolling road does not give the exact same results as another... Even within a day the figures can change if compensation values are not 100% correct... Or if ALL sensors are not 100% calibrated (which they won't be)...

Let's say it is true... You are asking about 5bhp over 210bhp The difference is 2% - hardly a noticeable difference... On a 1/4 mile that will translate to 0.1 sec difference

Let's say you then take it to Celtic - there is no guarantee YOUR car will make 215bhp - it might make 209bhp or it might even make 217bhp

I advise checking what gearbox your 159 has fitted first - the 2.0jtdm had three different boxes used (M32, F40 & C630); the M32 won't last long with 350lbft (or even 300) going through it but the F40 would be fine, not sure how good the C630 (used in the Giulietta) is

I have never seen M32 mated to 2.0 JTDm. 170HP variants use F40, and 136HP variants use C635 from Giulietta.

No Celtic map on my car...

Look, the numbers that the various chip-tuner quote should be interpreted as sales-blurb....with the exception Alfatune/AHM....their numbers are conservative.

My car has had 'a bit' more power pretty much from the start by Alfatune and it's been totally reliable...even in its current state of tune....

Have a look through my little Skunk Works thread....might give you some ideas and/or pointers...

I've also got no problems with the Alfatune map, the only reason to go with Celtic is to use their eMotion box so you can de-tune the car to a more eco map (still more powerful than standard) or re-tune the car to something similar to Alfatune, or set back to normal at will. I would ignore the extra 5hp as a marketing gimmick. I've currently got problems getting the Celtic eMotion working with my car right now but if I get that solved I'm happy to give you some subjective impressions. Of course if you are after maximum power then follow the man above

The primary reason I'd like a remap is to get rid of the low down "hesitation"? the car has getting off the line, sometimes on junctions I do worry as its seems to bog down and not pull at all - from reading this forum it seems a common problem.

Have you also had the EGR deleted? I have read that sticking EGR's also cause the lack of power <2K revs?

The Alfatune place is a bit far away for me to go - I'd rather somewhere nearer Bristol - any recommendations?

Did you ever get the remap? I've got mine booked into monza sports and they reckon 15% extra in power and torque is a reasonable expectation from just a remap. That's going to be below the 200 bhp mark and maybe 260ish torque. If everyone is getting much more then that I'm hoping the quoted figures are conservative.

Yeah had mine done at NJS in Pershore nr. Worcester - they use the same maps as AHM and AlfaTune. I had the EGR deleted at the same time, didn't see the point in getting the DPF removed as well since it was causing no problems.

The figures are 210-215 BHP and just below 350lb/ft torque

So a noticeable difference then! I'm hoping mine will be similar as these guys have been tuning for a while and I know their work on the multi airs has been impressive (216 bhp mito)
Ill need to double check if the egr delete is included and get their advice on it. They said not to mess around with the dpf as it may cause issues down the line. I'll just be happy with more pull and hopefully better consumption.

Aside from the BHP numbers, what's it like from a drivability point of view? What's it like with low revs? This is the main issue I think with this engine, in first and second particularly, so if the remap and EGR delete (whilst keeping the DPF intact) don't completely solve it, it'd be interesting to know please.

Really you are looking at 190bhp tops and 330lbft is the norm because any more and they are pushing up the boost pressure and shortening the life of the turbo.

CDTI Surgery went to a dyno day this weekend and my mate with his 1.9CDTI that I mapped and supplied the turbo for went too. They got nothing like what they wanted from their hybrid turbo car and the were running upto 1.9bar of boost on standard cars to get upto 210bhp. One guys turbo even blew up there and then. My mate with his hybrid easily made 240bhp (210WHP) and funny old thing, didn't blow up.

You can get a lot more from the car but how long do you want to keep it is the question.

This thread is about the 2 jtdm not the 1.9 and there is quite a difference both in hardware and software and quite a bit more is achieved (very reliably) with not a big boost increase

The engines have a capacity difference of 0.05ltr and the 2ltr is Euro V compliant, so more restrictive on emissions. I took the difference into account, we do have the 2.0ltr in Vauxhalls too

I'm also looking to remap my 2.0. My main complaint is the poor power/torque in higher gears. When driving on motorway in 6th, wanting to overtake, not much happens when stepping on it in 6th or going into 5th or even 4th. Would a remap help?

Yes it will, a lot.

How much power do you have now?

I think both the 136bhp and 170bhp versions of the 159 remap to around 212bhp and gain masses more torque.
