Technical Horse Power

[strokov]

Good day everyone,

I'm looking for a tuningkit for a punto mk2.
when I look at the motor it's an engine of an Alfa 156 19. JTD (with 110 HP)
for the punto, then downtuned it to 80HP.

is it possible to tuning it back to 110, or is that the max. power 102 HP
with a kit like www.tuningbox.com or something like that.

thanks in advance

Greetings
Strokov

hi there

yes the power can be got back and more, there are a couple of jtd owneer who have had there cars ecu remaped by a company caled angel tuning

www.angeltuning.co.uk

i think it costs about £300 but the horsepower goes from a standard 80bhp to about 120bhp i bielve.

this is a review i have taken from there site by someone who had thre jtd remapped

Fiat 1910 JTD Punto
Wow! Our remap provides somewhere near 125bhp form the original 80bhp without any further modification. Torque is up to over 190 lb ft which makes acceleration very brisk from a standstill, and mid range punch for overtaking with or without dropping down a gear is stunning. The top speed is far more than we would promote but lets just say you will immediately receive a lengthy ban!

The fuel consumption we achieved before the remap was 45.8 mpg on average, after this remap it improved to over 48mpg. We can't understand why it should improve that much as we were expecting it to decrease slightly and will ask people to expect that to occur rather than improve. On one 220 mile round motorway trip (including the M25) we achieved over 52mpg - at an average mph of, well lets just say 70 shall we!

One issue that occurs on a number of standard Punto is with selection issue on the gearbox. We have had no issue with ours in over 4000 miles of hard testing so we think it is a case of if you were going to have problems, the remap is not going to make any difference to this. Lastly all the additional torque may induce a small clutch slip at peak torque on high mileage versions or on clutches that have been "ridden". Our demo car had slip even before we remapped it (28,000 miles - 3 years old) but it hasn't got any worse since.

I took a guy out in a demo who went white after 1/2 a mile and said "OK I think you have proved its quick....can we slow down now"

If its any help, I fitted a tuning box to my 2001 punto jtd elx, from dragon performance . It made a significant difference, I wouldnt doubt their 30% power increase claim at all,it took around 15 mins to fit (connects in line with the fuel pressure sensor), it works very well, on my 30 mile commute to work, fuel consumption hasnt really changed, and its stopped the 'running out of breath' feeeling you get on a standard engine above 3000 ish rpm....... if you do boot it quite a bit, you will use more fuel, and put out more black smoke, but at least you have the choice...........

 

[alfanige]

Yep a remap gives lots of power and very little black smoke (none on most cars) as its making correct use of the information being sent to the ECU. The problem with cheap tuning boxes is they only alter the post ECU fueling signal which then over fuels the engine and cuases bore wash. Because they only alter the fuel signal that why they only get a small power increase and the black smoke.

The 80 engine has different injectors and turbo form the 115 1.9JTD engine, its not detuned as such.

Which leads to the question... Can we change the injectors or bolt on a bigger turbo on the Mk2 Punto Jtd's, bigger intercooler ? or is this a case of just not worth it for the cost ?

 

[johnstoke]

I agree with the above, basically the box i have fitted has jsut upped the fuelling, though it works well, im going to look at a proper remap in the spring

Yes you can, although to be honest its not quite as straighforward with the turbo. I wanted to do this with ours as I thought the Multipla turbo would sit straight in, but it doesnt.

 

[gregit]

So injectors and a Re-map ? or just the re-map ?

In all honesty, I would do the remap and a CDA, then see if the clutch can take any more! There is no point in spending huge amounts of time and effort if you can't get the power down. The problem is there are no uprated clutch' for the JTD except the Valeo one which is some 15-20% better, but thats not really enough.

Good Day,

thank you very much for your quick respons, i'll take a look at the solutions.
80 HP's is nice, but with 20 - 30 more it's much nicer

I heared good reactions about the "tuning boxes", but when I hear about these remaps... I have to think, a remap sounds allright.

Thanks

Strokov

tuning boxes do work very well, ive had one on for 6 months, but when funds allow, i will be going for a full remap. ive thought a few times about puttign mine on ebay coz pennies are tight at the moment, but when ive removed it, i have thought..this car it gutless......... so refitted it......... they help greatly with torque, off the mark, and point and quirt driving is significantly better with a tuning box though once in a while, i do get a little clutch slip.......... to summarise, the tuning boxes are worthwhile (ive got a dragon performance one) but i think a remap isa more engineered solution. Doeas anyone know if a remap causes any issues with smoke testing at mot time, as, of course a tuning box is removable. b.t.w........... strokov, where are you located, if you are in staffordshire, then 'd be happy to take you out for a quick spin in mine, workload permitting........ though dont ask me to drive like an idiot, but there are plenty of hills where the extra torque is obvious

 

[alfanige]

Firstly becuase the remap doesnt over fuel the bore like a tuning box you will get less smoke with a remap. If we had to detune cars every time they went for an MOT we would spend 1/2 our time detuning - we have never detuned a diesel of any description for an MOT!

 

[johnstoke]

hi alfanige............... once ive cleared a few bills, think i'll be havinga proper chat then heading down the m6/42/40 to you......... i reckon the box is overfuelling.......... m6 is busy driving home from work (j18 to 15) so im trundling along at 60ish...... when i boot it up the bank when i come off the mway. i get a large cloud of dmoke for around 5 seconds then it clears....... sounds like excess fuel accumulatin doesnt it............. tho hopefully in the exhaust, but if so, it isnt going to do the cat any good.......... ill contact you via the angeltuning website during the week for more info, cheers

Good day,

Last Wednesday I chipped my Punto Mk2 JTD!
I did it at www.squadra-tuning.com, this guy is really great.
125bhp and 230 Torque :slayer: , the original plan was 250 torque, but the car didn't like it.

this is the torque diagram::: :worship:

I'm sorry for the language in the picture, but I'm from the Netherlands.
I'll try to explane, Red is 125bhp chip-mod, blue is 105bhp chip-mod
Black is standard

this is the horse diagram::: :worship:

colours ditto red, blue, black

It's something, had to do much earlier.

Greets Strokov

btw, sorry for the poor english

 

[toms white punto]

hey could you just turn the boost up on the turbo? thats if it has an hairdrier on it?

 

[Hellcat]

What was the cost like Stokov? Looks good if the graphs are to be believed!

 

[strokov]

Hello,
The job cost around 600 euro's
There were two versions 105bhp and 125bhp
The job with 105bhp is cheaper!

and on the question about the turbo. 2.2 bar !
There is one thing you must check and that's the connection of the rubber "tubes?" standard the turbo gets 0,8 bar and this is always possible. also if the tubes are connected the wrong way, but this is something the tuner knows

This guy really knows what he's doing! He only works with Alfa..(fiat).
There is no black smoke!:yuck: and he always gets the most possible power, without blowing up the engine or something like that.

millenium make some good maps for the JTD. I'm sure the guys at red dot are running a bigger turbo on their JTD. I'll have to find out what clutch they are running as i'm sure Andrea's car is pushing 160bhp plus the torque but they did have it wound up even more.

The CDA is good on the JTD too, i would certianly recommend that. GSR also produce a silicone hose for this too.

Also i think supersprint have started making exhausts for the 1.9.

 

[faster4_tec]

I'd reckon they are the same engine, and turbo, just different fuel pump, ecu map, and injector layout/ number/volume.

125brake, and 230lbft in any punto is quite formidable.

You must know that the 230 is in combinatie with 105 bhp
and the 250 is in combination with 125bhp

so there is more
