Tuning Fiat Bravo 120 T Remap Results

As it happens, I accelerated up a big hill this afternoon (dual carriage way - roundabout - dual carriage way up the hill) with a Focus ST behind me. I was taking my time up to the roundabout and could see him screaming up behind me. I had to hold off going through roundabout due to traffic and then got held up behind an astra, but once it pulled over I could floor it from 40 and was pulling away from said ST. I pulled in at 70 as I was taking the next exit.

I guess I'd better not mention the 04 Civic Type R (old shape) either? :D Now it was certainly a VTEC as I heard it kick in as I passed him, but I guess possible it was a rebadged S. Having said that, my mechanic friend tells me a lot of them are way down on power these days.

I remember when they came out and were great fun to play with when my 20VT Coupe was on the road :)
 
I can actually believe him. Considering you can get even a normal 1.4tjet from 0-60mph around 6.2 seconds (my friend has done it). So thinking that he has 200bhp with cat, and with a decat he'll pump out more from that diesel engine, I believe him.

Don't be silly. Unless pointing down hill at a strep incline you ain't getting any stock bravo to 60 in 6 seconds. No way. Not a chance. Plus his isn't a t-jet. It's a diesel multi-jet. Not taking anything away from a diesel but 200BHP of a diesel vs a 200 BHP of petrol will be beaten by petrol 90% of the time.

In fact just look at the t-jet 120 vs M-jet 120 stats, the t-jet gets to 60 nearly a second and half quicker, yet both theoretically have 120 BHP

I never said my friend's Tjet was stock. He's pushing also around 200bhp. I have to disagree with you on the diesel vs petrol. A diesel can beat a petrol, especially of it's got a chip, because usually they can alter the torque curves and let far more more kick in earlier on a diesel vs a petrol.

You said in your original comment your mates was a normal t-jet so I presumed you meant stock. And you can also chip or remap a t-jet so that is invalid. But like for like. At 120 BHP each the petrol will win. Which was the point I was making

Hahaha sorry when I meant normal, I meant that the tjet is normal type of bravo around here and the multijets are a bit more uncommon and aren't normal :D yes I'm sure at stock 120bhp that the petrol will win. But having a chipped 200bhp diesel and a 200bhp petrol, the diesel will do better because of it's low rev turbo, which kicks in more torque at lower revs. which means it can put down more power earlier. The problem with stock diesel is just that the Fiat map on it, isn't quite the best :D
 
I'd suggest some better / wider tyres :D

Still can't get the power down.



Uh ho, sounds like a diesel vs petrol debate is erupting.

It's worth noting I've had a Golf GTD before remap :p

The main issue with diesel is there a load of power in one big fat lump. 2000-4000 and then it's running out of puff. Some petrols will go upwards of 8,000 rpm.

Don't get me wrong, I am a big diesel fan, I've owned 8 cars and 6 of them have been diesel.. but petrols are getting better.

Would I rather own a 2.0 TDCi or a 1.6 ecoboost for example? Not sure I could justify the extra cost of the diesel lump ;)

See I disagree again. I still think a petrol would poop it out for dinner. If diesel was so good why don't formula 1 cars have Diesel engines ;)

We could argue this all night so let's just agree that we disagree :) I'd like to point out I'm not in anyway saying diesels are bad they have the pros and cons as does a Petrol. And In the right car with the right tuning diesels are fun as hell.

Hahahaha well the Audi LeMans car is a Diesel :D I'm all for petrol by the way, I don't like the sound of diesel's on cold days.... sounds like tractor :D but please hear me out on my logic. For a 0-60mph race: The Multijet will be quickest off the line (if remapped to have low end toque curve) and will create a gap between itself and the Tjet (also remapped to have a low end torque curve). So the multijet will now be ahead, but every time the multijet reaches the high end rpm and has to change its gears and the tjet will gain on it. So by the time they reach 60mph the Tjet would've almost closed the gap created by the Multijet at the beginning, yes? So the Multijet should be 0.3-0.5 secs quicker on the 0-60mph. However if it was a quarter mile drag race, no doubt would the Tjet win :D

Biggest problem with a t-jet Bravo when accelerating as fast as possible to 62, is the gearbox. Where a Giulietta Qv changes from 2th to 3th at 65 mph the Bravo had this point below 62 mph. So the Bravo has 2 gear changes instead of one, like most hothatches. That really kills the possibility of good 0-62 time. 6,5 secondes would be perfect possible with 185hp and 1 gear change. My 0-62 time right now is about 7 flat with 185hp.

Here is an interesting link:

Might be worth starting a thread about this in its own right? ;)
 
Those tyres are for fuel economy rather than out and out grip...

I've currently got them as 205/55/16s and I can spin them in 2nd if the road is damp. If you want better grip, will need to be willing to sacrifice fuel economy.

Well, not entirely.

These are the efficient ones; http://www.goodyear.eu/uk_en/tires/passenger/efficientgrip/index.jsp?from=browse

I chose the "performance" version because of the "wet grip". They were more expensive as well.

They might not be Toyo Proxes but really, I shouldn't have to go to these lengths to get power down. It all comes down to poor chassis etc etc

Hahahaha well the Audi LeMans car is a Diesel :D

I knew some clever dick would bring LeMans into the equation :D. You can't class LeMans as a real out and out power race. LeMans is all about efficiency, aerodynamics, reliability and staying out of the pits. Which is where the hybrid diesel comes in - for economy.

Would the Audi R18 4.0 V6 Diesel e-tron go around Spa as fast as Hamiltons Mercedes 1.6 Turbo petrol Hybrid? Doubtful. But which would win an endurance race? The Audi.

Hahahaha I was only really joking about it. No doubt will the F1 car win, but the LeMans Audi is still pretty fast. But yes, as race cars Petrol is king :D and even a ¼ mile drag race, petrol will no doubt win.
 
I'm starting to think these 0-60 times are bogus.

I did 6 runs tonight, with a proper live "computer" hooked up to my ECU. Speed was adjusted to my GPS. As far as I am concerned, this is a much better, true method of getting accurate times.

Again, to make this a fair test, I measured the time from 0-62 mph, or 0-100 kph. It's common to call it 0-60 cause this gives a faster time... but the reality is, you should measure to 62 ;)

Scangauge II measures the speed every 0.2 seconds. So I found it tricky to get 62 mph out of it.

Basically, after 6 runs, my best run was 8.4 seconds at 63 mph.

This car is supposedly running 169 bhp according to the rollers - now considering the 150 T-Jet is apparently at 8.2 to 60 mph.. it kinda makes me wonder.

So, two conclusions;

1. I can't get sufficient power down, I am a rubbish driver, even though I got minimal wheel spin in 1st and no spin in any other gear.

2. People can't take "true" readings and just claim figures based on what they want to see/ hear.

If someone else can get another T-Jet to do a 0-62 in 6.2seconds, a full two seconds faster than mine (as has been said in this thread) I'll be bloody amazed.

Absolutely agree mate, my readings were based on a recording and my ipad timer. And though not accurate give me a good feeling that you can't really get more power down in the car without some serious modifications, just sticking more power in it won't work. The car just isn't set up for silly 0-60 times, I'd love to be proven wrong but I completely agree no body can get a 6 second 0-60 times.
 
Oh aswell, just for reference, an angry driver in a Ibiza tried it on and lost miserably down a dual carriageway. My car just pulled away.

It had the FR body kit... so it could of been the Cupra, FR or even just a standard one with a body kit haha.

It could of been either;

1.8 T with 147/ 177 bhp

or

1.9 TDi with 128/ 157 bhp

Standard figures... could of been mapped for all I know.

Ibiza is a bit lighter than the Bravo, but even so I just pulled away and left him hanging - which made him very angry! Tailgated me like a pro.
