To superchip or alternative?

[mapleleaf]

I had a tunit box fitted to my previous ML270cdi. made a huge difference. I notified my insurance company and they didnt increase my premium. i left it on the car when I sold it and informed the purchaser accordingly. http://www.tunitlancashire.co.uk/

I wouldn'nt waste my money on this. If you want more power, trade it in, buy bigger

I cant see why anyone would use superchips when a diesel tuning box is £350 cheaper and can be added or removed in minutes - whereas superchips would charge you to put the mapping to standard again when selling the car.

I've used a tuning box on a Focus TDCi and it worked a treat - loads more torque and far better fuel economy when driving carefully.

Are there any "real" advatages in spending more than triple for superchips?

And loads more smoke using tuning boxes if they are not set correctly!

One way of avoiding detection by camera..

I'd be interested to see how they did this on an atmo engine. I think 150Bhp out of an atmo 1.6 engine is pushing it a bit..

Honda B16a engine - in 1989! - 1600cc 160hp, modern Integra DC5 220hp from 2.0 in 2000

My Wifes 1.6 daily driver was rolling roaded to give figures of 178hp (in as much as RR can be accurate)
My 2.0 NASP CRX has over 240hp (depending on the set of rollers you chose to believe it has up to 248hp) but that is also bourne out by verified performance figures

100bhp/litre is still a good figure buy todays standards but is much less of a holy grail than it was 10/15 years ago

A Mini engine aint no Vtec that revs to 4 Billion rpm...

Engine: 1.6 litre, 4 cylinder/16 V

Max. output/hp/revs: 66 kW (90 hp) at 5500 rpm

Max. torque/revs: 140 Nm at 3000 rpm

90hp to 150hp with a remap just isn't going to happen on an atmo.

Throttle reset?? This is new to me, what is it? Can I do one? Is it recommended?

I was wondering too whats a throttle reset? Or is this a spoof story?

 

[Dieselman]

It resets the accelerator pot minimum and maximum settings.

IIRC.
Ign on, accelerator to the floor and hold, Ign off, release accelerator. Leave car for 2 mins before Ign on again.

Not really, my bike is under 1000cc and that makes about 185hp - Most 600' sports are up to 120hp, - what's the difference ?

They don't have enough usable torque and generate power as a result of very high revs. Power is a theoretical figure which has virtually no real word use.

This is why F1 cars up until recently were chasing the holy grail of 20k rpm+, and also why the FIA now limits them to 19k rpm IIRC. Only one way to get more power from an engine - get more air through it. Only 2 ways to do this, higher revs or denser air(forced induction).

And this is partly why F1 has become so boring. power will only give maximum speed, but if torque is reduced that will be at the expense of acceleration, which is why we now see not only the cars built for speed, but the tracks also.
The bends are softened with track extensions, and the 'impressive' tops speeds recorded are preventing overtaking by dint of the aerodynamics.

If power was restricted to say 450bhp and the engines tuned more for torque the racing would be a lot more interesting as cars would be able to overtake in shorter distances and tighter tracks.

I remember reading Gilles Villeneuve's biography a while ago now and he was talking about the Turbo era saying that the cars were a nightmare to drive. His ideal F1 car would have been a 5 litre V8 with limited revs & lots of grunt, fat tyres & almost no downforce.... Trouble with this I suppose is that it's starting to sound like NASCAR .
