hi guys just remapped my 2002 vito 108 cdi today,originally 80 bhp,
then had a stainless exhaust fitted,
pipercross panel filter,
and a remap

new total bhp =

wait for it

153bhp yes thats right 153 bhp even i was amazed and teh guy who mapped it for me,

he de programmed the original 80 bhp programme and then installed the 120 bhp programme,then he stage 3 mapped/chipped it,jesus christ it flys,
80mph = 1500 rpm

anybody around midlands area or maybe a bit further away my mate maybe able to do it for you also. just pm me

Hi ya, how did you manage to alter the gearing by that much, mine is at around 3000 at 70 and tops out at about 95. Has it got the box out of a 112 or huge wheels? The power is about the same as a 115 so you now have the best of both worlds, the best body with excellent power, cool :)

Something doesn't match up here....

80mph=1500rpm?????

I have a W639 150bhp version. In 6.gear, 70mph (112km/t) = 2500rpm - and I have 235/55 17" wheels - a bit larger than the original. Speed controlled with 2 different GPS.

Remapping doesn't change gearing - and I seriously doubt that the difference in gearing between these two models is that big.

Hi ya, at 70 i would say that the gearing is the same just that you a have an extra gear, it would be interesting to know what you are doing in 5th at 70, i bet its close to 3000 revs.

I think your "tuner" needs his dyno re-calibrating......... Be wary, most re-maps just reconfigure your throttle pedal to give more revs for the same travel.
ie you'll now get (say) 40% throttle at 20% throttle pedal movement, seat of the pants dynos are tricked into thinking more torques.
These engines have a very basic common rail system, with very little to re-map, throttle position, rail pressure & timing, that's about it.

hi mate i will upload my dyno print out showing 153.1bhp as soon as get scanner working tried taking photograph but no good.
my mate has been doing these remaps for over 20 years,
he has a new 150 bhp transporter and he reckons that the torque on my vito is more than his van

Hmmm, I don't think they do a 150bhp Transporter, they do 174 then down to 130ish?

80 mph = 1500 rpm

The turbo on the 108 cdi wont cut in til 2500rpm , and if you make it boost too early the ecu will instigate limp mode ie 2500 - 3000 rpm max .

So does the re-map disable all the safety measures that prevent the engine from sustaining any damage ?

Hi ya, with a remap you rewrite the fuel map that is held by the ecu so that it supply's more fuel thus more power, with a chip you interupt the information between the ecu and injection system and alter it so that you supply more fuel thus more power. You dont alter the turbo at all but you can to give bigger gains. There are ways around fooling the turbo pressure sensors (boost regulator) so that you can run more boost without causing limp mode. You can easily and cheaply get the turbo to boost more and earlier but not by a huge amount, to make a big difference you need to alter the spring pressure on the boost actuator which means you might aswell get a different turbo which in the long run is never economical and worth while.
You can get 150bhp out of the 2.2cdi on mapping alone as merc do this on the 115 and it can be taken up to 200bhp very reliably according to many tuning companys whilst retaining its rather good fuel economy.:thumbsup:

What i was questioning and several others was how does a remap alter the gearing by 1500 revs in top gear :eek:

P.S my turbo boosts from 1500 revs and is making max boost at 2500 revs:thumbsup:

It does not...........!! Gear ratio is a gear ratio........period.....!:eek:

I am driving a 58 plate T5 works van at present (130ps) and it sure is gruff with a fair old growl to it. It pulls in 6th 2000 rpm = 70mph indicated and 2250 rpm = 80 mph indicated, so its very un-similar to my CDi 111.....this records the following....... 2500 rpm = 80 mph indicated.

Any way the posts stating more power for same throttle opening are purely subjective, mapping only puts more fuel in to give a corresponding increase in turbo boost to give a bigger bang.

Another point to ponder then is this; can an economy map be installed to give "economy" at reduced power??:confused::confused:

Exactly :thumbsup:

I will argue that point, adding more fuel does not alter turbo boost. Turbo boost is caused by the speed that the turbo spins at and is controlled by the waiste gate, adding more fuel will alter neither of these but altering the waiste gate and the size of turbo will.

Another point to ponder then is this; can an economy map be installed to give "economy" at reduced power??:confused::confused:
Most engines are set to emit a certain amount of nasty stuff as laid down by law thus they run lean in certain areas of the rev range which means they dont develop maximum power and torque efficiently. When you remap it is possible to get the engine to run more efficiently, make more power thus use less throttle for the same output thus using less fuel and no this isnt fiction its a fact. So a remap can give more power and also better economy. This is very clearly shown with modern motorcycles aswell which nearly always offer more power with better economy when they are fitted with a powercommander or are remaped with a teka box.
Why would you want to remap for economy and lose power? You wouldnt gain anything by reducing power just make the engine work harder thus use more fuel.
There is an optimum size for an engine for the weight it has to move, this is bore out by looking at the fuel consumption figures for the vito range. The 109 is underpowered, the 111 is more econcmical but the 115 is even better and is better than the 120 so it would appear on paper that the 115 is best. This would indicate that if you reduce the power you would also lose the fuel economy

Turbo spins faster therefore more air...........more air requires more fuel to maintain the 12.5 : 1 fuel/air ratio. If more fuel were not injected it would run lean and probably get too hot. Provided you can get the air into the engine then you can inject more fuel............!
However you do eventually reach a point where things get silly and you might as well add another 2 cylinders and then the fuel bill gets silly and then you think sod this and sell it !!:surrender::surrender:

Hi Guys,

80mph->1500rpm :eek:
I would suspect a faulty rev counter. On my 112CDI sometimes at idle it reads 1000rpm and sometimes anywhere between 0 and 1000
