A friend has bought a 1.9 diesel Octavia 90bhp and is looking to up the power (thinking of around 130bp)

Does anyone know of any drawbacks / can this cause damage?

Can anyone recommend a good tuner in the south east?

Thanks

I am not sure you can re-map ecu on a 90bhp TDi you can on a 110bhp TDi but you only get an extra 25bhp for £339? is it worth it? you will have to search your soul for that?

Why doesn't he just buy a better car? if he wants more horse power I would have bought a really nice fridge freezer, one of them American looking ones. He obviously bought the TDi for it's nearly unrivaled fuel economy (I got 63.5 mpg on a motorway run) but that was chugging along and they are dull and uncomfortable to be polite. to get more power while keeping reasonable economy he should have bought the executive 130bhp Peugeot 406 HDi. it's got all the leather, toys air-con etc and good fuel economy, and they are great to drive and fairly fast for a diesel.

The TDI 90 and TDI 110 are very tuneable with the right mods.

On a 90 you could fit TDI 110 injectors an FMIC and a bigger turbo, clean out/blank off the EGR and maybe an exhaust and you'd be putting shame on a lot of more powerful cars.

The earlier cars do map well and still hold that derv efficiency.

Custom Code reccon their phase 1 remap will take the BHP upto 115bhp which with a panel filter and some millers would make a nice difference to how the car performs. Thats not that expensive for that gain and wouldn't warrant buying a new car. We all have our reasons for owning what we own maybe the OP thought about the 406 but didn't like the look of it.

I can't think of anything to worry about just make sure if tuning the engine make sure it is well serviced and it should see your friend well.

The real trouble with modding such basic cars for such small gains is the insurance/hassle - you could run a really decent standard car with real go, for a lot less money - just change the car, easier all round.

MY 90 bhp octy has a tuning box , pipercross panel filter and uses Millers sport 4 every fill up.I always get 55+ mpg ,dont produce hardly any smoke (even with the box turned up to 11 ) and get some seriously funny looks from luxury car drivers when i pass them in my baby octy:D.You dont need to spend a fortune on a car to make it that little bit more nice to drive ,and i am certainly very happy with the performance of mine especially still getting nearly 600 miles out of a tank :thumbup:

One thing to bear in mind is the age of the car...

I used to have a 1999 90bhp Octy, it would have needed the ECU chip replacing,

the serial port under the steering wheel was purely for certain diagnostic functions, not re-mapping.

IIRC cars from 2000 onwards can be "re-mapped".

There's a three letter engine code, (in the boot floor, in the serivce book sticker), try to find that from your friend & then search for specific issues based on that.

Those older pre-PD engines when looked after, last very well and provide un-rivalled fuel economy.

This is what I thought - earlier ones (TDi 90bhp) they can't to re-mapped?

Good eplanation Darren

The earliest TDI 90 indeed need a chip swap, but it's not hard to do. The newer ones can be done via the diagnostic port.

Cheers folks, When he was looking for a car I did pick out some 406 for him but he has an aversion to French cars + he was very impressed with my Octavia a MkII 1.9 diesel.

The deciding factor was that his Octy was v clean and he got a good deal when cash was short, now he's earning a bit more has decided to get it tweaked.

Well if you can find a 110 in the breakers yard an injector change will instantly up the power.

I normally agree with you ..... however ... .are you quite sure?

The fuel pump is still told what to do by the coding in ECU map,

just because the injectors will allow more fuel to be squirted in,

doesn't necessarily mean the pump will send it to them?

Additional info, I've remembered....

My old motor was an AGR (engine code) & that had a unique turbo (& fitting), that ultimately was the weakest link, most tuners reckoned on 120bhp before that turbo would melt. However, the later engine codes were more tuneable, with the aforementioned bigger injectors (& a remap).

Hope that helps ... Darren
