Anyone 'chipped' their diesel engine?

[gary_m]

Hi,

I have come across quite a few manufacturers who are offering simple 'plug in' chips that they claim can give you between +7 to +25 bhp increase, improved fuel consumption and smoother 'pull'. They range quite dramatically in price and come in all different shapes and sizes.

I was wondering if anyone has actually tried such a chip, and if so did you notice any changes to the cars performance?

I have a 1.9 TDi 110, so a comparison of anyone who has chipped this engine would be useful

My main concern is..........can such 'plug in' chips really re-map the engine or are they just increasing the fuel pump output?

Many thanks

On FI engines big gains are pretty easily achieved - my calibra went from 200 to 300 bhp simple enough.
The chip will alter the boosting and fueling. On a diesel it's the torque increase that is most notable. Bhp is achieved from revs, and diesels don't rev.
Can't recommend a suitable chip, but go off other peoples recommendations, and don't be tempted by a cheap ebay item; sure you would follow this anyway.

I have done a little more than just chipped mine. Hardware changes and chipping have taken mine from 130 to 220bhp. To say I have noticed the performance is an understatement, plus I plan to change more hardware and be around 270-280bhp by the end of Feb/middle March.

I would not recommend a plug-in box off Ebay as it's simply not good for the engine. Save up that little extra and go to a reputable tuner for a car-friendly remap which will give a better result.

The 'cheap' tuning boxes basically fool the ECU into thinking the engine is cold and puts more fuel in. I tried one, and it did feel quicker, but more revvier rather than out right performance increase. But when the engine was cold a very light throttle made it jittery and jumpy and when warm the idle was lumpy. Plenty have said they are good, but I sent mine back. A good remapper should charge around £225 for 180bhp for a 130 model, so about 160-170bhp for the 110 model I think.

Hi David

You mentioned a good remap should be around £225.00? I have been speaking with Devontopia about a remap for the 2.0tdi in a new A6, have you had your car remapped? If so where, were they any good and is £225.00 a realistic price for a decent map?

Cheers

Mark.

Haven't had my car remapped (yet!?) But I did read about a Golf Tdi which he extracted I think I remember correctly 180 and 330lb/ft. The Golf did need a new upgraded clutch due to all the torque!! But Jayson at Chippeduk can tailor the map to suit you, he has been doing it for years and I know him through the BMW forums where he started and had my Coupe sport remapped by him. http://www.chippeduk.com/ Prices start at £225 - it depends on vehicle and what you want doing.

Thanks, I will take a look at the website. Do me a favour and let me know who you decide to go with I am just bedding my engine in for another 700 miles and then I will be spending my hard earned cash.

Cheers

Hi Devonutopia, What cc is your skoda is it the 1.9 tdi only reason i ask is i cant find a listing for a stock 130bhp Fabia?, 100 bhp in tdi form or 115 bhp in 2.0 form im guessing you have had your car on the rollers , is that bhp figure you are quoting at the flywheel or at the wheels?

Ps im not knocking what your quoting, just a little shocked, more if it reachs 280 bhp i would of thought you would be picking up drive shalfs and gear box internals of the road

The engine & box is pretty bulletproof to almost 300bhp, plus I won't abuse that power. gradual merging in, none of this clutch dropping stuff. Already left one CV joint on the tarmac at Santa Pod last year....

The Fabia comes in 1.9 TDI and 1.9 vRS. The TDI is a pd100 and the vRS is a pd130. Both engines are 1896cc. I'm quoting at the flywheel.

A guy I know chipped his Jetta 1.9 TDI and put on a performance exhaust system. The window sticker said 49 mpg highway....he is now claiming a substantial power increase, along with 60 mpg highway.

I love that TDI engine!
