Guest EVSS Posted January 26, 2004 Report Posted January 26, 2004 just a footnote so no flaming.... just had a customers sharan in with a tuning box fitted by v/w. the unit fitted is commonley known as a P box and one of my main suppliers trialed them with very good results about 2 years ago.(decided cost would prohibit aftermarket sales) when fitted by vw no warranty problems apparently cost customer about 500 pounds fitted to a 130bhp sharan. This probably is why on a earlier post Listers were selling 190bhp sharans. gary Quote
seatkid Posted January 26, 2004 Report Posted January 26, 2004 I note that torque from 130bhp and 115bhp models are virtually the same. It might not be too long before insurance accident examiners start checking for these gadgets I reckon... Also lots of people say that the 1.9 is designed for much higher output - urban myth methinks. :D The reason manufacturers dont up the output is because of insurance and eco reasons. Thats why not many people bought Sierra Cosworths...try a get an insurance quote on a 190bhp Sharan... Quote
Guest shararnman Posted January 26, 2004 Report Posted January 26, 2004 Hi everyone, RMTONKINS is correct in his assumption that moving the fuel map will cause a loss somewhere in the system, looking at my rolling road graphs; in standard form the torque curve is smooth with the tanget from any adjacent point curve changing everso slowly (the cars smooth to drive): with the box fitted the curve takes on a more aggresive profile, the torque curve gradient is steeper upto 2000 rpm and then levels off contining to rise at 2200 rpm, a noticeable flat spot is apprent at 2000 rpm, the technique is to drive through this spot, however the downside is that if you hapen to drive everywhere at 2000 rpm then this product id not for you. As an aside the 1.9 tdi crankshaft is certified for approx 200 bhp; also my insurance company was informed, a small increase in premium; my alloy wheels on my FOCUS hiked the premium more!! however if you do not tell youe insurance company your very silly, on the emissions front the CAT A test results for my car a within .05m -1 fitted/not fitted.

Guest Turbo Posted January 26, 2004 Report Posted January 26, 2004 Let`s face it, manufacturers could put a lot more power to the driven wheels if they wanted, but they do have to find a happy medium. Fuel consumption, engine stress etc all have to be considered. Increase the turbo boost too much and the chances are you will blow the head gasket or maybe even crack the cyl. head itself. Maybe you`ll knock the bottom end to bits.Do you want something that`ll last 70,000 miles or over 200,000 ( hopefully )? It`s the same if you re-map the ECU- you are putting more stress on everything. With our cars ( and I`m talking more diesel here) VW have designed an engine to run safely and reliably at a set power. Yes, ok you can buy 150bhp Golf TDI`s etc, but they are set up at VW properly these engines. Maybe a 150bhp model will become available. Me, I wouldn`t fit a "chip" ( I`ve got enough of them in the bonnet !! ) especially with 168,000 miles on the clock, but it`s up to the individual isn`t it ? I have heard that you do get more acceleration higher up the rev range but low down performance is poor, or not as good, so if you`re like me and change gear at no more than 3000 revs you would probably be worse off.

seatkid Posted January 26, 2004 Report Posted January 26, 2004 I believe by euro law, the manufacturer has to ensure certified emission limits are maintained for the lifetime of the vehicle. And where can we see the evidence the 1.9 tdi crankshaft is certified for approx 200 bhp? When VW fetch out a higher rated variant, many components are changed and uprated for instance the cylinder heads and valve gear use more exotic material e.g. sodium filled exhaust valves. You're not telling me I can take a bog standard 90hp vintage 1995 and chip it to 190bhp without trouble. And what about the rest of the car? Gearbox, brakes, etc. If your insurance company accepted it for a small increase in premium, you have been very lucky indeed. Quote
Ivor_E_Tower Posted January 26, 2004 Report Posted January 26, 2004 Think you'll find that the PD TDI 150 engine is available in some european countries. From reading comparative tests on the VW Golf, Turbo is right, that engine is criticised for not having as smooth a power delivery as the 130 or 115. I seem to remember reading that it is also harsher - less refined, more vibration but this could be down to the installation.Now a 2.5 V6 turbodiesel, or even the V10 from the Toureg........... Quote
seatkid Posted January 26, 2004 Report Posted January 26, 2004 Looks like the 1.9 has reached the end of the line - notice all new Audis and VW are now getting the 2.0 litre diesel which is supposed to be streets ahead in refinement etc. and also meets the latest Euro IV standards Wonder when the Shalalaxy is getting it?

Guest reefer Posted January 26, 2004 Report Posted January 26, 2004 To add my two penneth, surely you should advise your insurance company if you fit a "chip", because the vehicle isn't standard anymore. Then of course your premium goes sky high !.Not worth the hassle I think. Stick with the manufacturers settings. Quote
Guest SA Intruder Posted January 26, 2004 Report Posted January 26, 2004 The 130 is less refined than the 115 in this application. My experience of the 150 Golf is that it is very vibration prone at mid revs (those you cruise at). The 130 is really awful at 80 mph in top, and it gets worse with mileage... The 150 will not find its way in this model of Shalaxy; it has run its course. Quote
