Performance chip UPG - Too good to be true?

[tmx]

petrol is cheap again now thanks asda  

now we dont need to conserve it as much

[sev]

lol, is that right!

I'm old fashioned... i'd still like to see mid to high 20's!  (still she is carting around 2 tonnes plus!)

I also struggle to see how electronics can really bump up those figures, I'm still a believer in high compression, well gasflowed and valved normally aspirated engines to get power.

Electronics make massive differences..........it guarantess the correct fuel air mix, the right ignition point nad adjusts and maintains these optimum settings for the life of the engine.

This makes a big difference to economy!

[Jimbob]

Put a decent chip in.

Drive exactly the same.....you WILL get more economy

Drive harder, you will get more performance, but no worse economy  

They are Win / Win

[tmx]

fuel econmy is worse with my chip!

Not sure I agree with the drive harder bit - the MV6 can suck through significant amounts of petrol when I'm in the mood

Oh I appreciate that, but I'm talking about the monster power gains that chip manufacturers talk about.

Up to 10% is probably achievable but mapping fuel/ignition.

On turbocharged engines, there is far more scope for big increases.

sure, but from a plug in 50 quid chip?  it's a bit like when you dynojetted your bike, what you actually saw was throttle response and free breathing, and mistook it all for big power.

I need to get all my tables out to see what this 2.5 can really do with tickling!

Surely even fuel mapping to be effective really needs a good rolling road and a programmable ecu to maximise the potential?

Little horsepower costs big money, and big horsepower costs even bigger money! - that's what I remember!

Isn't that just then"Sport" button on the latest Vx's?  DIdn't notice any difference on an Astra SRi, bar sharper throttle response..didn't go any quicker overall!

Throttle response is deliberately damped in modern cars to help emissions, and, of course, it might make the engine feel more powerful, but it makes very little difference on  the road.

In addition, ignition timing is deliberately conservative (less so with the introduction of knock sensors) although an efficient engine shouldn't need to run hazardous levels of ignition advance anyway.

A little powern can be gained by mapping the engine with regard only to power output and not to emissions.

Remember the manufacturer has to get the car through type approval which involves everything that comes out of the exhaust from a cold start being analysed over a simulated test drive.

I would hope these chips have been developed on a rolling road - once you're down to getting the last few percent out of an engine you simply can't do it by "seat of the pants" but for 50 quid, who knows what you're getting?

And, ideally, you would get each engine set up on a rolling road because no two are the same. Not a difficult or expensive exercise if you have a mappable ECU, of course....

rolling road mapping is bloody expensive kevin ! for £50 for a chip i think its a bargain even if you get half of what they are qouting bud !   you are looking at £90ish an hour for live mapping !!  :-?

what do you want for a button ??

Preferably what it says on it...guess you can't polish a turd...

havin a ls1 V8 runnin on 4 cylinders till ya hit sport button would be a bit more fun
