[Field Marshal Dr. Opti]

I almost sold the Tata last week but changed my mind at the last moment.

Yesterday, my new toy arrived and the difference it has made to the performance is more than I was expecting. Price of the unit is £599 plus VAT, so £718.80. I negotiated a price of £450 including P&P.

Zero to sixty in 4 seconds is no better  with a lack of traction being the main problem. However, once rolling the car is far quicker than before even though it wasn't exactly tardy to begin with.

This application works extremely well with planet-killing derv cars.

If you fitted it yourself, I take it it's simple. They reckon they can squeeze an extra 40bhp out of my astra, taking it to over 200. Only £249+VAT.

It would need to be.

Yes......pretty simple to fit. They send a new map by email. In the old days it would have been cams, pistons and carbs. Now it is some geeky kid who sits in front of a computer all day.

So you bought the V switch? Just been speaking to a nice chap called Ian who explained it all to me. I was a bit worried about 205bhp through my auto box, but he says it's ok. I'll give it some thought, 205bhp may be nothing to you, but it will certainly pep up my dog walks

It's not just the extra power you'll notice but the extra torque.

Ask for a discount they will almost certainly give you one.

V switch is £299+VAT, they will let me off with the VAT (£60). I'll have a ponder.

Dr Opti,

I have some magic beans here. £500, but you can have them for £250 cash. 


Seriously though, how did you apply the map if it was emailed? Not sure a 5.0 Supercharged V8, with 0-60 if 4s needs more power. 

[Varche]

 V switch drive ?

Quite an interesting read. I like the concept of valet mode!

So do you buy some hardware which can move from vehicle to vehicle and then the software for your specific vehicle?

It's quite simple really. Using the V-switch device supplied by Viezu, you plug this into the car and download the original map to the device. This file is then transferred to your computer which is then sent by email to Viezu. They then send you an uprated map, which you then transfer to the V-switch device and you then plug into the car and upload. Takes about 20 minutes each time.

Surprised a 3rd party tool is allowed write access to such a critical component as engine map, you would have thought Jag would have locked that down for you average DIY'er

Basically, yes.

Once you have the V Switch device you can access maps for the same car, or different cars, for about £100 each.

Remappers get around this easily enough.

Apparently Viezu remapped 24000 BT vans  for extra economy, and saved BT a fortune.

True, but in a garage full of tech, not home DIY tool.

I'm a bit sceptical of these maps to be honest.

I only plug it in and push a few buttons. It is not something I personally knocked up in a shed.

They say I can get an extra 45bhp for my Mondeo or alternatively an extra 20 bhp and 10% fuel saving. I think I have that right?
