Your three closest are TDP in southern Ireland, TDi North in Warrington (England) and ourselves in East Kilbride (just south of Glasgow, Scotland)

It's also worth adding into the mix that not all dyno's are the same, some are a pure inertia dyno, some have retarders. Mapping on the road can have it's flaws too, what if you tune it on a nice flat straight and then the driver goes up a hill causing the ECU to hit load sites that weren't seen during tuning? As a dyno owner/operator/tuner I have seen the pro's and con's of dyno Vs Road tunes. As someone has said you can have everything set up sweet as a nut on the dyno and then hit the road and the boost can over shoot quite easily if not set right, that's why a road test is always advised after a dyno session. This is a bit difficult for track cars but that's why a lot of tuners will offer track side support to review the data from on-board loggers (where available). All of the hard work will have already been done, timing will be optimised, fuelling will be correct, it's just the real world behaviour of the turbo that can be an unknown, which is probably why some operators will hold it back slightly, making the car feel less responsive. When road tuning unless you have a huge wealth of experience and/or are dealing with a knock limited engine there is no way to know if you've truly got the timing right, this is where dyno's with retarders come into their own (and inertia dyno's fail), the ability to hold the engine at a set RPM point whilst the operator optimises the timing is a phenomenal tool. Back on topic, Uprev is just a software like ECUTEK, the owners are protecting their investment and recouping their costs by having a licence, this way they can continue to pay their staff to improve their products. The ability to remap the OEM ECU can be done using other tools but to edit the file you're best to know hexadecimal code to understand the data before making changes, I for one am not a software engineer which is why I pay for products like Uprev to allow me to do what I know what to do.

Rates are £30+vat per hour for garage time, this will be going up to £35+vat in April. Dyno time is £55+vat per hour and again in April this will be going up to £60+vat in April. Geometry is not something I do at all, I use either Kenny Brown or Automek as they specialise in that area

Was it a red Scottish SCd 370Z? If so the normal belt for a Stillen kit doesn't fit as the original owner fitted an extra idler to get around a belt slip issue.

Sorry for the shameless plug but we're in as well ;-) it's not just tuning we do but also all servicing, repairs and modifications

Not to mention the near zero chance of it coming off in the first place, zero chance of a strap breaking and the car getting loose, zero chance of a tyre failure or loss of traction etc etc Thanks for all the kind comments

Looks likes Simon has done another great job for you Paul, can't wait to see it in the sun.

I think a bit more information is needed here, here's a copy of the power, after the plenum spacer was fitted, before and after tuning: As I explained on the day you can see the first run netted 233bhp@the hubs, down considerably on the original 248 bhp, this could have been due to a number of reasons, fuel choice in particular. After tuning it gained 17bhp @ the hubs. I can't remember for certain what fuel was used for the original tune but for this one Nissanjuke confirmed it was standard supermarket petrol (95RON), although it only gained 2bhp over the last power figures on the day it gained 17bhp.

That took you a while 'not to modify this one' can't wait to see what you do with this one

Still an impressive amount raised

Gutted I missed this year, I've been the last 2 years with the Soarer that had 'Link' and 'Diemax' on the sides. how was it?

Welcome back Paul, a bit shocked at getting rid of the GTR so fast, but then you can't live in your car, comfortably

The check light was only switched off for the de-cats, nothing else. If you pop by as discussed via PM we can get a real reason as to why it's on instead of wild guesses

Hi Raymond, We are doing an introductory offer and it's including VAT once the offer finishes we will be in the same price range as every other dealer in the UK

The revving out of the engine is directly related to a few things but mainly it's down to bhp, so long as there's no issues with the car causing the lack of power then suitable modifications and a map to suit will help

So every time you map a car you have to pay this? Every time I get a standard Z I need to use a licence to let me use Uprev to tune the car, if the car already has a licence on the ECU then the fee has been paid and the only cost to the customer is what I charge, it's not free money tho as it appears, there are other costs involved in running a dyno, 3-phase fans etc chew through electricity, water to cool the dyno is another cost too, rent, rates, taxes, wages etc etc. Once you break down the numbers there isn't a huge amount left at the end

Hi Octet, at the current exchange rate the license cost is $300USD which works out at just a shade under £240, usually this will be rounded up to £250 to cover admin and hope the exchange rate doesn't cause them to need to raise the prices. This. Its not a lot, you get a 'feeling' that the car is quicker and more responsive but hey placebo and all that. It's not really a placebo effect when you compare the two graphs, what you'll find that although you gain 10-20bhp peak figures at the top end the gains in the mid range and low down is what makes it feel quicker and more responsive.

That does make a lot more sense, Uprev is more expensive because of the licence fee, the same as ECUTEK which is more common in the UK. As I said in my post I can't understand hexadecimal and so I need an interface, this is what Uprev have developed. If you think of it like Windows on a computer, software developers use Linux or something else which is free or you can pay for a Windows licence and you have a nice user friendly interface. The licence fee is Uprev reclaiming their research and development costs and earning a crust on top.

Every car is different so there's no one hard fast rule, the Evolution Chips map is a generic modification formula that's used which is why we've invested in becoming an Uprev pro-tuner. Even with this you can't give an average gain as each car is different, you could have one with a blown gasket and your average drops, is that a true representation of gains? Jetpilot, the reason you pay ' so much' to get a car mapped is the same reason you pay ' so much' for a wedding photographer or a performer to perform at an event or show

Well this is an interesting topic As Nissanjuke has explained, we are a dealer for Evolution chips. Why would a tuning company become a dealer for someone else and use their maps? Simple really, although I've been tuning cars for years, I have been using after market systems which put everything into clear and simple tables of what values change which parameter, when it comes to the decription of OEM ECU's all of the interfaces provide you with is thousands of lines of hexadecimal code with no markers, no axis' or it is shown as peaks and troughs in a line graph. I am a mechanic/engine calibrator, not a software engineer. I can't comment on what has happened with other Evolution dealers and their customers, as with any dealership each shop has it's own way of working and sets of circumstances, as it stands we have never had one customer return and ask to use the 30 day money back guarantee. Why would we look into becoming an Uprev pro-tuner when we have the facility to tune Z's already? As it is stated, the modifications to the files are generic and although they can be customised to suit requests it's a lot of down time and data logging rather than live custom tuning which is available using the Uprev interface. We have our own Dynapack DAQ5 hub dyno which allows us complete control over cars when they are being data logged/tuned in solid state or dynamic cycles. As there is clearly a demand for Uprev north of the border we recently returned into discussions with Uprev and are now Scotland's first Uprev pro-tuner.
