Test drive update :-

Fitted the tuning box yesterday afternoon and jafter that I started the car up to make sure no issues with it, all was fine

Took the car out for a 30 min drive just now

The preset power setting appears to be just right (the box has 15 power settings and its currently set on 11/15), torque comes in nice and strongly at about 1900rpm, then it just seems to hold its power nicely until around 5000rpm, performance wise it feels much stronger than the previous racechip one

I can give it the thumbs up, however, is it worth £125 more than the racechip one ? if I had paid full price for it £229, then I think I would stick with the racechip one, but seeing as it was discounted, then I am think its a noticeable stepup performance wise from the one and worth the extra £80 I paid for it

Nice write up. Sounds like it was money well spent.

I've removed my racechip from the car for the meantime. After the factory software update,  it just  didn't seem quite as effective as it was before the update. I also noticed that the mpg read out with the Racechip became widely optimistic after the software update.  Previously it would have been 2 or 3 mpg out but this had become like 10-12 mpg out which is a little annoying in my world.

The other thing I noticed is that the engine appeared to be a little highly strung (pulsing,  noisy) even when idling with the Racechip. This wasn't as obvious previously. It is really smooth and responsive after the software update.

So,  I'm thinking of going the remap route but I am a little hesitant with the local company that does them. I'll give them a call anyway to see if I get a warm fuzzy felling.    Not too many options around here.

I didnt really notice any difference with my car after it had its latest software updates

I did notice a somewhat erratic idle just like you mentioned with the r/c box, the new box seems fine, idle nice and steady

The r/c read about 5-6mpg over on my car, havent really had a chance to notice with the new one, will keep an eye on it, although I did manage to see 9mpg at one point today (on the instant readout, not as an average!)

the only options for me locally are superchips and quantum, both of which are over double the price of the latest tuning box, I dont mind spending a few hundred, but, baulk at nearly £500

Good luck with your repair tomorrow

Good write up.

I have just been on there website having a poke around to see what they are claiming and I like the fact they have dynographs of the cars but I do wonder if they have done this on an actual car or if its just made up.

I am looking at fitting one of these types of chips myself or even a remap so I like see other options.

Keep updating with how you are getting on with it fitted as with everything it can be fine for a month or so before issues can arise.

I have looked at the dyno print out and it didnt really make a lot of sense to me

What I would have expected is a pretty flat torque curve, then a tail off (which it does)

However, the power plot, where I would have expected a gentle rise over the rev range, appears to be a straight line of about 220bhp for over 2000rpm, I have certainly never seen a power "curve" plot like that with rolling road results 

Am I right in thinking that German tuning companies have to have TUV approval and therefore the results have to be "proven" rather than stick a finger in the air !
