Hi All,

I am thinking of optimising the ECU software of my 2.0l T-FSI VW EOS which would increase the bhp from 200 to 240 and the torque from 280 to 350. It would be done by a company called Race-Tune based in Slough in the UK. I was wondering whether anyone has used them before and would have nice or bad things to say about them. Or alternatively if they could recommend another company they were chuffed with. How about services at a main dealership, would they notice it? How about car insurance? Is the whole thing a good or bad idea? For those of you who have already done it, have you really noticed an improvement in the fuel consumption?

Thanks in advance for your feedbacks.

Kind regards,

:confused:

I had the APR 98 octane ECU and the Carbonio air intake fitted. It takes the car from 147kw to 195kw. best way to describe it.....AWESOME!!!!!!
heaps more power, particularly at the low end. very little throttle or turbo lag.
fuel consumption is similar, however I tend to 'play' a bit more and use a little more when doing so. the product is switchable between standard (for dealer service) and the ugrade. fuel is a bit more expensive as you can only use 98 octane.
The cost for me was around AUD$2400 and worth every cent. I did the upgrade 6 weeks after getting the car new - it does avoid dealer warranty if it causes any faults, technically you have to advise your insurance company as well

Thanks Cappers for your feedbacks. I have just found out that my insurance company would not touch me if I was to go for this ECU upgrade. So, I might have to shop around and approach some specialist insurance companies. The thing is, I probably won't be able to find the same sort of good deal as it is a niche market. Another thing you have mentioned is that the product is switchable. I need to check that it is the case. I don't also understand as to why VW don't do those types of upgrades themselves. They have the technology and there is a demand for it. And as for the fuel, I already buy the super unleaded @ 98 octane, so no changes there.

There are several reputable ECU tuners out there, but I'm familiar with APR and like Cappers can vouch for their Stage I tune. The ECU programming is easily switchable via the cruise stalk, so you can return it to stock settings for dealer visits (if your car is still under warranty). There's really no way the dealer can detect anything if you lock out the programming. As to why you'd want to tell your insurance company, that must be a UK thing! ;)

Stage I is fairly mild tune & we don't abuse the car, so I don't expect any problems. APR is a well-established company, and they work on VW factory cars.

Thanks Lucid Nonsense for your reply. You're certainly not the first person to mention about APR. I will check them out. I don't think that wanting to tell my insurance company is a UK thing. You just want to make sure that whatever company you are insured with will not walk away from a claim without settling it because they have discovered that your ECU has been modified. But that's just my take on it.

Dealership awareness

My friend a mechanic at the VW dealership said there is a counter on the CAN Bus connection, that is read of when they connect the service computer. So if the counter doesn't match with the number of services some reasonable technical guy or company has connected to the cars computer! And there is only one thing that comes to his mind..... Chip tuning...

That's interesting, but I'm not sure how a CAN Bus counter would be of value to VW in trying to track down potential chip tuning and deny warranty claims. I'm on our car's CAN Bus every so often with VAG-COM, and the dealer hasn't said anything during service visits. VAG-COM duplicates the last Work Shop Code (or it enters something innocuous) if you change any settings. Not sure how APR and other vendors address the ECU during software upgrades, but presumably they've thought about being stealthy as well.

IMHO the key thing is to avoid visible mods while you're under warranty. There's no rash of warranty denials for Stage I software that I'm aware of. Blow up your motor with a fat downpipe, K04 turbo, etc. installed, and VW may have a slight issue!

took mine in for a scheduled service a couple of weeks ago - set the chip to standard, however as I have a Carbonio air intake fitted its obvious I have had some mods done. VW can only void warranty if the mod is proven to have caused the problem - not simply because you have a modification. My dealer actually suggested the chip upgrade when I asked about getting more power BEFORE I had it done. No comments were made by the dealer about the mods after service
