In an effort to save money,i am selling the Octavia vRs and optoing back in to my co car scheme with a vRS (due to 30k p/a miles and a company that will let me trade down) so i need a remap that can't be detected in the ECU code

i have heard Revo as an example have their name in the map

ps note to regulars-if you didnt want to be bored by reading another repeat thread,you should have ignored the title,oops too late!.Still,if you insist on entering every thread to beat your chest then fait enough,but i must warn you i am immune to such displays of male testosterone

They are all detectable, but saying that it depends what you mean. AmD opens the ecu to change the chip inside, but Revo, APR and now Jabba program via the obd port so although there will be no external sign that the engine has a remap someone with the right tools will be able to see it.

It is a shame the AmD one click doesnt yet work with the 1.8T petrol engine, because that would enable you to change the map between standard and remapped on the fly.

Tuning box or similar is the only way that is totally undetectable.

Isn't that what the Revo SP1(?) do too?

Even if they don't notice anything physically changed in the chip, they will notice a difference if they drive it!

Correct me if I'm wrong (James 2) but I'm sure that Revo switched off via SP1 is 'virtually' undetectable..whatever that means?

As Jon says though..tuning box is undetectable, assuming you've taken it off!

Is the REVO software downloaded into spare memory on the ECU and the SP unit is used to swap between standard and modified?

If this is so then it is detectable.

I believe the One Click is still detectable as is leaves something even though the code is "swapped in/out". Only for PDs though.

I had an error code once which refered to variations in Turbo running which poited directly to it possibly being "tweaked". Even if you remove the tuning box you will also need to clear the error codes with Vag Com before you take it in to be certain

As Manny said, they can all be detected if they really want to try

As far as I am aware with the revo sp1 it reads the flash memory of your ECU and stores it on the SP1 and uploads the map into the ECU memory.

When you switch the map off it removes the map from the ECU back onto the SP1 and puts the OE map back on.

Would be interesting to have a look with VAGCOM to see what can be seen.

That's how One-click works but not Revo. The code stays on the ECU and the SPS device just tells it which map to use from those stored. VAGCOM won't show anything abnormal. If set to stock mode the only way of telling is by doing a hex dump of the ECU. However most dealers don't even bother connecting the 1551 (which wouldn't show the remap) unless you complain of a problem. If you do have a problem your Revo dealer can reflash the ECU to standard.

HTH

I understood that once a ECU had been remapped evidence would be left. It just might be a case that the dealer wouldn't noticed but if skoda uk were to look into it. They would find something.

I'll ask our local dealer on thursday Andy, when mine goes in for it's first service. They do know about it.

Really interested to know for obvious reasons

Generally speaking, when reflashing an ECU to standard, will the ECU image used be Skoda's own, or will it be something similar to Skoda's own?

Just thinking, if a tuner is flashing with Skoda's map then they probably won't be licensed to do this...so they'll either be doing something dodgy in putting a genuine Skoda map in place, or they'll be putting a non-genuine (ie. detectable) one on?

Genuine question, I'm not making accusations...

If you do have ECU work done, somewhere there will be invoices for it, and it's pretty hard to get a remap done and argue that it hasn't been applied to a car...

Tuning boxes don't have this issue!

Problem for me with regards to a tuning box is that I have to open up that big metal flappy thing in front of the windscreen to get at it.

Think theirs something in the manual about that. Mention something about checking some fluids every now and then. Cobblers

You're pretty close to Tunit though - arguably one of the finest tuning box specialists in the land. If you pop over there and say you'd like to try one, they'll stick one in for you and set it up for you to try. If you like it, you hand over the cash, if you don't they'll remove it...

Be paying a trip JBS soon enough.

Do JBS do custom remaps or tuning boxes?

If you buy a tuning box is there not an invoice for that? :confused:

It's the map from your ECU so essentially you have the licence by owning the car. Anyway you aren't the one holding it, it's the tuner so why worry?

There is, but like I said, you can buy a tuning box and it can sit on your shelf unused - doing this with a remap is a bit trickier!

So it's easier to argue that a tuning box has never been fitted to a car...

It's never good when a company that's sold you a product has to cease trading because they've been investigated for piracy and received a hefty fine!

If there is nothing illegal about what they're doing, then it isn't a concern...just thought I'd ask though, as the cost of licensing an "aftermarket" remap is what most tuners argue makes a remap relatively expensive. So I assumed there'd be a cost involved with licencing the original map, unless they didn't bother or they didn't have to...

Guess where my compo money is going

The only way for a petrol one to be remapped with no fear of detection is to buy a second ECU and get it flashed with your standard settings (immobiliser code etc etc). You then get your second one mapped by whoever you chose. If it all goes tits up, you put the standard completely unmolested ECU back in.

Other than that, they can find traces of remaps, however hard you try to hide it. With my old one, they were going to take the ECU away to VAG technical for investigation.

With the diesel, an external box is undetectable, but other than that, you are back to the 2 ECU mallarky.

If this is too much hassle for you and you are worried about your warranty, DO NOT modify your car, it really is that simple. Sorry.

Isn't the standard ECU code encrpyted?
