Polo GTI ECU flash done...

[GTI JOE]

My comment about confusion was mainly aimed at the 77TSI comments. To answer DoggieHowser's question, yes, it can be.

As for the quote from John you put in red. I've seen that. As I said in my post, I'm happy for John (of DNA tuning) to correct me. But if a car cannot be flashed via the ODB port, as per way's Polo GTI, then I'm not sure what good a hand held unit would be.

Again... to clarify, I'm not saying that the SRS-II won't work on any Polo GTI. I'm just saying that if companies with professional ODB tuning hardware need to remove the ECU on specific Polo GTI's to bench flash them, then I don't believe the hand-held units will work on these specific Polo GTI's either (and they certainly haven't from any other brand in the past either).

Although I have had my disagreements with Corey in the past, on this occasion he is correct, unfortunately........for you and I
At the moment I do not believe that there is a hand held unit that will work on the OBD port, yes, even DNA, they will have to do the bench flash like APR. Other tuners, such as Viezu etc. are encountering the same problem, which is a real shame. I'm sure someone very shortly will come up with a hack...errrrr fix that will enable it, there's always someone

I also hope John will be able to participate in the discussion.

[DoggieHowser]

I've used a Cobbs device on an R35. Pretty nifty. Even gives me error logs.

So the 77TSI requires removing the ECU?

Viezu

Yeah guys - unfortunately our first GTi POLO 1.4 twin charger we had lined up here in Aus via V-Switch (same unit as the SRS-II John uses at DNA) was a no-go. The V-Switch can't read it for whatever reason. It doesn't necessarily mean it's anti tune (and therefore has to be a bench tune job) - the V-Switch units sometimes can't cope with certain ECU's that's all. Good news is there's a new V-Switch coming out later this year which is more powerful and will be able to work on more vehicles... until then...

In addition - a brand new Golf (VI) GTi had the same problem last week. The Golf Mark 5 GTi is awesome - and we can do the new Golf 'R', 118TSI - etc via V-Switch - but there are certain models which will always give the remote tuning units a head ache ...

Will keep you all posted

We're working on it .....

Thanks for educating me guys, never heard of bench flashing until this thread. So tell me, is there any disadvantage of bench flashing other than obviously having to take the ECU out?

[Corey_R]

Takes long, equipment is more expensive, you have to take the ECU out etc. There are no advantages, other than allowing you to flash the ECU when the regular methods don't work. So if it's possible to simply do it via the ODB port, then you'd do it that way

Bench flashing only required when the ecu is anti tune like some of the new MED17 ones. It's not really desired or beneficial exactly - OBDII tuning is easier and can utilise remote tuning devices like blue fin, srsII and V-Switch etc...

bench tuning uses the same mod mapping...

[GTI JOE]

..............also, depending on how it's bench flashed/tuned, you may not get any selectable tuning. That is, new performance tune over writes your stock and you are stuck with it. As far as I know, APR is the only company that can give you this selectability, I hope I am wrong, but I have not read anything to the contrary

[Mike]

YES!!! APR are having a Winter sale with 15% off ECU tunes.
I was so bumbed that i missed out on the EOFY sale, but i should have my car next week so i will definitely be taking this up!
Just unsure whether to go to Volkspower in Burwood or Melbourne Performance Center in Bayswater.
I work in Bayswater but i've heard MPC aren't the best and haven't really heard much about Volkspower though...

It's probably a good idea to drive the car around for a few thousand kms before pursuing an ECU upgrade; if not for the sake of ironing out any potential faults/bugs but so that you can really compare the benefits of the tune.

I'll be following this advice

[Gambit]

Cant be bothered going back and reading everything, but can anyone tell me, is the tune just a generic one, or is it dyno tuned to suit each vehicle that gets flashed? ie. will be running a K&N airfilter and wondering whether that can be accommodated to get more power out of it when tuned on a dyno?

[Corey_R]

APR, GIAC, REVO, Oettinger, Bluefin, Superchips, Custom Code (all the "brand names") are "off the shelf" tunes. Though, as per many modern cars, the tunes are "adaptable" somewhat by the ECU.

To be honest with you. Changing your airfilter does zilch. No one has ever "shown" improvements (via dyno etc) on a VAG car from changing the filter. Changing the entire intake is another story...

The name brand tunes are adaptable enough to account for most intake changes on the Golf's at least. Since there aren't any available intakes for the Polo GTI at this stage, I'm not sure what the situation is.

You of course can get a custom-written tune on a dyno. Go to a boutique tuner instead of a name brand one.

On the basis that the car manufacturer puts one 'tune' on a particular ecu for a particular ecu / model - tuners do the same to a large extent. We'll get a model - prepare and test maps for it on the dyno - then launch it for sale as whatever tune it is - Max Eco, blend, Performance, Max Torque, Motorsport, Race Team etc etc.

So the tune will be whatever you want it to be - certainly in the case of Viezu.

There is not need to mod a file for small modifications such as and sports filter as the ECU will cope and perfectly adapt 8% on induction and 11% on exhaust. Sometimes when there are a lot of bulk mods then it's an idea to get a bespoke tune but - and I hope I speak for all tuners - we can take account of such things very easily when supplying the map file if required and do so all the time.

Sports filters have different affects on different cars. Some just get noisier induction roar giving the placebo of speed. Most can give better responsiveness making it feel quicker and you'll see very small gains if you're lucky depending on the vehicle.

Hope that helps

thats a fair enough response re: airfilter and a generic map and its ability to take into account the variation...

Just coming from the world of Open ECU tunes, you pay $800~ for a tune thats done on a dyno, bespoke and specific to your vehicle, your able to go into it afterwards to Log and check all tuning parameters with an OBDII port cable and Romraider and take it to another tuner for whatever reason later on if you choose, and get it ECUFlashed again for further fine tuning at whatever hourly rate they charge.

A case in point with my Subaru, the previous owner had an Ecutek generic map/tune on it, that was locked, in order for another tuner to dyno tune it, i had to get it sent to chiptorque and wipe the ECU and reload an OEM map back on so that i could get it Open sourced tuned. So i have my reservations.
