Just thought I'd share my recent experience after getting a flash tune on my N Line.

I had initially intended to install a Racechip RS but after waiting 5 weeks after ordering (due to delays from the Aus distributor) I cancelled my order and ended up getting a flash tune instead through Cherry Tunings & Performance based in North Parramatta.

The car is reasonably stock, only changes are a K&N panel filter, intercooler resonator delete and the second cat and resonator deleted on the exhaust. There's potential to get more out of it with a proper intake and maybe a couple other little tweaks but being that it's predominantly a commute car I wasn't really looking to chase too much additional power over stock.

There's some decent difference to the power output and delivery and I'm loving the exhaust pops on deceleration. It feels meatier on the low end and power delivery is more linear and smoother through the whole rev range now.

The only thing I'd look at doing to the car after the tune is the pitch mount bushings because there's some serious axle tramp in the wet now. Apart from that it's near perfect for me.... for now

Hmm - thought I'd already replied to this.

Do you have any dyno sheets with the before and after?

Please share

Cherry only supply the information listed on their website 1.6 T-GDI ECU Flash

160kw at the front wheels would be roughly a 20 - 25kw gain.

Makes the Racechip GTS good value Racechip GTS - Top-Level Hardware Tuning Solution 37kw at 116Nm

Hmmm, seems a bit odd to me that there are not any dyno sheets available.
Perhaps they have them from test vehicles but personally I'd like to see something as opposed to a 'seat of the pants' reading.

Hoping to get the car on a dyno for some power runs in the next couple months and will definitely share the results when I do.

Have you lost the factory warranty?

Have you lost the factory warranty?

Writing directly to the ECU is generally the safer bet and shouldn't be detectable, though technically if discovered you would lose the engine warranty but Hyundai would need to have the files open side by side against an unmodified ECU to spot the difference.

There is also the possibility that Hyundai might try to update some of the changed files at a later date which they will receive an error/cannot write file message due to modified file being code locked via whoever modified the files.

Would be interesting to know the maximum power & torque rating for the DCT  fitted to the n-line/sr, and would modifying the 1.6T ecu parameters to produce more power shorten the lifespan of the aforementioned transmission and/or motor, not to mention potential voiding of warranty.
Maybe some knowledgeable person can answer this?

I can't comment on the maximum torque the box will handle, that would require a Hyundai transmission engineer for that answer I'd expect

As far as warranty is concerned with ECU tuning...if detected then you have no warranty.

That is definitely a legitimate concern as it has taken 2 years + for Hyundai to come up with a DCT (now 8 speeds and wet clutch, not dry as in the N-line) that will cope with the extra torque of the i30N. I don't think I would be enough to try a flash tune on a DCT N-line for that reason. A manual N-line maybe..

A bit of info in the linked article, 1st and 2nd are on the same shaft unlike VW which also explains why the car isn't quite as zippy off the mark, but on the other hand it is proving a little more reliable!
