Some early numbers but something is happening regarding i20N ecu tuning.
Numbers mean nothing. We need to see the shape of the powerband, plus some details concerning boost, ignition values, air fuel ration in accordance with rounds per minute, if you can change - expand the overboost function (lets say overboost from 2000-5000 rpms), move the rev limiter 200-300 rpms higher, cvvt changes etc. Just for the record, in my testings with racechip box car achieved 239,4 hp with 39,6 Nm of torgue.
Extensive Ecu tests - Real time data and Dyno
Hello to all members, I have made some extensive tests, which a part of them i will share on line, concerning the behavior of the I20N ECU and tuning data. The findings i am presenting here are backed up, by multiple Dynoruns, which happened, the same day, the same time, with the same fuel...

The graphs are in the instagram post, you've been constantly skeptical this entire thread, do you actually want the car tuning or do you just need to be right?Numbers mean nothing.

N75 motorsports have peaked overboost at 23 psi holding 14-16 psi at redline and the idle RPM is capable of being altered, the original calibration is read, it's just finding what each map does i.e. trying to create an A2L/Damos file
The post was only a teaser and that’s mentioned around 50 times in the reel.Numbers mean nothing.

Please don’t compare real ecu tuning and such boxes that fool the ecu with fake numbers.
BTW: MTT is well known for the highest numbers for i30N’s pretty much worldwide. I suppose we can expect much more from him.

I am sceptical because i have seen many ....crap files around From stock my 2024 car holds 13 psi at redline. Did you "dig" the binary code to find where in the hex address the revlimiter and the overboost "window" is implemented?
You've been skeptical this entire thread, not just about the files.I dont have instagram or facebook.
Cars will fluctuate engine to engine, i'm sure you know this. your car may peak at 13, another will peak higher, another may peak lower.
It's not me directly doing this, but the original calibration has been read by at least 4 companies already, it literally has to be there so the stock car knows what RPM to idle at.
that's what i'm trying to ask, they're seeing a huge loss at the wheels over standard hp, i wanna know what the corrected reading says, MT Tuning says 235hp 399nm on a totally stock car
Looking at the graphs stock it's 125.4kw which is roughly 168bhp at the wheels for us in the UK.
So a drivetrain loss of 36bhp, assuming a stock power figure of 204bhp.
164.1kw to bhp is around 220bhp at the wheels. So add the drivetrain loss to that and that is what you have as a rough figure at the fly - 256bhp. They did mention in their post that the car is running semi slick tyres and this may show lower numbers than normal due to traction loss on the dyno. The car has an exhaust and no other mods, it doesn't say if that's just a GPF back or turbo back system.
For me, it's the torque figures and curve that make the most difference. I'm not concerned with the peak bhp, it means very little in how the car drives. The torque between 2000rpm and 5000rpm looks to be a huge improvement over stock (100nm/73lb-ft) at peak) and that is what you will really notice. That's where the car spends most of it's time day to day driving.

There is no way with such a small turbo to achieve almost 270 ps with just an ecu reprogramming. That means with a good exhaust +vdownpipe and intake car would hit 300ps. I am not naive. The turbo is not capable of these numbers. For me its not the huge added torgue in the middle rps of the powerband that matters, because in a front wheel drive car, makes it undrivable for spiritual driving in b-roads. The perfect will be a modest increase in torgue at 2400-4400 and bigger gains from 5000 to the revlimiter. That is exactly what an upgrated - bigger turbo will do. It will leave the torgue almnost the same from 2400 - 4500 so car will be enjoyable through tight turns and when you exit the apex you will have power to accelerate from 4500 to redline.
cherry tuning are working on a bigger turbo now, there was already one available but it doesn't look particularly reliable or safe
Hyundai i20N Hybrid Turbo (53039880782), 3.867,52 €
Original, new BorgWarner turbocharger in various Stage power levels
I believe KTec racing (Renault specialists) are now getting the I20N upgrades inc this new remap
N75 motorsports released their flash map yesterday...
Anyone managed to get it flashed on yet?
Cherry have managed 275hp, 460nm on a "Stage 2" car, that's intercooler, downpipe, cat-back and intake and a tune to match the new airflow. the curve is basically the stock curve but raised across the board and torque staying higher longer with power peaking earlier.
MT Tuning in Germany have found the spark plugs will need changing and that the i30N spark plugs from NKS code M45XL are the right plugs to use, stage 1 from MT on a stock car 102 octane fuel managed 237ps, 406nm and a smooth curve with a huge torque gain across the range and with peak power coming on earlier and staying consistently higher.
The general complaint so far is the size of the turbo, It's basically the size of a tennis ball and doesn't like holding boost past 5k revs, redline boost tuned is about 15psi, this is also the reason that stock, the car seems to drop off massively towards the top end. But mid range numbers look awesome and day to day driving a remap is definitely going to be noticeable,
bye bye fiesta ST's, Polo GTI's lol
Thanks

Not exactly impressive considered a Mountune / Dreamscience + other tuned Fiesta/ Puma ST is around 240bhp on 98 ron fuel as a stage 1 - these cars are 1500cc 3 cylinder engines so I would have expected with an extra 100cc and an extra cylinder the I20Ns to show around 260bhp from a stage 1 tune
