Rs chip

[koolaid]

For me i keep my cars stock. If i want a fast car, I'll buy a gtr.

Likely yes. Using a standard set of settings can't give that much... but 10% is rather high... after I did mine, I also forgot the figures, but I wasn't going for HP increase.

I was going for other factors like pick up, torque, AFR etc. Singapore HP high no use, can't run fast also.

Wats afr?.....

Typically there are 3 type of solution , Piggyback ,Reflash and standalone

Piggyback-> Running in parallel with Stock ecu, hijacking stock signal control.
Dont provide as refined control , only use it if you have no other solution. Some ecu will get confuse by this external hijacking controller and get into protection mode (that is the time you feel the car weird or not as powerful as before ). Not all will have this problem but quality vary greatly.

RS chip is piggyback. It is a dummy , no brainer solution, Workshop/tuner only taking care of installing it ..there is no custom control. As such, it may gain some power but not optimized to cater for error margin.


Standalone- very Costly but definitely good for high power tuning, however it has the drawback of not refined and rough other area of control beside power. idling, aircond, load switching...

Reflash- this is the best, all rounder solution, that re-used back stock control scheme, retains knock/safety control. Tuner only focus adjusting the power gain tuning . You will have smooth drive like stock on normal cruising and mad output on full throttle. I advise users to use this solution as much as possible for safety and fun balance.


Custom tuning is not a snake oil.
Custom tune do gain more power than stock. .A lot of time,due to marketing purpose , you wont see manufacturer one time set to ultimate high power despite the Engine can withstand the power output.
in simple term, the power is not tuned to max out the hardware capability.

Technically. controlling these 3 parameters
1,Air/fuel ratio
2. Igniton timing -when to spark,
3.Boost-how much air to clamp to the engine per combustion cycle.

Advanced
- Intake/exhaust CAM.. - After changing to more freeflow exhaust, this must be tuned to compensate the lack of back pressure to gain back the low end response .


Above is not hearsay but personal practical hand-on experience.

Actually, piggybacks are suited for cars that have no options to tune the ECU directly. As the ECUs cannot be tuned, piggybacks like Unichip/RS is used to override the ECU settings.

For reflash, they basically take some SAME standard mappings and load it into every same model, it would optimize some settings based on road conditions & car, but it's still far from being optimized. Since every car is built differently (even same model), reflash doesn't bring out the best, just some parts only. Eg: FD1 global map, vs FD1 racing map, vs FD1 Europe map etc etc.. it's still by a 'category'.

For ECU tuning, for cars which are able to be done so, is by extracting the existing ECU map, study it, and optimize the map before flashing it back. This is the optimized version, which best suits the car and the road driving conditions.

When you do all these, if you don't know what gains you are looking for, it's quite pointless to monkey see, monkey do. People often talk about CAI, decat, open pod etc... GOOD GOOD MUST DO VERY GOOD...

But mostly.. don't even know what gains they are talking about. Just blind following won't help.

If you don't know what you're doing, best is stay stock. I'm not a guru, but I've done a fair bit of mods myself, including ECU remap for my current Maz3. My last car Vios can only do piggyback, which I don't want to, but now NCP93 can do reflash liao.

Dyno is when you have done at least Stage1 (IMHO), the gains won't be fantastic like ECU remap, about 3-5%?

So different strokes for different people.

Don't think optimize is right word to use. It sound like manufacturing do not have the skill to setup a profile that matches best for the car.

Remap is just to shift the map base on "feel" or "need". You probably gain one loss another.

Job creation for tuners mah... lolx.... even computers also have tuners.
I dun think manufacturers can't do the job of those tuners.

I would say optimize because the settings are very generic for normal road use, it's like you buy a PC, mobo, ram, cpu, etc.. you will no doubt want to tweak the BIOS to make the system run as desired. That's optimization.

They have the skill to do it for every car, but as no 2 bolts and nuts are built the same, every car requires different tuning in a way, so they just use a standard profile, flash it in.

That's why when I say reflash, it depends on the tuner, if they are doing the same, using 1 setting then flash across all cars, or they dissect the options, optimize it based on other readings then flash it back.

No two engines are built the same.

Huh. Those manufacturers make millions of profit and they can't match those custom tunners who earn way less than them.
It is more like manufacturers have the skills and the expertise but they choose to tune the car more for fuel efficient or other objective than to maximum the full potential of the car.
Japanese are known to be very conservative therfore their car are tune the same way too.
