Hey bros, I need your help... I'll be getting a koup beginning next year if all goes well, and I want one that I can mod and take to the track I was originally planning for the 2L manual, but lately, thanks to 2 guity parties (you know who you are) I've been considering the 1.6M, mostly because of the drive by wire
can you all help me list the for and against for both 2L and 1.6L? thanks a lot I'll start with what I know so far
2L - for: more power
Against: e-throttle (slow response) COE price (very ouch)
1.6L - For: drive by wire (better response) COE price (less ouch)
anything else?

Theoritically, the e throttle retarded response can be solved by tuning with unichip. It works because the ecu can be made to believe it is full throttle when say only 40% throttle.
If I were you i would get the 2 litre for sure. I think the new version koup is coming out right? Maybe wait longer abit.

thanks for the info bro I heard tho that the unichip also causes the throttle to not rev down during gear shifting or something the like... Yeah hopefully when I'm back in January (going away for a month) the new koup will be out...

no prob. the new koup looks delicious. u shld really wait. About not rev down during shifting, i am pretty sure it can be done w unichip but never c ppl do before. But alternatively, u can achieve the same thing by not releasing ur acclerator when u down shift gear too.

I don't think the unichip can settle the downshift rev problem of the koup e-throttle.
-- It is due to the response and TPS that the e-throttle have this retart rev when trying to rev up... and when slow down to down shift for Manual, the rev also retart itself from reving down, thus when u try to down-shift, you might have either too much engine braking or too little, thus hard to control your exit speed from any corners..

Bro normally is too mch engine braking, I did that in the track before wow

Now that we have learn to adjust the TPS, i think E-throttle is not realli an issue anymore..

www.sprintboostersales.com/whyitworks.cfmFiat uses sprintbooster for their e-throttle. I believe there are market equivalents for the koup, in fact every make that uses e-throttle. its just an electrical speed demand output. the booster just amplifies your throttle signal, ie degree of depression physicall convert into signal --> booster, amplified proportionately and faster response time. Industrial speed demand inputs go by 4 - 20mA , but when the physical action is done, there is a slight delay to convert the angle of depression input mA to output. ie when u step, u dont immediately go. a typical sprintbooster shortens the delay, and increases the magnitude of that output. therefore without any modifications, when you release ur pedal, there is no input , it will experience retardation via engine brake as per normal, though from a slightly higher rpm than without booster. Note there will be jerkiness if the right foot isnt controlled well. it is more 'delicate' in this sense. the butt dyno effect lets the driver think it is 'faster', but actually when u lightly tap on the pedal, in actual fact u are maybe halfway or fully pedalled compared to without the booster. dont worry about the max output. it is controlled by the ECU and no more injection will take place when it hits the maximum injection quantity curve. P.S. e-throttle is also known as drive-by-wire

next comes which car to buy? the differences: - Nov COE $39k and $47k for Cat A and B. both are ridiculously high, but if u willing to pay this, Cat B seems just $8k away. - However, do note your increased road tax every year which is fixed. Your insurance will be rather high as well. - AT and MT is a large difference due to 5/4 speed. even the reviews say so. - 2.0M 156bhp is much faster to track than a 1.6M 124bhp. You will have a much higher torque on a slightly heavier body. Then again you want to race against 1.6 SOHC/DOHC or V6 cars, makes a difference. due to less weight than the forte, the century sprint for 1.6M is about the same as variant 2 1.6M. - Fuel consumption: if the 2.0M really pulls >12.0km/l in mixed driving, i would be highly poisoned as well. This should not be your area of concern, just mine

P.S. e-throttle is also known as drive-by-wire Bro, what you say is rite but do you know there is a problem. In Singapore or so far there is no adapter for Koup e-throttle yet we have checking around the only way to do it is to cut wire. That will cause WTY game over.

if that's the case, pls delete my earlier post LOL.
can't be too hasty ba. do major mods which can be achieved by future minor mods sometimes is a squeeze ball feeling.

Like Honda is differe they have V-tec can get easy 30bhp just enjoy the ride.

unichip governs alot more paremeters than just speed demand. its good if u already want a partial upgrade on software and improve on ratios and whatnot. but i wouldnt say it works exactly the same way, the logarithm is maybe different.
sprintbooster dont give extra horses but reacts faster and on higher magnitude. so u can perform closer to paper spec thats all. unichip etc is to exceed it.
