hey saw some one selling tat in drift.com.my hahaha

Need to get good feedback from CPS user after using it before consider buying.

Hi guys,
I have been out from this forum for some time due to time constraint and I would like to add a little something regarding the top speed as I see that many have commented on this issue.
I have tried the top speed twice. First was daytime test on about a 3-4km stretch on the NKVE from the Bukit Raja interchange to the Setia Alam exit. Top speed - 190km/h. Second was a midnight test on the Elite highway from the USJ exit till the Putrajaya interchange. Top speed - 188-189km/h [ or thereabout as the needle hovered just below the 190 mark ]. Both tests were on level road. Totally disappointing outcome on both occasions if you ask me! I was expecting a higher reading on the night test due to the cooler air but it was not to be! Probably the xenon light took away a little of the engine power???
Anyway I personally do not think that there is any speed limiting device installed. I am not a highly technical person but I feel that something is wrong with the 5th gear [ probably the gearing ratio or something ]. There is plenty of kick in the 3rd and 4th but it all fizzles out in the fifth! I think many of you would agree that it just wouldn't do to have a 125hp engine churning out a top speed of just 190km/h!!
My car is still fully stock at the moment and I am seriously rethinking if I want to do anything to touch up the engine. Sorry guys to be so negative but fact is fact. My mileage is just over 6000km and I have driven the car for close to 2 months [mine is manual ]. This is my personal verdict for someone who is considering getting a CPS...
Pros...
- good handling
- good fuel consumption [ read one of my earlier posts ]
- good acceleration once it gets going but not on the 5th gear!
- comfortable seats for the price that we are paying
Cons..
- 190km/h top speed
- poor throttle response
- poor turning radius
- loud cabin noise
- engine buzzing sound at 2.5-3k rpm
Cheers!!!
I think they do not need to installed any speedcut, just programmed the ECU is enough as the throttle is control by electrical signal rather than mechanical (drive-by-wire, thus lowering the throttle response).

Probably you are right also, the best way is get a car (except CPS) and full rev at downhill then will know whether it suppose to increase or not
changing of air filter will eventually let the air to flow in more and faster since the ECU is controlling the throttle opening via MAP sensor. Meanwhile the O2 sensor will work parallel with MAP sensor to obtain as perfect (perfect is 14.7) as possible in A/F ratio. The better A/F ratio the better combustion and the better combustion the better power generates.
Actually the AFC Neo can't really work perfectly with campro ECU system, as the EMS700 is using emission control (ie, close loop). Furthermore AFC Neo can't control the Ignition timing and O2 sensor, therefore even we manage to alter the MAP sensor voltage then after awhile (about 3-4k rpm time) the ECU will reduce it back to preset setting with the feedback from O2 sensor.
But i still like AFC Neo

.
Already tried full throttle on downhill, RPM stuck at 5.2k.
Using better airfilter and plugs will improved combustion (tested

) but no effect on top speed, just easier to rev the car.
I don't know much about Neo, but if Campro's are closed loop system, there's not much it can do.

But AFAIK, Neo can 'fool' the ECU by giving the incorrect reading from tha sensor (O2 sensor also).

Other option is to wait for R3 to do the re-mapped (like the they use for S.Noe R3).
