Regular Senior Member 1,011 posts Joined: Mar 2010	even im on vacation, but i feel obligated to answers some of the questions even i'm not related to proton :-). About 3k rpm rules b4 1k km, during downhill, if downhill engine braking is applied auto by tcu, it means engine is driven by the cvt@gbox, not ur throttle, it is ok, but still can cut off the engine braking by put in pedal pressure@throttle,it will go without engine braking. About the engine harsh sound, dunno, which one, but if i not mistaken, they replace it with pet 15w 50 which is thicker, thus engine need to work hard n produce more sound. I already suggested few pages ago about engine oil n did recommend 5w 30 previously if u read back. N shell that r u using is semy syn, n the fully syn is 5w 40, but u can get petronas fully syn 5w 30@5w 40 rating. Even 0w 30 if u have the money. But i dont think 0w 30 is much needed. 5w is suffice enough for daily ride. In order to top up the coolant, most recommended is top up with coolant. Just by a bottle, just enough to top up untill futher reflushing needed. But u can still mix it with deionised water@distill water aka battery water. Not ro water@mineral@filter@tap water. If me, i will emptied the resevoir that fill with mix water, n replace it with original coolants which actually already premix with correct mixture. N one more thing, u can bring ur own 5w oil next time, n never ever mentioned that u change the oil b4 hand outside. But really worried if the oil filter isnt the original one which diff in packaging which can be seen by the foreman. Hopefully its the oe one, so, they wont notice from outside. Inside,is diff story then. About preve cfe hu, if not mistaken, nissan also used it for sylphy(the same bosch unit),which if i not mistaken,sylphy is almera big brother. May be im wrong then. Added on November 11, 2012, 10:33 amon another note, on side mirror, there were numerous complaint abour gen2 dife mirror design which design with fin to facilitate aero dynamic but scarificing a bit by making the blind spot bigger. So, now they change it to a bigger one, which is better for its main function, view, rather than aerodynamic form. On engine note, yup, engine note is louder, plus the engine sound drone coz cvt, u r rev continuously at the same rpm, n cvt whining. The manual will be diff. If u have opportunity, test drive saga flx manual n cvt version, u will notice the diff in engine note, n being manual, no cvt whining :-). Even in flx, which is less sound deadening, the manual is quieter. May be u can refer to caradvice.au, they just recently test drove both cvt n manual flx. Added on November 11, 2012, 10:38 amn by the way, many forgetting body control module which is normally offered by higher end model which available across preve n exora. Just notice perodua discard auto lock function due to safety reason coz they dont have auto unlock function during collision which actually included in bcm. For high level japs n even korean, they offering some of these functions, which is more than twice price than preve@exora, but to get almost all same functions as in preve n exora, u need to fork out more to high end model. Sadly, many dont notice that. This post has been edited by mat79: Nov 11 2012, 10:38 AM

There is hardly any engine grinding sound anymore, the power output so smooth and responsive. A True Preve CFE I must say.

The new TCU/ECU mapping is good, but i scare of engine mati. I always change gear between D and R quite fast every time. I always havent brake fully then st8 change to R.

Still sustainable Need to do more to increase the service intake soemhow. Many more dealers will come in soon Petronas 5w30 API SM semi is good, just that most Proton Edar dealers dun have them in stock since it isn't a common grade used in all vehicles. For Suzuki, all of their cars using 5w30 Petronas API SM grade though This post has been edited by allenultra: Nov 11 2012, 12:58 PM

Sadly, many dont notice that. Hi mat79, thanks for helping out even on vacation! Regarding engine oil grade, I think we do not have much choice, SC use this (15W/50) we have to accept. Some SC not allowed to bring in own engine oil, even worse, if want to make warranty claim one day, afraid the engine oil will be blamed. For the coolant, what should we tell the shop (usually auto spare parts shop?) which particular type of coolant we need? If we walk in the tell them radiator coolant, I think a normal common coolant we be given? How to tell which premixed coolant is suitable for CFE? Any special label on it? Thanks, enjoy your holiday!

And lastly the problem that I worried, the engine rev high then low, seems like to to die off at low rpm... Thats happening to manual variant as well. Apply throttle, engine rpm goes up after about a second, release half clutch, engine rpm drop drastically to around 500 rpm and jerk like wanna stall, then rpm automatically shoots up again after about a second or two eventhough throttle remain constant, release full clutch to let car goes. If straight away release full clutch after applying throttle then have happy time trying to restart yer engine again. QUOTE(GoldenHawk @ Nov 8 2012, 12:24 PM) P/S: Are you a Prevoc member?

QUOTE(mat79 @ Nov 8 2012, 04:47 PM) » Click to show Spoiler - click again to hide... « hi, sorry for late reply, super duper bz lately, maybe need a long vacation afterwards. On dbw lags, actually hard to adjust it, not bcoz incapable, but due to emmision cntrl, which prtn only use same setting across the region. Since it is manual, compare to cvt which still can alter its tcu(which is done by punch with prtn collaboration), its fix. Can adjust the clutch manually for make it easier to launch by make it shorter, but if wrongly drive it, may damage the clutch. The only things left is ecu mapping. I dun know too much details on iafm+ ecu mapping coz its diff people responsible for the mapping part, for iafm+, n another for cfe. Maybe u can ask sc everytime servicing, whether there is an update, but mostly only branch eon@prtn sc has the facility@service. Since preve is quite heavy, agressive mapping may cause pretty high fc. Mostly setting is to provide balance between reliability, fc n performance. While waiting for any setting, just adjusted u style of driving when power is ur concern such overtaking n need to move fast out of junction. While dbw throttle is diff than cable throttle, u can see how fast the rev drop after releasing the clutch during 1st gear, rev higher, so that when it drop, just drop at the region atleast at 2k rpm where by around 80% of torque already generated, such reving to 2.5k rpm(only apply if u need to drive faster than usual daily driving.) while overtaking, make sure everytime u drop ur gear to overtake, the rev is around 3.5k rpm to 4k rpm, to get the most torque, and stay in gear until reaching 5k rpm atleast b4 upshift coz to take advantage of the runner shift to short one to promote faster air n better combustion. But that is only for engaging driving, for normal, rev to max 4k rpm b4 upshift is just enough for overtaking, n shift to the highest gear as soon as possible after finish overtaking coz reving more, more horse power but also means more burns of fuel. If u notice,in any manual car, the gear ratio choosen related to peak hp n peak torque available. Generally, like in iafm+ manual, peak hp is at 5750 rpm, peak torque at 4k rpm, so, everytime u rev at peak hp at 5750 rpm and upshift,the engine rpm will drop around 4k rpm on the next change, n u continue rev to max hp,upshift, the rpm will drop around the region of max torque until overdrive gear. Thats why high rev engine also have high torque at high rpm to balance it out, in na form of course. It jsut general rules coz very engine has diff character, but the trans tuning is to balance out hp n torque coz if not, can cause severe drop in pulling power, can cause high fc but no use coz power is un accessible through out the rev range. Mitsu 4g18, eventhough has a lower rpm for max torque, ideal for town driving, but if accessing the whole power like revving to max hp, its not reallyengaging coz torque is dropping too early, so it become slower n slower reaching top hp. Good chunk of information you've given there, greatly appreciate it. On the other hand, though, low sales figure on manual iafm+ makes proton seems like lazy to improve the ECU for stick shifter while those CFE variant keep on getting hot updates regularly. Sad case scenario. I was thinking maybe proton could at least improve the stand still acceleration for iafm+ such as making the first gear to engage the responsive S Mode like those of in CFE but retain the same current setting for other gears. At least safer when coming to a stand still while negotiating a slope or rushing out of junction, without reving the engine too much. The throttle lag is dangerous in such situation: Imagine the car slow down when reaching roundabout. At a glance, there is still quite some distance with those cars traveling at the roundabout. So it is safe if rush into the roundabout quickly but not so if entering it slowly. So quickly shift to first gear and pedal it but the slow response makes it enter the roundroad at a turtling pace a.k.a moving as if without any throttle being pedaled. The throttle only starts to response after some time so in such situation where agile response is much need then it'll be unsafe. If the approaching driver at the roundabout was either insane or slow to respond then you know the akibat lah. Coupled with the fact that it might even stalled easily halfway during first gear made it even scarier! The same goes to maintaining the position without going backwards while climbing the hill at first gear which I find harder to do compare to the old proton hero. Such skill is needed during a frequent stop-go situation at sloppy road. Well, not to say it's a bad car, but like what GoldenHawk said, there's still rooms for improvement! Hopefully the full potential can be unleashed for all variant, not just for the majority CFE. Come on, we're 1Malaysia afterall. Don't ignore the minority(manual iafm+)! I believe they can improve the driveability of the car without sacrificing the fc much, or even making it better after retune! Agree?

Yup, some dealers are afraid when using diff oil, but its mention clearly in the warranty agreement that its not specified any brand, just recommend to use petronas brand, n it mention to use the same rating@better than recommended. About coolant, its actuallt weston based coolant, hard to find outside, but still available. For hassle free, just buy from any prtn sc@parts. And about rpm high n low, i think what he mention earlier isnt the rpm high n low issue when lifting the clutch, its when u cold start, suddenly move to d mode@r mode, suddenly rpm went crazy a bit, up n down many times. Actually, its not that cfe is being given much update, previously cvt did being update even for flx. For cfe, when they change the strategies for cvt, so,need compliment with ecu mapping to make it perfect. Since cfe has enourmous amount of torque at low rev which previously being cut@torque reduction apply, so, by changing the strategies, it allow more torque to be applied. While in iafm+ form, not much torque reduction being applied since the torque isnt that high at low rev. To be honest, on engine alone,cfe already generate more than 150nm torque at 1.5k rpm, which iafm+ need to reach 4k rpm to get the same amount of torque. The only thing they can do is to sharpen a bit on dbw(which involve ecu) during the launch. What happen is, preve weight is heavier than flx. In 1.6 form manual flx, it doesnt poise the same reaction as preve, even with the same tuning, its responsive. So,its really a tough job for them to tune it, especially when try to meet emmision n fc n power in balance form. If u notice, they also try changing how the tcu react n even change diff contstant ratio on iafm+ cvt to facilitate fc. For manual, its really hard coz no tcu involve, just playing with the ratio. Im not so sure whether currently they r doing anything to give it a bit boost., hopefully they do.
