most standalone ecu will work... because it totally replaces the oem ecu..

piggyback which interupts/changes the oem data from the ecu would not work because siemens ecu is self-learning type... means it constantly changing its data and fuel mapping... hence, whatever piggyback u install will not work...

unichip however works as it replaces the chip inside ur oem ecu... in other words, its a generic plug in performance chip....

another method available is ecu reflash... i've seen N1 reflash adverts for campro engines... since campro uses svdo ecu, should be applicable for all svdo based engines...

Oh, so do you know normally SVDO do what modification?

I mean, something that is worth for the performance given.

Like what my friend said, Unichip tuner don't push the ecu to the limit and so the bhp that can be squeezed is very limited also, don't know it's true or not.

Any other standalone ecu to recommend?
*
yes modding svdo is worth the performance given... in fact svdo is a self-learning ecu, newer generation than the much preferred mmc... but many local workshop dont know how to tune svdo ecu based on old skool style... datz why it is deemed useless and hard to tune....

in fact more n more modern cars use such kinda ecu... what makes svdo abit of failure is the programming part... modern age tuning is more towards software tuning...

QUOTE(ryan_hustler @ Apr 26 2009, 10:48 PM)
IMHO svdo can support piggyback since it only works in closed loop +- 3500rpm..
*
means it works if rpm is below 3500??... unsure.gif

Not much of modification,

-HKS drop in air filter
-10.0mm spark plug cable
-iridium spark plug
-mivec extractor
-pivot blue raizin

Actually I have reach the torque that I am looking for, but the problem now is that I need to rev the car hard frequently to maintain the performance or it will become torqueless and less responsive.  wink.gif  wink.gif Sigh..
*
such mods does not require a standalone ecu... if there are other possibility, dont waste so much money investing a standalone ecu... unless u going to have bigger upgrade soon....

Yeah karipap ecu will relearn in a few days, one taxi driver told me his waja campro running on NGV needs to retune everyweek, dono he blow water or wut la but considering the fact that running NGV requires a more advance timing maybe there is some truth to it.
*
yes NGV requires more advance timing coz they have higher octane rating... yes u can maintain normal timing, but u will have sluggish performance...

can buy a standalone ecu to solve the problem mah?

I think standalone is more flexible.

Sorry i new in car.
*
yes... but minimum price for a standalone cost anything above rm4k.... tuning a standalone ecu is not easy either... tuner has to tune the ecu with a fresh mapping, unlike piggyback, they jz adjust the current mapping... hence, tuning a standalone ecu is also much much more expensive...

means piggyback ecu only works with svdo if ecu is in open-loop??..

that's just the price of the ecu unit....... have done some svdo gtis to use haltech and the total cost, inclusive of several parts that need to change to suit the ecu came up to close to rm9k.......
*
yeah... i heard my mech said rm4k is jz the main body of the unit... exclude all necessary harness, software, cables, etc....

Which Siemens VDO are we talking about?

EMS700 in the Campro, or the EMS400 in the 4G13/15/93?
*
whats the difference between EMS700 and EMS400??..

There's another option for Siemens, Works EMS-1. about RM1.6k also. Compete with harnes and software if not mistaken. I may try this.

Difference between EMS400 and EMS700.. a lot. will elaborate more next time i post.

Both SVDO EMS400 and EMS700 can be remapped and retuned. But only Proton knows how to do that.

Increasing the idling speed is not tuning and it's not worth any cent to so. Just clean the TB and let the car idle for 10 minutes, then drive like normal for two days. If the problem persists, the TB has a problem, and "tuning" will not help.

recently i saw N1 reflash offer ecu reflash for campro engine... hmm.gif

The core program are still intact even with reflashing. You only change the mapping by reflashing but reprogramming can do even more.

so means only proton knows how to reprogram the microprocessor??...

the ems700 ecu has some maps stored in the ecu......  gives u the choice to select what maps u wanna use..... but u cannot re-programe the maps, just select like multiple choice.......
*
how to select??.. any button or knob on board to select it??.. or need to hook up onto a device/laptop to select the mapping??...

is there any software that can monitor the ecu?..
Wira A/B 1.3 injection..

the rs232 > laptop > software..

i just need to do diagnostic only.. view error..
possible?..

after googling around i've found some..
http://www.freshwap.net/forums/application...ega-thread.html

anybody use any of those software before?..
*
svdo has obdII socket for diagnostic device??..

Siemens VDo is not 100% close loop mah...

SAFC Neo can't work because the type of sensor it's supporting doesn't match with siemens VDO.

oh icic...

eh, mmc got open loop and close loop or not ah??..

depends if got 02 sensor..i think the mmc 1.6 above is closed loop,1.3 and 1.5 is open loop..means no feedback sensor
*
means if got o2 sensor means for open and close loop??.... without o2 sensor means only open loop??...

i remember the earlier wira 1.6 batch has no o2 sensor...

02 sensor is what makes a system closed loop as there is feedback and correction..refer to my block diagram. The open loop part comes at a higher rpm as its not possible to correct the afr.(maybe some hi-tech stand alone can do so,im not too sure)
i think 1.6 got,but this im not too sure as well..but with 02 sensor is definitely closed loop
*
now i understand why my 1.3 ecu cannot support even though i upgrade injectors and throttle body accordingly... its the switchover point of close loop and open loop not suitable for my engine already...

i guess each time i tap on the throttle pedal, it immediately goes to open loop...

no wonder my fuel consumption for town drive so bad... whenever it goes into open loop, it ignores the signal from o2 sensor....
