I couldn't find a lot of info about it, I only know about Unichip that works with it.

But my friend said, there's only one tuner for Unichip and he always play safe and don't want to push the limit of the ECU as he wants to keep his reputation.

Any idea about other ecu modification can be done? I heard that piggyback is useless. So which one will work best for this ecu?

Standalone? If yes which 1?

Really getting sick with my SVDO, have to rev frequently to remain the power.

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?

IMHO svdo can support piggyback since it only works in closed loop +- 3500rpm..

Can elaborate more brother?

The problem with the SVDO is that we cannot differentiate between fact and myth. Most of the claims are just 'my foreman says', 'i heard' kinda thing,

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...

means it works if rpm is below 3500??...

I have heard a Neo putting an SAFC at ZTH

a stand alone ecu is only as good as the tuner who tunes it.......
what mods have u done so far?

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. 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....

The problem now is that without modifying the ecu, the car will perform like no modification has been done after some time and have to rev hard frequently to bring back the power.

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...

if that's the case, go for a complete mmc ecu conversion........half the price of a haltech e6x, complete with a tuneable chip......

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...

I have the same thought.

From what i understand la the ecu whatever setting that is inputted into it, during the course of few days it will revert back to factory settings so that explains why the taxi driver have to go retuned everyweek, he say setting always lari when using NGV.

It's not designed to 'retune' itself back to the original setting. If that's the case, it's suiciding. It's designed to adapt to the new input parameters (if any), and making adjustment so that the control output falls within a predetermined range, for reliability and emission control.

If the ECU keep resetting back to base map, it's either teh car or the ECU has a problem.

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.......

can i tumpang thread?waja 4g18 2001 using what brand of ECU?.n what piggyback can be install with it??

4g18 using mmc

I tot 4g18 also using siemens? Although mitsu engine but ecu still svdo. Anyone can confirm?

Yes, 4G18 is running on MMC ECU.

so which piggyback brand is suitable for siemen vdo?
does a piggyback need an afc for controls?

Which Siemens VDO are we talking about?

EMS700 in the Campro, or the EMS400 in the 4G13/15/93?

satria neo siemen belongs to which model?

It's using a Campro S4P, so EMS700.

Dastek Unichip, Apex'i SAFC, Hydra EMS, even Greddy E-manage.. all work well on it.

Added on April 30, 2009, 11:14 amA piggyback only works when the ECU it in openloop.

This post has been edited by drexchan: Apr 30 2009, 11:14 AM

thanks for the info
might plan to add piggy back next year
RM2k can get or not...

whats the difference between EMS700 and EMS400??..

I almost got SAFC Neo last month, but canceled due to the high price because of the rising yen (from 1.2k increased till 1.6k)

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.

thanks... cant wait...

Elaboration below

Piggyback will be able to work in open loop

Yup..closed loop means intake air is metered,fuel is calculated to satisfy ratio,combustion then checked (O2 sensor) to determine the incomplete combustion then fed back to ecu to regulate the fuel ratio again.Closed loop works to produce best economy and tries to obtain a complete combustion.Problem is its hard to keep the feedback loop constantly updating at higher rpms so it reverts to open loop around +-3500 rpm..when in open loop,the O2 sensors feedback is not taken into consideration.In this range it is possible for piggyback to work since it wouldnt revert back to the O2 sensors feedback.

Just my 2cents

This is a closed loop operation:



Lets assume
X(s) is the MAP/MAF sensor
G(s) is the ECU
H(s) is the O2 sensor
Y(s) is the output (or amount of fuel injected into combustion chamber to satisfy AFR)

When in open loop, H(s) is not in effect,so theres no feebback loop (from this diagram,negative feedback) so you can tap the piggyback between X(s) and G(s) and set it to work only during open loop operation


*waiting for sleepwalker to do the corrections *

vr good info there sifo ryan....

still waiting for drexchan post on difference between ems400 and ems700...

Forgotten to mention, under light load (low TPS signal vs RPM), it's close loop. Once you step more on the pedal, it goes open loop, and that's when the piiggyback will work.

If the ECU can handle the optimum A/F for economical driving, let it do the job. Piggyback takes over only when you want better performance. This, to me, is just ideal.

As far as i know,the only way of reverting to factory setting is to disconnect the car battery...unless theres a limp mode im not aware of..

btw,you cant re-tune the factory ecu..

Can't retune stock ecu?
I went to Proton Service Center, they want to charge me RM86 for retune my ECU, since my idle rpm is too low...
Seems like expensive to me, so hold on for the retune for the moment

Mine is SVDO

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...

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??...

Drex,you sure the stock microP can be reflashed? Usually for mass manufacturing,the microP will be the type which can only be programmed once to save cost..like a dvd-r and dvd-rw..

somehow, someone did it with Proton engineers from the R&D.

what microprocessor svdo using anyway??..

I do not really know.

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?..

This post has been edited by ozs: May 11 2009, 08:16 PM

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??...

Added on May 12, 2009, 4:45 amsvdo has obdII socket for diagnostic device??..

This post has been edited by the_catacombs: May 12 2009, 04:45 AM

Ya i also wondering how to select, later i go to my car look for button, like wira 1.6 got economy and performance button.

u need the mut to select which map to use

Mut is wut? Obd2 scanner ar?

MUT or PDT2000 are ECU scanners and diagnostic tools use by Proton.

Sorry, just want to ask, is it this siemen EMS700 easy to fail? I mean kong? cause I wondering my car now have problem can not go over than 4K...some kind of rev limiter...

Auto transmission?

manual trans....2007 campro....

it will not go above 4k "no matter how"?

free gear
pedal to the metal
still stuck at 4k rpm?

yes...free gear, pedal to metal, still can not go....but if i play2 the pedal, its can go over 4 to 5~6K....but canot 7.5 as before..huhu...

no matter how still can not go...but its happen sometimes...sometimes OK means the car likes didnt have any problem...very weirds...
fuel filter,plug,cable plug,coil already change...air filter service..but the problem still there...intermittance.....

the funny is bring to workshop, NTF,no trouble found, the car oso can reach 7.5K...huh...

when we check with PDT, can we deteck if the ECU failer?

distributor.

clever!!!

Find me a distributor for EMS400 or EMS700..

unfortunately, mitsubishi.

u can use safc loh... svdo cannot mar...

y kenot?

er? EMS400/700 use COP?

For the Wira 1.3/1.5, GTI 1.8, old Campro and Campro CPS - ECU controlled coil pack, with ignition cable. The coil pack looks like a distributor anyway. For Campro IAFM, coil on plug.

This post has been edited by drexchan: Jul 3 2009, 09:23 AM

You mean for SAFC Neo it can be installed and function normally?

Sorry.. except SAFC Neo.

open loop can... close loop cannot... no meh??...

why cannot??...

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??..

yup can function above 3krpm without any problems..means can la

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....

what ecu and wiring harness are you using? mmc 1.3,1.5 designed to run in open loop only what

1.3 mmc ecu lor.... run open loop only??... my car got o2 sensor wor....

Finally, I've manage to installed SAFC in my CPS. Works perfectly.

ahh hassle free...

get the blue thingy ...

some thing name after E and a - after it

The Siemens ECU use the C16 INFENEON mpu , we at Tuned I-Chips too re-flash all Siemens ECU's at the most competitive rates visit www.tunedichip.com or call +6010 3640771.

Regards,

Zakie

Wow, at last Siemens ecu can be re-flashed? Are you based in Sri Lanka or locally as I see your website, you are in overseas. Please enlighten us more of what price are you charging (in Malaysian Ringgit please) for optimize the Siemens ecu to the competitive rates?

Im here in KL right now, we're having some specials for the season ending this 24th interested parties please call the above number. Our tune adjust the fuel, ignition maps and (CPS if applicable ) increase the rev and speed limiters. Approx, 5 to 6 hp and torque gains could achieved from a standard car. The power increase in the low to mid range will also give a slight improvement in fuel efficiency .

Regards,

Zakie

thanks..

are you saying that d non safc is workable in d vdo version of 4g13?

and d setting stays d same even if its long term?

do you have the ecu diagram?

conclusion is campro can be tune......

I saw before the SC technical head use a special PDT software to tune my car before.....it has a hidden button which i never see it in normal SC computer before.

his laptop can oepn throttle, ignition and many more features. However, this guy had left proton SC now. He help me to tuned before for RM60 to speed up the pickup. it did really improve a lot.

But I cannot get the software from him.....sad....

you drive BLM also right? how's the pickup?

tall guy. curly hair?is that him?



btw thats PDT tuning...
