Hi Hata,

Siemens/mmc is the ecu not engine.

My suggestion is better u convert to mmc version before you start any modification. Else there will be limitation here and there all the time. Plus it wouldn't be as powerful as mmc version no matter what modification you made to it.

Hi Hata,
2nd gen of Satri GTI?

:hmmmm:If yes...,
I don'tknow how it could be indicate by MMC & Siemens...:hmmmm:
As i know just maybe short form Step 1 & 2...

But if urs is step 2, means there is NO idle timing is allow to adjust by manual(philips/srcew driver) on throttle body
& u do every time u need to tune/adjust by something like a small console of pc... at bottom of driver dashboard...
If it's correct means u got nothing can modify same as wira a/b 4g15 S/Edition.

According to the foreman, there are about 7 addition sensor compared with step 1 & it's purposely to limit the modification...
It can't feel significant deifference after install the AFC NEO...

***Sifu-sifu, correct me if i'm wrong***

or else, when u upgrade turbo kit, use standalone ecu...

 

[hata]

Tanx dude..is it when i change my ECU, throttle body and wiring mean my engine was converted to MMC??? wut about da sensor there?? Is any one there have this set (ECU, throttle body, wiring and intake manifold) and what the ideal set (ECU, throttle body, wiring and intake manifold) for my car?? can use "ROJAK" one huh???

using MUTII to do the tuning....siemen ecu......it limits yr speed to bout 160 to 170km/h
so u will feel bit lagg.....bolt on to after market ecu or the stock 1st batch mmc ecu should work wonders in yr 1.8engine.

 

[JackWaiKit]

Guys,...
Wait wait wait...

If I'm not mistaken, u can't do any modification bcoz there another very signification factor to limit the power...which is the 'crank shaft sensor'...

If u change the top & wiring, i don't think it's work...
instead of wiring, I don't know whether it could be suit or not...
If u change the block together, better convert to Mits' 4G93 engine lantai...I suggest...

Hi Evo.Z
Is there any big different perform the 'MUTII'?

Well my fren was in experince that not really such big diff. after modify the air filter, 2inch piping, adj cam pulley, SAFC & etc...(fuel pressure regulator...maybe; forgot...long time oredi liao)
It's seems like fuel limited for displacement...

And the only way to modify is air filter, piping, adj cam pulley, & a famous brand of crank pulley(forgotten...AEM maybe) with crank sensor (same function also)...but very high cost... to lighten ur REV...

Correct me if I'm wrong...!!!:wavey:

 

[slipar]

so bro hata..
i heard that ur car has done 2" piping & big muffler..
any diffrent in performance..

campro engine using crank sensor..
does the siemen engine use crank sensor also..
do enlighten us all of sifu here..

 

[popout]

my Gti also limit at 170km/h so if i install RSM can solve this limit problem??

 

[JackWaiKit]

well guys,
As i earlier mentioned,
I think u can't do anything since the crank sensor has limit the power on top speed...

Anyway, u can try but i don't i would be much difference no matter AFC Neo or RSM...I guess!

 

[gtiwtks]

Guys,

RSM is a rev/speed meter. Wun do any help to increase your top speed.

AFC Neo is useless againts siemens sgti due to close loop. It will auto adjust to revert back to initial setting. Can only use smt or unichip or dynojet commander.

MUT2 is the proton engine diagnose tool. It can scan and delete fault code if there is any plus t/b adjustment. No tuning can be made.

Siemens sgti does have crank shaft sensor. But i think most the car have it. It just that siemens gti have crank keyplate mounted on the crank pulley. So far only mythelogy brand of lightweight crank pulley can be used for siemens sgti.

 

[JackWaiKit]

So is there any big differentce after install the lightweight crank pulley with sensor version?

Well I might doubt...
Maybe ligther REV but not increasing the HP...!!! I guess!

so can change the ecu just like that ka bro..
i think mmc & siemens got big diffrent in the wiring & intake system..
air flow sensor also not same..

me confused already..
