Siemens VS MMC
|
|
Sifoos arnd need assistance,
What are the major difference/s if I do change my siemens ECu to a MMC ECU on my 4G15??
I have one MMC injector kit in hand-if the difference not going to be alot different then it would not be worthwhile changing?
PLease enlighten me as I am new to ECU and stuffs like these!
Thanks

Changing to MMC from Siemens need lot of things.
unless you get good wireman, you need ful wiring harness from MMC system.
THe you need the intake manifold with MAF sensor, distributor, etc.
Finally the cost and work might defeat the performance gained

agree with Joeker....
actually i do have a set of MMC injection kit with ECU ...but hte problem is i ask my mech...alot thing need change...the cost end up will be about 2k....and yet..power still the same..coz stock siemens change to stock MMC......why not use the money change the whole engine stil the same price...
But a gain MMC can play alot of thing and install alot of gauge as well...so in the end...is not worth to install it...unless ou change engine....to Dohc like 4g91,93..and otthers...

Sorry bro cant tell the recipe my big bro and friend will kill me they also in zth,they will read...My advice go do basic performance then you will get there...Sample 4-2-1 then must use center bullet..piping not to big just normal and small mufler suit 4g13/15,open port air filter sample hks then air ram must be custom follow the throttel body size..then the air flow sensor put near throttel body but not to near after that disconnect negative - battery after 15sec reconnect back...then start your engine at 10min but dont disturb anything or revving...
you also need to change cable plug,plug bosch super 4..if got money...some of recipe buy alfa romeo coil same as vdo
one more thing dont ever disturb valve tappet too... |
