Hi speed2horizon,
Thanks for the info bro. So u mean by rechip is more better than using EMB?
I tot EMB got more function to play with rather than rechip the stock ECU (MMC).
Or can you tell me what kind of better things u mean by rechip than use EMB.
If it's that good then i'll preferred to rechip mine, save cost. hehehe
Btw, i also tot rechip is plug & play, take out the stock chip and socket then replace with tuned chip(of course done by pros not newbie like me). What kind of tuning need to be done after rechip the ECU bro since the chip is already tuned.
Sorry in advance for my noob question here bro.
Nope.. rechip will never work the best with a tuned chip.... Ok... This is how it should be done. Look for an ECU with Eprom(make sure there's Eprom) microprocessor. Get it removed, and replace with 28pin socket.
The way to identify is as follow.
From the sticker, u should be able to identify.
The EPROM CHIP
After replacing the chip with the socket, it will require an eprom emulator to temporary replace the microprocessor. With the right interface like Tuner Pro RT, u can change all the definition according to the engine set up, the parameters involved, injector size and etc. Then it can be tuned to to suit your new set up.
When the tuning is completed and the parameters is confirmed, the program is extracted from the emulator and burn into a new Eprom chip. Then the chip will be inserted into your ECU.
The tuning method is all like standalone, though the parameters may not be similar. Exact injection timing, injection in ms formulated to targetted AFR, and not just correction like piggyback.
In other words, it's as good as standalone if it's done on the right hand.
If there's changes on your set up, all u need to do is to find back the person. remove the chip and destroy the program with UV ray. And burn the new program in the same chip.
