%META:TOPICINFO{author="LegoZ81" date="1110569760" format="1.0" version="1.1"}% %META:TOPICPARENT{name="IntroductionToECUChipping"}% You will need bridge J1 on the back of the ECU.

Add C49 & C50 and C91 & C92 on back

C49 & C50 --> .004UF

C91 & C92 --> .00001UF

Add the 74hc373 SMD chip.

Add a 29C256 eprom with bin written to it.

For RTP/Datalogging w/ Crome remove J4 on front.

Solder in a 4 pin header (snappable header pins 1x40 work GREAT for this and are VERY cheap)

All info is from the following threads:
