ECU ROM Chip.

Well, I just recieved this ecu chip in the mail today. Later on I will be installing into this ectra ECU I have here. I will post up what I think of the install, and any noticable differences. Unfortunatly, a true dyno run between ECU's will have to wait until next month. But hey, there is always personal opinions right? :D

hey...the butt dyno works when it has to :)

i bought a performance chip for my original PR3 ecu off of ebay. i had my friend chip it. he took his time, and even used a grounding strap at all times. There is a whole bunch of connections (10+..cant remember) between the chip and the circuit board. When it is done by a professional or by Honda they have a machine that drops just a minuscule amount of solder at each connection point. anyways, we fucked up my ecu in the process (a couple of the connections got soldered together since they are so close to each other:()...and i had to by a proffesionally mugen chipped pr3 ecu off of my friend for $200. it was a costly error. My advice is to send it out and get it proffesionally chipped. It will save you your time & effort, a lot of annoyance, and money in the longrun. :)

Unless you're really good at soldering (like me!) :sun:

Or been to school for electronics. :D


Anyways, the chip is installed, and running great. I put in a quick release socket, just to make swapping back and forth easier next time.

As for any noticable differences? Well, it's hard to say. The rev limiter has been bumped way up, and it feels like 2nd and 3rd has a little extra punch to it. I just filled up on fuel as well, so we will see how gas mileage goes.

When i bought my chip off ebay it came with a quick release socket, i had mine soldered in by a friend of a friend that repairs cameras for a living...He solders TINY shit like that all the time.......i wouldnt of even touched anything that small
