Thread: Beginners Guide to Chipped ECU Tuning

You can always use vmware to run windows on a Mac or Mac on windows box

Yup I was gonna suggest that next. Though the cost of Fusion or Parallels plus cost off XP/Win 7, might as well buy a cheap XP laptop and keep it in the car as a tuning laptop.

Thanks for the response. I will probably end up running windows through boot camp so I don't have to borrow my bros laptop.

I have a RTV2 for my B13. It currently has a V1 program on it and I am trying to load the V2 HEX file on it but it will not load. I believe that I need to "reset" the ecu per:

"If you've uploaded a firmware that bricks your RT board…

If you've managed yo brick your board (i.e. written some code that never responds to serial commands) you've got two options- either manually reset the board while the Colt loader is trying to connect, or use a hardware programming tool like the ICD2.

To manually reset the board first remove the cover. Next, find JX as show below."


Can anyone tell me how I got about "resetting" my ecu so I can load the HEX file into it?
Thanks.

That's a new one for me, hit up Dave, dfddf2, he might have more insight.

Thanks for the reply. I had emailed Dave. I have a local guy who has an ICD2 at work that was able to erase the ecu and load the hex file. Looks like I'm in business.

Good deal!

Awesome, you should consider getting tunercode for it (if obd1). You wont regret the new tuning features.

I was not able to get the ICD2 to do anything, but on the programming port there is a CLR pin for the memory chip. I was able to start the bootloader then ground the CLR pin and it loaded in the HEX file. For anyone who needs this, it is the 6 pin connector that is parallel with the PCB on the underside. The pins are labeled on the top side, 1 - 6, pin 1 is the CLR and pin 3 is ground. Using a piece of wire connect the 2 pins and the bootloader will initiate the programming.

I have tunercode that he could use, not too familiar with this stuff yet but i hope to learn as i go.

Sorry for the n00bness, but I'm looking for engine management/tuning for GTi-R engine into a 2002 G20 5mt. Do I have any options for hardware/software? Don't worry, someone WAY smarter than me is very capable of installing and tuning it.
