Thanks for replying for me. I've had one hell of a time making this site work. I click on stuff and get connection drops or just time-out weirdness. This is the only site that does this, on mulitple computers.

:yes:
I'm not seeing anybody complain about the bike throwing engine codes after removing the cats. Is this just not a problem or is there an ECM flash that comes with this mod?
Browser issue? Google Chrome doesn't play well with some forums on my computer; I had to downgrade to Microsoft IE :icon_biggrin:
NO error codes as you still use the two OEM o2 sensors. The ECM has no way of knowing if the cats are on or off as long as the o2 sensors are hooked up. If you wanted you can put a resistor in place of the o2 sensors to fool the ECM and will not get an error code, in fact that is what you have to do if you want to run a Power Commander fuel management system on a EFI system with o2 sensors.
The only thing that throws a fault code to the ECM as far as the exhaust goes is the o2 sensor's 12v heater circuit, not the data output line. You can have an o2 sensor go bad/poisoned and as long as the heater circuit is working(showing resistance to the ECM) there will be NO error code.
No ECM flash needed, nor as far as I have been able to tell you can't reflash the Honda ECM....ya I know there are several guys who claim you can, but after 12 yrs. building & selling an aftermarket fuel management system for EFI systems H-D and Hondas(B&B) I personally haven't seen it done with the OEM ECM. Now I have seen replacement ECU that are programmable, but the cost is way up there and would be used in a custom, high performance engine as far as I'm concerned.
The O2 sensors are before the cats, so it will not set any codes; you'd have to have an O2 before and after the cat for a comparison reading. The computer will continue to read the O2 voltage to determine stoichiometric fuel ratio so no reflash is needed.
srt8-in-largo, I have Windows Vista, and stay away from Google chrome.
:yes: to no codes and no issues with the cats gone. I'm no expert but it kinda sounds like Honda did what Chrysler does; lock the ECU. Even though Chrysler locks their ECU, it can now be fully programmed in the aftermarket... but it took well over a year for a company called Diablosport to break the software locks. I would venture a guess and say the same could be done for GL1800 ECU's but I question whether enough aftermarket support exists for a company to recoup the cost of doing this.
I run catless midpipes in my car and the stock OEM exhaust. With the cats removed, the sound went to a decidedly lower, bass-ier sound... nothing loud and obnoxious, just a deep aggressive sound at idle and, well, ok it screams like a banshee at full throttle :icon_biggrin: If the Torq Loops do something like this for the F6 I'd be a fan.
Any updates to this? I have the Rush pipes and wondered if this will get rid of the drone.
Does installing Torq Loops save much weight, I would assume it does. Also do after market exhaust such as Torq Master Pipes, or Rush Pipes, Etc. save weight from the stock exhaust.
