I've done a search and haven't been satisfied with the results.
I'd like to know definatively the following:
1. Check engine light: from what I've found, the light does NOT affect engine performance. True?
2. Electronic devices to turn off CEL: which ones actually work?
3. Has anyone actually measured any power gains from replacing the Cat w/ the test pipe?

 

i have the 3 wire caspers unit and it works fine.. it does turn off the CEL.. and im pretty sure the light doesnt effect performance..

 

the honda cat seems to be quite free flowing for a oem cat, nevertheless there should be some gains up top, most only a couple horses to be gained unless your forced induction or have some serious breathing mods done.

 

Has anyone actually measured gains on a dyno yet??

 

The 3 wire Casper's simulator did NOT work for my '02. I have a Lake Effect Performance simulator that I am going to try (eventually). The CEL does not effefct performance.

 

Matt,

Try the ECG simulator.
I would like to run the testpipe at the next dyno day. Will I lose bottom end torque with the testpipe? I don't need the extra top-end for street driving. Anyone with comments on the difference?

 

Asura,
Where can I get the ECG simulator?

 

Diablo has them. Ask for Mike- 925-371-7222.

 

anyone?

 

Couldn't get a hold of them?

Gernby's Lake Effect simulator is made by ECG.
