Tuning For Long Tube Headers...

[n8dogg]

Hey guys,
I will be installing a set of Long Tubes on a 2000 LS1 Corvette. The 02 sensors will be located further down. I know this can cause a leaner condition (I think?).

What should I do to tune for proper closed loop operation?

Thanks!!

If you are remaining Closed-loop just log the LTFT's and adjust the MAF/VE accordingly.

You can also manipulate the O2 Switch-points. I have mine switching at 550mv, instead of the stock mv's. Others use 450 mv. Whether 550 or 450 works better with headers may be hard to prove. Try it out and log LTFT's and wideband readings if you have them.

Thats my 'O2'.
