Re: [DML] Emissions Tuning

[Marc Levy <malevy_nj@xxxxxxxxx>]

If you have the older Island turbo setup without the
CAT's, then you probably also have the Lambda
disabled.  On the early Island kits, they simply
remove the O2 sensor to richen the fuel.

Call Elenore @ Island Turbo and she can probably sell
you the parts you need to "update" the system to pass
emissions.  You will need to add 2 switches to the
intake that will allow the Lambda system to work
properly when not under boost.  As soon as the switch
sees boost, it disables the Lambda and goes full rich.

Also need to weld a nut to the exhaust pipe to install
the O2 sensor.  There were some other items removed
too, but I don't recall what they are.  Rob Grady did
the update to my Island turbo many years ago.  

You can also add CAT converters, if you so wish.
