Tuning the LT5 - Series

[XfireZ51]

All,

Here is a brief primer I put together that was presented several years ago at the 2014 Gathering. Its an overview on tuning. Not meant to be comprehensive.

Great. Thanks to you, Marc, Jerry, Pete, and everyone else for passing along knowledge, tips, tools, and parts. Keeping the Beast alive!

For those wanting to use the ALDLdroid App, you connect to the tablet after selecting the appropriate datastream for your year ZR. These correspond to the
correct ECM "mask ID" for your ZR. Once you have selected the proper .adx, go back to Menu and select Connect to ECU.
Just to refresh. Either one of two masks will work for your car as the datastreams were not changed w the change in the ECM code.

90 $8E or $8EA
91 $AF or $AFA
92 $D0 or $D0A
93-95 $F0 or $F0A

Follow the sequence in the posted pics. I am using the $F0 datastream for illustration only. Yours may be different. Choose the one appropriate for your year ZR.
