92 GMC Yukon 5.7 4L60 - MegaSquirt Installation??

[TerryKing]

Hi,
I'm about to approach this upgrade on my Yukon. I want to have a more long-term reliable Engine Controller, and I have some intermittent surge/miss problems that I need to solve.

Has anyone installed a MegaSquirt2 or similar in this era 400 vehicle? I would love to get a copy of the tune you have set up as a starting point.

This is the unit I expect to get: http://www.diyautotune.com/catalog/megasquirtii-ems-system-smd-pcb357-assembled-ecu-p-171.html

Any suggestions, pointers appreciated!

I'm building a more or less similar setup. In my '89 c1500 I have a zz4 and 4l60e. I will use a painless transmissions controller and VEMS for the EFI, this will also control the e-fans.
