Reanimotion,

I believe I'll be diving into FrankenCIS by using it to control the lambda frequency valve on my '87 930 in the quest for additional fuel in high RPMs / high boost. Then as I get more comfortable with the system I'll start utilizing it's other features.

So.... I need to put together a parts list for this simple system. Does the following list sound right?

- WBO2 controller with AFR outputs. I already have an Innovate MXT-L installed.
- MicroSquirt EMS V3.0 with wire harness.
- Pigtail/connector to connect Microsquirt harness to stock CIS lambda frequency valve.
- FrankenCIS firmware.

Thanks for everything you've done for CIS cars!
