New ECU

I have long terms plans for keeping this car, so maintenance, cost and availability of parts is always a concern.  Thankfully, there's a solution - enter the FAST EFI kit.

This replaces all the sensors in the engine bay with newer, cheaper, and readily available (as in walk in to Autozone and buy a replacement that day) GM parts.  The rest of this post isn't going to be very interesting, as it's more for my reference later on if I need to buy anything.  The nice thing about this kit is it comes with all adapters you need to hook straight up to the L28 engine, which is a huge convenience.

First up, coolant sensor and thread adapter:

TPS sensor, adapter and wiring loom adapter:

MAP Sensor:

Idle valve and K&N filter:

And a couple of elbow joints with barbs for routing this to a vacuum point:

Air intake temperature sensor:

The MAF is deleted - there's a nice aluminium pipe for that:

A load of vacuum points will also be blocked off, as all the cold start stuff comes off as well:

Fully labelled loom (yes, all the sensor wiring is also replaced throughout the car):

Wiring for the touchscreen:

RPM Converter:

Spare wiring conduit to tidy everything up - I really appreciate small touches like this:

O2 sensor - if anyone knows the part number for this, I'd appreciate it!

The ECU and touchscreen display:

And finally, the first thing I can actually tackle... the O2 bung:

Next up will be removing the exhaust manifold to have the O2 sensor bung welded in.
