1988 Lotus Esprit Turbo X180 CIS

I'm starting a new project, which is is much more complex than just fitting Megajolt/E, code name X330.

My car:1988 Esptit Turbo X180, US Fed, w/ Bosch CIS K-Jetronic w/Lambda Engine: 2.2L 4cyl 16V, 8.0:1 CR, 10psig boost. C35 Citroen Trans and inboard brakes.

My Plan: I decided to get rid of the antiquated distributor and to hook up the Megajolt, EDIS ignition and S&J Safeguard dual channel "Vampire" anti-knock controller into one congruous system. Here is a schematic diagram tying everything together.

Also, I am replacing my previously installed AEM-1 boost controller with Innovate SCG-1 3-in-1 boost gauge/controller/AFR meter.

Very neat gadget, which, if combined with PL-1 Pocket Logger, (Innovate MTS Datalogger) should give a wider data logging capabilities.
I will add Innovate SSI-4 analog-to-digital adapter, which can log any 0-5V sensor output or other than Innovate, (PLX or other) stand along devices.
The SSI-4 device is a simple sensor interface that adds 4 inputs to an MTS Log Chain. The SSI-4 may also be used as a stand-alone device for logging data directly into a laptop with the included LogWorks software or it can be used in conjunction with any other MTS compliant device.

So, at the end, I hope I will be able to log the following:
1. rpm
2. IAT (PLX Devices processor w/analog 0-5v output hooked up to SSI-4)
3. MAP/Boost
4. AFR
5. CIS Control Pressure (stand alone 0-5V sensor hooked up to SSI-4)
6. Spark advance?

Do you know if it is possible to hook up the MegaJolt output to SSI-4 to log the spark advance values?

Here is the schematics

Question to everybody:
Do coil wires A and B need to be shielded, too ???

Fantastic!

The coil driver wires don't need to be shielded, but the sensor wires should.

Thanks Brent.

I got distracted by the nice Summer and sailing. Sporadically, I worked on few mechanical problems.

Now, I'm getting back to the Megajolt project.
