CIS-E notes:

1. There are no piggy back computers for CIS-E
2. Rising Regulators don't work on CIS-E
3. On the CIS-E cars the blow off valve does't need to be rerouted back to the intake since it is before the metering unit.

On CIS-E cars to get fuel enrichment you either have to:
1. Send false signals to the Fuel Pressure Control unit under boost.
2. Add external injectors L-Jetronic type and control them by HKS Additional Injector Controller or equivalent.
3. Convert the car to an aftermarket Fuel Injection system.
4. Add a booster pump ala Porsche 930 style which will require fiddling wth the Fuel Regulator.

GOOD LUCK!
