Hi,

I previously owned a calibra to which I fitted the C20 LET phase II software. I have some questions concerning the Phase II kit for the Z20 LET and would be grateful if Arno (or similarly knowledgable person) could answer.

1. What boost levels does Phase II run (overboost and boost held)?

2. Fuel pressure is not uprated. Is the standard fuel pressure really enough? C20 LET phase II requires an additional 0.5 bar of pressure. How come the Z20 LET does not? I assume the Z20 LET runs 3.0bar FPR...

3. Z20 LET phase II alters the traction control to allow for a more agressive take off. Can you give me more information on this?

4. There is no actuator spring as part of phase II. Is the standard actuator strong enough to cope with the increase in boost (obviously after an adjustment)?

Danke!

Hi Dave !

The trottle response is now perfect at the EDS-Z20LET Phases , the original fuel pressure is 3.3 bar , more than enough for the big injectors !

The traction control reduce normally when spinning wheels are detected , the driving force of the engine down to 80Nm , thats nothing !

The power is reduced for min 3 sec time , it feels like endless !

A hard driven OE car reduces engine power in every circle , that makes you mad !

Now our traction control programming reduces only 10-20 % the actual engine tourque and then only very short time ( max 500msek ) , so that with slightly spinning wheels you can easy accelerate full load , without power cut !

The original waste gate actuator is twice strong then the C20LET version!

At a wet road the wheels are spinning at 4 th gear !

You can get a test launch at www.regal-autosport.co.uk they have one of the first phase-3 Coupe prototypes !

regards ASH

Ah, thank you Ash! I am learning more and more the subtle differences between the C20 LET and the Z20 LET.

Can you also tell me the boost levels Z20 LET phase II is running?

:D
