ALS and Launch Control on Lancia Delta Integrale
Posted: March 1st, 2007, 10:21 am
Hello,
As Nikola Radenkovic (RPLab) has implemented ALS and Launch Control algorithms for RP control units, my car was one of the first two cars to test the new control strategies, do the data acquisition, based on which further algorithm improvement was to be done.
Both systems (ALS and LC) are already installed on my ECU through a reflash, LC is already finished and it is delivering full boost while the vehicle is stationary (before releasing the clutch).
Current ALS is set to mild version due to the restricted airflow of the stock ICV (idle control valve). We are doing the necessary modifications to my engine to prepare the hardware needed for a more aggressive ALS.
We are adding a secondary modified high flow ICV (idle control valve) donated from a Fiat Coupe Turbo powered only when ALS system is engaged (see pictures). This modification involved removing the intake manifold (very time consuming and painful task on a Delta 8v) and opening a hole in it to feed air from the secondary ICV.
We decided to remove the stock EGR system from the vehicle and in its place on the intake manifold we installed the ICV which was almost a direct fit as the mounting hole pattern on the Fiat Coupe ICV adapter was almost identical to the mounting hole pattern of the EGR valve with 1.5mm spacing difference, this difference was compensated with mounting bolts reground (from 6mm to 4.5mm) in the area protruding in ICV! We bored out the small EGR hole in the intake manifold through which the secondary ICV will feed air to the engine and fastened the ICV directly to the engine.
While the manifold was out of the engine we addressed some of its cosmetic issues, painted the manifold in red and brought a section of the manifold face to mirror finish by polishing it.
A question to Guy: While the intake manifold is still out of the engine is there anything worth modifying in it before installing it back? We wouldn't like to have to remove it again for something we can do now :o)
Thank you,
Ernest
