ROAD TEST
Test performing conditions:
- warm engine ( water temperature > 80°C);
- engine RPM not exceeding 4000 rot/min.
For this test, it is recommended starting from a sufficient low engine RPM, in gearbox third or
fourth gear, accelerating then progressively in order to obtain a pressure stability in the inlet (PR001
= inlet manifold pressure) for 10 seconds in each area, as per next table:
Enriching adaptive correction
Area 1 Area 2 Area 3 Area 4 Area 5
(mbar) (mbar) (mbar) (mbar) (mbar)
250-------------- 399 ---------------- 517 ----------------- 635 ----------------- 735 -------------- 873
Average 325 Average 458 Average 576 Average 694 Average 813
After performing this test, the corrections will become effective.
PR031 parameter (adaptive enriching at idling) is more fluctuating in the idling and small charges
phases, and PR030 parameter (adaptive enriching during running) is more fluctuating in the mo-
ment of medium and full charges, but both parameters are active in all areas of inlet manifold
pressure evolution.
It is necessary that road test to be followed by a normal driving running, constant and fluctuate,
on a 5-10 Km.
After test performing, connect the CLIP tester and refer to the values of PR030 and PR031
parameters. If their values are initially at 128, after correct performing the road test, they must
change. Contrary, perform again the road test, strictly observing the imposed conditions.
