Question for HUW Powell or anyone else

[Bill Green]

Thanks Tony. I am using the CIS-E temperature sensor in order to use the
existing wiring harness ( I didn't think to mention that ). I do plan on
using premium gas as you suggest. Its not my daily driver so the extra
expense should be tolerable.

CIS-E is set at 8-10 mA.  CIS-E-III is biased at 0 mA (supposedly because if
the ECU goes dead, the engine is set at normal idle).  If you're using the
CIS-E coolant temp sensor, then the ECU is expecting and scales according to
the temp sensor.  Since you don't have the knock sensor better stick with
premium gas since your ignition can't retard.

Hi again! 



You may remember me as I am the lad who thought a loose starting motor was
really a serious knock in his new NG engine he just installed in Audi 4000s
quattro. The engine is installed now and seems to run strong. The only
problem is a brief stumbling when going to back to idle from higher rpm
before calming down and idling fine at about 750 rpm. 



My question is whether I should set the initial  mixture setting on the air
handler (using a rig exactly like the one you made to measure the milliamps
between the ecu and the differential pressure regulator) so it fluctuates
around 10 milliamps or 0 milliamps. I am using the original NG injectors and
a fuel distributor / DPR from an Audi 90 which had a NG engine in it. The
ecu and the air handler however are both from the original JT engine with
CIS-E  not CIS-III. I currently have the base mixture set to hunt around 10
milliamps. 



By the way the distributor is also from my old JT engine which utilizes a
vacuum advance setup since I don't have (and don't really want) the knock
sensor / electronically controlled timing thing. 



Should I set it to 0 or 10 milliamps? 



Thanks in advance.
