Renix E.F.I. tip

One difficulty Jeep owners have with the Renix Fuel Injection is setting the
TPS correctly.

I found myself needing to set my son's 88 XJ's TPS without a vehicle
battery.

The method I used was to take the throttle body off the engine and suppling
voltage from a couple "D" cells, then set the output voltage to 17 % of the
battery voltage checking the pins as described in my Chiltons or Haynes
manual with a DVOM. Then I re-installed the throttle body on the engine.This
was two weeks ago, btw.

We put a battery in the XJ yesterday and cranked her up.

Idle quickly settled in to a sweet 700 rpm initially and after the computer
finished it's initial learn cycle it dropped to 650 rpm.

I have found setting the percentage of the output voltage to be far more
accurate and easier than using the recommended voltage in the manual.

And being able to adjust it off engine makes it even better.
