I have seen references to this "Digifant tool" from time to time. Did
Darrell make a DigiJET counterpart? If so, where can one be had?

Hi All,

I am greatly indebted to Darrell for conceiving of Digitool. I too have
become afflicted with "Digifant Syndrome" and have been both relieved to
know others are experiencing the same symptoms i.e. unexpected engine
hesitation but then frustrated that the diagnosis of our collective
problems is so elusive.

Having recently installed the Digitool on my '87 Westy and hoping this
would net a solution to the intermittent hesitation and running rich
problems I was having, everything pretty much checked out per Digitool
although I am not certain about the acceptable test voltage ranges.

I have tabulated these test results as follows:

All LED's indicate proper functioning of start, fuel pump, fuel injectors,
throttle switch, and coil although it  pulses dimly and occasionally goes
out altogether. Ambient Temp = 40 F.

                        cold                  warm                WOT
                        idle                   idle

                        --------                --------
--------

Temp 2             1.46v                 0.18v                0.18v

AFM                 1.74v                 1.28v                2.35v

Temp 1             1.67v                 1.29v                1.29v

OXS                 0.43v                 0.82v*               0.82v

*When hesitation occurrs oxs fluctuates rapidly (< 1 sec.) between 0 - 0.8v
under load except at WOT (defaults to 0.82v) and sometimes hangs around 0v
for 3-4 seconds during acceleration. When running ok
fluctuations are less rapid (~1 sec.) and the range is reduced to between
0.2 - 0.8v. ECU pins 13 & 19 were checked for proper ground. OXS warm reads
0.54v when disconnected.

Nothing seems extraordinary other than 0.82v OXS reading seems a little
high and AFM reading at WOT a little low. Any and all suggestions welcome.
Thanks!
