Caspro EKE Installation

Larry, you wrote:
I removed the Jacobs ignition system today in preparation of installing

Caspro EKE. The whole works will go on ebay along with some digitizing
tablets (who knows what those are?).

>From one good ole' boy from Missouri to another, I would recommend that
you use connectors when you connect your Caspro EKE, rather than hard
wire. One of the two failures I have had on our GMC was due to the EKE.
A few years back, as I was preparing to leave a GMCWS rally, I could not
the engine started. After using the ignition tester that Duane has
recommended, I found that I did not have any spark and it showed the
module was not working. I put in my spare module and still no spark.
Luckily, Duane had not left the rally so I went to him for help. We
installed his spare module and still no spark. He asked what was that
little box I had connected to the distributor and I said it was a Caspro
EKE. We disconnected it and the engine started. that is why I
recommend you use connectors so if you have a similar problem with no
spark you can disconnect the unit and go back to the OEM configuration
before you do any other testing. That is my 2 cents worth.

Tom - I'm not clear from your message if you have an EKE installed
but it appears that you don't.

The instructions that come with the EKE indicate to advance your base
timing from the standard factory spec of 8. I have mine set to 12.
I believe that we set Al Chernoff's to even more since we did his by
advancing the distributor while driving down the road.

The factory setting of 8 is a compromise that is actually below the
best advance under certain driving conditions but which will keep the
engine from pinging under the worst conditions. The higher setting
is not to compensate for anything else but to get better performance.

One of the advantages of the Caspro EKE is that you can have the
benefits of more advance but not get pinging because of it. The EKE
will automatically retard the timing (how much depends on how you
have set the controls). Mine is set to retard up to 9 degrees. When
I am running level and not under a heavy load the engine will have
additional advance but if it should ping then the EKE will reduce the
advance to a point where is doesn't ping. The result is a better
running engine which can use lower octane fuel and it will
automatically adjust for conditions such as a change in altitude,
fuel quality, hills, etc. that might require more or less advance.

Hi Larry,

I'm going to install my EKE also, But was hoping to find a cooler spot for
the control unit?? Yeah the connectors are needed just in case. I also put a
etch mark on the intake manifold/distributor where 8* would be, That way if
needed, switch connectors loosen distributor move to 8* mark and drive on
hopefully.
