Re: JRSC + ECU update part 2
Jay . . . we've recently been made aware of the 'cycling' which can (and often does) occur as a result of leaving the DSI switching valve on once the stock manifold has been removed. R & D has created a device to install in the switching valve which disables it and, in effect, turns it off. This stops the actuator valve from 'rattling' while it is still plugged in and prevents a '"check engine" light from illuminating. This will contend with the 'sewing machine' noises completely. I have no clue as to whether
the disengagement of that valve has any effect on the main computer of the car, but the parts being manufactured to correct this situation are going to be ready to ship to all of the customers who have installed the Focus SVT charger kits to date. As far as the ' re-flash ' that is something I know absolutely nothing about. It is generally said that the factory ECU should be left alone and not altered. The ' check engine ' light will remain on as long as the switching valve is plugged in and left in the
operating mode. If you simply unplug the valve, the 'check engine' light will still be on, but the noise will stop because the valve will cease to function...for the moment.
I will make sure you are on the list of charger owners who are supposed to receive the new part and, once it's in inventory, I'll be sure one ships out to you. I may need
to have you furnish ship-to info for this. The parts are due to arrive by the first week of November. Thanks for sharing this information with me. I think the CEL being
' on ' is only going to change after this new charger kit component is installed. I do not believe there's any harm being done by merely having the CEL on and the
manifold valve clicking away...... however annoying it might be. Once the new part is installed, this entire problem will go away for good. Thanks again, Jay. K T

Here is the latest [censored] from Ford on my SVT! I'll tell you more of the story if you are interested! This is what I posted on Focal- Jet.
OK, who wants to hear the BS? After the re-flash, and the local dealer "smoking" my PCM, they sent the bad PCM in for evaluation. Reason for the loss of all info? The supposed removal of the DSI manifold.
The reason I have a CEL and constantly cycling DSI motor? New PCM's produced after June, 2003 allow NO modifications to the vehicle. Therefore, with the DSI cable not attached, the motor will cycle until it senses resistance, and assumes the cable is connected, and the CEL lights. According to the Service Manager at Courtesy Ford in Portland, OR., I am stuck with the CEL, and cycling DSI motor due to the install of the JRSC!
Personally, I think it is a crock of s*%#! Anybody have any suggestions or advice? I absolutely HATE the singer sewing machine sounds that emit from the DSI motor!
BIG THANK YOU TO KEITH AND THE CREW AT JACKSON RACING!!!!!
