Contour Enthusiasts Group Archives Forums Modifications Duratec Performance MSD DIS 4 is in, but throwing codes.

108178 is the lot number. Anything before that is a door stopper for a Ford.

Yes

Did you have any issues getting everything to work correctly?

Besides the adapters that wouldn't work no. Once you have the right ones it starts right up.

Wasn't Buckshot using the same system when his 3 liter bit the dust.

I was the one that started this post. Install was easy enough. I also had the CORRECT "new style" tach adapters with a fresh lot number straight from summit. Codes everywhere man...

The car will start right up and run like a champ after you reset the computer and will run fine until you turn the car off and then restart it...then you get the error codes for primary/secondary circuit malfunction for coils A, B, and C. I think that the cause of the malfunction is one of two possibilites: computer senses either too much voltage when it grounds each coil pack or the computer senses the multiple spark circuitry and thinks its an error. You will notice that one of the tach adapters can get very hot.

I started by calling summit to see if there was any alternate part numbers...there were not. I then started working with MSD, who seemed confident that they could revise the tach adapters to correct the problem. Nice company to deal with, but that wasn't the problem....

I was going to use the MSD DIS-4 to control timing and add spark consistancy and power as part of a complete nitrous buildup with the Venom 2000 nitrous kit...well about the time I was struggling with this issue, VenomSVT's nitrous kit malfunctioned, causing his spark plugs to disintigrate and almost caused catastrophic engine failure. My goal was to build a low 14 sec/high 13 sec CSVT which would necessitate a 125-150 shot of nitrous on the top end....to have this much nitrous without a dead reliable fuel system (which I was also going to upgrade) and timing/ignition system would spell disaster.

So, after being frustrated and seeing others having no luck either, I abandoned the project and just bought a car that would get me to the 13's without much worry...yeah, I caved, but boy oh boy the stang is soooo much fun!

Anyway, if Kaiser has gotten one to work that's awesome!!!! I know I loved the way the duratec revved and sounded when it hit the chatter box (low RPM rev limiter)...very cool mod if it could work...I just know that bnoon and Buckshot and myself have all had 0 luck with it...and judging by buckshot's unfortunate dyno day, I made the right choice for myself...my motor would have probably done the same meltdown when I hit the happy juice.

Anyway, here's a quick picture of the MSD installed if you wanted an idea about where to place the unit if you go with it....having it right there in the engine bay makes it easy to work with and tune...



hope this helps...let us know.

i have some questions if anyone cares to help,
i will be putting my dis-4 back in, i took it out cause the dealership said that was causing problems (it wasent), anyways i need it to retard timing for happy juice, i was wondering

A: how do you advance timing with it?? i looked through the manual a million times and never saw anything for advancing timing, only retarding it..

B: whats the soft rev limiter?? i feel really clueless about something i have owned for 6 months

Thanks for the reply, I really appreciate it!! I'm certainly not having luck with me Jacob's. Might be time to do something.

Hey man, you have to get a separate plug in module to advance timing...the box itself only retards it for boost/nitrous, etc..

Also, a soft rev limiter is a rev limiter that doesn't cut fuel off, causing the engine to stop and then start when it hits a hard rev limiter. The MSD box drops one cylinder at a time randomly to prevent the motor from revving higher, rather than shutting off the fuel...shutting off fuel under boost = VERY BAD. The resulting sound of the MSD dropping one cylinder at a time is the chatterbox sound...like when an outlaw car stages....
