So, as the title says.
Do these multi spark systems work with DJet? If so, are there improvements? I am not looking for more power, but more MPG...more efficient burn. Rich |

I have seen a bolt in twin spark type 4 dizzy.
Unfortuneately I have no idea why its maker hasn't brought it to market yet. (Might be because there aren't many twin spark motors) It would be compatible with with DJet no problems. |

I think he's referring to MSD systems, such as the MSD analog box and the Mallory Hyfire VIA MSD box.
Yes, they help. Provide a much better controlled spark, multiple sparks (4) under 2800 RPMs. |

I'm an MSD believer... Running a Hyfire VIA box and loving it.

A very good BANG for the buck, You should feel it in proformance. Make sure to gap the plugs about 45.
My cars seem to run cooler with the MSD and fuel pressure at 32psi. |

Did any of you experience better mileage, or more power on the track?
I am looking for better mileage. Also, can MSD use ignition points? I wont go to a petronix...to flaky. Rich |

I had a Mallory Hyfire on my Djet and it just would not idle evenly. It would surge and then die. I spent many painful hours using a variety of adjustments. Sent it back to Mallory, as I thought it was defective. The replacement did the same thing. I was using their recommended coil too. I'd like to hear if anyone had better luck with MSD and Djet

Looking at doing the same, keeping the points and using one of the MSD Boxes.
Seems to be alot to choose from; 1. MSD 5520 - MSD Street Fire Ignition $149.99 Jegs 2. MSD 5-Series Ignition 109.99 Jegs 3. MSD 6-Series Ignition 184.99 Jegs 4. Jacobs Ignition ULTRA TEAM VW BUG 255.99 5. Hyfire 6A Ignition 141.00 6.Crane Cams HI-6 Ignition & LX92 Coil Kit 339.99 7. Universal Kit with Super Coil #110-140019 227.99 Etc, etc, etc. What has been used for stock D-Jet or L-Jet and worked well? Thanks Smitty |

Mine works good with the stock l-jet. No probs. I am using their tach adapter though, otherwise it the injection doesn't work.

Seems to me that Djet is using the trigger point for the FI...these are mechanically activated so as long as that part of the distributor remains, no tach signal will matter...but I assume.
The points worry me due to the fact that even now they tend to get pitted after 2-4k miles. They are cheap enough to replace, but I worry that with multiple sparks it may accelerate the process. Rich |

Interesting article that says points are ok, but says nothing about djet...

Why would you stay with points? It seems an odd mix of new & old technology. How about a Pertronix? Orrrr, doesn't MSD provide an electronic points replacement?
I've been using Pertronix for about 15 months and never had a problem. With MSD I'm told you don't need the tach adapter for the engine to spark correctly (2.0L D-Jet), but you need the adapter for the tachometer to work (kinda makes sense) (IMG:style_emoticons/default/idea.gif) . |

From what I have learned about Petronix there is one benefit. Pro...no longer need to adjust points, or set dwell. This is part of a tune up, so its a good time for me to listen to the car and see how things are going. Con, when they die (petronix) you are left stranded on the side of the road with no solution. They cost alot. I can buy alot of points for what petronix costs. It does nothing to improve the performance of the engine, it just eliminates the effort it takes to set up your points correctly. I like doing that. Overall, if I have an issue with my $7 dollar set of points (two per year, so $14 per year), I reach in the glove box, put in a new set, use a matchbook (or even by eye) to set the gap and I can get home to my tools. With petronix..call a tow truck. BTW, I have never ever ever had a set of point leave me on the side of the road...ever. They dont die...they wear out sure...but so do my shoes...I know when the point are wearing out..I can feel the performance degrade. Rich |

pertronix + Multi-spark box = flawless operation.
Did anyone make it so you could use the mallory unilite with trigger points yet for djet? IIRC - SOMEONE was working on it (IMG:style_emoticons/default/smile.gif) |

The reason the points pit is the current flows thru them to operate the coil. With MSD using point only a very small current flows thru the points to signal the MSD unit. The current thru the coil is done by the MSD unit. The rubbing block for the points will still wear so the will still need periodic adjustment/replacement.
I don't know if the MSD will interfere with the D-jet or L-jet systems, one or both use the tach signal from the points to determine if the fuel pump should be energized or not. MSD can work with points or a mag pick-up, they also provide wiring diagram to wire in an ignition kill switch by grounding one of the signal wires. I am hoping the MSD I just installed on my old RV will drop my idle HCs just a little so I can get passed smog again. I figured I had is sitting around I could try it. Jim |

Rich When I use a pertronix, I keep a known good distributor in the trunk all set up and ready to go. One 11mm wrench, a little timing by ear and you're back on the road again and on your way home to the garage. |

A condensor may have...but not points unless the contact fell off the point...then you really should have looked at them a bit sooner. You keep a whole petronix and distributor in the trunk? So you have two petronix systems??? lol Points fit in my glovebox.... Rich |
