Car is running Fantastic
Brought the car out from storage and it has been running great.
I just got done doing the following: - Updated/Wasinger Fuel Regulator - New Spark Plugs 41-801 this time - Replaced coils - New Custom Ignition Module Need to change oil and swap the fuel filter along with doing an alternator upgrade with associated wiring and I will be all set

Re: Car is running Fantastic
Good to hear Jeff. I'm running strong also. Still getting use to the yellow. I am going to do a dyno run soon to see what this combo does.
I also got my orange taillights to swap into the euro taillights look. |

Re: Car is running Fantastic
Jeff,
What are u meaning about a “custom ignition module”? Have u modified the stock ICM? Inquiring minds want to know. What ignition coils are u using? |

The Stock harness is not cut, I ran a new wire to the crank sensor and just found a mate connector so will change to that and remove the added wiring. I repinned one wire @ the ECM and ran it to the empty spot on the diagnostic connector. the new module then plugs into the diagnostic connector. I truly think the car runs better overall, seems much smoother. the new module is not high power, it jut is a controller for the LS Coils so it takes a very low amount of current 300mA max I believe the only downside is the unit needs to get installed in the cabin as the components are not all the higher temp ( Military spec), most or Industrial

Re: Car is running Fantastic
WOW! That sounds like exactly the kind of solution our cars could use. I like the idea of using the LS type coils and having one coil per cylinder even if it runs “waste spark”. I would think it may have benefit in the higher rpm range in particular.

Re: Car is running Fantastic
Nice work, Jeff. I applaud this effort. Does the tacho work? What about the serial RPM stream? All of that is produced, I think, by the factory module.

This is the IM mounted, I orderd the mounting brackets and they sent blue instead of silver, but they still work to mount it..lol. Earlier picture of testing below IMG_0032.JPG Needed to confirm it worked before going through the effort of mounting everything.

Re: Car is running Fantastic
Love it when a plan comes together. Thanks Jeff. A fascinating alternative, and actually a better one than the stock ICM.
