Anyone using 0411 Standalone to control 4L80

[TyeJo]

Thanks, looked at balancer options and may have to go this way. Keeping the stock old school V-Belt drive system so the reluctor would have to mount in front of the pulleys. Looking at all options, really hoping for someone that has successfully used HEI/Coil system so as not to require many mods.

Maybe the HEI Distributor Pickup Coil can supply two ignition modules, one output to the 4 pin ignition module in the HEI distributor and one output to an externally mounted 7 Pin EFI ignition module. Perhaps the 7 Pin EFI Ignition Module will provide a 0 volt ~ 5 volt square wave RPM output signal?

Thanks, agree the Holley cover might be the best option. Was really hoping to convert/use the HEI tach signal as I only need trans control and no EFI/Ignition

I have used the Howell EFI swap which uses a modified tach signal. The system seemed more reliable after being changed to use a proper square wave signal generated by a GM ignition module.

HEI distributors with 4 pin HEI module can be converted to 7 pin HEI module. 7 pin HEI module supplies a REFerence signal just like the one the 7427 is designed to work with.

Note that you do not need to secure the weights or vacuum advance because you are not using the computer to control timing.
