I don't know what the JMS chip is, but Daytona Sensors makes good stuff. either the CD1 or CD3 will do wonders.

JMS Chip is a company.

Looks like Daytona Sensors is now a part of it

Don’t know I’m confused now. Called Daytona and they said they only changed the decal . For me box is totally different.

someone did MSD DIS
like this ?

I went for Daytona sensor CD1 and can’t be happier. Starting perfect , idling perfect and runs much better !!

thanks guys for your advice

glad to hear!

I’ve had a CD-1 in operation for several years.
no issues.
