DFCO in a 1990 Honda Civic STD

[aalb1]

I'm looking for confirmation to see if a 1990 Civic STD utilizes DFCO. Searching online for this feature it seems that there are some discrepancies on this.

According to this post Honda introduced this feature in 1990.

But because the 4th Gen Civic years range from 88-91 does that mean the 88 & 89 Civics didn't have DFCO? Or was it not included in the 88-91 Civics but it was introduced in the 90-93 Integras & 92-96 Civics?

If anyone can confirm this I'll be eternally grateful!
