Does the SAFC work well with the Boomslang harness for the 1998 DX Civic? The harness will match the non-vtec ECU, yes? Just plug and play?

Anymore?

And in a DX no less?

 

Hahaha! That's funny. Almost as funny as that cute metal gas cap you have in your album for your 1998 EX.

 

Anyone have an actual answer for the OP?

 

seriously though, what do you expect to gain with an safc? people still use those?

 

Hahahaha! You could have tried it by now. Some critical thinking says there should be no issues past the fact that you're putting a SAFC on a DX like it's supposed to actually do something.
Lemme guess, "I don't actually have it yet."
And that gas cap is solid billet aluminum.

 

More relevant question for OP:

WHY?

 

To make VTEC crack harder! Wait...
