No I have a carburated blown motors.

I use to be a bigger fan of DS but not sure anymore about it. I do know for a fact that the EST distributor DS is selling currently comes from China or Taiwan -- one of those I forgot which place. On their page they state all USA built. Not sure about that but will find out

They are not the same company as a couple years ago. Just saying

You can hook an MSD box to TB IV set up https://www.offshoreonly.com/forums/...erbolt-iv.html

I would only do this if you are having issues with fouling plugs though or want to change/add a rev limiter.
If you just want a different timing curve, then I'd look for a different TB IV module. IMO, the V8-HP has the best timing curve for most performance apps.

I don't think I need it at all, what would be nice is a knock sensor though.

Sounds like a plan. It’s what whatever makes you comfortable. Sounds like your staying away from ign controls but just wanted to let it be known Daytona Sensors is based out of south Daytona FL and manufactured and assembled is US. Unless as of recent.

So does there ignition controls also offer a knock sensor? I'm not against them. That was the point of my original post. is there a reason that would be beneficial.

I opoligize for getting off the track. My bad and your correct. I didn't direct the post to your original thread. That does happen and I don't like it either.

I wasn't being critical and I appreciate the information. That is why I come here, sharing of knowledge.

with daytona you can use a map sensor and pull timing under boost, make a 3D timing table, there’s idle stabilization, start retard, rev limiter. There’s a lot of nice benefits with it. I run them and use the start retard and idle stabilization, rev limiter.

Well said. Was covered already from another aftermarket ignition thread started by OP in January so I figured he knew.

Personally I wouldn’t be without ignition control especially on an SC build. To many benefits.
