Variable speed fuel pump help

Hi,
I have a variable speed fuel pump that needs a true 0-5v input. Some of the V8 guys are just tapping off of their TPS. Can that been done with an S300? What are my options to get this to work with a S300? Any non used outputs that can proceed a 0-5?

You can try it, but there is nothing that is designed to do what you are trying. This will also probably make tuning much more difficult.

Thanks for the reply, I'm hoping I can possibly use my wideband's 0-5 if the s300 has no 0-5 outputs

That definitely will not work.

How about the nitrous/aux output?

No, that cannot be used for what you are trying to do.
