FPR questions and wideband

Ive just got my innovate lc-1 connected to my laptop to datalog my air/fuel ratio.
Ive also just noticed my fpr vacuum pipe was split and waht looked to be like hardened silicone inside the pipe for the fpr?
Ive dug this out and connected pipe up but wanted to check the fpr was working. If i unplug the fpr vacuum, will the difference show on the wideband gauge?

Should do, as the fpr won't be increasing and decreasing the fuel pressure as the manifold pressure increases and decreases. It should show the engin running lean with boost.

And you'll have a manifold air leak where the fpr pipe is disconnected.

If you unplug the FPR at idle, the AFR will go schitt rich if the lambda can't pull back the fuelling.

ok il give it a try tomorrow
