What's the predicted usefulness of the knock sensing setup in the MSPNP2?
I'd really like to add some knocksensing awsomeness when I get my 11+:1 VVT engine back into the car (I need every safety measure I can think of, I don't trust myself as a tuner/user).

I still have some space in the DIYPNP box so a copy of the circuit would fit I guess.

if you can get a schematic for it...

True, but if it's useful (and maybe even present useful results with the 99+ OEM sensor) a separate board could maybe be envisioned?

If it works, I don't have a problem with a decently priced kit. I would however prefer a kit for internal use, but a separate box would be ok too.

What compontents need to be added to the diypnp to make it as funtional as the mspnp2 other than the more complete knock sensor?
I saw the Low imp injectors will work anything else I should consider before pulling the trigger today on a diypnp?

without knowing what the MSPNP2 actually has, for a 90-93, nothing.

Thank you, but we have implemented this with hardware already. The code mod would probably take some changes to the hardware as well.

Hard to give an absolute number, but our goal was to create something better than the MS1/Extra circuit (pretty sure we've hit that goal) and KnockSenseMS (quite likely), but didn't have the resources to make anything in the same league as the J&S Safeguard or some of the things being tested for MS3.
