Default Fuel pressure logging

S2000
Walbro
stock rail
stock regulator
ID 1000's
AEM sender
KPro III

Sender is welded to the end of the fuel rail. Here's what the log looks like:



Is it supposed to be choppy and all over the place like this?

You probably don't any type of damper on the rail?

This is a s2k. IIRC, there's a stock dampener on the rail. I'll snap a pic when I get home.

im willing to bet a regulator which is able to bypass more fuel will provide a smoother graph

I would be willing to bet it has a lot to do with your stock dampener and or regulator. What size walbro are you running?

No and no idea. This is all we get



Before I ask Hondata if there's something they can do about it, I wanted to figure out if this is a mechanical anomaly first with my setup. Pic of the sender mounted on the rail:

Throw another map sensor on that channel and see if you still get the rocky mountains. Or, try that sender on the oil pressure. That might help narrow things down...

I have an oil pressure sender that I'm wiring in as well. Eveything is in place, just have to finish wiring it up

I didnt need the Motec log to tell me that I'm a shitty driver, but it definately reinforces the belief..
