Fuel Pressure Monitor

Postby RocksteadyRacing » Tue Feb 14, 2017 9:01 am

I've been looking at different Data logging packages and a lot of them have a fuel pressure sensor, but I can't figure how why I would want to know that for any reason other than tuning or diagnostics. Is there any on track scenario where this would be beneficial? I can't see it being a good indicator that you're almost out of gas. Anyone have any ideas?

Agreed. For diagnostics, this would be huge when answering the does it have fuel / spark / air diagnostic method. Can't seem to find a reason why this would matter for race strategy, etc.

Low fuel or fuel not available to pickup in long corner. Can make the car run lean and melt a piston, ask us how we know this!

The Crown Vic at Brainerd running Donnybrooke - the long, long, long right hander after the drag strip ended its day.

Car had a fuel cell with a center pickup but was getting enough fuel to keep running just got too lean.

Fuel mix under race conditions can vary versus the dyno, plus what they said about running lean. A Miata will start to run lean if the alternator goes bad and starts to run off of the battery only so be sure and monitor that too :)

We have been running a fuel pressure gauge on the outside of the windshield but in view of the driver. It's useful when trouble shooting problems on and off track and is a good early warning that we are running low on gas.

Thanks for reminding me. I ended up getting a fuel pressure sensor in a kit I bought. We'll see how much "value add" there is for me after a few races.
