fuel starvation with 1/2 tank....

Was getting cut out at the turn around on course yesterday. Oil temps were at 220 starting the run, 245 at the end....thought I was getting some momentary limp mode, but after reading fuel starvation posts this morning, I'm convinced it wasn't limp mode, but fuel starvation...with 1/2 tank of gas!

Looks like I need to add more weight in the rear.....people have gotten it with as much as 3/4 of a tank on the track

Welcome to the fuel starvation club! For a typical auto-x course as long as I keep it just above 1/2 I'm fine. On the track it can cut out at 3/4 because of the longer corners.

Limp mode doesn't kick in until 280, and I've regularly reached 260 during a run during the summer. Turning on the A/C at the end of the run kicks on the extra cooling fan which seems to help speed up the cool down.

When it was happening, I started thinking about the quickest way to cool things down, and was wondering if the temp would come down quicker with the engine running or turned off (hood open of course).....so I'll have to keep the A/C mode in mind at the ProSolo when the runs come quicker!

I remember running my Honda's with the fuel light on and never got starvation...oh well, I'd rather have fuel starvation than limp mode so am glad it turned out to be an easy fix
