Question is about fuel starvation. What is the consequence (or car behavior) from the fuel starve? I will give some detail on what I experienced a few days ago.

I was accelerating up an on ramp to the interstate, was in 4th gear rolling onto the throttle and coming out of it planted. About 50 feet into the straight at 5k rpms it reacted like I hit rev limiter. Vitals looked great so after a mile or so I done a WOT in 4th again and it did not happen.

Later I took another right turn but much shorter maybe a 80 degree 100-125 FT turn. Same thing as I came into the straight around 5k rpms it acted like I hit the rev limiter. I played around all the way home and it did not do it again. Only after these right turns.

That said, I know a long sweeping right turn causes issues. What are the issues exactly (fuel cut car reaction)? Does it hit you while in the corner? Or in my instance's I was in and out of the corner quickly so the lag hit me as I was coming into the straight?

I had a couple dots over a quarter of a tank of fuel remaining, also the car is TT.
Thanks for any input I will rep when it recharges I ran out for the day!

This is fuel starvation all the way. Tomorrow I will right a detailed response... This is difficult to do from my iPhone!

Thanks so much! That keeps me at ease at least. I may purchase this in the future because I may track this car one day.

Question for those of you that have made this modification (Spohn, Mike, et al) what are your lap times before/after the fix?

no different, just get to do a lot more laps per fillup.

So you haven't gone around with <1 gallon to see how much time you'd save?

It will be cool once this solution has been thoroughly tested by track drivers who have had fuel starve issues and to see how low people can go without an issue.

Does this product carry a warranty? And curious if you install this will it void manufactures warranty if it were to impact fuel air ratio and cause engine failure? That's probably important for people with cars still under warranty to know.

as stated before me, it has been tested to a completely empty fuel tank on the road course.

As for a warranty? Well, I have never stated one.. but sure I will gladly warranty it. There is actually no need to warranty it since it is almost entirely a solid state device that could never possibly wear out, except for the Walbro fuel pump that resides within it. This pump I would warranty within reason, as fuel pumps wear out and fail eventually no matter what. If someone tells me 2 weeks later it died, ya I will replace that.

It will not impact fuel/air ratios... well, except when youre making a hard right turn, you will no longer lean out the engine to the point that it cannot stay running. The factory fuel pressure regulator is still utilized, and with no change in fuel pressure, there is no change in A/F.
