Modded DSM owners probably know why this is important and is not a mod that needs to be done on the Evo (yeah!) If you have no idea of the implication of how indirect power supply and the resulting voltage drop effect fuel pump output, you should do a web search, but here's a hint: 15%-20% flow change between 12V and 14V! * The fuel pump is relay powered directly from the battery. * The fuel pump gets fuel itself directly from its side of the tank, as well as the opposite chamber via a 'suction hose'. * There are TWO fuel level senders, one for each side of the saddle-type fuel tank.

The stock pump is fine for bolt-on mods (air filter, exhaust, etc.) and increased boost, but when you begin really opening up the air flow with cams, even higher boost, or are closing in on the 325+ wheel HP mark and are looking for more, we really think that warrants the upgrade.Ī few tidbits about the Evo fuel pump/tank: For a little over $100 and 30 minutes of your time, it is quick and cheap insurance against catastrophic lean conditions.Īt what point should you replace your stock pump? Like we said, it's always best to err on the side of rich and make sure fuel volume available for use is more than you need. They are quiet (even more so in Evos), supply enough volume of fuel for nearly 500 wheel HP with the correct injectors/tuning, but are reliable enough for daily drivers. The Walbro 255lph fuel pump is the choice of many and we've used them for years. As always the best practice, we recommend upgrading fuel pumps before you 'need' it. If your setup requires more fuel for a knock-free tune than your pump can supply, no amount of fuel tuning is going to help you and unless you turn down the boost, you could be on your way to a big problem. Note that fuel supply is NOT fuel delivered to the cylinders, but fuel available to be delivered to the cylinders.

I spent a good amount of time searching for tips on this car and aside from Praiano's tune I didn't find much.Although the stock Evolution fuel pump will suffice for most 'bolt on' mods, at some point in your modification path, you will want to upgrade the fuel pump to make sure that you never run out of fuel to supply to the cylinders. Using these settings, I was able to take 1st place in every race.īraking Sensitivity reduced to 20 (drastically improved control on decel) These adjustments made a huge difference and pretty much eliminated the oversteer and traction loss I was having.

This tune is based on Praiano63's tune with a few changes. I had major problems with oversteer and loss of traction on decel which would constantly make me spin out. My first attempt at the Championship using this car (Deep Forest Raceway) was a disaster.

I was lucky enough to win the Audi R8 LMS Evo 19 from a roulette ticket (the only time I've ever won something other than the smallest of coins.) and I always try to use the cars I have at my disposal rather than buy one. I'm probably getting into this game a little late compared to most of you, but this might help some other people out who have not unlocked the Gr.
