I have a 2008 s2k mase boosted, with hondata flashpro,
and I have a regularly tuned calibration running for pump gas

I would like to retune the car, and create and save another calibration map for race fuel during track events, etc.

Would there be any problem with this?
And if there isn't, my second question is:

is there a way to completely empty remaining fuel in the s2k?

(This way when I'm at a pump station I can completely change from 93O to race fuel and load the new calibration for race fuel with my little laptop on the spot)

I'm a slight noob so give me the rundown of any problems (if any) I may face, and whether this is practical and/or a good idea or not...

thanks!

 

more power = bigger chance to break stuff. otherwise, should be fun, mase kit + race gas = more fun.

what did you make on pump?

 

I would just ask Mase to send you a new version of his tune for XXX octane, and I'm sure he could just alter the fuel and ignition maps by X %, and send it back to you. If you just make sure the tank is almost empty (with good planning) before going to the track, then you should be fine.

 

428whp at the pump

 

ok sounds good. but is there any way to empty the gas tank on the s2k?

(my dilemma would obviously be mixing octane- i would want the tune to be perfect)

 

I don't know how easy it is to empty the gas tank. There may be a drain plug on the bottom, but I don't recall seeing one. I understand how easy it to to get all OCD on it, but I really think draining the tank is excessive. If you mix 1 gallon of 93 with 12 gallons of 100+ octacne, then the mixture would be 99.X. That's not enough of a difference to worry about. There is also no such thing as a "perfect tune". The best you can do is "really good".

 

Ok... And what octane level is the average racing fuel?

(I'm still gonna be rocking the stock exhaust if I do this btw lol)

 

/\/\
it just depends on what's available where you buy it.

and if you have several available, 100 will be cheaper than say 105 or 110.

 

after researching,
it looks like my practical choice according to availabilty and location in my area will be the sunoco 110octane leaded racing fuel. has anyone used this fuel before? i need as much 411 and opinions on it as possible, and the risks of running leaded fuel...

 

The only problem that I know of with leaded fuel is that it will damage the catalytic converter.
