it will all be on e85, I'm going for 750+, so i wanted a daily setting in 400-500 range, I was planning on limiting 1st and 2nd anyway, thanks for the pic a51 ap1, camuman how would this switch be used? like what is being done in the ems?

 

This is pretty easy. Since it's all one fuel. Car is tuned to max power. Then tune at different boost points. And u set up a switch for low an hi boost. In addition u do a speed based boost setting. So like 10-12 psi too 40 mph then full boost on lol. If ur tires can hold.

The switch just tells the map to tell the boost solenoid low or hi boost. That's it.

750 is no flipping joke. Get some drag radials son.

 

I really have been wanting to set up a switch to go back and forth from E85 to 91. Anyone know what the wiring is specifically?

 

This I a lilting different. The switch for u would jump between the nitrous map and the default map. That way u could switch on the fly and not have to load different maps. Still very easy. U wire a switch to the d plug on the ems. Look in manual so u can see which pin to wire too. This is what I did so I could run meth in my car. When I hit switch I ran different ignition/ fuel map when I sprayed meth.

 

thanks for the info camuman

 

And it worked without hiccups?

 

Sorry to bring this back from the dead, but doesn't not being able to adjust timing essentially take away one of the biggest perks of ethanol? I mean, one of its main advantages is being able to run more timing (and thus make more power), correct?

Is there no engine mamagement system for the S2000 that can store two complete timing and fuel maps thus allowing to switch between them on the fly (via a sensor or switch)?
