Fuel Pressure for JRSC (10 psi)

[sullust]

One more thing: Would the TPS Hack and the MAP mod interfere with each other at all when your off boost? Or the JR BTC when your on boost for that matter?

Thanks,
Dave

Holden, on the TPS hack what happens when the ecu uses the WOT fuel map without the throttle nessesarily being at WOT? Also, should everyone use this hack or should you only use it under certain conditions? (such as 10psi when your injectors are about maxed out)<HR></BLOCKQUOTE>

When the ECU goes open loop (to the WOT fuel maps) it stops trying to adjust injector duty cycle to maintain a "clean" mix (you know how the AF bobs from lean to stoich?). So you stay on the "power/rich" maps and the ECU doesn't fight the RR FPR.

Boosting with the ECU still aiming for a stoich mix is where most detonation happens.

I think every supercharged Honda should do this. Before I put it on, I either drove gently or crazy. After the mod, the middle of the gas pedal became safely usable again.

The MAP mod is supposed to be a more elegant solution than the TPS mod for the same problem. I don't know what they would do together.

The TPS mod is only $10 though.

One good side effect of the TPS mod is if you are using a J&S Safeguard, it will arm at 1psi boost instead of only when at WOT.

It does nothing with the BTC.

Holden, I can's seem to find the TPS Hack mod in the archives. Could you possibly help me out on this one?
