I'm really looking forward to what kind of power gain you get from this.

You were supposed to bring the car with my hoist and tools in the trunk so I can here this beast...........enjoy a bill is in the mail.

Congrats on getting it running man. Gonna have to set up a meet so we can see this bad boy in person. My car is torn down right now, so I don't know when the next meet is gonna be, but I will post it up on here when I figure out.

sounds good. did you make it to Deals Gap? if so, how did it perform overall?

reddozen · 05-02-2011, 12:09 PM

made it out there fine. it runs great. most of the lope is gone after kane tuned the idle and closed loop maps, but it feels pretty strong so far. I just have to work on tuning the open loop and higher RPM ranges.

SSV and VDI fixed and working... It pulls harder than I imagined it would. Butt dyno says it's similar to my friends 260HP MR2...

Now to figure out the surging idle, finish tuning and dyno.

A dyno is a must

... for the idle, did you bump your neutral switch or clutch switch during all the work or maybe its just bad (TSB from mazda on neutral switches)...

I'm pretty sure that's what it is, but I'm trying to eliminate everything else before spending money on it.

I would figure the surging idle is from the port job. That's how mine was. Actually both the last two times I've replaced the engine I've gone to a bigger port than before and each time it hunted for idle. If it's the same for you, I believe the tune itself should take care of it, maybe some minor adjustments to the idle screw also (if you have one, not sure how idle adjustments are set up for the RX-8).

Naa, the factory computer for the RX8 is probably one of the best ECUs ever created... the idle only starts surging after driving, or if it gets really hot. Since I got the SSV and VDI fixed, it does it less, and to less of an extreme, so I'm sure that was a lot of the issue.

Going to try setting the idle back to 1200 RPM tonight and see what happens.

Does the searching idle go away if you depress the clutch pedal?

nope, but it's very mild now that i've fixed the valves.

Oh OK, I thought it surged right at start up. Nevermind.

Valves? I thought it was a rotary?? LOL

SSV and VDI are valves...
Not in the piston engine since, but they direct the aux port air flow...
