congratulations on getting it in, but with a week left to Deals Gap, i suspect you'll be quite busy this week. good luck. :)

Oh shit! Have it ready for this week, I want to hear it!!!!!!!!

Video of idle

That is spectacular. Sounds so good! Can't wait to see the performance aspect.

Cool. Love that idle.

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?

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...

^^^^sarcasm owns you^^^^^

On the internet!? Very likely...
:cheers2:

Yeah sorry, maybe I should have been more clear, put it in teal or something LOL.

So how is the tuning going with this? dyno numbers yet?

Over a year old, But I'm wondering if there was any numbers on this?

Last time I talked to him... The engine has over 15k on it and pulls hard.... For what it is :-)

That's great...

Did he ever mention any dyno numbers...? Or maybe you could ask him?

That engine will last forever lulz...I'll tell him to chime in.

I dont think hes dyno'd it yet? could be wrong

No dyno numbers. To actually see anything, you'd need a before an after. I have no "before" pull on any of my local dynos, so the actual power gain can't be established.

If I pulled a 180, the motor would look normal, but if i pulled a 150 before, then you could see that it was good for a 30 HP gain. Dynos are too unpredictable for me to waste $100 on a number that means nothing. I'll do it one day at a dyno day event, but I'm in no hurry to throw money away.

Another guy on 8 club with a similar setup is claiming an 80 HP gain, but I'm not sure I trust that number...

Carma is having dyno/bikini wash day July 22nd.... Put it on there, I'll pay just to see what it puts down.

We can give it a go if I'm back in town by then. I'm going out to Ohio to visit family and coming back sometime next week. It still needs more tuning, but I think it should be as good or better than stock.

I could go back and pull it again after the tunings done too.

Was there not a noticeable jump in power between stock and bridge? I am assuming you're running a different tune than stock, but with you saying it still needs tuned makes me curious if you just threw a base tune on it and went with it or tuned it at all.

It's tuned enough to run fine in closed loop around 13~14 AFR. Open loop is tuned to hold the factory AFR range. Right now it's all just tuned to be "like" stock. We'll push it further when I have time... busy with job, family, 3 websites, etc.

I understand. Hopefully you can get it tuned relatively soon and get back with us. Like you said, the power numbers don't matter much, but I'd be very interested in knowing the end result anyway.
