Jeff, Sorry I wasn't able to be around last night at the end of my tuning session and missed out on the map you had ready for me. You don't happen to keep them in a file or anything and would be able to email it to me would you?? If not I will make sure I am available on the 17th for the whole night. Thanks

Good assumption. You can see this dude activate on the dyno. Also, pull the vac hose from under the black manifold and suck/blow it to see if it is activating. There is a little black snap ring on the actuation arm that can fall off----therefore it will be hooked up but when the vac triggers this it will do nothing.

thanks eric! i will take a look at it this weekend and hopefully figure out what my VDI's deal is. It has to be fixed before I do a HPDE at summit point.

EricMeyer

Another thing we've found is an engine usually looses power at peak (around 8K for us) or when the last valve actuates (7,250 for us). Does it sound weird up top? Could your engine be a little old?

I'll pm you about it rather then clogging this thread up.

Jeff,

I am new to rx8 and would like to know more about your tunes. Looked at your web site but didn't find any dynos or any specs of what different tunes do.

Blacknightz

Jeff's calibrations are CUSTOM specific to ur individual's car... Racing Beat one isnt... So what mods u have on the car... the map is cutom tailored to it...

Jeff,

Question for you. I'm on the 2nd step of the calibration, and haven't gone further since you detected the vacuum leak. I think I've got it fixed now, but I just "think" I do. Should I re-pull the original 4200rpm log for you to verify?

MazdaManiac

iTrader: (3)

Yeah - Load up the base calibration again and do both logs.

We'll be online in an hour.

RIWWP

iTrader: (2)

Understood. I won't be available to do the runs until after work (5:30pm EST at the earliest).

Blacknightz

Damnz... I fell asleep....

^ I also missed out

You know that you posted this in the same minute that he opened up for the 2nd session yesterday? And was open for 2.5 hours after that.

Not to make you feel worse or anything :/

Blacknightz

If u read earlier posts... U'll know these session would be the next day for me in the wee hours of the morning... so his first session would be 1am on 18th May 2011...

And the 2nd session would be 7am of 18th May 2011... That's a no go for me as morning traffic would already fill most of the highways here...

Hopingz to catch the next one... and do a midnightz run

Jeff,

I am sending you an e-mail (ap@mazdamaniac.com) regarding the following but I figured I would post it for S&G's...

I just bought the Cobb with the calibration service but I have a question...First here is my setup:

2005 Rx8 - 100k miles with new Mazda reman engine (2k miles on engine)
- Cobb (purchased yesterday)
- BHR ignition
- BHR Midpipe
- Greddy Exhaust
- AEM Intake (newly purchased on BHR website)
- ACT Flywheel/Clutch (shouldn't matter)
- Crazy driver with lead foot

As you can see I have a few miles so I need to make sure everything is in order before I waist your time tuning and we have issues due to old/failing parts. What should I concentrate on to make sure everything is in order?

My ideas:
- Clean injectors?
- New fuel pump? (BHR ofcourse)
- Plugs have 3k miles on them
- Throttle body cleaning (will do this either way...tooth brush and break cleaner)
- Clean MAF (should already be clean)
- Anything I am missing?

Feel free to tell me to read something if this was covered...I've been reading for the last 3 hours...LOL!

I'd say just dive in.
Unless there is something mechanically unsound (like a vacuum leak), you should be ready to go.

hey jeff, so i finally found and fixed the boost leak as i mentioned down in vegas but i'm lean now at idle (17) and not sure what it'll do under boost. should i go back to the fi base map and start over with you on tuesday or am i better off keeping the tune that's on there?

MazdaManiac

iTrader: (3)

Fixing a boost leak usually makes the car run rich.

Do you have stock injectors? If so, go back to a base map. Otherwise, the tuned calibration.

Either way, we are probably gonna have to basically start over. Carefully.

So should I log on the latest map I have? Idle and 4th to start I assume? I'll get signed up for Tuesday anyway.

MazdaManiac

iTrader: (3)

Yeah - just the idle and cruise logs to start on your current calibration.
That is, if the car runs normally on that.

We shall see..

I added the plugin for Mac but saw you requested the PC app version. Is that a requirement as well?

MazdaManiac

iTrader: (3)

PC version? All you are submitting to me are logs, so I don't care what version you use.

AP Manager works on Mac? I'm pretty sure it does not.

Looks like it does now (since 10/27/2010 apparently, per release notes):
