shaunv74 03-19-2008 12:09 AM

Sweet!

Check with MazdaManiac. He can probably PM you with the instructions. I believe they are also available for download on his site.
www.mazdamaniac.com

Bring it with you to the dyno day on Saturday and do a run with the stock map and one with the Cobb map and post it up for us!

SkyLee 03-19-2008 01:10 AM

yes i will thanks man!

shaunv74 03-19-2008 10:16 AM

Also Nemesis8 just installed his and he will be at the dyno day this weekend.

Nemesis8 03-19-2008 11:56 AM

I thought it was scheduled for March 29th?

:uhh:

Yep - I have mine installed and running. Been going at it slowly. No WOT runs yet. I am data logging tonight, so I will be adding input into Jeff's thread.

kristopher_d 03-19-2008 01:19 PM

It is the 29th. Shaun's just really excited to see your dyno numbers, so he thought he'd trick you into getting on the rollers early. ;)

Nemesis8 03-19-2008 01:27 PM

LOL - here I'm posting in SkyLee's AP thread about the dyno, and he is posting in the dyno thread about the AP...

shaunv74 03-19-2008 02:38 PM

Yes!! Victory is mine!! I have successfully confused both of you!!:lol:

Sorry about that. I had my dates and time continuum mixed up. I meant the 29th when you all get together.

Nemesis8 03-19-2008 02:44 PM

A mystery, wrapped in an enigma, coated in a conundrum, basted with a paradox and garnished with uncertainty…

Razz1 03-19-2008 03:14 PM

Mine works fine!

MAF at full load is now:

6k 13.0 7k 13.6 8k 13.5 9k 12.1

Full throttle has gone from 16.5-16.9 to 12.1 to 12.5

mysql 03-19-2008 03:34 PM

what did you change?

Nemesis8 03-19-2008 04:04 PM

Yes tell us here, there, and everywhere

Razz1 03-19-2008 09:37 PM

Went to MAP 1b

SkyLee 03-20-2008 12:24 AM

Nemesis8 do i get a Map from Jeff when i get my AP? i dont know what to do.

Nemesis8 03-20-2008 12:32 AM

1) Did you purchase your AP from MazdaManiac?

SkyLee 03-20-2008 12:40 AM

Yes!!!

Nemesis8 03-20-2008 12:45 AM

2) Did you get the flash files as a ZIP attachment to an e-mail from Jeff?

SkyLee 03-20-2008 12:48 AM

no i did not get that can you give me a call 425-773-1418 thanks.

SkyLee 03-20-2008 12:57 AM

i e-mailed him but didnt get anything so far

Razz1 03-20-2008 08:10 PM

SkyLee please let me know what your base is with the AP map.

I want to compare to mine. You have the MS and I have the RB intake plus Ram duct.

I want to assume we are equal. I think mine flows more and is leaner than yours with the base AP map.

I liked the base AP map except it was way too lean on top end full throttle.

SkyLee 03-20-2008 11:56 PM

Nemesis8 then which one do i get??? dont do the flies you send me?

Nemesis8 03-21-2008 08:14 AM

No, wait for Jeff to send you your files. You can however run the Cobb files.

SkyLee 03-21-2008 12:06 PM

did you tell him to e-mail me?

mysql 03-21-2008 12:10 PM

skylee, are you able to read replies? cause you seem to be missing a lot.

MazdaManiac 03-21-2008 12:10 PM

SkyLee -

I've sent you your calibrations twice now.
Your e-mail server might be blocking me.
I'll try again in a few minutes.

Nemesis8 03-21-2008 12:12 PM

Thanks Jeff - I think it's his server.

SkyLee 03-21-2008 12:20 PM

THanks Jeff i got them!!! which one do i use first??

Nemesis8 03-21-2008 12:24 PM

MM 2004 MT NA v1_0.ptm

Please read your e-mail very closely. You seem to be jumping ahead of yourself...

kristopher_d 03-21-2008 12:32 PM

Sky, we talked about this yesterday morning. Start with 1.0. Let the trims stabalize over several full drive cycles (warm up to full operating temp, drive, shutdown and allow to cool). Then adjust per the matrix you IM'd to me. If you were able to get 1.0 on the car yesterday, we might be able to make and adjustment on Sunday.

MazdaManiac 03-21-2008 12:38 PM

Instructions:


I've attached 3 ZIP files with 11 calibrations inside each.

Save all of the files onto your AccessPORT with the AP Manager.
When you "install" the AP, select "MM 200x MT NA v1_0.ptm" as your starting map.
Start the car and while it warms up, select "live data" on the AP an scroll through the options until you get to "short term fuel trim".
Watch that value and, once the car is nearly warmed up, take it around the block.
If the STFT is a negative value, you will use one of the files that end in "b". If it is a positive value, you will use a file that ends in "a".
the last number before the letter in the file name corresponds to the amount of fuel trim you want to remove. here is the breakdown:

MM 200x MT NA v1_0.ptm - start file, no trim
MM 200x MT NA v1_1a.ptm - adds 2%
MM 200x MT NA v1_2a.ptm - adds 4%
MM 200x MT NA v1_3a.ptm - adds 6%
MM 200x MT NA v1_4a.ptm - adds 8%
MM 200x MT NA v1_5a.ptm - adds 10%
MM 200x MT NA v1_1b.ptm - subtracts 2%
MM 200x MT NA v1_2b.ptm - subtracts 4%
MM 200x MT NA v1_3b.ptm - subtracts 6%
MM 200x MT NA v1_4b.ptm - subtracts 8%
MM 200x MT NA v1_5b.ptm - subtracts 10%

If the fuel trim is off the scale in one direction or another, let me know and I'll make adjustments.
Once the idle trim is correct (a few % one way or another is totally no big deal - in fact, up to 12% is acceptable since the PCM can go up to 22% before it starts to struggle), drive around in various conditions less that high load and see if the fuel trims stay within +/-6% or so of the idle trim.
If so, you are good to go!

Watch your A/Fs at high load. If they start to swing too lean or too rich, let me know.
You should be seeing high 13's in some conditions, mid 13's in most conditions and high 12's in others.

Once you are comfortable with these, you can move up to the "Level II" flashes for more power (and more heat and then the "Level III" for maximum power.
Watch your A/Fs through the "equivalence ratio" display in live data.
If you have any bogging or sluggishness, let me know the range and the A/F at that point.

Expect to see updated files from time to time and let me know if you have any issues.

Razz1 03-21-2008 07:20 PM

HEY!

That's the same exact wording I got!

Whats up w/da jig?

SkyLee 03-22-2008 01:29 AM

What does?

Nemesis8 03-24-2008 09:25 AM

SkyLee, looks like I'm not making the dyno - sheet rocking the attic that day. Sorry guys, you will have to catch me at the NW Rotor Rally for a one on one.

kristopher_d 03-24-2008 11:17 AM

Sky, do you have a laptop? If you do, try to make a trip down to Redmond sometime this week and we'll have a go at it.

SkyLee 03-26-2008 01:12 AM

OK guys its working!!!!!!!!!!!!!!!!!!!!! here i come dyno!!!

MazdaManiac 03-26-2008 01:15 AM

I'm still trying to figure out how you ended up with a 2005 California PCM in your 2004 Federal model!

kristopher_d 03-26-2008 10:49 AM

Glad you got it working. What was the fix.

Nemesis8 03-26-2008 10:59 AM

^ What Jeff posted above you

SkyLee 03-26-2008 11:15 AM

well i got this car used you see so i dont know what happened to it

MazdaManiac 03-26-2008 01:15 PM

Its kinda interesting, actually.

I'm not sure how the law works, but I'm pretty certain that had it been the other way (a Federal PCM in a Cali car) some CARB ruling would have been violated.
I suspect your PCM was bricked at some point - either in an accident or a dealer mishap or through the action of the previous owner - and they just replaced it with what was at hand.

That answers the question as to whether the PCMs are interoperable.
