Just need to know: Cold air intake on mine, I buy an AP from MM, out of the box what do I need to do? Thanks much.

The coil issue is with the new mozsport ignition upgrade, if your stock no need to worry. As for the CAI, I have the MS CAI and have had no issues with MM's maps. Though I did have issues with the Cobb stage 1 map.

The thing to keep in mind is that you're not changing anything on your car with the AP. Your hardware that works today, will be used exactly the same once you flash with the AP. The only thing that changes is the map used in your PCM.

So if it works now, it should work after. If not, talk to Jeff and he can fix it.

The FI people had problems because most of our systems used to be MAP based once the car got into boost. MAP mode doesn't use the MAF sensor, so it didn't really matter how our intakes were setup. Once we were using MAF 100% of the time, the airflow across the MAF sensor mattered, and if not setup properly, the car assumed a LOT of air flowed and we ended up with a rich (safe) AFR in boost.

You need screens on your intake before the MAF sensor to even out the flow to prevent problems...some intakes can get away with a single screen...but I think intake flow is probably going to be your biggest problem...and the AP cannot correct for that...its a mechanical issue...

Got the new map this morning
will try it out today.
big thanks

Psychofox 05-09-2008 05:00 PM

MM,
Can you send me the 3V series with the dwell adjusted
the car is too lean with the 5V map and a screen installed before the MAF
. i am getting high to mid 12's under boost with that .
I also emailed ya
Thanks

MazdaManiac 05-09-2008 05:12 PM

Sure.
Did we ever run the 5_0 maps on your car on the dyno?

Psychofox 05-09-2008 05:38 PM

I dont know if you tried other 5v maps but the last one shown on my AP was 5v_6a. I think you made some tunes on that map. The unstable ilding was becuase there was no screen installed that day. I just got a datalogger so I'll log somthing for you to work on~
Thanks

MazdaManiac 05-09-2008 05:43 PM

So, why do you want the v3 calibrations again?

Psychofox 05-09-2008 05:43 PM

My datalogger can only log 5 parameters at a time.
which 5 parameters are most useful for you to look at?

Psychofox 05-09-2008 05:47 PM

I just installed a screen before the MAF yesterday and with the 5v_6a map, AFR is in 12's under boost and i went back to 3v_0 and its around 11 under boost~

MazdaManiac 05-09-2008 05:53 PM

Log these:

RPM
Calculated Load
Lambda
MAF

Since "5v_6a" worked for you, I'd rather scale that map than start over with the v3 stuff.

but isnt it unsafe to drive/datalog the car with such lean AFR in boost?

Psychofox 05-11-2008 03:34 PM

MM,
I just sent you some logs, can you take a look at them

just wondering if you are getting my emails. I havent' heard from you for a while about the updates on upgrade kit, calibrations etc. Thanks! (@sfu.ca)

MazdaManiac 05-11-2008 11:15 PM

I've sent you a bunch of responses.
I'll send you a condensed version in a minute.

eviltwinkie 05-12-2008 02:43 AM

Optical TDI 05-13-2008 11:34 PM

Any dynos, real or butt?

mysql 05-14-2008 06:06 AM

devildog1679 05-14-2008 08:43 AM

There will be a few on the 7th of June.

Delicately calibrated butt-dyno reports +9 ft/lbs of torque and +10-20 whp...but +400 bhp*...

around what AFR's at WOT above 6000 rpms are you getting eviltwinkle?

Grouch 05-14-2008 08:57 PM

I got a response about the Wednesday shipping date, but none on the shipping options. I was hoping to have it sent by UPS AIR, or FedEx ground, but if it's too late, that's perfectly fine. I think we have that problem again where some emails filter yours out if you send from one of your accounts and the name doesn't match?

Can you resend anything you may have sent me? Thanks!

OK, went out today to test this...I am consistently seeing 12.9 *sometimes* and 13.9 most of the times...

Again running lean and hot...I'll upload pic of the plugs soon...

LTFT is still @ +2...going to reflash to see if I can get it down...
