I wish the effing snow would stop over here so I can do my datalogs for my second calibration

 

And that is AFTER the Esmiril thread got deleted, taking about 2 dozen posts with it.
I keep deleting stuff, but it piles up faster than I can get rid of it.

 

hey Jeff... how recent is the avatar picture? something looks different from when I saw you back in the Fall... and no, I don't mean the dog

 

My hair grows at a rate of about 1" every 3 weeks, so I go from shiny to Sasquatch on a regular basis.
I don't know when I took that pic, but it was probably back in Spring.

 

Such speedy service!!!!

 

For the AP of my facial hair?

Your logs are excellent. Spot on - stoich in cruise and only 2% trim at idle.

 

So I sit here like a child on the eve of Christmas Eve waiting for a MazdaManiac calibration.

PS: I also realized how much I suck at wrapping christmas presents.

 

 

I didn't see my name on the list so I re-sent. No big rush since I will see you on the 17th anyhow tho

 

Me too alz0rz...

 

So true!

Jeff, I sent you a PM. I want to make sure this is the right calibration.

 

Yeah. Its my bday today too so I expect a present in the comming days Jeff!!

:D

 

So Jeff, these last set of calibrations you sent out are they still comparable to stock? or are they the "performance" calibrations?

 

What does it say at the bottom of the e-mail?

 

Oh dur. Every time I load a new map you send me, the butt dyno says the car feels quicker already! I can only hope for the best when I do get a "performance" calibration.

Happy holidays!

 

It probably is getting some power benefit since most of the calibrations I've done so far just to "dial in" have resulted in a significant correction to the target lambdas.
This next set of instructions that you have received with v4.0.2 has you do some WOT logging, so we'll see where your car sits now.

 

Looking forward to it. Did my first drive cycle this morning and the second tonight. I'll do the logging tomorrow morning if I get a chance to and you'll have logs in the evening.

 

No rush - I'm not doing any more calibrations until next week.

 

Gotcha.

When we do finish the calibration process I'd like to do a realistic dyno of any gains.

What I'd like to know is how accurate would my readings be if say I did this: Uninstalled the AP, did a pull, then loaded my final AP tune and did another pull.

Would that be sufficient for an accurate representation of a before and after?

 

Probably. There are still the effects of fuel trim (which we try to negate through this process), but it would affect both pulls.
The more accurate example would be to drive the car stock for a bit, do a pull, install the AP, drive the car and then do another pull.
I know that isn't practical, though.

 

New calibration, nice.

A question though. Seeing as I have the original cat, at what point should I worry about idle/cruise AFRs values and such, I have been monitoring them but am not sure where the "cat killing" values are.

The plan is to get a supercat or something in spring, not sure if I can go the midpipe route as I don't want the attention, the shiny blue car is enough :P

 

CAT-killing is kinda hard to predict.
There are two scenarios where the CAT gets baked: lean cruise and lean WOT.
The lean cruise situation is probably the more damaging since it is sustained, but how lean is lean?
I'd say that if your cruise values stay between 13.9 and 14.7 or so you should only experience minimally shortened CAT life.
If your sustained cruise AFRs are touching 15 or staying even higher, let me know and I'll "fatten up" your cruise values on your final tune.
Those without a CAT will want to cruise at 15 or above up to the point where they experience surging.
Different cars react differently to lean cruise values, so feedback is necessary to tune lean cruise.
My car will cruise just fine all the way to nearly 17:1! Another car here in Phoenix was not happy beyond 15:1. I think Flashwing's car started getting finicky around 15.7:1.

 

Cool. I'll look at the values when I'm logging. I can write if I want the cruise "fattened up" in the additional info section if you read those every time?

 

my 6 months went by and i never took advantage of the tuning calibrations because i think that all that tuning stuff is beyond me.



i still think so. maybe in time i can teach myself. it would help if the accessport software would install on my computer. i have vista 64 bit.

 

so what was the point of getting the AP if you didn't have MM make you any calibrations?
