so what happens after 1 more day? don't know how its gonna work when i get it back if it might do the same thing (cause misfire).

 

If it does the same thing, it has got to be something with the way you installed it.

I will ship it back when I remove it. At least I am sure there is noting wrong with the box.

ROAD/RACE

 

ok yeah thats a good sign, but i know i got it installed right cause i even tried it without solder. just twisted the wires together to get a direct connection. well we'll see, hopefully it works this time.

 

Is it being sent back yet?

 

FIrst theing next week. I want to check one more parameter of the tune first.

ROAD/RACE

 

sounds good

 

when you said next week, did you mean "today" next week, or next next week, like on the 1st or 2nd (whenever next monday is)? Not being pushy or anything, just checking so i know.

 

Originally I meant this week but be patient. I want to fine tune a little more.

ROAD/RACE

 

yeah i am, i was just checking so I'd know when. take your time

 

Hey Rob, why the switch from the box with the vac line to the one without? I would think the bax with the vac line could respond the changes better than the one without? Just curious why you switched.

 

vacuum box is not as fast as electronic... only reason for that box was so that it could see boost pressures. That box will still be used on stage 2 applications but for NA it was proving less responsive.

 

Good point. So if the box is not using the vac signal, which signal is it using to interpret airflow? The signal from the MAS, O2?

If you want to see how crappy Mazdas software is from the factory check out the dyno runs in my sig. The shop finally got the dyno run files to us.

 

Boe to the rescue....... He wakes up earlier than me.

ROAD/RACE

 

It reads the MAS signal directly and manipulates that much like an AFC would... only difference is that there is more finite adjustements with the piggy than any AFC/SAFC.

Looking at that dyno you definately need and AFC/SAFC or some sort of piggy back to cut that fuel out in the mid range/boost onslaught area. It's off the charts rich... way to much.

 

Yeah, I exported the data and there are sections of sample data that are stuck at 10:1 A/F. If the curve was followed it would probably read as low as ~8.5:1 or something. My AFC is on the way, it should be here early next week. Dynos will probably take place mid-October, unless there is another dyno day.

Back on topic, are there any dyno runs on NA Lancers with the new piggy?
