superstock may > *

tune for a 12.0 is basically the rule of thumb, if you have to go lower, DO NOT go higher.

 

[xDJ DUBx]

higher is lean right?

 

[Wagonbacker9]

correct. more air means higher Air to fuel ratio... which means: go boom.

 

[xDJ DUBx]

yeah, know that just making sure. I guess I'll compare the superstock to fmic map and go from there once I actually start.

i put in the one step colder plugs and the car is staying around 10-11afrs. I dont think thats right...

 

[neysha_eddie]

correct me if i'm wrong but stock is higher than 12.0 ?

 

[Wagonbacker9]

no, stock is around 10. pig rich as soon as you hit boost.

 

[BadBandar]

no, stock is around 10. pig rich as soon as you hit boost.

so around 10-11 wont blow the engine right? Ill see if i can tweek it a bit. I want to be around 11s.

 

[neysha_eddie]

well i install wideband yesterday and at idle it reads from 14.7 to 15.3 but what your saying while boosting it should be reading lower?

you're more than safe.

idle is a whole different ballgame. under boost is when the SSAFC is activated (on the superstock map its about 2psi that it activates, but its adjustable). I'm talking about under boost, which is when the tune really matters.

 

[neysha_eddie]

ok i think i get it a bit now so when while i have the supermap install and i am under boost i should see readings around that area so anything higher than 12.0 will cause me to go BOOM ? sorry ask so many question i'm new at this tuning thing also

 

[Wagonbacker9]

anything higher than 12 is considered unsafe. the superstock map should keep you in that area.

 

[neysha_eddie]

aight so as long as i am running supermap it try keep me at a safe level

Alright well I'm tired of waiting for my friend to help me tune this thing. I want to try and learn this myself, so what is the best way to get started? I have the stock super map loaded already.

-Do I need to have the datalogging wires attached to do it myself? Or is that just a nifty feature to have? I plan on installing them ASAP but I don't have a soldering gun.

-Does anybody know about how much the Air/Fuel mixture will change if I alter a cell value by .1? Just trying to get a feel for how sensitive the program is.

-Lastly, do I just start plugging away at areas in the powerband that appear to be super rich?

Thanks guys.

1 its optional, but needed if you're gonna mess with the tune.

2 its not absolute

3 sure, if you know what you're doing.

That's what I was expecting to hear. Time to search for a soldering gun.

final question i just need to know if im on the right path my mod are listed below. Just need to know if a good idea to run Supermap until i can get a good tune? Also does it come already with the afc or do i have to get it from here?

Mod list
Turbolifes FMIC & Boostsciences Rdv
Corksport 80mm exhaust
Injen CAI
Boost gauge & AEM wideband

 

[Ricktalife]

Anybody have an idea if this is the stock ECU map or what? I would like to try it out but I don't want to blow the engine if it is just some trial tune that is for a completely different car. I have no idea how I got it lol.

That's what I've been doing but it doesn't seem to be working all too well so I'm looking for more ideas.
