I know there were posts back a while ago that talked about what the stock trd s/c air fuel tune was but I can't find the post. can someone tell me what they are at idle and partial throttle ...and wot at redline?

thanks

 

hope this helps, on the first dyno the blue is stock.

 

lol sorry, https://www.scionlife.com/forums/viewtopic.php?t=184169

 

ah - thanks - what i wanna know is how bad it is for the car to idle real lean .... as soon as i tap the gas it gets better. At redline im at around 11 but it cruises around 15 .... i just added a bottle of octane booster for the next 2 tanks of gas till i get tuned next weekend.

 

you should be ok

 

yea I put my stock airbox back on and i noticed when idle the car does run lean as all hell. I even reset the ecu .... and let it run for 15min ....then drove it on a few days ....same. So i guess its normal.

 

The car is suppose to idle at 15. if theres no load on the car, your fine. I usually keep my idle around 16, and on the highway around 16. Saves alot of gas, and cleans my plugs a little from the car running rich in boost. 11's is perfect for WOT boost. any higher than 12's is to lean for WOT.

The car factory runs 14.7 - 15.2

Your just paranoid because your actually seeing the numbers there, lol. Its fine, enjoy your car.

 

^ that is 100% the case ...now that I see the numbers im "oh my god ... i know these arent the numbers that ill see after my tune"

it was bugging me out

 

its just hard to believe the car runs around 17.7-18.2 at idle ... i was thinking higher 17's - At WOT its 11something close to redline then high 10's at redline

 

Sounds like you have a pretty decent tune, and a very SAFE tune. I would maybe add a little fuel to the idle, and that it.

 

no no - i dont have my tune yet. i just had my gauges installed and now im going for my tune in a week or two. I was just shocked at how the tune is with the stock setup .... i reset my ecu twice thinking that things werent right.

 

No, what i mean is that it seems your current factory tune is very safe.

 

oh ok - In between shifts the AF should be dropping all the way?

I am new to the specifics of AF's so my questions are noob-like.

 

It pegs rich? like in the 10's when you shift? is that what your asking?

 

no - it pegs lean ...

 

could be from the bpv valve

 

not sure but my bpv is leaking 2lbs of boost .... i emailed the company .... i hope they refund me w/o the 15% restocking fee
