Tricking the ECU to Relearn AF map - Page 2 - Toyota Yaris Forums

I don't like the cold idle at all. I keep feeling that I may be stressing the internals more than before...

PHXDEMON · 04-11-2009, 06:39 PM

How high is the cold idle? Like 3k RPM?

Yoda · 04-11-2009, 07:04 PM

i can take that tb off your hands rigth now barber it is the right one for the yaris? fits the 08 SD?

gwasabi · 04-11-2009, 07:36 PM

my cold idle is 2k

*tk-421* · 04-11-2009, 09:57 PM

My cold idle is almost exactly @ 2.5K

couple of questions....where did you guys get these tb's? Junkyard ? how much did they cost you? Can you feel a noticeable power increase? Has your MPG suffered? And the last and most n00b question...how many do you need anyway?

gwasabi · 04-13-2009, 03:31 PM

In hawaii, You can get these at junkyard for Cheeeeeeeeep! 20 bucks for some high scaled junkyard, FREE.99 for some whatever kind junkyard as long as you get big pocket. I bought mine from barber though....you never know what happened to the TB in the junkyard might be all buss up.

BIG NOTICABLE POWER INCREASE! Midrange to Higher RPM. I used to have trouble getting to 60 in stock after TB it goes 90 easy. MPG goes down but not by much. I noticed around 3 or 4 mpg. and you only need one TB

Hit up barber I think he has a extra one

MGargano · 04-13-2009, 07:13 PM

Just installed my 1ZZ TB and got a CL instantly on first start-up to clear the bubbles from the radiator hose (Step 2). I have the car sitting now with the battery disconnected... will try steps 4-6 in a few hours. Hopefully this works since I more than a little nervous about trying the chip swap!

at3GG · 04-13-2009, 07:37 PM

how hard is this to swap?? anything required besides the TB itself?

at3GG · 04-13-2009, 07:38 PM

and barber how much for the TB you have?

gwasabi · 04-13-2009, 07:38 PM

No not hard at all just gasket i guess

at3GG · 04-13-2009, 07:40 PM

gasket? as in modifying the stock one or purchasing/ making a new one? Pretty n00b at this as you can see. Any one interested in doing a DYI lol

gwasabi · 04-13-2009, 07:41 PM

Gasket maker. That's what most people are using. I didn't use any gasket though.....mine didn't come with one stock so I figure just put em in hahaha

at3GG · 04-13-2009, 07:48 PM

haha nice...anyone got any pics of install or before/after etc?

MGargano · 04-13-2009, 11:59 PM

I just went out to perform steps 4-6. The engine oscillated for about two minutes and gave me the high cold idle, but the CL is gone without doing steps 4-6. I'm hoping the oscillation goes away and the CL stays off. I guess time will tell.

gwasabi · 04-14-2009, 12:01 AM

Oscillation should be gone too try doing the steps one more time usually it should only takes the ECU 15min to learn the drive style but it might be a little dumb so go try it one more time oscillation should go away

MGargano · 04-14-2009, 12:11 AM

I actually didn't do the steps since the CEL didn't come back on. I figured the oscillation would just go away on its own after driving the car normally for a while? Or should I do the steps anyway?

gwasabi · 04-14-2009, 01:45 AM

you should do the step or oscillation will come back until you do it because the ecu gets confused. if you dont do the last steps the oscillation will come back randomly while your driving.
