Tricking the ECU to Relearn AF map

I did. That gasket is a joke. I find it hard to believe that it does anything at all.

how to have more air to flow in to a N/A engine?
last time i drove a lancer the swap is easy as the TB is run by a cable but the new Yaris TB is drive by wire, understand to do a swap for TB is not that easy any more...

Is there any TB is direct swap in for Yaris engine?
Do we need to mod the TB plug to fit in the new TB?

Will the ECU have any issue to the new TB?

so my CEL came off today as i was driving into work

it kicked back on after about 110 miles of driving, im about 280 now and it kicked back off

this never happened during the first install, so trying it the 2nd way seems to be producing some kind of different result

i'll keep an eye on it and report back any findings

That's because you have air in your radiator hose. What I suggest is take the radiator cap off and run the car in idle until the bubbles don't come up. the fluid should overflow a little and then when it's settled just pop the cap back on.

[kustom play]

yea im going to give that a try next

thats the one thing i havent done yet

[gwasabi]

Also the Random Oscillation is due to the ECU trying to learn what to do with new TB. Did I mention that this method only works for manual cars? anyway, IF you drive around and get random oscillation just start driving a little harder for a while the opscillation should go away. If it doesn't turn the car off then on right away and it should go away. It happened to me for the first few days but after that it was gone. I have the TB on my car right now and I have NO PROBLEM what so ever with the new TB. No cel, No Oscillation. been like that for almost 5 months now

That ar in the radiator hose part is VERY VERY IMPORTANT! I think i should edit the first post lol

[kustom play]

it kicked back on again

im going to do it in a little bit and see if it help it at all

[kustom play]

burped the coolant

CEL has went off and it has not come back on again

so i hope this solves it once and for all

[Yoda]

i hope so too i am still waiting....

[kustom play]

my light went on again

so i give up trying to get it off, im just going to deal with it on

[gwasabi]

Just keep driving with the lights on eventually it'll go away

[kustom play]

just turned off again

so hopefully it stays off at this point

You are just getting a CEL correct not a CEL + oscillation?

[kustom play]

just the CEL

the oscillation was only about 5 mins after i hooked the battery up and it learned the new air map. I havent had an issue with oscillation since just the CEL coming off and on

[gwasabi]

Thats probably due to the Coolant just drive around for a bit and let the coolant settle. It'll eventually just go away

[kustom play]

i burped the coolant, and it went off then came back on now went back off, hasnt come back on yet.

hoping it just stays off, if not then ohh well, i'll just deal
