I just installed the Simota CAI the other week. Just follow the same steps as the TRD one. It's exactly the same. Just remeber to reset the ECU. I found that resetting the ECU should be done when the engine is cold. So when u let the car idle it starts from cold to warm and therefore will adjust accordingly. I had a few problems with hestitation when accelerating but when I resetted the ECU when engine was cold it was all good.

Good luck mate

1) disconnet the battery for 30mins+

2) reconnect the battery and let the car idle for 5-10mins (make sure all the acessories are OFF)

3) turn the car off and disconnect the battery for ~30sec

4) reconnect the battery, start the car and drive the rings off it.

the last part of step 4 is the MOST important, um if you change the pod filter you should reset the ECU appart from nothing comes to mind

Can anyone explain the suggested and seemingly arcane ECU resetting procedure?

I have changed several times from the stock airbox to my CAI - WITHOUT disconnecting the battery and thus the ECU has not been reset. The ECU is always learning, so all resetting will do is maybe speed up the process of adapting to increased airflow (and therefore increase fuel delivery) with a CAI installed. But leaving it alone will eventually do the same thing...

As for disconnecting for 30 mins, then idling until warm, then disconnecting again for 30-60 seconds, then driving the tits off your car - that just sounds silly. The second disconnection will just reset the ECU again so why bother?

Why not just use Voodoo - it seems to have just as much validity and basis in reality as the above crazy procedure.

i've heard of others a step 1.5 should be included (press the brakes for a few seconds) apparently leaks out any energy stored the the cars electricals... where did you get the simotoa CAI how much was it???

I just took the rolla for a spin after installing the cai and resetiing the ecu and could not believe the difference :D its like driving a different car. One question though did any one else get a knocking sound when starting the car with the cai? on mine seems to do it every time, i think it could be the cai drawing in air on ignition? anyone else have any other theories as what it could be?

yes it does speed up the recalibration process, the 30mins is to clear the ECU so that it rememebers nothing, the 30sec is to let it reboot so to speak, its like updating system files on a PC it needs to reboot to use them the ECU works in the same way, and as for driving the "tit's" of your car, your ECU will learn how you drive and the first 2-300km is its steepest learning curve so you have to shape it so to speak so that you get the end result that you are looking for.

      1zz-fe engine rebuild

      Hello all, Working on my 2002 corolla. It needs a engine rebuild due to burning oil out the back. It has over 400,000 km on it and I havent looked after it. Everything is still original on the motor. The only thing that I have replaced, was the brushes on the alternator. They were completely worn out. I am pulling the motor/gearbox out of the car. Wont know the condition of the block or head until I strip it down. I know the design of the piston where changed in the 2003+ models for more oil holes, which stopped the buring of oil. 1. Was there any other changes made ? 2. Does anyone know of where I can get a engine rebuild kit for 1zz-fe motor in australia ? 3. I have only found one place that I can get a new short motor built but that is in the USA and they do ship to australia but was hoping to find something in australia Thanks for help. Dragon

      2007 Corolla Sedan rear seatbelt question

      Hi everyone, new member here. I've got a small problem which I'm hoping you can help me sort out. I've read the "read me first" thread and done a forum search so apologies if this ends up being a repost. Ok, so I've just has a bloody mouse chew through the rear seat and half (but only half) of every rear seatbelt. Which is nice. So I need to replace them. The problem I appear to have is that none of the local breakers have any suitable vehicles that I can pull them from and the ones I ordered and was sent from the bay of fleas has the wrong brackets on, despite being allegedly for that vehicle. Further searches come up with every seller showing the wrong bracket, so either I've got a special car which is different just because, or (more likely) they don't know their ****s from their elbows what they're selling. I'm after some aftermarket ones as they never get used and just need to be there to get through rego so don't really want to spend a heap of cash I don't have on genuine parts if I can avoid it. I've replaced the centre one (a mate just randomly had it in a box in his shed, which was handy) but still need the left and right. I've attached the bracket type I pulled from the car and need. Is this a standard generic Toyota seatbelt or specific to the 2007 Corolla sedan? Does is need to be specifically for the rear left and right or do front ones fit? Does anyone know where I can source an aftermarket pair? I will really, really appreciate any help offered with this, I know my way around a box of tools but very little about mechanikicing (which is part of the reason why I bought this car - something simple to learn on as repairs/replacements become due) and this is a simple fix which is turning into a drawn out headache. Thanks - Matt

      Hi from Wagga

      Hi folks, I'm in Wagga, have what I thought was a nice, cheap and reliable 2007 Corolla, and am joining in the hope of picking the collective brain to troubleshoot and avoid tossing my computer and the relevant car parts out of the nearest window. I'll play nice and restrict the swearing to off line areas :D See you on the threads! Cheers Matt

      Amplifier 88650-60D60 no longer made

      Hi all, Wondering if anyone has had this issue. I recently purchased a 2007 200 series landcruiser, and the amplifier for the air con unit stopped working. Part number 88650-60D60. (Looks like a circuit board) All controls for the air con now do not work, very frustrating in winter when you dont have any way to unfog your windscreen. Toyota have informed me that they no longer produce this part, and there is nothing superseeded to fit in it's place. My question is has anyone had this problem? If so what did you do to fix it? I have got onto an auto sparky who has had a go at fixing the circuit board but its unserviceable. Any feedback would be much appreciated.

      Engine oil dipstick reading

      Hi guys, Probably a silly question... I'm having trouble reading my engine oil dipstick on my Toyota Hilux 2010 3.0 Turbo Diesel. I have warmed up the engine, turned off for ~10 minutes, parked on a level surface. Pulled out the dipstick, wipe it and insert it back to the bottom and carefully lift it up. I tried so many times and the two sides always look different. I couldn't read it. Maybe I just don't understand how to read it. Could someone help? Thanks a lot!!!
