RAV4 2004 model 1AZ engine 2.0lt

[Dadoulis Paschalis]

Hi all!

Has anyone ever wired-in a g4 storm on a rav4? This model is a canbus model, so what's the general plan? Leave the stock ecu together with the g4 and process the fuel/ignition through the g4 only?

Thanks!

[Simon]

You might be able to do it as a piggyback but there is always a risk the factory might not like having things played with.

[Dadoulis Paschalis]

I thought so too but I ll give it a try and let you know the results!

Thanks

[Dadoulis Paschalis]

Hi again

Just wired up, of course it gets awful readings on rpm...so does anyone know whats the trigger setup on this engine for a start?

Thanks

[Simon]

I would try the 2NZFE trigger mode.

[Dadoulis Paschalis]

And things are like this...

I ve tried all ready options for toyota vvti but none worked...now after lots of trials 36 missing 2 option worked and engine starts ok..trigger error is 1-5 and as soon as it starts it goes to 0...BUT as soon as I select the 2nd trigger as any sync mode trig2:vvti inlet /lh engine goes off and I cant start it again even if I revert the changes...also 2 out of five times it disconnects me and doesnt even connect me to the ecu again until I switch off ignition and on again!!

Any advice for vvti settings?

Thanks a lot

[Simon]

Best bet is going to be to check the pattern for triggers on the engine.

Can you get a two channel scope image of a full engine cycle showing Crank trigger and Can on the same screen.

Or manually degree out the engine so you can send a diagram like what I have attached for the 2NZFE

[Dadoulis Paschalis]

This difference of time zones is killing me Now it s after midnight here!

I ll try to do that and let you know tomorrow!

Thanks for the help and continuous support!

[Dadoulis Paschalis]

Its the first time we use vvti on a G4 although we ve installed many g4 on starlet turbo or yaris but never played with vvti before so maybe there is something wrong with our wiring? 

Digital input for vvti and trigger 2 ?

[Simon]

The vvt will not stop the engine starting. You can normally configure triggers and get engine running before sorting out VVT control.

[Dadoulis Paschalis]

Yes but why as soon as I choose one of the sync modes engine goes off and then I cannot start it?

[Dadoulis Paschalis]

Exactly the same with the engine going off is happening if I have the trigger 2 wire completely disconnected so pclink doesnt show trigger2 signal with a yes...

[Simon]

When trigger two is not selected it ignores the trigger two input and only operates of the crank sensor. As this is multi tooth missing it is able to sync and run wasted spark and group fire fuel.

When you turn trigger two on or use a trigger mode that requires trigger two the signals are compaired and need to match exactly. If the tooth count or location is not as expect the engine will not run.

[Dadoulis Paschalis]

So the only way is to find somehow exactly the pattern of the 2nd trigger, how can I start on this??

[Dadoulis Paschalis]

Also the difficutly on the engine start-up 1 out of 2 times is because of this same reason? Reading of the position of the engine cannot be calcualted exactly and there are these misfires before starting the engine? Same moment if I turn switch on the ignition and then back on and crank it, it will start up just fine!

[Dadoulis Paschalis]

Sorry for repeating but I've read all help file refering to vvt control but reached nowhere

1) What can I use to get the two channel scope image as yours? Can I do it through the G4? Can I do it manually somehow? If so can you point me directions?

2) If I find this scope image you'll be able to tell me how the vvt control should be wired and set in pclink?

Thanks again

If I'm helping more, it goes 15-20 degrees and just this moment returns to 0, 15-20-0-15-20-0 something we can see in pclink running!

[Dadoulis Paschalis]

So nobody can help on this? Anyone with a vvti setup??

[Simon]

Can you confirm the trigger pattern on the cam signals, Are there 3 teeth at 90deg apart

[Simon]

Cam now only has one tooth as the other teeth have been removed? If so the VVT is no longer an option as we need all 3 teeth.

[Dadoulis Paschalis]

No problem to get the stock setup back with the 3 teeth, but my first question in this thread was what the trigger should be with these three teeth because none of the ready to be selected trigger patterns was working! What trigger should I choose from the list so as the three teeth to work?

Thanks

[Simon]

If you can get a scope capture when the engine is cranking showing both triggers I can look to see which toyota option will be the closest.

[Simon]

Attached is a example of what Im looking to determine.

I scope will give you this and also confirm the required arming voltage at crank.

[Dadoulis Paschalis]

Ok....I know that vvti needs three signals, so how can I set this in Pclink so as the vvti to work correctly?

I can't get a scope image!

[Simon]

Can you get the motor running in multi tooth missing mode and run the CAM test (info on how to do this is in the help file)

Pulse count will be 3 the figures from this will help.
