Dadoulis Paschalis Posted July 19, 2013 Report Share Posted July 19, 2013 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! Quote Link to comment Share on other sites More sharing options...
Simon Posted July 22, 2013 Report Share Posted July 22, 2013 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. Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted July 23, 2013 Author Report Share Posted July 23, 2013 I thought so too but I ll give it a try and let you know the results! Thanks Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted July 31, 2013 Author Report Share Posted July 31, 2013 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 Quote Link to comment Share on other sites More sharing options...
Simon Posted July 31, 2013 Report Share Posted July 31, 2013 I would try the 2NZFE trigger mode. Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted August 1, 2013 Author Report Share Posted August 1, 2013 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 Quote Link to comment Share on other sites More sharing options...
Simon Posted August 1, 2013 Report Share Posted August 1, 2013 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 Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted August 1, 2013 Author Report Share Posted August 1, 2013 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! Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted August 2, 2013 Author Report Share Posted August 2, 2013 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 Posted August 5, 2013 Report Share Posted August 5, 2013 The vvt will not stop the engine starting. You can normally configure triggers and get engine running before sorting out VVT control. Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted August 5, 2013 Author Report Share Posted August 5, 2013 Yes but why as soon as I choose one of the sync modes engine goes off and then I cannot start it? Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted August 5, 2013 Author Report Share Posted August 5, 2013 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 Posted August 5, 2013 Report Share Posted August 5, 2013 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. Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted August 5, 2013 Author Report Share Posted August 5, 2013 So the only way is to find somehow exactly the pattern of the 2nd trigger, how can I start on this?? Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted August 5, 2013 Author Report Share Posted August 5, 2013 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! Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted August 6, 2013 Author Report Share Posted August 6, 2013 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   Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted September 5, 2013 Author Report Share Posted September 5, 2013 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! Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted September 6, 2013 Author Report Share Posted September 6, 2013 So nobody can help on this? Anyone with a vvti setup?? Quote Link to comment Share on other sites More sharing options...
Simon Posted September 9, 2013 Report Share Posted September 9, 2013 Can you confirm the trigger pattern on the cam signals, Are there 3 teeth at 90deg apart Quote Link to comment Share on other sites More sharing options...
Simon Posted September 11, 2013 Report Share Posted September 11, 2013 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. Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted September 11, 2013 Author Report Share Posted September 11, 2013 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 Quote Link to comment Share on other sites More sharing options...
Simon Posted September 12, 2013 Report Share Posted September 12, 2013 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. Quote Link to comment Share on other sites More sharing options...
Simon Posted September 13, 2013 Report Share Posted September 13, 2013 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. Quote Link to comment Share on other sites More sharing options...
Dadoulis Paschalis Posted September 19, 2013 Author Report Share Posted September 19, 2013 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! Quote Link to comment Share on other sites More sharing options...
Simon Posted September 19, 2013 Report Share Posted September 19, 2013 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.
