Carfreek Posted April 23, 2019 Report Share Posted April 23, 2019 I have concerns that I may have triggers with reversed polarity on my toyota 1gzfe build. I did not have cars pinout, made educated guesses concerning wiring of triggers, engine has 2 crank sensors and 2 cam sensors. . Car is started and runs, but timing seems off. I ran a scope capture, its attatched here. Can you tell from this if polarity is wrong? Thanks in advance Trigger Scope Log 2019-04-23 2;10;54 pm.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 24, 2019 Report Share Posted April 24, 2019 Polarity is correct and the waveform looks good. I assume you are using 1JZ vvti triggermode? Have you done the trigger calibration/base timing? Quote Link to comment Share on other sites More sharing options...
Carfreek Posted April 24, 2019 Author Report Share Posted April 24, 2019 (edited) Thanks for the quick reply. I am using the 1jz settings. While I had it running, I was trying to set the base calibration, but the ecu will not unlock the offset value. I cant find any instructions on how to unlock these fields. I have tried clicking on the lock button, and right clicking on the offset, but it will not change the value. Storm rev 1.7.

Adamw Posted April 24, 2019 Report Share Posted April 24, 2019 Just double click the spanner beside set base timing, that will open a new window. In there is where you adjust your offset. A common gotcha is if you are manually typing in a new offset you need to hit the enter key to make it take effect. The number will turn blue to indicate it has taken effect. I normally just use the pg up/pg down keys to adjust so I can do it with one hand on the timing light - you dont need to hit enter in this case.

Carfreek Posted April 24, 2019 Author Report Share Posted April 24, 2019 Thats exactly what I needed. I wasnt hitting enter. You guys rock! Quote Link to comment Share on other sites More sharing options...
Carfreek Posted April 25, 2019 Author Report Share Posted April 25, 2019 Had to put in 40 degrees of advance , 245 offset now. Seems like an odd number. Still getting a random backfire...wondering if I need to go 360 down and input -115 as the offset? The help section mentioned this as an alternate..

Adamw Posted April 25, 2019 Report Share Posted April 25, 2019 If you are saying it doesn’t run at all and only backfires, then yes it is likely 360 out. However if you are saying it actually runs but backfires sometimes then you have some other problem. Quote Link to comment Share on other sites More sharing options...
Carfreek Posted April 25, 2019 Author Report Share Posted April 25, 2019 It actually runs fairly well, and backfires sporadically. Burnt up the o2 sensor, with raw fuel on startup settings so its waiting for new parts. Ive seen other people with 1 gz builds mention it was within 5 degrees or less. Thank you again.

Carfreek Posted September 13, 2019 Author Report Share Posted September 13, 2019 Engine is now running great, earlier issues were wiring related. I am running with vvti wired up, but not enabled. I am wondering if anyone else has set up vvti on one of these, and which settings to use. Thank you.. Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 14, 2019 Report Share Posted September 14, 2019 If you attach your tune and list which I/O your solenoids and 2nd cam sensor is connected to I will set up the basics. Quote Link to comment Share on other sites More sharing options...

Aux 4 vvti pass side That doesnt mean anything to me without knowing what side of the road you drive on. It may be clearer to use Lefthand/Righthand. 2 hours ago, Carfreek said: I may have my tuner contact you direct as he will have the car monday the 23rd..next time I will be able to download file at shop will be sunday...thank you. Note I dont work for Link, and its not Links job to set up your ECU. Happy to help here on the forum in my own time when I have time however.

Carfreek Posted September 22, 2019 Author Report Share Posted September 22, 2019 Sorry, if I misunderstood, or wasn't clear. Left hand drive. I understand it's not links job. I was looking for someone who had done the 1gz vvti settings. Frankly my first time setting up vvti, wanted to be sure I was on right path. Thank you.
