artfuldodger613 Posted October 10, 2016 Report Share Posted October 10, 2016 (edited) i have a 2jzgte vvti singled with link g4+ xtreme.when i reach 5800+rpm my reading sometimes jumps to 10,000+rpm for a split second.There are NO experienced tuners locally for LINK. Id like to figure this out before going back to a tuner.I notice that my (ign angler) drops significantly when my rpm reaches 6100rpm. I have other loggings where the rpm spikes to 10,000+rpmLog 2016-06-22 8;37;41 pm.llg Log 2016-06-22 8;46;55 pm.llg Edited October 10, 2016 by artfuldodger613 added new pcl view Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 10, 2016 Report Share Posted October 10, 2016 Can you attach your .pclr also? artfuldodger613 1 Quote Link to comment Share on other sites More sharing options...
Scott Posted October 10, 2016 Report Share Posted October 10, 2016 Yes, having the base-map would be helpful.One thing I noticed between your low speed and high speed trigger scope images is that on Trigger 1 the lower edge of the tooth after the gap seems to be moving up towards the zero volts line. If this trend continues then the ECU will not count the tooth.Scott. artfuldodger613 1 Quote Link to comment Share on other sites More sharing options...
artfuldodger613 Posted October 11, 2016 Author Report Share Posted October 11, 2016 Thanks for the quick replies guys...I have also added a run i just did today. I have installed a 350z 6speed trans into my lexus is300.The new file is with the new trans. Car runs a little worse now. I only had a base map created and 30mins on the dyno since installing the link. I KNOW it def needs work...I have not wired in my wideband as of yet... Can i feed the link with the o2 sensor that is oem for the 2jzgte vvti?I ask this because i still have this o2 in the piping from running the car on stock ecu... This would be easiest for me but i realize i will need to wire up the wideband eventually. Thanks a million guys Seans PCL File.pclr Log 2016-10-11 7;26;40 pm.llg Quote Link to comment Share on other sites More sharing options...
Scott Posted October 12, 2016 Report Share Posted October 12, 2016 Thanks for the base-map and log file. I can't see any problems with the engine speed or trigger inputs in this log file. I did notice in the Trig 2 Arming Threshold Table that the 4000 and 5000 rpm cells may need some attention. You should use the ECUs TriggerScope to determine what the peak positive voltage is, and then set the cells to half this value.The G4+ Xtreme Black ECU does not have an onboard wideband O2 controller, so if the factory O2 sensor is a wideband one you will not be able to wire it direct to the ECU. However, if the factory O2 sensor is a narrowband type sensor you can wire it direct to one of the ECUs An Volt channels. The narrowband sensors are of fairly limited use though.Scott Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 12, 2016 Report Share Posted October 12, 2016 I don't have much to add on top of what Scott has already said, but I did want to point out just in case you did not know - your main ignition table (also lambda target table to less extent) is pretty extreme above 180Kpa, you will likely break the engine if you leave it like that and run into those cells...

artfuldodger613 Posted November 11, 2016 Author Report Share Posted November 11, 2016 I am taking it to a tuner next Thursday. I have since worked out most of the bugs. I do however have a strange issue. When I rev the engine past 2500rpm under the hood I can hear my vvti solenoid TICKING quite loudly actually. You can feel it to the touch right through the vvti solenoid housing. I have it unplugged and the sound goes away. Is this the tune or is the sensor buggered? I'd love to know before I bring it to the tuners. It's the cost of a hotel 4.5 hour drive each way and a missed day of work... I don't want to waste my time with any issues...thanks in advance guys !!! Quote Link to comment Share on other sites More sharing options...
Scott Posted November 11, 2016 Report Share Posted November 11, 2016 The ECU is normally controlling the VVT solenoids. I recommend having at a look at the VVT tab of the runtime values window while the solenoid is ticking and see what the status says.Scott Quote Link to comment Share on other sites More sharing options...
