Thank you for the advice. Especially where to connect the cam signals.

Installing a G4+ Xtreme on an Audi 4.2 V8 with all 4 VVT cams. I can not find any information on Audi V8 VVT mode that is available in the VVT menu in the PC link software. Can somebody confirm if this VVT mode supports all 4 cams with VVT. Cam trigger has 2 long and 2 short teeth as many other VW/AUDI cam triggers.

There is a around 10% difference between effective and actual PW. Since the car has a hard time starting I'm looking at cranking pw of around 10ms for 5 , 10 or even more seconds. Then after the engine starts if will fall down to 5 , 4, 3 ms as is goes through the post start tables. So I need to know what tables have some effect on this cranking pw that can go on for minutes (untill the battery has enough power) until the engine starts. It seems none of the before mentioned tables and changes to them have any meaningful effect on cranking pw. Any suggestion at what tables should I look would be appreciated.

Where does the G4X look for injector opening times in ms when cranking? No matter what I try to modify It always shows around 10ms when cranking. Master fuel is set at 12ms, it idles at 3ms at 14:1 , fuel table value at 0 and 500rpm is 27. I went from 5 to 20ms in Pre-crank prime table. In First crank prime, between 50% and 200% Crank enrichment table between 150% and 300% All at same temperature, engine warmed up around 70degree Celsius. After all possible combinations are tried it moves maybe to 9ms when cranking. Engine has some problems starting so I would like to fine tune the engine starting. No matter what I modify, cranking ms does not move more than 10%. Throttle is not touched when cranking (idle speed control takes care of that) if I give it some throttle it will go to 20ms or more when cranking (TPS based map) as the fuel map values go to 40 and 70 with full throttle . With the G4+ I could see cranking pulsewidths changing with cranking tables mods. bmw_e36test.pclx

Another computer that works is a Lenovo Thinkpad T560 Win 10. This is like 4 years old. New Lenovo Ideapad does not work. There must be something different on the motherboard USB circuit .

I tried an almost new Lenovo Ideapad and no luck with it. Only 5 sec of connection when the engine is running. Still using a HP Elite Book 850 G1, going without disconnect like with the G4+. Anyone tried a newer Thinkpad 400 or 500 series? Those are more robustly built. Similar to an Elite Book which is top of the line at HP.

On my old Lenovo T400 series I have 32 bit Win7 and the 6.19.65 version of the software installed fine. Maybe the problem is with Win XP?

The notebook I used is an Elite Book 850 G1. I corrected the information in my previous post.

Calibrate function did its magic and VVT works as it should , cam angle follows the VVT table. Thanks to everyone that helped with suggestions and to the great LINK support team.

I received the ferite noise protected USB cable from Link and it made no difference. Before wrapping the entire engine in tin foil I tried a few other notebook computers. The ultra reliable Lenovo T400 series simply did not want to hold the connection for more than a minute and anything over 2000rpm would cause immediate disconnect. An office type notebook computer was luckily on hand for a quick test. HP Elite Book 850 G1. Not a single disconnect no matter how hard I tried. I will get my hands on a newer Lenovo T500 series to test the connection for future use. There should be a post on the top of the G4X forum with a list of notebooks that work with G4X to make the life easy for all the G4X users.

Thank you for the advice. Will try this settings and report back.

Are there some exact instructions fot BMW Vanos, what is pressure solenoid and what is bleed solenoid, advance or retard? So the calibrate function does not go crazy? What do I enter under tooth count? from ther triggercope it seems there are 8 tooth on the DI2 input signal.

I have connected and tested the Vanos VVT outputs so the vanos solenoids work (click) when in test mode. I entered all possible data about the VVT, In G4+ an AUX output is defined as VVT advance or retard solenoid. How do I define VVT advance or retard solenoids in G4X? I entered the data for AUX3 and AUX4 which are connected to the Vanos solenoids. How the G4X knows which AUX is meant for VVT advance and which for VVT retard? I can not find the option to assign an AUX to work as an VVT output so the G4X knows which AUX to use as VVT. I need some help to solve this. Here is the latest calibration file, and triggerscope. All signals should be fine now. bmw10TriggerScopeLog.llgx m3_e36new.pclx

Will do as suggested. I'm new to G4X so I need some help to set the VVT.

OK, will correct the wiring for the trigger 2. I'm asking about the VVT signal on DI2, what should I enter for VVT input, so the VANOS mechanism works? There seem to be a number of tooth on the DI2 signal. Before on G4+ there was speficic S50 trigger decoder for this type of VVT input signal. Will be in contact with the tech support for the ferite bead USB cable. Thank you.
