Summary of change:
||MembersPage/Sascha|| === JP Diaz VR6 Drag Golf === ---- === Basic Info: === * **Current configuration** **Primary Trigger: VR + OEM 60-2 Wheel **Cam sync: NO **Injectors: 6x ID2000 **Ignition: 3x GM Wastespark coil packs **TPS: Mustang **CLT: OEM/Bosch **IAT: OEM/Boscvh **IAC: None **Knock: No **SD Card: Yes Current FW: 1.2.11 '''Issues with lambda getting "stuck" at 0.83''' Issue with lambda getting stuck when doing a power pull, issue started out of no where and consistently getting worse so the point that I can no longer read lambda under large loads. Wiring has been checked, and re-checked... Sensor is new. Sensor had a hard time to calibrate at the beginning (seemed like heater wasn't activating correctly all the time under calibration) I had to start/stop the calibration process a few times in order to get the O2 heater activated for free air cal. Seemed to read fine otherwise and is accurate under light loads @ idle. Screen shot of log: https://lh3.googleusercontent.com/-PXarbxmwzf0/U-ETDvLJ1lI/AAAAAAAAX5E/kiRoSY0Sm58/w1317-h681-no/jp-log-lambda-stuck.jpg Lambda sensor eventually recovers in approx 2-3 seconds of overrun: https://lh4.googleusercontent.com/-PIzTVd8e_Zw/U-EWczHTrbI/AAAAAAAAX5U/m_ilyylYQ50/w869-h767-no/jp-log-lambda-stuck-recovers.jpg ---- === Adding 2nd wheel speed input: === Just looking for some verification on this topic before I make some modifications... Can someone tell me if what I've drawn up here will be ok? I've made this sketch according to the information I've got from speaking with Marcell. Just want someone to verify/back it up. *Instructions from Marcell: **wheelspeed2 is the (non-GND) SCL pin right next to SDA pin (third trig), SDA seen on bottom of : http://vems.hu/vt/help/v3/v3_camshaft_angle_control.html (yes, SCL pin is marked correctly on the pic) **4k7 or 10k resistor, and diode protection to 5V recommended (normal diode like 1n4007 in rescuekit: stripe-marked cathode on +5V, diode anode on SCL). Important (5V arrow points to wheelspeed1=PS2/clk on pic, see InputTrigger/WheelSpeed ): the '''+5V pad is actually at the bottom of the 4 pads''' (coming from the dedicated 78L05 supply regulator pic/bottom/right corner, in SOT89 package which looks like a spaceship from space invaders). **(alternatively: 5V1 zener to GND, in that case zener stripe-marked cathode is on SCL input; zener anode on GND) This is what I think it should be with the above instructions: https://lh5.googleusercontent.com/-kPvrBtzPk5s/VdYTYko8sLI/AAAAAAAAiD8/vbLFH9GUqnU/w414-h358-no/scl.png
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
