Hey guys, just got my 3sge beams engine running in my corolla with the Link g4+ monsoon and a harness built by Panic Wire. I'm having some issues with my Link Can-Lambda unit though. There was originally an OBD plug with the power, ground, can H, & can L wires I needed for the 02 in the Panic ECU harness. So I cut the plug out and soldered a new extension to the 4-way deutsch lambda plug. I originally had the wires mixed up due to the wire colors being different than the link pin diagram. Panic uses the universal can-obd wire colors. It is now wired with 12v to the power and 2.4v for both can H & can L. He also said it should be fine that I connect straight to those 4 wires and do not need a relay or capacitor. Now the issue, in the "runtime values" the CAN tab shows all green/ok but in the ECU STATUS the lambda 1 error displays 26 battery under voltage, then 33 open circut APE-IPE, and 16 heated too long. The status goes back and forth from diagnostic to calibration and the temperature back and forth from 32f to 750f or so. AFR always reads 10.08. Voltage is around 13.5v. I also setup the can setting to the link ecu specifications on the site. I will attach a log file showing the info and could use some help with this. Should I wire it differently, was the unit damaged by having the pins mixed up at first, or are there some settings I should change? Any insight would be most appreciated and thanks for reading. lambda error.llg beams.pclr
TL;DR: Add a 22uF capacitor to your CAN-Lambda, as close as humanly possible to the device. Nasty problem with my CAN-Lambda. On startup, watching the runtime values "ECU Status" tab, Lambda 1 box: Before startup, it's OK/diagnostic/waiting for rpm. After startup it cycles. Calibration Heating Error After heating code 33 Open circuit APE-IPE code 16 Heated too long While heating, the temperature very rapidly rises to 500-600c (2-4 seconds depending on exhaust gas temperature) before the code 16. What I've tried: Carefully inspected wiring harness on o2 sensors. No issues. Carefully inspected wiring harness on CAN-Lambda. No visible issues, but I couldn't disassemble the pins to verify the crimps on APE and IPE wires (lack special tool or understanding of connector). Replaced o2 sensor with a brand new one from Amazon. Exactly the same behavior. Allowed the engine to reach operating temperature with mixed low and high idle. Verified 0 CAN 1 Receive Error Counter. Verified 0 CAN 1 Transmit Error Counter. Verified 0 ECU Fault Codes Verified operating battery voltage 14.2v Log file is attached. Observe parameters Lambda 1, Lambda 1 Error, Lambda 1 Status, Lambda 1 Temp to see the cycle. It's the same with both LSU 4.9 sensors I've tried. Pclr is attached for 4age 20v engine. It's a work in progress. Log 2017-02-16 9;36;52 pm.llg 4age 20v.pclr
