  1. Hey Adam, sorry for the late reply. The reported TP vs. TP volt difference is at around 29:52 mark but again, not sure how much to nitpick since the time stamp differences are in miliseconds. For the speed lockout, I did not change the lockout speed. It is the same whether I use driven on non-driven wheel speed. Perhaps I should try setting the non-driven wheel speed not as an average of both wheels but try to use a single wheel speed sensor? The voltage drop corresponds to me almost stalling, rpm was 297 at the point where the voltage dropped to 11.92 V. I did scrape the exhaust a few moments later and the lambdas did reset for some reason. But the lambda error 4 happens randomly after lambdas are powered on. This has happened on two different ecus on two different cars. Perhaps I am doing something fundamentally wrong with the wiring? Wire gauge, etc.? The error does not trigger the CEL. PS. I though the the lambda error for low voltage is 26.
  2. Map is attached to the original post. I can add a drive link if it's not working. I haven't touched the throttle body in any way. I'm using 2003 350z tb, they both have some free play but I assume it's normal. They both work on standard 350z's. Thanks, I will check the wiring first chance I get. I am not sure how much I can nitpick the log but in some instances the TP main voltage does not change while TP main % does. Any ideas on the other two issues?
  3. Hey, I am having a couple of issues with the tune and can't figure it out: First thing, I'm getting erratic TPS signal (DBW setup) at speeds from 2 to about 10-12 kph when the car is warmed up. Changes in TPS causes acceleration enrichment to kick in, which causes the car to jerk/surge. Trying to chase this down but feeling a bit stumped. TPS is rock solid in every other driving situation including idle. Could this be wiring, electrical noise, ecu? Changing the throttle body did not help. Secondly, idle speed control seems to be ignoring speed lockout in closed loop mode. Closed loop works to about 8 kph even though speed lockout is set to 2 kph. However, idle ignition control stops working at speeds above 2 kph. Can these to functions interfere with one another? Thirdly, unrelated but something I noticed and is worth mentioning. Randomly getting Lambda error 4, either on Lambda 1 or Lambda 2 but never on both and sometimes on neither. Also, this happens on two Thunder ecus on two different cars. Low speed log start at around 25:30 min file time Log: https://drive.google.com/open?id=1Smp37nyfwA_Vemwsli1j43NFW8skae7k G4+ Thunder 1uzfe v1.1483.pclr
