I’m going to try running a ground wire from battery negative directly to the block. Looking at my logs from before I did the relocation, logged battery voltage was very close to measured voltage at the battery.

tested w/ the dwell set to 2ms and it stopped breaking up at 5500. Now just need to fix my charging/voltage drop issues. thanks again

12.5v from the link software and 13.5v at the battery is a pretty big voltage drop no? I suppose I should also mention the battery was relocated to the trunk. I have the + 0 gauge wire running from the front of the car and the - grounded to bare metal/chassis in the trunk. Could this be part of the problem? Thanks

Thanks for the response. I recently tested the alt and it was ~13.4V at idle which seemed quite a bit on the low side. I will replace it and go from there. Besides that, would you suggest reducing the max dwell to 1.8-2.0ms? This is one parameter I haven’t adjusted at all from the base calibration.

Hi guys, Just recently put my daily back together and started the process of road tuning. Slowly getting the hang of things but I am struggling with diagnosing this issue. The car will rev to ~5500 rpm and hit what feels like a rev limiter. However, in the logs the RPM Limit is not activated. Also, the trigger error counter does not register any errors. This is a PanicMade AltezzaLink G4x running on a Lexus IS300 with the factory 2JZ-GE and all factory crank/cam sensors. Attached are my config and a log file in which I was able to reproduce the issue. Thanks! IS300ConfigFile.pclx 3rdgear limiter pull.llgx
