mackaycustomz@gmail.com Posted August 18, 2022 Share Posted August 18, 2022 hey guys I'm having a issue with a Ba turbo iv been looking at it seems as it cuts out around the 195ks. the boost falls to 0. afr stays good. here is a log and a photo of the dyno run. normal light load seems to not be a problem but as soon as the run starts (70km) it goes into torque source - trans torque truncation iv tried disabling module switch for tests, disabled traction control, put in all different settings to remove the trans truncation function tried with abs- without abs, boost through ecu- disabled boost through ecu and just wastegate pressure! open to any suggestions or opinions if anyone has seen this before!! cheers jake desktop datalog.teclogba xr6 read trans trunk PM Log 2 .teclog as this one is really playing funny buggers Quote Link to comment Share on other sites More sharing options...
Stevenbruzz Posted August 23, 2022 Share Posted August 23, 2022 Have you tried adjusting the trans max tourqe, I had similar issue when i put a built box in and set the trans setting back to stock, i chased my tail for ages new coils plugs new actutator. But later worked out was in the tune. I had help from someone else and its now fixed 😁 Quote Link to comment Share on other sites More sharing options...
BeerTurbo Posted August 26, 2022 Share Posted August 26, 2022 those two logs dont have speed. do you get speed source to the PCM? 1 Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted September 12, 2022 Share Posted September 12, 2022 Reduce the boost and see if it goes away. Then you know if its a torque/overboost issue. The fact you are seeing transmission torque truncation as the torque source pretty much tells you the issue. Check for DTC codes using forscan as well, it could be another issue like bad VSS signal etc causing your grief. edit: Your OSS and VSS are both 0. Is this a conversion car? This is definitely your problem. Is it a manual or an auto? Get the speed source/OSS sorted and your problem will be resolved. Quote Link to comment Share on other sites More sharing options...
