I had a slightly technical question for you guys, if you could answer it, that would be great!
Whenever I am logging my car during WOT 3rd gear pulls – the logger laptop software drops out. If using an SD card straight into the Tactrix OBDII port – impossible values are recorded in that area for a few seconds.
This happens only on WOT, at around 5000rpm in 3rd gear. 1st and 2nd gear aren’t plagued by this issue.
My initial thoughts were electrical interference – so the engine grounding wires were inspected, brand new car battery, new battery grounding terminals, cables etc. Ferrite chokes on the OBDII wires – nothing has helped.
I’ve tried logging fewer parameters – so far it manages to hold only one parameter without dropping out. This is really useless as other same model ECU/cars seem to have no problem holding 17+, and mine holds 20+ very well as long as I keep the throttle under 90% in 3rd at high rpm.
Different Tactrix OP 2.0 have been used, different laptops and software like EcuEdit have also been used. Same issue.
The rpm needle also hesitates for a second around 5000 when on WOT - someone said it could be related to coil packs/connection.
Please help!!! (if possible
Cheers,
