DesFlurane Member 351 Member For: 19y 1m 28d Gender: Male Posted 13/12/09 03:29 AM Share Posted 13/12/09 03:29 AM After my rebuild I went back to the drags today.Only had one run as could hear detonation.Definately seems to overboost on the changes (ZF auto).Also, something I've noticed when giving it hard acceleration it seems to cut boost. Thought it might be the auto getting confused or something but I now have the data log picture.Not sure about uploading excell file and what not but will graph and put in wordpad.

DesFlurane Member 351 Member For: 19y 1m 28d Gender: Male Posted 15/12/09 02:05 AM Author Share Posted 15/12/09 02:05 AM (edited) Doesn't appear to be flaring.Didn't manually shift as it was first time after the rebuild and wanted to eliminate one thing from the equation. Octane boost 'cos I melted a couple of pistons last time and a little extra insurance won't do any harm!

Go for a street run and add load and the turbocharger PIDS, duty cyle etc. Top end of the graph shows poor control over boost....
