XAJG66 Posted May 25 Share Posted May 25 Hi All. I've just recently joined the pcmtec world, and this is my first time at tuning anything turbo. Anyway I've just started taking a few data logs and I've noticed that my BA XR6T, which is completely stock, with a stock tune and running Shell 98 is pulling as much as 7 degrees at WOT (from low revs, about 3 degrees if going to WOT from say 3000rpm). This surprised me as I assumed running 98 on a factory tune would leave a fair bit of timing in reserve, so I just wanted to check - is this normal or do I need to check out potential mechanical issues before I move on?

Puffwagon Posted May 26 Share Posted May 26 While this may not be your issue, this is a common effect from having a knock sensor unplugged or having broken wiring. If this is the case you will see in the log that the knock retard will go straight to a value and hold it there, the chart for the knock level will have a straight line. Normal knock activity moves around a lot and the chart will reflect that. This is something to check. Quote Link to comment Share on other sites More sharing options...
