Hi all...

My car is pinging a bit under load and it's not to do with fuel becaused I'm using the 98 RON fuel... It doesn't matter how much I retard of advance the timing, it still pings...

If a knock sensor has come off, can this caus the engine to ping???

In that thread mate, what do you mean by "drive pulley keyway"? You mentioned that is was loose? Are you talking about the bolt that goes through to hold the pulley on?

This pinging only seemed to happen after replacing the exhuast cam and the Crank Angle Sensor... Maybe the CAS is faulty yeah????

On mine it was the pulley at the bottom of the motor that drives the timing belt and the half moon key had worn a bit so the pulley was rotating on the shaft, only very slightly but enough to put the whole system out.

Didnt you just have a problem relating to the CAS? I'd try another.

      I mean yes, if you're starting from scratch on an unknown engine yes you don't need to be doing all kinds of math in the background but if you're doing relatively minor changes like AFM + injectors + boost up with some aftermarket turbos it takes quite a bit of math if you want to do something like maintain OEM fuel + timing tables but compressed and then a bit more load scale up top. I think I've spent too much time working on big engineering nightmares though so I'm a big fan of trying to constrain the scope of whatever work I'm doing as much as possible and trying to get it right before moving on. For example, a local owner just did the usual E85 + single turbo conversion to his R32 GTR and nearly burned his car to the ground doing some spirited driving up the local mountains. Turbine is unshielded and too close to the hood insulation. It's tough to balance "just get the project done" and "seemingly small details can cause massive setbacks I'm not willing to deal with".

      No idea about Neil's steering wheel, but I have the same behaviour in the Stagea. I doubt it has ever been messed with so might be normal. Indicating to turn right at a roundabout and correcting even a little bit to the left to go around will cancel the indicator. Never considered it an issue other than it being a bit odd.

      Does anyone know if this is off centered? Looks like it, when I indicate to go right, but turn my steering wheel slightly left it cancels (was always like that even before I started messing around with it) was wondering if anyone else has the same issue?

      Nothing photo worthy since last update, lots of little plumbing bits for the AAC/Cold start valves, and unfortunately I still need another couple of parts for the brake booster line and the AAC into the plenum. Otherwise it all looks good to start up engine wise, onto checking the electrics/interior
