Piggysniffer Posted October 5, 2016 Share Posted October 5, 2016 Well mine pulled a load of timing yesterday at low revs and dropped my IAM down to zero, so I have still got issues with it, even more weird is the fact that the IAM is zero but the car isn't in limp mode, it's still boosting 19psi, supposed to go into limp mode at anything under .25 on the IAM ive gotten to the point where I just have to laugh about it lol Quote Link to comment Share on other sites More sharing options...
Jay762 Posted October 5, 2016 Share Posted October 5, 2016 Hi sorry - slightly confused by the TLA - are you saying your Intake Absolute Manifold Pressure is down to zero? If the car is still generating boost but the manifold pressure is zero there is a huge mismatch (or hole) somewhere between what the turbo is capable of holding and the engine needs. The MAP sensor is a key player here but given the history I wouldn't know if it was calibrated prior to or during the session you had. We just have a snapshot of one thing happening and no view of the relationship to the rest of you motor so I just guessing - sorry Quote Link to comment Share on other sites More sharing options...
Piggysniffer Posted October 5, 2016 Author Share Posted October 5, 2016 IAM = ignition advance multiplier, or DAM in earlier models, it's a rough timing correction 🙂 The limp mode is where the ecu limits boost to 7psi waste gate pressure and runs a richer fuel map and the car is supposed to be in limp with an IAM of 0 Quote Link to comment Share on other sites More sharing options...
Piggysniffer Posted October 5, 2016 Author Share Posted October 5, 2016 Got in it this mornin, IAM straight back up to 1 lol i did chuck a 750ml bottle of slick 50 in it last night tho Quote Link to comment Share on other sites More sharing options...

Piggysniffer Posted October 5, 2016 Author Share Posted October 5, 2016 I rate it, put it in both my Sierra cosworth engines after I'd run them in and I used to really thrash the living death out of them both, a lot of people say it's snake oil, all I can say is, it never did any harm Quote Link to comment Share on other sites More sharing options...
