Questions that need answering MAF Bosch signal characterization What voltage indicates "zero" flow? What voltage indicates negative flow? Does the ECU use it? Is MAP used in characteristic curve when ECU detects broken/unplugged MAF? Lemmiwinks High EGT and IAT corrections.. is there a flag for each, or is the correction progressive? does it affect both fueling and timing? does it affect req boost? does it affect load calculations? Generations There is some confusion with cars near the 09/00 build mark Some are 2001, some are 2001.5 (no verification of this rumor) Some 2001.5 came with h-boxes and do not appear to have F-hoses (doubtful, probably incorrect report)

Articles that need content Open loop/closed loop What determines which is used when? O2 sensor Knock control Relationship between KVs and timing correction factor Direct? Filtered/corrected somehow? Are logged KV's corrected? Characteristic curve When is it consulted? During both open/closed loop? Is MAP used? What if ECU detects broken/unplugged MAP? Manifold air pressure Synchronous path/Asyncronous path F-hose Why does it exist? Delete howto Master boost controller Parallel vs series vs alone Tuning Relation to throttle cut and TCD Throttle cut defender aka MAP clamp
