lekonna Posted July 13, 2012 Report Share Posted July 13, 2012 I'm having some troubles with the closed loop boost control. It looks like i'm missing the pre-spool stage most of the pulls i do. I have not been able to figure out exactly why it is missing in some cases, except a hunch that it does not fall back to stage 1 from stage 2/3 if it reaches it (due to for example lower boost request earlier in the table) i go wot while the boost control is active (2000rpm 80kpa) and it reaches my target of 0 boost and goes to stage 3. If somebody can confirm this i'll just fill out the whole rpm range regardless if the turbo can reach those or not. here are my pid settings: case where it just doodles around stage 2 without having stage 1 active at all. and case where the stage 1 is active, though i lost grip here so had to drop the throttle logfiles and map file http://zonediscgolf.fi/media/supra/logs_and_base.zip Quote Link to comment Share on other sites More sharing options...
ViPEC Engineering Posted July 16, 2012 Report Share Posted July 16, 2012 Hi Lekonna, I can confirm that what you think is happening, is happening. You are best to increase your targets that are set to 0 to your minimum boost target. Regards, Phil Quote Link to comment Share on other sites More sharing options...
lekonna Posted July 17, 2012 Author Report Share Posted July 17, 2012 Alright Phil, thanks for clearing this out. I'll do just that. The reason why i've been playing with area that i know the turbo can reach on every weather is because its been very hot here when i've been tuning, and i don't want to run into a situation where in the cold weather i get spool considerably lower than previously and run full boost on a unmapped fuel area, just around the spool-up when the engine is bound to knock the most.
