galapogos01 Posted February 24, 2018 Share Posted February 24, 2018 Hey guys, Love the ongoing work on this software. The Howto guides you have added here are excellent, short and to the point. Would love to see some for the 5.0, maybe on the factory throttle limit? Cheers, Jason Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted February 28, 2018 Share Posted February 28, 2018 Hi Jason. I've never tuned a 5.0 before, could you explain what you mean by throttle limit? This is something that would be good to get a community response on. If you know anyone else who knows more send them a link, once we get enough info we could compile something.

Sam Posted June 12, 2018 Share Posted June 12, 2018 From what I'm lead to believe the throttle in an FPV GS is limited by the tune to how far it can actually open. Been a while since I've actually looked into it, but from memory it's limited to roughly 70% where as the GT was around 80%. They are the two figures that jump out at me when I'm trying to think back to what I found. 1 Quote Link to comment Share on other sites More sharing options...
Sam Posted June 12, 2018 Share Posted June 12, 2018 After some light reading I believe that the GS max throttle angle is limited to 50 degrees and the GT is limited to 60 degrees?? (someone may be able to confirm and correct me on those figures) This can be increased to 80 degrees, however caution needs to be taken when doing this as some other parameters may need to be altered, ie spark etc. TPS calibration may also need to be played with to ensure it stays within it's limits.

galapogos01 Posted June 12, 2018 Author Share Posted June 12, 2018 If we can confirm which other parameters need to be altered, it'd make a great how to guide to add to the ones in this forum. Quote Link to comment Share on other sites More sharing options...
Sam Posted June 12, 2018 Share Posted June 12, 2018 I've never done it myself but I would assume you would have to remove some timing to compensate for the added air and the amount will differ from car to car. Not 100% sure with the TPS side of it but when I have a chance to get on the laptop I'll have a look at what parameters I think it would be. I think its something like max voltage for TPS and something else. Quote Link to comment Share on other sites More sharing options...
Sam Posted June 13, 2018 Share Posted June 13, 2018 So the tables that needs to be adjusted to allow the throttle to open up to 80 degrees are auF0083 -Throttle Angle (Pedal Position) & auF0084- throttle Angle B(Pedal Position). Quote Link to comment Share on other sites More sharing options...
galapogos01 Posted June 13, 2018 Author Share Posted June 13, 2018 Thanks. What are the B maps used for? Quote Link to comment Share on other sites More sharing options...
Sam Posted June 13, 2018 Share Posted June 13, 2018 Not 100% sure sorry Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted February 13, 2019 Share Posted February 13, 2019 FYI I've put some more information regarding this here: 1 Quote Link to comment Share on other sites More sharing options...
galapogos01 Posted March 9, 2019 Author Share Posted March 9, 2019 (edited) Thanks Rolls, some good insight to be had from those comparisons. I was wondering whether you had any more info on the Decel Fuel Shut Off. The Params seem to have slightly different names (coasting fuel shut off, DFSO, fuel shutoff, decel fuel shut-off, CFC, DFS) which makes searching for them hard as there's no common term. Not all are grouped in the Coasting Fuel Shut Off top level either. In particular do you know anything the references to 'profile correction' ? The 5.0 seems to re-enable the injectors when coasting at a much higher rpm/speed than the 6 cylinders, I'm looking to correct this to help with city cycle economy.

Roland@pcmtec Posted March 9, 2019 Share Posted March 9, 2019 Good questions. Most of the parameters can be ignored. I will write up which ones you need to tweak and some more detail behind how the system works. The different terms refer to different parts of the fuel strategy so it is definitely confusing. 1 Quote Link to comment Share on other sites More sharing options...
