Roland@pcmtec Posted February 13, 2019 Share Posted February 13, 2019 A few people have asked how to remove the throttle limit on the 5.0L supercharged vehicles. A good way to start with these kind of problems is to compare the FPV or Sprint calibrations to a stock calibration. Eg a FPV 351 auto calibration is HAFJ1K2 and a standard 5.0L auto calibration is HAFH5HB Here you can see the following tables have been tuned by Ford. Desired throttle angle (auF0077) increased from 419 to 579 Throttle Angle auF0083 has been increased from 60 to 80 Throttle Angle B auF0084 has been increased from 60 to 80 IPC conversion of percent accelerator pedal angle to desired throttle angle auF12514 Delta pressure across the throttle plate auF10980 1 Quote Link to comment Share on other sites More sharing options...
Gonads Posted February 26, 2019 Share Posted February 26, 2019 Hi Roland. Great info. I noticed the same thing with throttle angle by comparing my GS file to the FG-X XR8 Sprint file. I just tried to download the HAFJ1K2 calibration and it doesn't seem to be there. Do you know of another FPV 351 calibration that I could download to compare to my GS cal and the XR8 Sprint calibration (HAFK0XB)? The XR8 and FPV351 are probably very similar but I'd love to compare them just to give myself a bit more confidence before uploading the modified calibration. Thanks, Ben Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted February 27, 2019 Author Share Posted February 27, 2019 It seems to be there for me. Did you get an error when it failed? Can you try again? Quote Link to comment Share on other sites More sharing options...
BDAZLA Posted December 18, 2019 Share Posted December 18, 2019 Can you make the 80 to 100? Is it percentage based? Would it affect anything else if I made it 100 instead of 80? Quote Link to comment Share on other sites More sharing options...
BDAZLA Posted December 18, 2019 Share Posted December 18, 2019 I have copied the gtf tune into the fgx xr8 tune already but would like to improve on it a little bit Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted December 18, 2019 Author Share Posted December 18, 2019 I'm not sure if there is a mechanical stop on it but if not it will just spin around the other way and end up being partially closed again. The 80 is meant to be degrees but I believe it is an arbitrary angle. Best bet is to just take the intake off and look at how far it moves. I think there is an ETC test procedure in IDS/Forscan which will cycle it with the engine off. Quote Link to comment Share on other sites More sharing options...
Gonads Posted April 16 Share Posted April 16 Hi Guys. Has anyone has taken the time to remove their intake to observe the throttle opening angle when using the 80% opening map for auF0083 and auF0084, as per the GT, GT-F and FGX XR8/XR8 Sprint: For comparison, this is the map for the stock GS315: Seriously Ford - 50%!!!!!! In a perfect world, Ford would've let the GS open the throttle fully and finished the development of the Miami/intercooled option for the GT. Another way to look at it - I've never gained 20+ kW so easily! I'm really interested to hear opinions about running the throttle map below (95% throttle opening), with a calibration that is a hybrid of my stock GS and parts of the FGX XR8 Sprint: Thanks for reading this far and all opinions are warmly welcomed.
