Matt Dunn Posted March 26, 2014 Report Share Posted March 26, 2014 Have a G4+ Storm and plan on trying to use the 2D launch RPM. Â Â The Launch RPM activation table spans from 0 to 60 kmh. Is this adjustable as would really like to span it up a bit more to 70 or 80 kmh.?? When I right click it the axis setup is not highlighted and cannot be changed?

Simon Posted March 26, 2014 Report Share Posted March 26, 2014 Hi Matt Currently we have a couple of bugs around the 2D option where it does not exit the limit correctly. I would suggest in the time being to use the 3D option even if you only effectively use a single axis. Quote Link to comment Share on other sites More sharing options...
Cnstman Posted May 8, 2014 Report Share Posted May 8, 2014 what exactly is the bug? Â Does this apply to Vi-PEC I88 plug in's as well? Quote Link to comment Share on other sites More sharing options...
Cnstman Posted May 15, 2014 Report Share Posted May 15, 2014 When will the update be released? Â Does this affect the Vi-Pec I88 plug in? Quote Link to comment Share on other sites More sharing options...
Matt Dunn Posted May 16, 2014 Author Report Share Posted May 16, 2014 Ok so I think I have figured out how most of it works, but I dont understand how to work out the RPM for the Launch RPM tables? I would rather work it out and have it close rather then alter it at the track rather than start from scratch at the track. The help file says So as an example, to find the RPM value for 0% slip at 25 kph, assuming the digital input has a calibration number of 260, and the un-normalised gear ratio is 169.3:  0% slip RPM = (Speed x Cal x Ratio) / 360 = (25 x 260 x 169.3) / 360 = 1100450 / 360 = 3057 RPM So the calibration number will be the calibration number for the driven wheels? and the normalised gear ratio, is that the gearbox ratio in 1st? or the gear and diff ratio's? The speed sensor is driven from the back of the gearbox, not the actual wheels, does that make a difference? I am unsure what the normalised gear ratio is? 1st gear is 2.3 and diff is 4.3.  Cal number is 275 for rear wheel speed    Quote Link to comment Share on other sites More sharing options...
Simon Posted May 21, 2014 Report Share Posted May 21, 2014 HI Matt Im a little confused as to how you are using the 3D table. What to you have your X and Y axis set to? The Normalised ratio is normally set for 4th gear as 1:1 but you can chose which gear you want to represent as 1:1. Â Quote Link to comment Share on other sites More sharing options...
Simon Posted May 21, 2014 Report Share Posted May 21, 2014 Yep 88.8 is the figure you are after. Quote Link to comment Share on other sites More sharing options...
Simon Posted May 26, 2014 Report Share Posted May 26, 2014 Gear Ratio = Engine Speed (RPM) / Speed sensor frequency (Hz) Quote Link to comment Share on other sites More sharing options...
Matt Dunn Posted July 22, 2014 Author Report Share Posted July 22, 2014 I have had a play at the track and ended up going back to a single launch RPM, and using a 4D ign map with slip on one axis to help as well. I found that I could get it to feel like it was taking off really well, but will only be able to tell in a proper race situation if it is any good against other cars off the line. I ended up with a RPM of 4500, but If I tried 4600 all I got was wheelspin, and if I tried 4400 it would bog down and I would need to dip the clutch. Just hoping for more consistancy, and I am 2wd and race against mostly 4wd's, when I got a good start I could match them off the line, but would only get a good start 1/2 the time as it was very sensitive on launch rpm. I take it that 100rpm is the minimum amount of change allowed as it would not let me enter 4450 or 4550. Matt   Quote Link to comment Share on other sites More sharing options...
