It would help if you guys would actually look at what Penner has done by comparing his tunes with the stock tunes. First, Penner added fuel in the mid range to all of his tunes. Elsewhere he noted that the high end had enough fuel in his unrestricted map. In the US tunes, the ignition in gears 3-6 is advanced up to 3000 rpm from 3.6 to 47.5% throttle and to 3500 rpm from 59.5 to 100% throttle. The ride mode tables are all less restrictive, depending on mode, rpm and throttle position and set to 100% at full throttle in the road and sport modes. The US R and GT maps are nearly the same - Penner added fuel to to GT L tables in the mid range. This isn’t relevant because the F-L switch is at 4% throttle. The All Market Penner maps, to which Richard is probably referring, are a different story. For the R, the F fuel tables are enriched in the mid range as with the US maps. However there is no change to the ignition table I(3-6). Only sport mode is completely unrestricted at the top end and less restrictive from 11.8 % throttle and higher. The GT rain and road mode tables appear to be reversed, at least in the maps on the Tuneecu.net site. Remember that these tunes are free. Anyone can remove the speed limiter
