Turnaround time is only 1-2 business days!ĭHM is here to offer you the original flash tuning solution for the Honda Grom / Monkey! I don't know if anybody tried such on a GW and the lack of interest in Guhl may be the reason why.Īre GW owners just old men? LOL!.i am but I still enjoy spirited rides.**Mail-in ECU to DHM. It was a huge improvement! 88hp jumped to 103hp! This is also with a custom exhaust offered by the same tuner of which eliminated the Cats. My 2014 Moto Guzzi 1400 Custom is similarĬhanging the fuel map encryption is near impossible.Ī tuner in California figured out a way by writing a fuel map and piggy backing it with a Dynojet Power Commander. You could add a piggy back but that is just a band aid. It ran and sounded superb BUT nobody was able to crack the Honda encryption to modify the fuel map. The catalytic converters are in the ST's mufflers.(GW are in the header pipe). I had an 2005 ST 1300 with a K&N air filter and Two Bros mufflers. Hopefully someone will come out with a tablet tuner with several fuel maps and the associated mode adjustments. Yet then we still have that constricted catalytic converter exhaust. Et al.Ī tune to match a better air filter would be nice. Nevertheless, a good tune makes a bike better. This is the main reason I went with the GW. How on earth do you detune an 1833cc engine to 15 hp per cylinder? Hopefully Bren Moto finds a cure for this lethargic walrus of an engine. I would not be surprised to see 10 HP in the 5500 RPM range. This bike will gain power with a 93 octane map which has optimized timing, added fuel and requires the use of a Sprint or K&N filter. I went to Don about adding fuel but he was upset that the sales of his flash were super low and that he did not want to pursue further development of the tune because of the lack of sales. What he did not address was FUEL! During my passes at the track, my Goldwing ran best in hot weather because the bike was running super lean at wide open throttle, especially with the K&N filter. Guhl's flash raised the timing in the 1st three gears, raised the Rev limit to whatever you wanted (I chose 7,000), made the temp fans come on at 190 degrees I believe, the bike was running super lean at wide open throttle, especially with the K&N filter made sport less twitchy and tour mode more twitchy. I'm the guy that went 11.95 mph at the dragstrip with my Goldwing on the Guhl flash.
