Note: These finding are based on the Starter 21 Ktuner versus the +6 Hondata CARB tune...
I really like Ktuner but there is one wrinkle in driveability I'm not too thrilled with...
Around town in the suburbs or in city stop and go, Ktuner wins. The reduced lag is really noticeable and power comes on quickly. I'm sure it has to do with the improved throttle response and aggressive boost ramp I'm using.
Where things feel different, is on the highway, which is where I do most of my driving. In normal highway driving both tunes are just fine. But at high speeds when really pushing it I actually prefer the feel on the Hondata tune. So today I was accelerating from about 65mph and gave it about half throttle and was at about 4,000 rpm... and then decided to go WOT. I was expecting a real whoosh of power as I approached 5500 rpm but all I got was some mild sense of accelerating. The speedo was climbing but the sensation of speed wasn't really there.
With my Hondata tune in the same scenario, there is a huge rush of power at 5500 rpm, almost like a vtec kicking in feeling. I simply don't get that with the Ktuner setup I'm running (everything set aggressively). My guess is it's the aggressive ramp I'm using versus the fact Hondata uses factory ramp.
How would I set up my car to have that great around town lag free feeling with the aggressive ramp but have the boost ramp up a bit slower after 4,000 rpm? If I set boost by gear with ramp in the higher gears, would that work?
