Hi guys,
Are there are any tuners that specialize in road course/autocross driving i.e. non-drag specific applications? I have a 6R80 auto transmission, which I know isn't as good as the manual would be for what I want.
However, I'd like to see who tunes for this kind of thing. Let me preface this by saying I have a Lund flex fuel tune with 18 manifold and 47lb injectors - stock headers and cats. I always drive the car in Sport (manual) mode, so I don't care for the regular D mode at all. I like to rev the engine up and select my own gears. In fact I hate the D mode because it is so bad IMO. It literally neuters the car and shifts way too early.
*I have noticed something on my car which is annoying me. After a hard or moderate pull, the engine will go into coast after I let off the throttle, say at 4-5,000 RPM when I do not want it to. I am expecting engine braking/fuel cutoff and instead the car keeps carrying momentum. This can be disconcerting approaching a corner on the street and expecting deceleration and not getting it. It actually feels like it is pulling me forward. I don't want this happening on autocross or road course event. It seems like some sort of cat protection logic in the ECU perhaps? Where it wants to continue dumping fuel to cool the cats down? That's just a wild guess. And it happens even after short bursts where I feel like I am not even pushing it that hard that this should happen. At any other time at that RPM, the engine will go into engine braking/fuel cutoff as I think it is supposed to. So why does it always happen sometimes? I know that in very low rpms the car is programmed to coast sometimes, but I don't think it should be happening in gear at 4,000/5,000 rpm
I have emailed Lund about this and I understand their tunes to be more drag-specific or drag oriented, which is totally fine. Just wondering if I should consider a different tuner and who to go to. It also wouldn't hurt to have a more linear throttle feel and more controlled downshifts/upshifts. Any advice for me as to what you think is happening and if I can do anything about it?
