Although I dont have big injectors like M6s, I have run 100HP, 50HP, and the current 275 injectors with the Smarty, and admittedly it is fun at first to have the instant responsive throttle. you soon realize that basically youve lost the dynamic range of the go pedal and have had the full range compressed down into less travel to do the same thing (depending on the SW level). For me it has become annoying.
At least the Van Aaken box I had before didnt really add fuel until you pushed the pedal down a bit still leaving a smoother more controlled response off the bottom.
I too have gone back to stock ECM programming and the Smarty is on the shelf in the garage just to see if we will receive some updates to try out soon. Otherwise, itll be another item in the classifieds.
Im very dissatisfied in the way us 2nd genners have been ignored. We cant even get an ABS adjustment for a stock SW! Ill probably end up going back to the Van Aaken which was an excellent timing box (similar to the EZ) and recoup a few hundred bucks as well.
I am guessing you have tried SW3 or SW2?
The Catcher SW is not used for SW1, 2 and 3. Although I don't really know how the Catcher SW works, it definately can add some smoke (fuel) at low RPM's. From what I can "infer" it ignores boost and possibly even retards the timing a bit at those RPM's to increase spool up rate. I am guessing that Catcher compresses the loading curve vice the APPS curve.
On any Cather SW my truck makes only smoke below 1500 RPM / 5 psi of boost. There is very little power there, but this was not always true. When I was running stock injectors with the HX35 it made good power from the ground up. It could still pollute cubic yards of clean air (I ran SW9 in those days). Now however, with the M4's once the turbos start to spool the power is very smooth and no smoke. I mean zero smoke. (I should try stock just to see how much different that would be. )
When I was running the Ottomind (boost fool fueling and timing box) there still was no power there and no smoke too. When the power did come on, the torque rise was really excessive and my drive train would just howl. What irratated me was I had not moved the throttle a mm. At least the Smarty lets me control power (and smoke) to a larger degree.
The only guy I know of that uses a Smarty with big air / injectors is MikeD over on DTR. Don't quote me, but I believe he can run in the 11's. Last I read he was using SW3 still and runs fastest on that setting.
Reading over on NWBombers, Marco is not ignoring 2nd Gen. He is busy working on 6. 7 stuff. He might actually have to make a living with these products. Support a family maybe? I could only imagine it is no hobby for Marco. Marco, probably understands us bombers vote with our $$$.
Marco is planning to come to US in the coming months. From what I read, his plan is to explore and refine some of the 2nd Gen SW's. Evidently, there is a few more trucks on this side of the Atlantic with different issues / demands than the ones that are over there which have no issues / contentment.
I also think that if Dodge quits building new engines / electronics that us 2nd Gen'rs (3rd's and 4th's also) will be sitting pretty. I am not ready to give up on the Smarty just yet. In the mean time, the new soon to be released Quad looks promising to me as well.
But... .
I only wonder how long it will take for that
new and improved Quad box to drop out of favor just like so many of its predessors have?
