What you should do is wire both ECUs with a switch at your gas pedal toggling between the two. Anything below say 75% throttle, you run the stock ECU, but when you put your foot in it, you switch to high performance. You could also have a manual override 3 position switch on the dash for either "all stock", "pedal switch dependent", or "all mod"... :-)

and thought I would report in to the list. After a 500 mile round-trip to
the Shenandoah National Park this weekend, I am still amazed at the hp gain
using this new ECU. I am running a stock Boston Engine 1.9l with the new
ECU, intial timing set at 5 BTDC and running regular gas. It was much
easier to stay with the traffic flow. I did not have to anticipate
upcoming hills. In this respect, it is much more driver friendly. No more
70+ mph runs at long hills to end up doing 50 mph at the top. The only
downside is the mileage. On the same trip back in June, I averaged 21.5
mpg. This time 18.6 mpg. That is a major hit. I figure it cost me 3.5
more gallons, or about $5 to make the same trip. Is it worth it? I
wouldn't go back to the old ECU. I can now pull out with confidence. I
can zip from 55 to 75 if I need to.
The mileage does seem to be better around town. I picked up about 1 mpg on
several tanks I ran through going back and forth to work. Pulling off in
2nd gear seems more natural. I can upshift sooner. Third gear pulls much
better. If you use your Vanagon as a daily commuter, I would certainly
recommend it.
I plan on tinkering with the AFM to see if I can recover some of the
highway mileage. I have not done an emission test yet, either.
