I see your point. I guess I'm thinking is that VW wouldn't have made
an engine lid like I (and others) have. Like VW would have left more
room between the box and the engine. I "cut" mine kind of close.

Maybe I'm "seeing" things wrong in terms of air flow, but I just can't
see much, if any, air flowing around the parts "contained" in the box
I made. If I'm not mistaken, in terms of the 15* swaps, it seems most
swappers have done a 1.8 Digifant. It has a much smaller intake. That
ABA crossflow intake takes up a lot of space. I haven't seen much
documentation on the swap I did so hard for me to know whether or not
I've created a dead zone for air flow.

But then who am I to disagree with a much more experienced person such
as yourself!      :)

A thermometer of some kind (Jim Akiba has done this IIRC) on the
engine lid will tell me more.

Good idea. Thanks.

I've driven with the lid off before. Not an enviable task in hot
weather, but for the sake of diagnosing and possibly R&D for the next
guy, why not do it again!       ;)

I've checked the codes many times. Consistently I get:

VSS, ECT.

VSS not installed. ECT? Wires from ECU connector to ECT sensor are ok.
Swapped sensors, no change. In terms of the wiring harness itself,
back when I was adapting it to the Vanagon, I noticed, and thought
about a lot, a note in Bentley regarding "California only",
"non-California", or "all" models up to or from 9/28/93 (My donor
harness was from a '93) showing + to pin 3 of CMP sensor on
distributor either came from pin 1 of throttle position sensor, or
from the + buss of the FI's. (via ECU power relay ign. on + wire). But
I think all that is fine as wires to/from the TPS and CMP check out
and I can't see how that would affect the ECT sensor. Plus the engine
basically runs fine.

Meh.     ;)
