Yes, that is quite notable and leads to the question about the differences between the 65DA1 and 66D1. Perhaps a member with the answer could respond.
I imagine you would get better mileage in Guyana where you are usually on flat terrain compare to St. Lucia where the better part of the journey is usually going up one hill or another (although balanced by the decent on the other side). I have seen earlier 4x4 models with much better performance even in our terrain and this has led me to the conclusion that it is possible to tweak mine for greater fuel economy.
My ECU part number is 33920-65DA1 and the vehicle is an Africa spec. SQ420 with the 2.0 J20A engine - I find it interesting that the same "code" could be used to run two such dissimilar vehicles.
Fuel consumption on my car could be better, but, it's definitely not as bas as yours - I'm seeing roughly 16~18 mpg (US) around town, with a best of around 22, going outside of the city - given the size of your island, I guess your driving might have to be considered as all city driving - oh - I'm in Guyana.
Missed your query in my mad scramble to get more info on the 1902.
I am on St. Lucia and the vehicle is an Escudo of Japan origin; yes one of those! Type GF-TD02W; Engine G16A.
It has given me no problem over the past several years with the one exception that it really drinks petrol. I reckon in the region of 10 to 14 mpg (US) and the current challenge is to improve fuel efficiency. Scanning with RV returns nothing out of the ordinary so I am now pursuing the use of TP V5 which appears to have a wider range of diagnostics.
By the way, the ECU box is labeled 33920-66D1(0) and made by Mitsubishi. In my search of the net the "66" boxes appear to have been associated with the Chevy Tracker which I believe are for the US market. I am hoping this will be useful in accessing the ADX and other files required to really do a good job on the vehicle.
How is yours performing? at least I now know of one other 1902 box out there!
