Hi all
I was wrong. There, I said it. Wrong diddley, wrong wrong wrong wrong.
As some would know I have been most vocal on the 'dont fit a chip" discussions in the past.
I was at the 4wd shop the other day handing over another wad of the folding stuff (well buying stuff for the work trucks) and the sales manager makes me an offer on the last of his dtronics that he had in stock for a prado 120 with the 1KZ.
We argued politely for a while and he made me an offer. Cost price and if I dont like it bring it back.
So I figured I will keep it for a month and then bring it back.
Anyway here are the results.
(Before fitting I put an exhaust gas temp probe in the exhaust beneath the dump pipe. Not an ideal spot and it will be relocated when I get time. i was after a baseline temp)
Filled the prado up and did a full throttle run to 100kph up a steep hill out of Hobart (Southern Outlet sth of Kingston on the way to the Huon). Fitted the dtronic (passenger kick panel - easy fit just plug and play) and did another run up the hill.
It was a full 4 seconds faster than standard. Off idle response is much much faster and hills are easier to tackle. Whats more the annoying flat spot that developed when I fitted the larger tyres (kind of like it was dropping into OD too early) was gone. So it is definitely pulling better.
I did a fuel economy test over the two tanks of fuel and filled up after 1308km. Previous fuel economy was 13.6lph. New fuel economy was 12.8lph.
Better by .8 per litre.
And there has been no difference in Exhaust Gas temp (though I havent towed with it yet).
And there is no additional black smoke out the back.!
