G'day from Oz I have had this ECU (I assume it is a G1) running my 1UZ-FE in the boat happily for many years and has been very reliable. I have recently bolted a blower on top and obviously need to do some tweaking, i have got a tune that is running the same set up on a similar boat that I can dial in but the ten dollar question is are these too old to be PC programmable or do i have to dial in manually on the hand controller? I know the general advise would be to upgrade to a current ECU, which would be nice but am trying to avoid the cost and work of starting from scratch.
