Of recent time ihave been having quite a few issues with my D4D going into limp mode anything upto 5 times a day, so i emailed Troy at tuneit to find out if they new of the problem and was told to bring my vehicle to them in southport on the gold coast as they have seen this problem with quite a few D4D hilux's.
He totally removed the chip and harnes and fitted a diode to the wiring harness as apparantly they have a tendancy to get voltage drop issues which causes these problems.
As well as modifying my harness he also loaded up all the latest tunes which he told me would help eliminate the cold start rattles.
Well after quite a bit of driving last night and this morning no limp mode and by now it definatly would have done it atleast once or twice and to top it of cold start rattle is alot better and better performance.
Didnt charge me a cent, pretty bloody good considering i bought the chip 2 1/2 years ago.
Wonder how many of the other distributors would provide that level of service.
Thanks Troy im a very happy customer.
Cheers Sean
