BPU'ing my stock Supra after a year of ownership and have ordered decat pipes, exhaust, fuel pump, boost controller. I recently bought a second hand HKS FCD and was looking through the install guide and couldn't help but read all the negatives about it ruining the voltage signal and that it was 'the worst kind'. Then other people say they've had it for x amount of years with no issues?
I thought most people on here running BPU have this unit fitted?
Has anyone actually had problems with it?
What other options are there for the stock ECU?
Or is it fine and I should just go ahead and wire it in?
