Bought a tuning box off a member on here. It's been working fine for a month or so. Then the other day, got in the car, it started but immediately cut out. It did this 4 or 5 times. The only way the car would not cut out was by maintaining high revs.

Took the box off and started it, car ran fine. Put the box back on, same issues. Spoke to BlueSpark who (very nicely) agreed to remedy this if I posted the box back to them. Been over a week with them now, and not heard anything. Anyone else had any isues with this box? It's on our 180BHP SuperSport..

I had a similar problem we have to remember that these digital boxes are running a processor and can sometimes go wrong, I did the same as you and got the same results ;-)
