Man that really sucks, nothing you can do about it either really... One of my mechanics customers put in his 6.8L chev powered landcruiser to get new tyres i think, and when he got it back, his 1st, 2nd, 3rd synchros were destroyed and the clutch non existent... they said it was like that when they received it....
With my silvia and the microtech, i have, well lost it now cause of stupid battery. But will put it in again as a separate memory, a rev limit at 3000rpm where it cuts injectors to 0%... No more thrashing for those punks.. and chances are the ****ers dont know what they are doing with ecus... and can just easily disconnect the handset so they can't get to it .
