I bought 3 new rides last week a uforce 1000 for myself a cforce 500 and 600 for my 2 boys age 10 and 13, I want to lower the top speed way way down. I have been on them and watching them so they don't go too fast until the break-in oil is changed after the first 100 miles. I talked with the mechanic in the shop and he said they couldn't correct the fuel map to limit top speed, I'm trying to find out if it's possible I have done fuel map adjustments on cars and trucks via laptop pass-through to obd2 port. My oldest will listen and wouldn't drive too fast my youngest on the other hand is a daredevil like I was. Any info would be helpful
