Ezgo txt Golf Cart Throttle issue

[Russter500]

Hi everyone! im super new hear and was hoping i could find some help or advise with a cart. It is a TXT Ezgo electric golf cart(unsure of year as the description label has been removed) With a Curtis 1206mx speed controller. we recieved the cart not working, we replaced the batteries and it wouldnt move. We tested the throttle switch and ITS and had good readings, and we ended up finding that we were able to jump the solenoid to get power to the wheels. So it seemed like the speed controller wasnt reading the throttle signal so we came up with a bypass. we used a relay, spliced that in with the throttle switch, to bypass the Speed controllers circuit, but also have the computers throttle switch inputs connected to trick it into allowing throttle. Sorry if this is confusing to explain, we arent very experienced with this stuff and are figuring it out as we go. The main issue now is that we got it to work, but it seems pretty slow, maybe 5mph. And it seems to intermittently get out of limp mode and go twice as fast. We cant figure out what causes it, but we are thinking maybe the computer wants to see a certain delay between the throttle switch being pressed, and the ITS signal. if anyone can shed any light on this that would be great! thanks!
