I recently had a tranny swap done to my car. It was an automatic and I had it converted by a shop(rallitek) to a manual. Well the swap was great, and it shifts perfect. But heres mine(and the shops) problem. I cant get the rpm past 4500. It throws an engine code, something about the speedo. And yes the speedo does not work. They tried to wire the speedo directly to the ecu, but that is not working and that might be the problem. They are kinda stumped and need some time to think about it, but I was wondering if anyone here had any ideas about it. It was done to a 99 sus legacy. Any input or things we could try would be very helpful.
