I have AEM EMS that I have used since this spring. This week I changed the engine in the car, and everything is working except one thing. The temp gauge... When I start the car, it says just one bar which is normal. Then after a couple of seconds, it just lights up all the bars. What can be the problem here? Before I installed the Modifry fix, the temp would just stay at one bar, which makes me think it's not the modifry fix (but of course I'm not sure). Could it be the engine temp sensor?

The car is an MY'00 AP1, with F20C.

 

Found it out already.. Checked the Modifry ECT wiring diagram again, and found out that I had forgotten to t-tap two wires to the EMS. Did that, and then it worked like it should again. When we changed the engine, we changed it with the engine wire harness as well as it was on the new engine too. So I just forgot that I had to tap those two wires like the other wire harness...
