Hi.
This week the workshop finished swapping engine (3s-ge) from a JDM ST202 into mine AT200 (7A-FE). The whole exhaust incl. the cat was also swapped. The new engine only had 80000 miles before the swap. Almost everything seems too be fine except this: 1. Rough idling and very poor engine performance (feels like 60hp). Engine gets very warm when driving. Also when the engine is cold and I start it, I have to give some gas in the beginning or it will shut down. The muffler is also making abnormal noise. 2. Fuel gauge is showing lowest position and yellow lamp lighting. Before I delivered the car it was showing half tank. What can be the cause for these problems and where should I start for solving these problems asap? The ECU hasn't been swapped yet. And sorry for my bad english..

If somehow out of the blue, your Mechanic was also an Engineer yeah I believe it was flashable, but at this point where your car is running like a champ that just lost his belt. I don't think so.

I don't think so. The ECU was not flashed by the mechanic, but he knew a specialist that had the equipment that was needed to flash the ecu... At this moment, engine behaves totaly different compared to 7a-fe software. The acceleration is much better than it was with the previous engine, the cooling is working, there's no more rough idling and everything else seems to work like before. I had no other choice than change the software, no one would take the job swaping the wire harness and ecu. I'm not convinced yet that changing the ECU right now is nescerary since I got no problems so far, but I'm willing to try out swaping myself of curiousity. I'm not a mechanic and not a electrician, could I swap this on my own or is it very difficult?
