Installed new engine, and got unsolved problems... Options

[rave2n]

i was just reinforcing my point.


no

Aw, for a second I thought you might find some humor in something. Ah well, beggers can't be choosers.

Do you own a Celica? Or have in the past. I see nothing in your profile. Just curious.

Got more then 80, actually have quite a bit of parts coming in, and magically they cost me more then 80 bucks.../gasp, was hoping you might actually find humour in your "bitter"ness. Why are you so bitter btw? Genetics? Do YOU not have 80 dollars to mod your car? Cause if you don't, you DEFINATELY should not be modding your car. That'll just come back and bite ya in the butt. "Trust me"


Back on Topic: GL sir with your swap, and I hope it all works out for ya, regardless of the flashing and troubles. Hopefully you get the correct ECU in there, and get that new engine running like it should. Props on the swap, and looking forward to more details!

i owned a 93 geo prizm for nearly 5 years that i spent way too much time/money messing around with, it was a fun car and a great first car

now i own a 2000 celica GTS and i've been much more selective and careful about what i buy and don't buy, do and don't do, doing more research and thought before i do things or buy things.


the correct solution to this problem is to install the correct ECU, end of discussion.

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.

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?

contact pheonix tuning and he can make you the correct engine wiring harness to be able to simply plug in the correct ECU. just for ****s and giggles, can you take a picture of your ECU label for us?

Ok guys, it appeared to be 3S-FE (jdm SS-I 140hp) engine instead of GE (SS-II)...(I though that all 2.0 litres in japan where 3s-ge)
So I've got less HP than expected and almost the same torque as GE. Maybe there would be more problems with 3s-ge on 7a-fe ecu...
Anyway, the engine is running very well, got no problems at all, only got 80500 miles on it so it will run many years more I believe
I have noticed that the fuel consumption have raised a little compared to 7a-fe, but that should be normal. And finnaly, the oil consumption is normal, I don't need to refill oil every 2-3 weeks like it was with 7a-fe, that was the biggest reason that I decided to get new engine... 3S engines are the best
The power can't be compared to the GT4 I have with 300hp, but it's definitively feel much faster than 7a-fe

Here are pictures from the ecu if anybody is interested and two pics of the new paint .
also added 7a-fe ecu pinouts pic.

And I got some questions...
1. The exhaust sounds a little more silent than before (when siting in the car) I have the same muffler like before, why is that?

2. On the catalyic converter it was a empty hole, someone says it is for measure the o2 gass in some countries, the workshop welded it.. So what is it for?

3. Is it true that JDM cars have adjustable fuel amount? How to do it?

1. Different engines make different sounds. It's nothing to worry about, but could be effected by #2.

2. There is an O2 sensor that would go in that hole near the cat. If this was left wide open before then some exhaust would leak out there and make the car louder.

3. I don't think this is true.




And I think what bitter was asking is if you could take a picture of the ECU presently installed in your car.
