yet another FD noob
i just got a FD! *cheers* but it runs like S,i thought it was 3800 hesitation but im not sure,if i barely touch the gas the rpms will raise just fine,but if i try to get into the boost the rpms stick and lots of fire shoots out the back,the guy i bought it from replaced the ecu the day before i picked it up,this is my first turbo car so im no clue what could be wrong with it.go easy on me fellas

What ECU did he put in, stock? What mods have been done on the car? Does it still have a pre-cat?

sounds very possible,the description of the car said it had a turbo xs boost controller but i cant find it anywhere,but i also havent been in the car in daylight yet,would it be worth a shot to try unhooking the battery and seeing if it might have been limp mode?

I think you should just find the best qualified rotary shop you can.
Literally being in the dark on a car of this complexity with mods installed then removed could leave you anywhere. Only a well experienced shop or mechanic could reasonably be expected to sort this out.

I had the same problem when I got my last T2, It will rev fine in neutral but when trying to drive it just wouldn't move and backfire. Turned out the motor was blown... Get a compression check. Since the car has a streetport and exhaust on stock ecu, may be pushing it. Does the car have a intake? How about a midpipe? Could try to reset your ecu if you think thats the problem. Worth a shot.

Am I wrong to think that an FD that has been converted so that it's turbos are non-sequential, a street port, and an unknown hi-flo exhaust would tend to need something other than the stock ECU?

Stock ECU is really being pushed with exhaust mods. I would put money on a blown engine based on the mods you listed on stock ecu. I have been surprised by how stout the FD's engine is, so I think you should quit driving it untill you have someone figure out the issue.(you might get lucky)

Maybe it could be the map sensor then if it's doing it under boost? Try resetting the ecu and check the map sensor it should be on the firewall right by the UIM.

Try checking for codes. Heres a link on how to do so.

Sounds like the solution to your problem is about to slap you in the face if you keep ignoring it...
Take your car to David, let him sort it. Thank him afterwards then spend time learning about these cars before you do anything dumb. To your car, yourself or those around you, please...

Im not talking about the boost. A ported engine with stock ECU cant be good. No one knows what the previous owner could have done to the car. Its not the 10psi boost I think is the problem, its the street port with the combination of a downpipe. I have seen people with similar mods on stock ecu and no problems. I have also seen blown engines from mods like this on the stock ecu. If he has a boost controller like I red he did how do you know the boost was kept at 10psi or under. I know a kid who installed a boost controller on a perfect bone stock 94 R1 and set it to 15psi, within a week he was at Defined Autoworks getting a new engine. Im just saying it's possible and worth a compression check. I know 10psi wont hurt the car but 15 could.

However, a streetport on a stock ecu is not dangerous if kept under 10lbs. In some cases you will get a really rich condition at idle and notice some fuel smoke/smell on cold starts and if the idle is set around 750-850. This is all from personal experience and realize each car reacts differently to mods.
