ok i just picked this car up its got a sohc zc in it but a still has the dpfi on it for some reason but has a pm6 ecu ok the car will not go past 3200rpms it hits 3200 and sounds like the rev limiter is hitting any ideas what thsi would be.

codes 4 tdc sensor and 14 injectors comes up on the ecu

You need to go MPFI, or get another ECU, a DX ECU.

dude your all messed up, just get a pm5 dx ecu, or convert to multi point...just like he said ^

90hatch

yeah like i said i just bought it and i was like wtf when i pulled out the ecu cause i know its not sapposed to have that ecu so i hope thats my prob what you think

That was probably it. Get the ecu or switch the fuel injection. Do one (or both) and see what happens.

my cars a 4spd so does that still use the pm5 ecu

doesnt matter what tranny it has unless its an auto

if you have some mechanical skills and feel comfortable swapping an intake manifold and dizzy I would do a mpfi swap, you'd get better performance that way.

For the price some people want for an ECU even a dx ECU you might as well complete the MPFI swap, that is if you feel confortable with it. Check to see what Distributor you are running also. Is it an Si or Dx?

If it is a Dx, or one for the DPFI system, all you need is the PM5 and should work.

But if the person was trying to do the swap and also swapped in the Si/Hf MPFI distributor, just changing the ECU will not work. You also have to check the wiring, if they infact changed the wires already for the MPFI swap, then they would need to be changed back to work with the DPFI system.


It might sound complicated, but it's not that hard really.

ok the cars is still dpfi and is still running a dx dizzy so what im getting at is since the stupid person that did this put a pm6 in it does this sound like my problem, and im not gonna go throw doing the mpfi because the cars not really worth it so alls im getting to is do you think this is my problem at 3200rpm
