Yes, I went ahead to get my mpfi swap done on Christmas eve.
First,
I changed out my DX camshaft to the SOHC ZC one. It has a slightly higher lift and longer duration. It was the easy part.
Second,
I did my wiring as per normal with a TD02U
For distributor wiring, I am also running a MSD external coil and ignition box. From the ignition box I have two wires spliced to the black/yellow & blue wires on the 2-pin plug. I got all the wiring done for the 7-pin plug. Added orange and white wires instead as my DX dis had blue/green and blue/yellow wires. My DX ecu also has blue/green and blue/yellow at C1 & C2.
For the injector wiring, I soldered the black/yellow wires from the two DPFI injectors to the single black/yellow wire to the resistor box.
After about 5 hours of labour, we turned the key and there was blinking at the ecu. Tried to start but can't. Suddenly, we found gas leaking at the fuel rail and radiator coolant running into the cylinder nearest the radiator water port. WTF, I thought I am going to trek 6 miles home. After an hour of removing the previous manifold bracket, tightening the intake manifold and fuel rail connections that problem was solved.
However, there was a problem with starting the engine, apparently there was no spark with the MSD coil and ignition box connections, the clear cap gave a good indication of it. I have no choice and de-wired the MSD components and use the stock internal coil and cap. Managed to start the car. However the check engine light came on and the ecu still gave out 5, 6, 10, 13 & 20 short flashes. I took the car for a spin despite the problems. The sound was different. My previous DPFI was higher pitched. The MPFI with the much larger throttle body gave out a low growling sound and was incredible at high throttle. However, I was rather disappointed at the low end torque. At which rpm, I do not know because my rev meter is dead. Is it some wrong connection? I also have some problems with the vacum hoses. Any kind soul willing to guide me on this one?
However, I managed to drive home despite the check engine light and celebrate Christmas with my family.
Merry Christmas everyone.
