Topic: EFI ready to install
in Forum: C3 Fuel, Emission Control, and Exhaust Systems


Very nice set up. I like it a lot.
Now if you really want to do this right, run the car on a track or dyno before and after the install, and see what it does.
Keep us posted on this one.

Well its done and running strong. Been tuning on it for the last couple of days and finally have it where it feels good and quick.I know that it needs more tuning ( I think its too rich) for better economy, but the calibration module is right there and easy to operate. The trick you see is knowing what it needs, but with a high lift cam at low rpms, the effects are a little puzzleing to me right now. But when I went up 30% globally on fuel that mother come ALIVE The install went pretty well. Had to cut and braze two fittings together for my heater hose because I needed it low profile so the fuel line would not interfere. The system had a two wire coolant sender and my temp sender had only one, so I bought a thermostat housing with a 1/2" hole and put mine there. Another small thing was the schrader valve was too close to the radiator hose to put on my fuel pressure guage, so I put a 90 deg fitting there. Surprisingly most of the wiring disappeared against the firewall. All wiring was put in black heatshrink or black wire loom. The ECU went under the radio and the plug for the Calibration module was velcroed to the air duct under the dash in front of my right knee. All calibrations take effect as soon as you put em in. There are three places to store calibrations. A,B,C. A is the default when the engine is started. B, and C can be used to experiment with and you can move all of them around. Restore any and save to A or whatever. The base calibration is from a chip I got from Edelbrock and it too could be restored to A,B, or C. Just dont forget to save your calibrations before you turn the car off or its gone. Guess how many times that happened..a bunch! Anyway, it was fun. The batteries in my camera was low so the picks may appear a little dark.
