Installing the Electromotive EFI
Part 4
| The spark plug wires, exhaust gas oxygen sensor wires and most others have been run to the various sensors on the engine. I will leave them all spread out and unbundled until I am sure that everything works. |  |
| The radiator is in place with two electric fans that will be controlled by the Tec-II unit. A K&N air filter and Outerwear pre-filter have been put on the turbocharger compressor inlet. |  |
| A view from the passenger side in front of the engine showing a mess'o'wires. The Tec-II unit is in the bottom right of the picture and the laptop I got on ebay for $20 is on the bench behind the radiator. More on that later. |  |
| A shot looking down at the engine. The two fans will suck air upward out of the radiator and are activated when the coolant temperature reaches 180 degrees. Another fan will be added below the intercooler that will run whenever the engine is on to cool the intake charge. |  |
| While cranking the engine to get oil pressure, the gauge read zero even after I fixed the mis-labeled remote filter mount. I pulled the line off the turbo and tons of oil came out when the engine turned over, yet the gauge read zero. As it happens, brand new brightly anodized fittings and teflon tape did not allow the electric oil pressure sender to be correctly grounded, this clamp to a ground wire is a temporary fix. |  |
| I spent the time to make the Hallman-style boost controller and then I talked with the guy who will tune the Electromotive EFI and he recommended that the Tec-II unit control the boost via a solenoid. This is a pic of the solenoid. The computer monitors the pressure in the manifold and when it exceeds a pre-determined amount (easily changed to meet different conditions) it will open the solenoid and allow pressure to flow to the wastegate. Darn slick if you ask me...... |  |
| Here's three shots of the engine on the trailer on the way to the tuner's shop. I got the engine running, but not very well, and am having a pro do the final calibrations and tuning of the Tec-II software. Even running badly, the rail will easily leave 20 foot long black skid marks on the pavement with a 1/3 throttle launch. |  |
| It will need to have a muffler fitted because the engine is very loud, much louder than I thought it would be. I'm leaning towards a camco fabrications bombshell muffler because the 3" id will match up to my exhaust easily. |  |
| Details of the dyno tuning and the persons responsible will be posted in my next update |  |
