ECUMASTER EMU BLACK is a universal engine control computer that manages the operation of spark-ignition engines, and is designed to work with the most advanced and complex currently available engines. It is the successor to our proven system, the ECUMaster EMU. Common applications for the EMU Black are modified race cars, passenger cars, motorcycles, boats, and stationary engine applications.
Notes:
Finally got my 2nd gen swap running on ECU master black emu. Had to cut the flywheel with more teeth for the crank sensor.
Found on FB for used cheap.
ECU master has the crank trigger decoded but for some reason it wasn’t working properly for me, so I made a better trigger pattern.
Finally got a chance to dyno the swap today. I decided to spring the extra $10 for an AFR reading since my EU is disconnected. Grand total: $30 for two pulls. Same shop/dyno I used for my previous pulls with the 3.0.
1. ECU pinout for 99 is much different than 95-98’s. Regarding installation of the EU, pin 44 needs to be changed to pin 46.
2. Jumper Pin 13 must be set to OPEN (not 1-2 as shown on page 27 of Dan’s writeup), otherwise your fans will not kick on and your car will overheat. I’ve tested this. Thanks for the footnote Dan!!
3. The 99 FSM is all screwed up, so don’t go by it. Hours and hours were wasted trying to figure out the 99 FSM and compare it to the other year FSM’s I have. The 99 FSM led me to believe that 3 pinouts had to be changed at first. Before I hacked or cut a single wire, I did a continuity test (per Dan’s recommendation) and figured out which wires were really what. Only one wire on Dandy’s ECU diagram had to be switched as stated above.
4. My Emanage Ultimate is version D. I don’t have any CEL’s!!
This illustrates that resistors don’t need to be soldered in (for version D).
5. Also, I have no issues with burning/melting coilpacks as some have experienced.
Last but not least, I would like to give a big thank you to Dan (Dandymax). I sent him 3 or 4 emails asking for help/clarification on several issues before the install. Dan always got back to me within 24 hours or so and provided in-depth explanations. With his awesome write-up and his “tech support”, he made the install a breeze and trouble-free. Lastly, I found many, many mistakes in Greddy’s install manual (more on that later), but couldn’t find one in Dan’s writeup! Great job Dan!
Additional Info
The red connections you see are for the wires that get tapped. The taps are 2.5″ of wire with a female connection on the end. I crimped a male connector on each of Greddy’s bare tap wires. It did it this way so the EU can be removed quickly and easily from the system if need be.
The clear connections are the connections Greddy provided and are for the intercepted lines. It worked out really nice because Greddy would put a female connection on say Injector #1 IN and a male connection on the Injector #1 OUT. All I did was crimp on the opposite of each onto the OEM harness. If the EU is taken out of the car, the female/male Greddy connections will join together and the car is back to stock.
I plan on installing it under the seat and running the harness cable under the center console for a super clean look. When it’s done, it will look like it’s not even there……
If you have a mail-in performance-tuned ECU from Nisformance with advanced map selection features, below are the steps to activate it:
Hold COAST SET
While holding COAST SET hit the CANCEL button x number of times to select desired tune (1 through 5).
For example, to set map #2 you would hold COAST SET hit the CANCEL button 2 times. The SET indicator will flash two times to let you know you have selected map # 2.
