When to look for an aftermarket ECU?
Factory ECUs do a great job of managing the engine parameters in an OEM environment. However, when you start to exceed the limitations of the factory ECU you should look into the aftermarket. You can scale a tune to stay inside of these standalone ECU parameters but it will ultimately lose resolution in the long run.

Where does the ECU get power from?
The base of the transistor is a keyed 12 volt source. The collector is connected to the one end of the ECU power relay coil, with the other end being connected to +12V. When the key is turned on the transistor conducts, energizing the relay and supplying power to the ECU.

Why are ECUs adjustable?
Infinitely adjustable. Because the ECU is made to be tuned and modified, most companies in this market know that tuners what the ability to add, control, change things on the fly. This makes these ECU’s very versatile and able to handle all kinds of parameters and situations. 2.
Do signal wires have to be modified before or after the ECU?
Things can really get complicated when you realize that some signal wires have to be intercepted and modified before the ECU and some after the ECU. And some cars will work better using one method than the other. Figuring out the best set-up for your particular vehicle can be a never ending process.
Does the temp gauge work when changing the ECU?
There are times where the temp gauge or tachometer doesn’t work when changing the ECU. Also the gauges that do work, will most likely have to have their parameters set up in the ECU.
Can an ECU be tuned?

1. What problem are you trying to solve?
Do you want to produce more power? Are you switching from carburetors to fuel injection? Adding or augmenting forced induction? Compensating for different fuels or blends? Merely trying to get a handle on various engine parameters to make better decisions?
2. How will you control your new ECU?
The ability to minutely alter every engine setting is both the advantage and the burden of aftermarket ECUs. Still, if you’re not comfortable handling some basic tuning functions, that shouldn’t be a dealbreaker.
3. How ready is your engine for an ECU upgrade?
To control your engine functions, the ECU needs to monitor a slew of parameters from the powerplant. Crankshaft position, exhaust mixture, fuel flow, various pressures and temperatures, rates of rotation and even acoustic monitoring for preignition all factor into the final engine control scenario.
4. How will you monitor your engine in the car?
You still need to keep an eye on all the important operating parameters of your engine, and this is where you have a few choices.
5. What else do you want your ECU to do?
The ECU functions simply: It has inputs that are looking for a range of resistances or voltages as well as outputs that send signals of specific voltages or waveforms. These inputs and outputs are typically definable within the software interface of the system.
