Acura Legend Comptech Engine Management Piggyback (and universal) This would probably be way better than the stupid check valve that I have. Professional grade at least. Cool, none the less.

Comptech ESM Engine Management Piggyback

Comptech Electronic Signal Modifiers are adjustable switches commonly used to keep the ECU from seeing a boost signal from the MAP Sensor when you are adding a turbo or supercharger to a car that didn't come that way. Comptech ESM's can be used on any car or sensor up to 3.4 volts. They have an easy four (4) wire hookup, and come preset for Honda/Acura MAP voltage signal. But Comptech ESM's are easily adjusted to fit the needs of other cars (universal fit).

Powerhouse MAP ECU Engine Management Piggyback



For anyone who has ever installed an aftermarket turbocharger system on a naturally aspirated car, upgraded the turbos and/or fuel system on a turbocharged car, or wanted to remove the restrictive MAF meter on any car, the MAP ECU (Manifold Absolute Pressure Electronic Control Unit) is for you! This piggy-back system is similar in function and design to the super-popular HKS VPC (now discontinued) however, the MAP ECU takes it one step further by allowing end-user programmability via Windows-based software. The purpose of the MAP ECU is to mimic the voltage or frequency output patterns of the factory Mass Air Flow(hotwire) or Karman-Vortex meter but uses RPM and Manifold Pressure to make its calculations rather than airflow. Basic setup takes only a few minutes, and allows the user to custom tailor the MAP ECU to work with almost any automotive system on the planet. The user can set the number of cylinders (1-16), type of air metering system utilized (Karman-Vortex or Hotwire), throttle position hi/low voltage range, throttle or MAP based enrichment, and the type of oxygen sensor utilized (OEM or wideband).

The powerful yet easy-to-use-software installs in any Windows operating system, and communicates with the MAP ECU from your laptop via a serial cable (supplied). The MAP ECU software allows the user to monitor MAP ECU inputs and outputs in real-time, make real-time adjustments to MAP ECU tables and parameters, manipulate data in 2D and 3D formats, and log critical ECU data for evaluation at a later time. Once the mapping is completed, the laptop can be removed and the unit stores the data in permanent memory. Of course, with the laptop connected you will find a wealth of information available to you while the vehicle is running. The MAP ECU operates as a piggy-back control unit, allowing the user to maintain factory ECU control of the primary functions, but modify the fuel mapping parameters to suit larger fuel injectors, different camshafts, upgraded turbochargers, and forced induction conversions. What this means to the novice tuner is no more lost sleep trying to get the car to start or idle correctly with a full stand-alone engine management system. Most importantly, the MAP ECU does what other similar units on the market cannot do: convert the factory Mass Air Flow (MAF) or Karman-Vortex (VKF) signal into a speed-density (or manifold pressure) based signal, allowing the user to completely remove the factory air metering system. This adjustability means that the MAP ECU has coverage for over 90% of current production cars on the road today. One of the most powerful features of the MAP ECU is its ability to self-learn from factory MAF or Karman-Vortex meters. This feature means you can build a base fuel map using factory components then install aftermarket components and adjust the mapping to suit your needs. This makes the MAP ECU perfect for OBDII-equipped cars, since you can build a base map using the OEM sensors, and then remove the sensors so that no fault codes are tripped in the process. The MAP ECU basically becomes invisible to the factory ECU, but lets you remove the air meter and have all the advantages of an adjustable fuel curve by modifying the airflow input.

Some other features of the MAP ECU include a TPS input for throttle-based fuel enrichment, and dual pressure switch circuits to activate auxiliary devices according to manifold pressure. The pressure switch circuits are perfect for activating additional fuel pumps, NOS systems, or intercooler spray bar systems. A basic installation of the MAP ECU requires connection to only four wires at the factory ECU (+12v Ignition, Ground, RPM input, and Air Flow Meter input to the ECU) making installation easy for even the inexperienced installer. The MAP ECU features a built-in -12 psi to +30 psi pressure sensor with a customizable pressure scale and a 0-8000 RPM engine speed scale. The basic kit includes the MAP ECU, an un-terminated 3 universal wiring harness, air temperature sensor, serial cable, installation and tuning manual, and MAP ECU software on CD ROM.

MAP ECU Version 2.2 incorporates a wealth of upgrades over the previous Version 2.1 firmware/software package. New Dashboard screen provides the tuner with more information than previously available, and includes a miniature scaled version of the MAP ECU Table showing the current load point. New ECU functions include complete NOS system control with NOS solenoid activation by RPM and throttle position, and zoned TPS and MAP enrichment by throttle position and/or RPM. We have also incorporated a password function to protect the MAP ECU from prying eyes for those who wish to set it and forget it . With all these functions now built-in the unit, it s hard to find a comparison with similar so-called fuel controllers. Constant improvement is what makes the MAP ECU a hands down winner!

Yes, That is the price!!! I thought all of them were 2k+
I am going to go balls to the wall! Look to see 500+WHP in the next year or so.

I'm using Comptech's ESM on my boosted NSX. Was running a Jackson Racing unit, but it quit on me causing the car to go into limp whenever the MAP sensor saw voltage higher than it liked (JR unit wasn't capping). No fun.

Replaced it with a Comptech unit especially because it is adjustable. Boosting happily since.

The MAP ECU sounds like it is intended mainly to convert MAF sensor setups to MAP. I don't know if it would be worth it on a Legend since we already use a MAP setup. You could probably do the same thing with an AFC on a car that came from the factory with a MAP setup. I say go with a AEM ecu, much less than $2k.

The ESM is a good unit, I've used one before.

I will try the Comptec first just because I already have the Apexi stuff, but I am really curious about how the powerhouse unit works. I love stuff that uses windows....it is spiffy :****:

Anyhow, What are the difference between the AEM and the powerhouse?
Can you control timing with teh AEM? What about price?
Sorry, just so excited!

You can control pretty much every aspect of it with the AEM. The NSX AEM is 98% plug and play for the Legend. Check out the thread on this page by Legend4Life, he has the AEM on his car.

Sorry.
The AEM seems difficult to install.
Was it?
Thanks, Kyle
The tuning of the AEM would be the difficult part if you were attempting it for the first time. The NSX AEM ecu will plug directly into our harness. Or you can get the generic AEM ecu and wire it up. Either way, lots of time will need to be spent on tuning to get it right. If you really want to be to tune your car, this would be one of the best ways. Try emailing Legend4Life about it, his GS is running off the AEM now.

The MAP ECU is NOT FEASIBLE on the Legend. It's a MAP car to begin with. The simple purpose of the MAP ECU is to convert a raw pressure signal into a MAF signal (0-5v) in order for a stock (MAF-based) ECU to correctly read input and output, and correctly clamp the outgoing signal. This will not work on your cars.
