Hi, ACE here. Started writing this while waiting for verification. Thanks!
Figured we'd throw in some tech info for those that had questions. On our site we have some details about the ECU specifically we are using (Emtron SL4) - http://www.aceperformancesystems.com/emtron-sl4/, and you can read more about Emtron on http://emtron.world from the Emtron official site that is WIP.
First, we are not in the business of knocking ANY other competing control system (stock, or aftermarket). What we do is have constructive conversations with our customers about what they are trying to achieve with their projects. In this case, some of the features and functions that were sought after made the Emtron ECU a logical choice over anything else that is out there. We quickly evaluated Jluna317 slingshot and it was clear we could improve even the simple creature comforts like idle speed control, fuel management, and just basic drivability (which most don't care about at the standalone level - we do).
As the videos above showed. We already have the platform running with nearly everything configured. We should be finalizing the calibration soon here on our Dynojet, which we plan to document in one of our blog posts like these : http://www.aceperformancesyste…e-management-integration/
Ironically (that's a joke), that vehicles "troubles" with management were totally cured with a full ECU replacement like the one we are doing here. That particular vehicle had a very fast turn around time as well even though we came from a "clean slate" just as we are with the Slingshot.
So far Jluna317s slingshot already starts easier, runs cleaner at idle, and has faster/better response regarding throttle input. The ECUs fine control of injection PW at low engine speeds already has his larger injectors characterized well enough to run a proper stoich gasoline mixture. This is with only a few minutes worth of mapping after start up. It really demonstrates the Emtron ECUs ability to properly control engines.
A "short" list of new features the ECU will support (in no particular order of importance) :
Closed loop Boost Control that can be mapped for limits, compensations for temp/gear/speed/etc (patch kits come with a flying lead for boost solenoid)
Closed loop fueling correction with short and long term learning (using wide band sensor - additional)
Closed loop individual cylinder knock detection with short and long term learning
Closed loop idle speed control using DBW (with idle ignition functions)
Speed density air/fuel mass modeling
Launch control (ECU function - separate of stability)
Traction control (ECU function - separate of stability)
Engine protection (temp, pressures, limiters, limp, etc)
Additional safety features (limiters, limps, etc)
Flex fuel capability (future, requires additional hardware)
Continuous logging (16mb of looped logging up to 500hz per channel)
Expansion function to add more sensors and outputs
Separate CAN stream for connecting to theoretically ANY other aftermarket component/data logger/dash/expansion system (user definable, not limited by brands, etc)
Fuel flow corrections based on differential fuel pressure (effective pressure, especially during boost) using the factory returnless fuel system, and the ability to upgrade to proper rising rate fuel systems and take a real fuel pressure input for active correction.
Turbo speed controls functions like Boost control, Launch Control, and even Anti-Lag
High speed Ethernet communication for the ECU (for calibration, live data, ECU log file download, and more)
This all on top of supporting the following factory functions :
All factory sensors (temps, cam, crank, position, knock, etc)
Factory Drive By Wire (with complete ability to remap sensitivity, offset target by speed/traction/boost/limp/and more - with all factory safety features)
Factory safety features such as Roll Over Protection (interface with factory sensors)
Variable valve timing control
Factory ignition coil control
Factory injection control
Factory fuel pump control
Factory fan control
Factory switch inputs for Clutch/Brake position (enables launch control functions, and more)
CAN integration features (TBD, so far we have defined nearly all the CAN PIDs, have the steering working, and more)
Everything has open config and full mapping capabiltiy. The ECU also is like a "black box" and continuously records a specific logging set
** CAN support for aftermarket systems is generally limited. It is too early to say what will or will not be supported completely. Projects at this level of modification should be more concerned about proper EFI control which is the main purpose
** Vehicles pushing higher boost pressure should have proper rising rate fuel systems to maintain effective fuel pressure
Our time is limited for forums/social media as we concentrate very hard on completing these kinds of projects, but we will do our best to monitor these threads to reply accordingly.
