THE BENEFITS OF CONTROLLING FORD'S TiVCT WITH INFINITY
The Infinity ECU was the first programmable EFI system to deliver programmable variable cam timing (VCT) for the Ford Coyote TiVCT system. By controlling the Coyote's VCT on all four camshafts, tuners are able to create more peak power over no VCT or when tuning only intake variable cam tuning, and significantly more mid-range. The following dyno plots were performed on a stock Ford Coyote engine, on the engine dyno at CPR in Gardena, CA, where tuning the intake and exhaust VCT netted a peak gain of 42.3 HP @ 6500 RPM and a mid-range gain of 109.3 Horsepower @ 3900 RPM. The Coyote's torque gains are even more pronounced, showing a peak gain of 85.8 lbs/ft at 4,400 RPM, with the largest torque gain of 149.9 lbs/ft occurring at 3,700 RPM.
The engine tested was a 100% bone stock take out from a Mustang GT. The power and torque data shown is representative of optimized cam timing and not just sending the cams to their max advance/retard positions. The purpose of the testing we did was to show the changes in torque/power output based purely on optimizing airflow by varying both the intake and exhaust cams while maintaining the same AFRs and using the same ignition timing. We felt this was prudent as some competitor systems that also have EMS solutions for the Coyote aren’t able to do variable cam control and have attempted to downplay its real benefits. We feel these dyno results pretty clearly show how beneficial the Coyote variable cam system is.
As is shown, we first ran the engine with both the intake and exhaust cams at their resting positions (fully retarded for intake and fully advanced for exhaust). Fueling was adjusted to reach target AFR and a base timing value was established. We then started tuning the intake cams only and through a series of pulls, found optimized cam advance values that netted the best increases in torque/power output. We repeated this same process for the exhaust cams while also moving the intake cams. In each iteration, fueling was adjusted to account for increases in airflow in order to reach our target AFR. This is the typical process for variable cam tuning on any engine.
We ourselves were surprised by the results – especially the gains made by retarding the exhaust cams. We’ve done a lot of variable cam motors in the past and are used to seeing sizeable gains by advancing the intake cams. In most cases, however, moving the exhaust cams has usually netted a decrease in torque output as there is fuel/air charge dilution by the exhaust gases. It’s common that variable exhaust cams are used much like EGR for emissions purposes by the OEMs so it was surprising when the Coyote made huge gains by varying the exhaust cams. It was very evident to us that varying both sets of cams was vital in getting the Coyote to its full power potential.
AEM Ford 5.0L Coyote Plug & Play Adapter Harness (AEM PN 30-3812) for its Infinity programmable standalone ECU is for racing engines that are using the Ford Racing Controls Pack (FRCP). AEM’s Coyote Plug & Play harness provides racers and engine builders who already have or plan to purchase an FRCP with the ability to quickly install the Infinity ECU on a Coyote engine (around 30 minutes).
A Complete Standalone ECU for the Ford 5.0L Coyote Engine The Infinity ECU combines with the Coyote Plug & Play adapter harness to retain full control of the engine’s TI-VCT variable cam timing control and Drive-by-Wire (DBW) system. The Infinity ECU is to our knowledge, the first standalone programmable ECU to deliver full control of all four of the Coyote’s variable valve camshafts and deliver programmable control of the Coyote’s drive-by-wire system. This capability provides tuners with the ability to take full advantage of the engine’s mid-range power potential through the adjustment of all four camshafts anywhere in the RPM range, and create two drive-by-wire profiles for rain maps, pit lane limits and more. The Infinity Coyote adapter harness is compatible with factory sensors and injectors for simplified startup using the supplied base calibration on most applications (may vary based on engine set up and forced induction). AEM’s adapter harness also eliminates the restrictive factory mass airflow sensor (MAF) and airbox, making it an ideal harness solution for forced induction applications. Other key racing features include multiple boost control strategies, programmable nitrous control, on-the-fly map switching, programmable four-wheel speed traction control, launch control, flex-fuel, and multi-fuel capability. It utilizes airflow (VE) based tuning, has up to 64GB data logging capacity and can transfer data at up to 480Mb/second. Its enclosure is sealed and suitable for engine bay mounting.

AIRFLOW MODEL BASED CALCULATIONS
Infinity’s airflow model-based systems greatly reduce the amount of time it takes to set up and tune an engine by eliminating many of the lookup and trim tables (correction tables) necessary in previous generation ECUs. The Infinity’s airflow based, or volumetric efficiency (VE) based models calculate an engine’s requirements in real-time based on an advanced algorithm that has various modes for calculating air flow. Once the user inputs an engine’s basic parameters (displacement, cylinders, ignition type, and firing order) and methods of calculation for airflow and ignition they can begin setting the engine’s VE table in the software.
InfinityTuner USER INTERFACE SOFTWARE
InfinityTuner is optimized for speed and performance. The software has the power to control a multitude of features found in today’s modern racecars, and features an advanced tuning Wizard to reduce set up time. An ECU Setup Wizard takes complex calibration setup work and simplifies it through a smart interface that features tabs for quick set up of vital engine functions. Each tab includes a description of the function.
InfinityTuner software is highly flexible. It allows you to choose from multiple strategies for boost control, idle control, traction control, charge air temp blend, launch control and more.
All controls in the Infinity ECU are synched to logged data which allows users to edit calibration data during log playback to minimize tuning time. AEMdata, AEM’s advanced data logging analysis software is also included for reviewing data logs.

The Infinity ECU uses a coolant temp based idle control model. It includes an RPM vs. Engine Speed Rate idle decel feature that provides accurate control of the IAC and allows for adjustment of engine braking. The Infinity’s idle TPS offset provides smoother low idle operation when necessary, like driving in the pits or return lane following a pass.
MULTIPLE BOOST CONTROL STRATEGIES
Choose from time, gear, vehicle speed, switch-based or other boost control strategies. The Infinity’s boost control includes two 2D base duty tables and two 2D boost target tables. The second tables can be used as a trim, and users can choose from multiple strategies including IAT, MAP, Baro (kpa), throttle %, flex fuel content, boost target and more. Please visit our Forum for an in-depth review of the Infinity’s boost control capabilities.
The Infinity’s software allows you to run a single-stage wet or dry nitrous set up (four-stage available soon). This feature includes nitrous timing delay to account for nitrous bleed out and can be set up for water/methanol injection tuning. Four stage nitrous will be upgraded for free for existing Infinity users when it becomes available.
VARIABLE VALVE CAM CONTROL
Set base duty, limit and VVC cam target for up to four cams through the InfinityTuner Wizard. Users are able to achieve a VVC cam target by setting Cam 1 base timing and base duty cycle % in a 2D table, and the software features a 1D base duty % table that controls the base duty cycle for the VVC output, which is tunable based on the VVC target.
The Infinity includes up to four separate ignition maps, four separate Lambda maps and two separate VE maps with independent values. Using AEM’s 12 Position Trim Pot, this powerful feature delivers many valuable tuning options including:
