BACKGROUND

 

INFO

 

 

The

 

Infinity

 

platform

 

is

 

very

 

different

 

from

 

previous

 

generation

 

AEM

 

EMS

 

products.

  

The

 

hardware

 

(circuit

 

board

 

assembly)

 

is

 

designed

 

around

 

a

 

very

 

advanced

 

automotive

 

grade

 

microcontroller

 

(processor

 

or

 

“chip”).

  

Several

 

layers

 

of

 

software

 

reside

 

on

 

this

 

chip

 

that

 

allow

 

for

 

real

 

time

 

firmware

 

programming

 

without

 

the

 

need

 

to

 

write

 

computer

 

code.

  

This

 

technology

 

has

 

allowed

 

AEM

 

to

 

develop

 

advanced

 

control

 

models

 

never

 

before

 

used

 

on

 

other

 

AEM

 

EMS

 

products.

  

We’ve

 

listened

 

to

 

our

 

customers

 

over

 

the

 

years

 

and

 

have

 

attempted

 

to

 

simplify

 

the

 

tuning

 

process

 

by

 

employing

 

an

 

airflow

 

based

 

fuel

 

control

 

model

 

eliminating

 

many

 

of

 

the

 

lookup

 

and

 

trim

 

tables

 

from

 

previous

 

generation

 

ECUs.

  

The

 

look

 

and

 

feel

 

is

 

very

 

different

 

and

 

it

 

may

 

take

 

some

 

time

 

to

 

adjust

 

to

 

the

 

new

 

tuning

 

environment.

 

 

Our

 

new

 

tuning

 

tool,

 

InfinityTuner

 

is

 

also

 

a

 

brand

 

new

 

product

 

built

 

from

 

the

 

ground

 

up

 

to

 

interface

 

with

 

the

 

new

 

hardware.

  

It

 

features

 

a

 

modular

 

design

 

that

 

allows

 

users

 

and

 

developers

 

to

 

build

 

completely

 

customized

 

templates

 

and

 

even

 

design

 

“plug

 

in”

 

applications

 

that

 

can

 

automate

 

many

 

tuning

 

tasks.

  

Unlike

 

previous

 

AEM

 

Setup

 

Wizards

 

in

 

older

 

products

 

like

 

AEM

 

Pro

 

and

 

AEM

 

Tuner,

 

the

 

InfinityTuner

 

Setup

 

Wizard

 

“plug

 

in

 

is

 

a

 

completely

 

stand-alone

 

application

 

that

 

will

 

evolve

 

with

 

InfinityTuner.

  

It

 

is

 

much

 

more integrated

 

with

 

the

 

ECU

 

hardware

 

and

 

performs

 

complex

 

validation

 

checks

 

for

 

all
