AEM
BOOST CONTROL!!!
this is BY FAR the biggest glaring omission from the FAST... i see 6 and 7 second turbo cars using this ECU but they have no way of controlling boost with it... on a street car, a boost vs. road speed (or boost vs. tps) table is invaluable...
the AEM was mentioned... let me try to say this plainly: the AEM will replace all other ecu's if the other companies do not step up with *considerably* more features/dollar... i'm sure that statement will catch a lot of flack, but take a look at what i got for $1300:
the obvious, complete fuel and spark control, accel/decel fueling, warm up enrichment, idle control, etc...
17 load "rows" and 21 rpm "columns", all of which are adjustable to be at whatever values you want (ie. they don't have to be evenly spread out)... this is a big win for running 18psi for example... no need to have the wasted rows of a FAST 3-bar setup, nor the lack of range of the 2-bar setup...
wastegate control (based on road speed or TPS) , 10 injector drivers, 5 coil drivers (up to 10 cylinder in wasted spark), 4 High side outputs (+12V), 12 Low side outputs (ground)... all are configurable to activate at a specified load, coolant temp, rpm, and tps %... there are also extra idle air (pwm) outputs and fuel pump outputs, as well as a completely user-defined PW output with its own load vs. rpm table... this is often used for alcohol/water injection or similar...
input wise, you can hook up multiple speed sensors, EGTs, temp sensors, 2 O2 sensors, 2 knock sensors, etc... and you can program a response to these devices... you can modify fuel and timing in resonse to EGT input, knock input, coolant temp, air temp, etc...
all inputs are programmable and can be used with any type of sensor... ie. you aren't tied to having a GM coolant temp sensor, you simply enter a table of X volts equals Y degrees and away you go... same thing with the o2 sensor, MAP sensor, TPS, etc... you can use a DIY wideband, an FJO, a horriba, an NTK, you name it...
automapping - drive around with the wideband o2 and have it autoprogram your VE table...
automatic transmission control...
on board memory for logging without the laptop... or if you use your PC, you can build a graphical dashboard to display input from the ECU in any way you like (analog looking gauges, bar graphs, plain numbers, etc.)... the logging utility allows you to apply math formulas to the data if you like, so you could do things like compute HP based on the rate of acceleration (since the ECU understands road speed)...
a/c control (along with a programmable idle jack to prevent stalling), nitrous control (with extra fuel and timing maps), staged injection (two sets of injectors, primary and secondary), two rev limiters (programmable to pull fuel, spark or both), etc.
mass air or speed density...
firmware upgrades performed by the user through the software...
that's just everything i can think of off the top of my head... this thing will do A LOT...
oh, and did i mention that it simply plugged in to my factory wiring harness? not a single wire needed to be cut... unplug the factory ECU and plug this one in instead... 10 minute install...
i've been very pleased with the results of my FAST on my camaro... but when i recently needed to buy an ECU for another project car i couldn't pass up the AEM for the *price*... in the past, i knew a system like the Motec had tons of flexibility, but for $5000+ i wasn't interested...
hopefully, Craig and Lance don't see this as an attack, but rather a heads-up... i didn't build the AEM, i'm not the competition... but somebody would have to be crazy not to consider such a flexible, feature-rich system at that kind of price point...
