I've been doing a bit of research into cost effectiveness of pricier ECUs like Adaptronic, Hydra, Link, Motec, etc..
From what I've gathered, those brand names where countless hours of R&D from engineers whom have more insight into engine control fundamentals to developing more sophisticated functions, like for example temp correction modeling, transient fuel, overall drivability control functions, having only one single axis injector offset and being hard to control 1000cc+ injectors and more advanced boost control and data logging.
So fair enough yeah, if you were building an all engine NA build, and an optimised tune so spark and fuel (which dramatically changes with temps) is exactly what the engine requires.
But for the average guy, who isn't chasing the ultimate HP/absolute absolute perfect drivability and tune and not willing to empty their pockets, how can he justify/weighing up between spending $500 vs $1500 ECU?

At the price point a AEM EMS 4 with harness is nearly the same cost of a MS3x with harness
When I checked its around a 100 dollar difference compared.
You do get what you pay for.
The average person will probably try to save money going with the cheaper esp thinking it can do all it says based on the features listed. I see it happen lot in person and on the internet.
Theres more to it then just perferct driveability and tune. Would you like your car\ecu to leave you stranded when one of the sensor goes bad?

Any input sensor being used by the ecu to control the engine.
Yes but that requires mean to have to the laptop on me at all times. What if I don't have it on me when some sensor takes a ****?
Not as simple as just disconnecting the maf\map and turning the car on and driving off.
You mean you dont also do a backup tps based OH **** tune?

I see Tech is back to trollin', and giving himself props for every goddamn thing he posts.
Considering that I've had the car running on a megasquirt with every sensor either miscalibrated, not working or unplugged at some point or another but for the CAS/tach stuff, I think you don't know what you are talking about.
/Equally, I think I should probably make less mistakes on the sensors.

Disconect the o2 sensor while driving in closed loop,
Have your IAT become disconnected and watch the bitch over fuel by the default ideal gas law that is hardcoded, etc
I also don't give myself props for anything I post

This started as a troll thread and it's trying to end as a troll thread.
Explain to me how the ECU choice matters when running speed density on any car?
One time my car died and had to be flat-bedded. A sensor died. It was the ******* OEM cam sensor.

Toyota Pickup crank sensor failed a couple of years ago - truck stopped running completely in busy four lane street and had to call a tow truck. WTF are you talking about? Troll is trolling.
And on to "histograms", TS VEAL does tell you how many times the cell has been touched and how much weighting has occurred with the same little colored chart if you click on the correct tab to view it. The boxes are labeled "cell change" and "cell weighting" and are under the "status" tab in VEAL. It looks very similar to the example posted on the previous page. And you can have every parameter line traced (like an EKG at the hospital) with max and min values listed.

You get what you pay for, if I were to do it again I wouldn't even touched a megashit after dealing with mine and others. Sure it can run an engine but its missing many things to run an engine even close to OEM setup.

When I checked its around a 100 dollar difference compared.

Just learned the word wrong?
There are features of MS that are poorly implemented, implemented wrong or touted as a feature when they shouldn't be.
AEM ems 4 with small harness
AEM SERIES 2 EMS-4 UNIVERSAL PROGRAMMABLE ENGINE MANAGEMENT SYSTEM 30-6905 | eBay
759$ total for AEM EMS4 with small harness
MS3x
MegaSquirt-III EMS System with MS3X Expansion V3.57 - Assembled, Brushed Case DIYAutoTune.com
640$
required harnesses
8' MegaSquirt Electronic Fuel Injection Wiring Harness (MS1 / MS2 / MS3 Ready DIYAutoTune.com
8' MegaSquirt Wiring Harness for MS3X DIYAutoTune.com
779$ total for ms3x assembled with both required harnesses
*noted I used both the small 8" harnessed for the ms3/x
I guess the price difference between the two has shrunk now.
