Ahh, I was unaware they made all the changes revisions and updates. That makes more sense why people like Dem and lassi are having much better experience with their units.

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?
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.
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?

you mean the OEM cam and crank sensors or the $30 MAP sensor?

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.

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.

rip out your load sensor throw it in the ditch and try to start your car and keep it running and driving around properly. 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

Oh, you can /start/ it and even drive it to certain parameters of drive.

...wut? This one is just funny Tech. You can drive fine without an O2 sensor in closed loop. It'll just pull/add (depending on O2 configuration) fuel of X% maximum of your fuel table, so you may run a bit rich or lean.

Oh, I've driven no problem with a disconnected IAT sensor.

Stranded means something else entirely then what you think it means apparently.

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.

Then you suck at using your ecu, you can set pretty much all of them to automatically use backup maps if something faults out.

Um duh, didn't you know you could spend silly amounts of money and get an ecu that uses the knock sensor to detect the firing pulses? (Apprilla does something similar).

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.

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&#39 MegaSquirt Electronic Fuel Injection Wiring Harness (MS1 / MS2 / MS3 Ready DIYAutoTune.com
8&#39 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.

You dont want to use that harness for the MS, you want to make it work with a factory connector. That D-sub connecter doesnt have a rating for cross talk the last time I checked, much less a good rating.

So, have you actually tested the AEM to check all the features work correctly and as advertised?
