i have had both and to the motec is 100 times better. 3 AEM boxes failed on me, and one left me stuck so i guess that left a bad taste in my mouth over the system. it works very well when tuned right. but i rather the motec and the software provided. to me its much easier to use than the aem. and logging is awesome. i log as much as i can, i am a information junkie i always want to know what the engine is doing. here are a couple logs.

Hey Sean

you working for one of the premier MoTeC dealers and supra shops.........

MoTeC group buy on the PDM32!!! lmao

How do you got you system setup? I mean working for Titan, I expect you to have teared your car down and basically done full spec55m/tefzel wiring with all the MoTeC options ;)

A bit of Thread Necromancy here but I thought I'd chime in with my own little story. The general wisdom of the forum members already seems to have been expressed eloquently (this thread is so much better than the equivalent threads on SF it's astonishing).

I don't have any hands on experience with either the AEM or the Motec (yet). I own an M600 but it's been sitting in a box while the car does essentially the same thing. However at one point I actually ordered an AEM mk3 PNP (I even have the invoice to show it), then cancelled my order.

The project started far enough in the past that the AEM unit was originally just not an option (it didn't exist). It was a Motec project from the start. I've always been a gadget nut, so the Motec really suited me. Then at one point when trying to revive the project the AEM was becoming very popular and the guys at SP were having a lot of success with it (Mk3 and MKIV alike).

I knew it didn't have all the expandability, flexibility, or features of the Motec, but even with all the other money I'd been putting into the project it was still hard for me to justify the cost difference, so I decided to go with the AEM.

I read page after page after page on the AEMPower EMS forums. Eventually I started what became a long thread which involved atleast one AEM Rep/Tech and many of the, uh, 'lead' forum regulars. The topic was "How is the Y axis (not RPM) on the MAF load table derived?". I'd link to it but it doesn't seem to be on their forums any more (forum reset maybe, for a long time it was the top google hit for "AEM MAF" or similar).

Even the most helpful responses included a "but you should really just run MAP anyways". While many were outright hostile and insulting. It took the form of a religion, politics, or Mac vs PC debate.

Even though several others chimed in to the thread saying they'd like to know too, I never got a complete answer to my question. I'm one who really tries to understand things, atleast at some level. I never got enough understanding to, say, make a spreadsheet that would precalc from first principles the values for the AEM's fuel table when in MAF mode. Something I can do for it's MAP mode, or either mode in the Motec.

Now, please don't take that as an insult to every member of the AEM community. There are of course many very courteous and helpful people in that community (several of them the same people I felted insulted by in the aforementioned thread). But that experience was what eventually made me reconsider and settle on the Motec.

To this day I'm very pleased with my decision.

Scranton Brothers/Ride Revolution used AEM on their 6 sec. "Celica" (2J). I know one of the members of the team before it was sold and he much approves of the AEM and uses it himself. Everywhere I looked before this thread, it seemed that AEM was the best choice.

I'm not entirely interested in doing all the little things that IJ for instance has done with the MoTeC, plus I liked the PNP aspect that makes it that much easier. I've yet to actually work with either, but because I dont really want to mess around with a completely different ignition setup--maybe COP at the most to eliminate the need for spark plug wires, but I'd rather leave the CPS alone. That plus the fact that I dont think I could get the AEM for cheaper than $1500 is sort of an indication that MoTeC probably isnt for me.

The AEM is a very capable system, and it obviously can make power (as just about any decent standalone can, or carburetors for that matter). I honestly feel it is one of the best bang for buck systems on the market (PNP really saves some $$ on install). However it has had some support issues, hardware issues and in the beginning some software issues that really cast a shadow over an otherwise really solid product. But tune it right, and it will deliver more than most people can use.

The Motec, it is in a different league altogether. Do you need all that a Motec can do? Probably not. But for some guys (Ron, 1J, figgie, etc come to mind) spec these systems out not for the difference it will make on their power/tuning as much as they just enjoy owning and working with a top shelf system. It is as much a part of the enjoyment as the car itself, adding sensors, looking at limitless amounts of data under all conditions. I myself fall into this category. With the Motec, let your imagination run a bit and chances are the system can support what you want to log, operate or try. The hardware is awesome, the software is awesome (V3 is the shiz, no other way to put it). The support Motec provides is without equal in my experience.

Okay, well I dont need any more convincing. If I see one more graph that shows all sorts of engine vital data, I'm going to freak out!

Basically, I want to just go with AEM and be happy with it than pony up money (that I wont have until I am out of school) and inevitably do things like add sensors and have ideas for them that pique my curiosity..

I come from a land down under
I :love: my M800 and the V3 software for all the reason's John has stated!

There aren't many other systems out there that can do what I need and NONE of the ones that can are cheaper.

Again as John has stated with V3 if you can imagine something there is a way to make it do it, big bonus for me is never having used v2 software I don't have any habits or preconceived ways of doing things and the V3 software allows me to do things my way!

Anyone that's followed any of my build threads knows about the massive level of support MoTeC have supplied while I've been using their gear and how happy I am with the product.

(btw John it's not one J ;) )

I've definitely followed your threads as you have obviously been breaking all sorts of new ground!

You should change your s/n to 7M. to avoid the 1J misnomer lol


He does have his nickname in CAPITAL LETTERS.

I with the two marks (One on top and the other on the bottom) no slant, unlike a 1 that has a bottom mark and the top is slanted! :)

The sad part is, I put "IJ" first (just going from memory) then thought no it must have been "1J" so I changed it. LOL Always go with your first instinct! Sorry!
