Neither microtech unit was able to give acceptable fuel economy even with a lot of time being put into them. Overall power output was good, just never gave good economy the way it should have on cruise.

I went to a Motec M4 V4.5 after the second microtech. The ECU was quickly setup to give the same power, but gave a little more torque at low engine speeds (from better mixture control?). The car is still giving 10 Km/litre today (around town) without any stumbles. I have had similar good experience with the Autronic SMC as well.

what problems did you have with the two microtechs ?

I have just based my order of preference on -
Ease of setup (wiring etc)
Ease of tuning of ignition and fuel maps
Amount of tuning options for fuel and ignition maps
Adaptability to a range of physical inputs including coolant temp, air temp, pressure change, knock sensing and lots more as conditions change. This can be done on individual cylinder basis on better ECU's.
Ability to run sequential injection.

There are lots more things that make my subjective ranking appear in the order i have given. These are just some of the things that immediately spring to mind.

Agreed my ranking is based on a personal preference. But it is based on facts from actual use, not just an excuse for argument or point scoring.

I currently own an Autronic SMC "auto tune", Haltech E6A, Motec M4 version 4.5.

I have owned two Microtechs. Both were troublesome. I have only worked on Wolf 3D's but find them good quality and easy to use.

Rather than Microtech (but in the same price range and much better value for money) is the Hawk system. It is sold by EFI hardware. This is a good quality cheapy that really works and has plenty of functions..

The ability to run peripheral systems is only a very small (but useful ) part of the functions of the ECU.

My 2 cents worth

I was wondering if anyone has used a link computer as this is what I have and I am going to be using it to run the efi on the A14. The link can be plug into a lag top and turned at track/home our where ever you want. Have any of you guys seen them???

i decided to spend the extra cash when i go to buy mine and get an autronic as they have a self tune program that can tune to within 2 percent accuracy on the chosen afr (so it says) but is handy up here as the lack of tuners and dynos is depressing. has anyone used this feature and does it work as good as it sounds?. still have to work out cold starts i think?

Can you expand as to why you pefer the ems in the order you have placed them??

Which ems gives the best drivability and are any of the ems in your list absolute junk??

I am trying to decide which ems to buy...my main priorities are cost, drivability / tuning ability, adaptibility to stock sensors, then ease of tuning.

I am a little suprised that u rate a Wolf ahead of a Haltech??

all this information is awsome, its realy helpfull to hear from people that have actualy had experience with some different brand ecus keep the info comming and ill continue to do some research, i will let you know what i discover / decide

antilag turns your turbo into a jet engine by retarding the timing by 40deg or so every second or third piston stroke (so the motor doesn't stall). this way combustion happens in your exhaust manifold and spins the turbo to see +ve boost at idle. really only necessary for the serious race and rally cars, where you hop off the throttle and onto the brakes and the computer keep the turbo producing boost to eliminate lag once you jump back on the throttle again.

onto the computer issue, and a computer is only as good as it's tuner. run a microtech on it's base program and it'll run like sh1t. have it tuned and it'll run better than a factory computer. install a haltech and run the 'base program' (i inverted that coz most don't come with base programs, you'll have to hunt for the settings to get it to run) and it'll run like sh1t too. have it tuned and it's the same story again.

the trouble is, most people with microtechs install it themselves and use the base program then whinge about it's flat spots and high fuel consumption. 2 hours on the dyno will sort it all out and the difference is phenomenal.

I've been using my intel pentium 4 for about a year and a half now. I know I only have dial up but once it warms up it runs like a jem!!!

Can someone please let me know if anti-lag is a load of s#*t or not? I am having a Haltech installed and have this option. Would it be worth taking?

from what i know about microtec, you have to order one for the motor you have. This means if you do an engine swap you will have to by a new computer.
autronic is very picky about the sensors and pick ups you use, but is highly tunable when its going.
haltec is a well priced mid ranged ecu as is ems and wolf.
im running an ems stinger and although i havent had it tuned on the dyno, it starts, idles when cold and cruises just like a factory efi car.
