different types of ecu
 

can someone explain the differences between the autronic, ecutek, motec, verso and microtech ecu? any info will be helpful

Ummm - search otherwise ... Rossco where are you?

lol he is an infomation whore

search...or ask your preferred tuner which ECU they prefer to tune.

i have had a search around, but i dont know anything about the different ecu systems. i was just hoping for someone with a bit of knowledge to break it down and explain it. i was told autronic is good but at around $3200 im wondering if there is something for less than that, that will do the same job?

3200?? hah! there was a thread on here where they were selling for 1700
ASG are power fc specialists and reflash verso
MMS are autronics specialists and reflash ecutek
Motecs are for all out racing and havent seen many microtech ecus in wrx's.
With GC8 your cheapest option would be power fc, they are direct plug and play. Although they dont retard timing ad they dont have options such as antilag or rotational idle.
You get what you pay for.

thanks for the input, i was told 3200 by MMS but that may have been tune included im not 100% sure.

sounds like tune+ wiring it up included

yeh i would say you are probably right

Verso and EcuTek are not hardware, they are simply cracking the code and re-writing the software that is inside the existing ECU that the car already has. (where possible)
This has advantages and disadvantages.
All the others you mentioned are replacement engine control units that can be reprogrammed to your desired settings using the software that comes with the unit.
MoTeC and Autronic are the high end of the market with advanced features. Power FC, Microtec, Link etc are less expensive and offer varying degrees of features.

here you go

Thanks for that mate. What would you recommend? I'm looking for a few peoples opinions on what they prefer

try and find second hand autronics it would be cheaper than new, i brought my smc plug n play off a member for $1000 then install and tune would be around $500-$700. i did look at vilpec ecu but this option was cheaper and autronic ecu has better software, faster tuning, few different options rotational,anti lag, launch control.

Nah, I'm just a whore............. :D

Ask yourself what you NEED for a street car.

You don't need:
Anti lag
Launch control
Rotational idle

UNLESS you are building a monster HP engine / track car.

I'm a big fan of Power Fc's for Gc8's, they retain all the factory ecu's functions (a/c idle up, power steering load idle up etc) but add a wide range of tune-ability.

They have a hand controller to monitor temperature, boost, knock etc live, without the need for a laptop or $$$ proprietary dashboard.

They are easy to install (plug & play) & a tune is about $400-500.

Stock wrx with an exhaust & 1.2 bar will make about 190 -210 hp atw on a safe tune.

You can find them popping up for under $1k used.

from your avatar, i'm assuming you got a classic shape rex
your choices are limited to piggyback or full replacement ecus

need to decide what you want with the rex
power fc maybe best bang for the buck

Equivalent year STi computer = best bang for buck.

I did a 98 recently, fitted 440's, 90mm AFM, STi version ECU, VF34 and a 3" exhaust. Driveability was superb, AFR's were safe, no ping, went like f**k!

is that the JDM STi ECU?
or ADM?

Doug what would a V6 oem ecu go for?

Yeah Joe, the car was an Aussie 98, so no local STi version available. I swapped the wiring over to suit a JDM ECU.

Ross, I reckon $200 - $300 for a STI computer, but I think AUS versions have an inbuilt immobilizer that makes them difficult if not impossible to use in a different car.

The reason I wanted to try using the stock STi computer is that V3/4 STi's go so damn well from factory. I pulled a 12.7 @ 102 out of a $5000 bunky with only a catback exhaust. They start hot or cold better than 99% of PFC equipped cars, no flatspots, no blackened rear bumper, no dyno time etc.

of course, forgot we didn't get sti for 98
that's pretty good. it is tuned for a higher ron
but the tune probably gave it plenty of margin to run the lower oz ron

damn, i actually sold a few old STi ECus for $100 and some at $50

There's no immobilizer on the Aussie V6 ecu's (hence the early thin headed liberty type ignition key they have), all other aus 99-00 Gc's had transponder chipped keys.

You do need to do the cam & crank sensor wire swap to run the Sti ecu in a wrx though (same as when fitting a Pfc to a Wrx).

My 1% PFC cold / hot start is the same as my stock ecu was. :)

would a v3/4 sti ra computer be compatable or different altogether?

im hoping to get 200kw from my gc8, its stock but im going to mod it all in one hit, 3" TBE, vf35, equal length headers, processwest TMIC, processwest CAI, fuel pump and injectors.

just in relation to the sti ecu going into a wrx, i searched and people were saying that the sti has an air temp sensor

would this affect car in anyway? flashing warning lights? i think someone said that the car would overheat or something like that and cause motor failure

thanks in advance

[QUOTE=red dragon2002;501679]......... the car would overheat or something like that and cause motor failure [/QUOTE]

everything causes motor failure if you believe what you read on the internet.

"I used upper engine cleaner now I popped a big end"
"I vacuumed my car now it's got a headgasket leak"
......etc.

Air temp sensor is probably desirable if you can be bothered running the extra wires, lots of pepole ignore it and they work fine. No check light.

great, that's good to know

thanks for the information

No bug love now I get no Doug love.

I see no sense in going on :D

may i add, thats applicable to stock ecu scenarios only.

not using air-temp sensors on a MAP based ecu (autronic/motec/link) is plain crazy.

on the v5/6 ecu's the temp sensor is used to pull timing if the inlet (airbox intake) air temp exceeds 55 degrees, below this temp it does nothing.

The power fc allows you to map it's output to reduce both boost and timing, I've set mine to pull the boost back to 1.5 bar & pull 3 degrees of timing > = 50 degrees c to supress det.
