The car drives in the same manner it just has better power delivery, comes in sooner and smoother and harder if that makes sense.

Don't forget subaru will not map each car they have a generic map they throw on each model and leave the sensor handle things like ign advance.

So it is possible to improve on what manufacturers supply, otherwise garages would have a hard time selling their wares.

Full on..........all i wanted was peoples opinions on the said product,in my opinion the factory maf is a weak point on my car and as appealing the apexi,ecutek etc were each still use the maf.
As stated above the factory ecu is generic and although good enough at time of sale, each engine wears differently and an individual map of any ecu of a good mapper can only be better for that particular car

I think that is a very concise and accurate summation and the fact the factory map is generic is a good point.
The MAF sensor M/Y 99 and 00 is a clear weak spot on the Subaru but other model years are more resilliant.

Ginge !

iTrader: (1)

but the generic map is still a very very well written map, they dont write a map for one car and go " yeah thats safe "

they test engines on dynos over months even years sometimes before we get to hear about them

weak points of engines are not on discussion here,,, as due to the volume of simtec or any other aftermarket ecu and the expected life time it will be hard to find a comon fault with them as quick as it would a factory made car

Granted,but in my particular case the maf is a contributing factor for me going for an aftermarket ecu ,I know that manufacturers spend a lot of time and money on developng the electronics ,but it is still using the maf and has to cover a wide variety of situations which may arise in a cars life.
To be honest if you feel happer using the factory map/ecu and havn't got any mods then all is good ,but i feel happier looing the maf and having a different ecu which will cater for my mods and at the very least give me a engine health check by a competant mapper who is familiar with the ecu

Tell that to the owners of classics back in 2000 when their cars had the AE802 ecu. The difference in terms of how the car performed were very noticeable over the earlier AE800 and AE 801 ecu's, hence there was a flourishing market for everyone wanting the earlier ecu's to replace the AE802.
Not long after that Ecutek was born and took over..

I have a simtek in my V5 limited. It starts 1st time everytime and the idle hot or cold is perfect. I had it fitted to replace the MAF and for me it is brilliant. I didn't bother with the extras as I couldn't see the point.

well if you havnt got the simtek yet...you should get it.
i have it in my v5 type r over 6 months now with a (pat map)
and have no problems with it.
the 1st thing i noticed was how smooth it was up through the revs.
i got the asl and lc to go with it,

here you go......

Ive a simtek in my RA it was already fitted when i bought it. The only downside is it hunts a little on idle and turning on the ignition and the waiting 20seconds before you start the car.

RA Dunk

same as mine, the idle is a little rough and the fuel pump takes a while to prime

antilag is just a gimmick that sounds nice but thats the only benefit of it unless you have a steady supply of turbos and can set it set up "properly", havent tried launch control yet as im not really into hard launches or 1/4 mile stuff only track days where i do rolling starts from the pit lanes

If I understand correctly, the Simtek can support 2 maps which is very useful - you could have one economy focused or for low grade fuel as well as your normal map.

That's a big plus point for me.

RA Dunk

thats what swung it for me TBH, one map for normal fuel another map on scottimax for trackwork

Mines mapped for 97ron and Vpower.... Yeh the antilag is a bit of a gimmick but sounds sweet and dont think ill ever launch it hard enough to warrant using the L/control.

The "turning on ignition" and for 20seconds before you start the car really does get on my nerves but i suppose its a negative point i can live with.

Sorry, dumb question - why do you have to wait 20 seconds before you start the car?

WRX_Dazza

i've had mine for a good few months now.

cant complain, had a few issues with cold starting, but that was soon fixed.

other than that, getting great boost (had to have the turbo ported to correct boost creep.)

had mine fitted and mapped by Zak at mocom racing and i would highly recommend speaking to him, if you want to go down this route.

anti lag is a must down the dark country lanes and really brings out the rally experience lol
remember the grin you had when yo first got the flat four rumble, well multiply that by 10, when you come off power anti-lagging !!! -

good luck whatever route you choose.!!

Its what i was told when i bought the car and what the previous owner was told when he had the ECU fitted. If its not left for about 20seconds with the ignition switched on it throws a CEL light, maybe someone in the know can explain why this is. Ive tried to find out the reason why but cant find any info.

RA Dunk

never heard of this, it does take a while for the fuel pump to prime but nothing like 20 seconds with mine?

harvey

iTrader: (48)

20 secs sounds like a long time for the pump to prime the system.
When you switch on you should here the pump priming. As soon as it stops priming, turn the key to start. It is normally around or less than 5 secs on my two cars fitted with the Simtek.

If you do buy the simtek ecu, make sure you get it from the mapper you are going to use all the time.

Otherwise you have to buy the software for an extra £115, just so you can take it to a different mapper.

Gimmicky...hell yes they are.....it's all dependant on what your plans are with your build......

It'll be going on mine sometime soon...for fun around the twisties & if i do get to compete in my Scoob it'll all add to the momentum of the car over a measured distance....

Antil-lag...what fun.....in the right place.....around Mcdonalds..No No your asking for trouble.

Simtek or another i'm not sure yet......

Andy.F

No need to wait on the pump priming guys, just jump in, turn the key right round and it starts.

Andy

Well i can but she gets grumpy if i try doing that, i just wait for her to prime then she's happy.

Possibly due to the larger injectors needing to be filled up who knows.....

I stumbled upon this post by accident.
I was so intrigued by the wording above that I ended up having to read what you were on about.

For example She gets grumpy.

For what its worth, my wife gets grumpy if I just "jump in" before priming her

Now mine's been mapped properly it does exactly as Andy says. Starts and idles hot or cold immediately at the first turn of the key.

A very different story from when it was first mapped but that's for another time.

Simtek seems a great ecu to me.

I have found the dual map option invaluable.
So depending on your application this could be a deciding factor.
For me it's 1 map for track/race and one for road.

Just doing some ECU mapping research. What software is used when mapping a Simtek ECU, is it available if you buy a stand alone Simtek ECU?

how do you switch between the 2 maps.

With a switch (honestly)

My 2nd map is for crappy unleaded fuel. Still pulls like a train
