ECU differences
My car (06 spec c) has been mapped a few times now with each upgrade,
Would I benefit going for a SIMTEK ? not really bothered about ALS or launch control !
over that would a SOLARIS be even better ?
do these ECU'S offer a more detailed map allowing to produce more power ?
if anyone could give me a good overview ?

Should have mentioned this before, Car is currently having the engine built 2.1 CBD, omega pistons etc so should be hitting around 500 - 550 mark when ran in. before the build the car was running 400 bhp on standard internals .

You have selected options of the two top runners imho.
The SimTek is very very good and will do a fantastic job, the Syvecs (Solaris) is the best. Your budget will have an influence, especially if you don't want antilag and launch control, we are spoilt for choice now, go back a very short time and the previous options were imho a lot more agricultural in there operation and software to map them.
Yes you will get more power than on the standard ecu for a number of reasons, the processors are faster, the maps have higher definitions and changes are done live and in an instant so when mapping the mapper can try numberous options in a very quick time rather than a long and drawn out process with the standard ecu with a high powered car. Don't get my wrong the standard ecu is a fantastic bit of kit for a mildly modded car but left behind when you get to this kind of power level / mod level.
Also sometimes find the standard ecu at 450+ will falsely pick up forged piston noise as det and retard timing and therefore be inconsistent and pulling timing and therefore power. This can be reduced by dampenning down the standard ecu sensitivety which then kind of defeats the object.
The SimTek's knock control has not been completed yet but should be available as an upgrade when it is etc. Although the flashing of the engine light does work very well as a det warning.
The Syvecs knock control works very well and also can be setup to switch the cel light if it has removed more timing due to detecting det than a specified threshold, allowing you to know it has. Also has the datalogging which you can download yourself with the software freely available on the website.
For most the 2 maps on the simtek are plenty, there is the possibility of an alteration to allow more.
The syvecs can have up to 8 map combinations on a rotary switch.. say low boost, high boost, crap fuel, good fuel etc .. or just two on a normal switch if you want.

for example I have fed the oil pressure and oil temp into my ecu for monitoring purposes and setup engine trips.. if the oil pressure drops below a set threshold it cuts the engine, if the oil temp exceeds a set threshold it goes into limp mode whcih is currently 4000rpm etc.. along with water temp trip at 105C to limp mode.
Its nice to go out on track and just drive and know that if something happens I will be alerted to it rather than having to watch gauges etc.. I still have the gauges fitted but don't have to watch them if I am ON IT and to plug the laptop in after a session and read back the logs.. these features are fantastic but may never be used by lots of customers.

Its a complicated and also political subject.. ie. some tuners only supply certain products etc.. so I'll just touch the surface of the subject.

simon,
do you not find it find it quite nerve racking
that if your going round the track (on a straight at over a ton)
and then suddenly the engine cuts out
would this not cause confusion (i.e is there something wrong with my car or was it the ecu that did it)
cheers

And no it doesn't worry me, primarily because if it happens I'll know about it due to the fact I'll have had a dash full of warning lights (inc a message telling me what input is out of parameter) before the actual shutdown, so will probably already have lifted off, and even if I haven't, the message display will tell me straight away why it's happened.
would this not cause confusion (i.e is there something wrong with my car or was it the ecu that did it)
I'd much rather have the ECU do it electively than wait until a very unpleasant noise under the bonnet, or a load of smoke out the back, or whatever, tells me I need to switch off.

yes
currently have few customers in the late 400s on ecutek... I think they may possible make 500+ on after market ecus as spend so long sorting issues with standard ecu.
There is a map based rom file available.. however you are still fighting issues using the standard ecu a lot of the time.
