SimTek vs. ECUTEK

Its done that way to give you better vertical resolution over the range the car is likely to use. You can extend the exponential curve if you start to explore greater flow rates. There are two unused points on the end of the pre 97 green 160 MAF that we use to stretch the MAF to its limit. As you can see though, the gradient is so steep at the top end that small changes of voltage equate to large changes of airflow, so its accuracy is diminished and can lead to a noisy load figure when you approach saturation.
Yes.
Although there are ways around it.
It means re-jigging all load related tables

Just went from ECUTEK to SIMTEK - maf has gone alas!!! thanks to the jolly green monster - supplied, fitted and mapped!
Car runs so much smoother, more "torquey" and just runs like a dream, I was debating getting an Evo but I think I have fallen in love with Subaru driving once again. As I told Simon(JGM) the very next day after having the ECU changed, was driving to work and came up against a rather posch looking M3 - what can I say 30K's worth of german engineering against arguably 6-7k's worth of Jap engineering - the result well, lets just say I had a huge grin - wider than ever before!!!
One of my biggest issues was the car idling, endless problems, but alas they have almost settled , some minor tweaks are needed and JGM will be coming down to do these - fantastic service and a quality product. Anyone with a 99/00 - or any other model this is a must in my opinion

Draw through is the standard MAF location.
The ECU isn't giving you more torque, it's the numbers Simon has flashed it with that do that by turning the boost up. This is true of of any remap, independent of the hardware. Good that your idle issues are almost sorted though arguably an expensive way to fix it.

I am suprised you had idle problems with Ecutek? Normally known for having manners the same as an OE ECU low down and at idle. Not suprisingly as it is the OE ECU.

I can certainly supply, fit and map it.
For Approx £75 you can have the programming lead and software disc to play with your own maps if required.

OK, as I'm quiet, I'll step aside, and leave you two busy ones to fight it out!

Lighten up! just kidding.. It was the fact of all of us on Mark28's list popping up one after another. With JGM on the end, it's a set!

Being fair of course, that list really should also have Steve Simpson on it!

sorry for not posting back after i made a post with a list on names on it but the past couple of days have been crazy! lost my job for a start! 
.
anyway i am just trying to find out my options as to who i can go and see about a simtek ecu.
one other thing is that if i but a simtek do i only get the software to map that one ecu??
as i'm possible looking to buy 2 maybe 3 units, i dont want to have to have 2-3 programs just so i can map the cars ??
is that how the "mappers" are having to do it or do you they have the software to read all ecus with one software kit??

biggest flaw with the simtek is lack of nock control, if that was sorted then simtek would be the way to go, but since its not personaly i wouldn't want rid of the nock control.

yeah i agree on the syvecs bit, not sure if i'd want to risk not having it just to get an extra map in.
horses for courses i supose

I have seen the results of people assuming they can run their car on anything they like because the stock ecu will take care of it.
It isn't pretty.

Ultimately If one was to spend between 3-5k on an engine build, you would want to protect this investment the best way possible e.g. active knock control and wideband fuelling.
I see the syvecs as one of the main reasons of being able to run a GT30R @ 2 bar on a standard engine and I had a choice between the simtek and syvecs at the time.
