i must add, that with regards to everything else simtec related im over the moon, car drives spot on, fuels nicely, boosts nicely, etc etc, im just not happy about the frankly poor idle, and that is something that i cant live with as it is now, and as far as im concerned, i shouldnt have to!!!!

I just want them to release the updates already as I only want to send my ECU from Oz to the UK once instead of sending it now for the wideband function then sending it back when the knock & idle updates are ready.
Dont regret getting the SimTek though, car drives like a dream.

if your confused then im stumped completely, the car idles terribly, yes it may sit at 800rpm or it may sit at 1000rpm, but when we got back on sunday it was sitting at 1300rpm stationary and warm?????, then it might drop to nearer a 1000rpm the next time it idles etc etc, so yes it may well hold that particular idle speed at that specific moment in time, but surely the idle speed should be the same everytime the car is in the same situation, not fluctuating between 800rpm and 1300rpm depending on how it feels????

This is no reflection on the very good mappers who have maped the car. But it is very hard to get right, as the issue is is that the problem is so inconsistant. Everytime the car has left a mapping session it has idled perfectly.

syvecs is something that im seriously considering, i cant put up with the idle as it is and just put it down to the way the simtek is!!!! and i shouldnt have to along with all the others that are suffering the same issues.

i must say i had initial problems with idle at cold start, the mapper hadnt seen the car cold, so a quick visit from him and mine idles faultlessly all the time. The one thing i do have to do is clean my icv once every 6 or so months as it gets pretty gunked up. i put that down to the coolant pipe delete on the throttle body

This is a very interesting thread, I've got a simtek fitted too and my idle's a total nightmare.
Been back to the mapper who did improve things slightly and recommended a new ICV. However this hasn't fixed it.
When it's started from cold or hot it will stall unless I press the throttle and keep it pressed. If I take my foot off it stalls. It will do this for a couple of minutes then comes allright and 50% of the time will be fine and idle at 900 rpm, the other 50% it will hunt like mad on idle, eventually stalling after a couple of minutes.
It's a nightmare coming out of carparks or petrol stations, my Mrs refuses to drive it and it can be very dangerous pulling out of junctions.
I can't afford to go back to the mapper again for a while so I guess I'll have to live with it.

I have a syvecs and I get idle problems but nothing my mapper or Pat Herborn have not been able to resolve when I've asked. An aftermarket ecu will not necessarily resolve the problems - there can be other variables relating to idle as I have discovered.

guys my idle is spot on even with cosworth cams, RCM light pully kit and light fly wheel with the simtek but it did take 2 visits to sort
what took the longest was nailing the off boost driveability but a few loops of swindon town centre one evening has it close enough. I find the car needs to stand for 30 seconds to 1 minute before its good and guess this is more ECU related than mapping
not perfect but im sure the spec of the car doesn't help - if you guys are having issues with idle i really suggest you have a word with your mapper - you mention being charged for a return visit, I know Bob in Swindon woundn't except any money to sort my niggles

I did go back to them after my first map as the idle was even worse previously but I've not been back since. I will give him a shout and see if he'll help me out.

He ought to mate provided its not been fiddled by anyone else since the first map. I had mine tweaked only last week - took 20 mins or so.

Simtec upgrade delay
I have heard that delay in getting updates out is that it is low priority because they are developing new ECUs for newer model cars.
Simtec, don't p~ss off your existing customer base.
It would be useful if someone senior from Simtec could comment?

Yes you can, the only thing I dont like about the datalogging is that it wont recognise a wideband without an update. The only thing you see is a rich/lean indicator.

yeh, and out of all of this, this is the most annoying part, as it is basically down to awful customer service, sell something to someone, then when they have problems, forget about them that have been sold to and move onto the next batch of customers, who no doubt will be spun a line from a salesman, and once more be forgotten about when problems occur.
looks as though this thread has at least been useful partially as at least 1 person is now reconsidering buying simtec because of these problems, keep it at the top of the board until we get the issues resolved satisfactorily, we might get somewhere then!!!!!

The ecu is only as good as the person tuning it whether it be a SimTek, Syvecs or Motec matters not.
The original poster had his idle issues resolved at his convenience, FOC and it took no more than a tweak.
If you are having issues I suggest you take it back to the mapper and have it looked at again. Unless the car is faulty there is no reason why it can't be sorted with or without closed loop idle speed control.
If he still struggles to get it right, bring it down and i'll sort it !

PM replied to.
In addition I would like to say that for in excess of 1000 units sold, I don't consider 5 to be a load, lol.
