As one of the very first to offer Simtek ECUs we're naturally very happy to build on our considerable experience by supplying the latest system. It certainly looks to be everything the market has been asking for.
Martyn's up to speed and can't wait to get at it!

any more info multiple maps active knock control etc?

Hi Martin

According to Martyn it has everything he's been asking for!

looks good

So to have closed loop wideband fuelling, what is exactly needed? Obviously a wideband O2 sensor, any interface aswell?

averyp2

iTrader: (25)

Are these available now then or are you learning on a concept ecu? What is the retail going to be for this plus mapping?

Any software/hardware updates for exisiting simtek ecu`s to bring them up to date with the new features or is it a case of buying another ecu alltogether.

I believe from the other thread that there is no update unfortunately.

Should this not be in trader announcements?

MartynJ

We'll put it there too if it bothers you Banny ?

Maz

iTrader: (34)

Yes it should be in Trader Announcements, it seems a cynical way to get more attention.

Maz

iTrader: (34)

Stick to the Syvecs a far better ECU.

Andy.F

Where did that thread go?

Alan Jeffery

Cynical? hardly, we are a business, we do pay business dues, and we can post whatever we like on any part of the forum, depending on protocol.
A new ECU could be fairly described as of interest to techies as well as customers, depending on which hat you've got on!
Whatever, we have no objection at all to being relocated, apologies to those of pedantic disposition.

I'll admit to being quite enthusiastic about something new, we have no axe to grind over any ECU option as we supply and map them all.

Is this the one I had fitted ?

Alan Jeffery

No, yours is the earlier one. The new one isn't actually available yet, at least not for around four weeks.

Traction control, could you please explain how this activated, does it have varying levels of control and is there further items required to make it work?

I didn't realise you'd used a new Simtek, I thought me and Steve were the only guys that had! But I guess you know better.

Posting in Scoobynet General Technical was not meant to be underhand, but the above comment certainly is if you've never even seen or used the new Simtek!

Andy: Looks like someone didn't like it in General Technical so they removed it, so I've reposted under trader anouncements.

Andy97: Traction control uses the ABS and speed sensor inputs to then control a multi strategy engine torque control to vary wheel slip to the desired performance.

i didnt know banny had just become a moderator.

iTrader: (68)

Do you have issue with me asking questions?

andy97

iTrader: (1)

So to clarify, I will have a multi position switch/**** to set the degree of traction control and nothing else?

The reason I asked was the syvecs needs a ground sensor which costs mega money for their traction control to work on a 4 wheel drive car

Maz

The above comment is a recommendation based on experience both direct and indirect. Going by the customer support and functions of the Simtek mk.1 I stand by what I said. Now if time proves me wrong then I will retract what I said until then YOU prove that the Simtek mk.2 isn't a case of the Emperor's New Clothes.

PS Commercially motivated threads belong in this section.

MartynJ

I think you'll find as a result of this parting of the ways, that the customer service on both old and new units will improve some what !
