Looking to have a Simtek ECU fitted I was wondering to what detriment ANTI-LAG will have on engine/turbo etc.....

Only looking to use it occasionally

Cheers for advice/experiences

Dave.

 

setup mildly it is not a problem.

just makes lots of lovely noises

Simon

 

Am I right in thinking on a Simtek then that I could have/use the following;

1 switch to switch between 2 different maps
plus
1 switch to activate (mild) Anti-Lag
plus
1 switch to activate Launch Control
plus
1 switch to activate a "valet" mode (rev/speed limiter via fueling adjustments or whatever)
plus
1 switch for NOS (just thinking/dreaming of next upgrade stage)

So thats 5 switches in total!

Also do you have to fit an extra heat sensor to aid controlling/deactivating ALS when temps get a little to high?

Do you have to remove your DV to use the ALS option...I was thinking of having the second map to create some popping and F**tin' on the rev overun..

 

Also, with regards to wiring the switches, would you just have a volt free (NO or NC?) pair wired back to the ECU or can you just send a ground(0vdc) down one wire back to the ECU?


Cheers for help

Dave.

 

lol.. 20 questions..

map switch either on a switch or by using the throttle and ignition off / on squence and the current map is indicated on the rev counter.

antilag switch yes

you can have a launch control on a switch or just enabled automatically when stationary and in gear.. ie. the rev limit is set to the launch control rpm when ever you are stationary and in gear.

yes nos swithc too etc..

the simtek uses an air temp sensor to check air intake temps..
both when ALS is on or not..

you can have a large number of different pops and bang options on overrun
depending on which map and whether ALS on or off..

Simon

 

oh and the switches are ground to ecu to enable.

the switches used are fairly personal to owners taste.. i tend to wire up to switches they have installed themselves already or wire temp switches so the owner can install to his own later..

Other neat options is ALS enable switch as the "bright button" if a UK car

Simon

 

If you want anti-lag, i.e. positive boost off throttle and loads of it, you will run the risk of turbo damage.

It makes me laugh that people say they want "mild" anti-lag and all they end up with is the pops and bangs with no positive boost..... that is not anti-lag in any way shape or form. It's just pops and bangs.

 

How do you do this anti lag thingi, i like the sound i like it a lot. Is it just a case of the mapping, some body please explane.

YouTube - Subaru GC8 Mountain Pass Fun with Anti-Lag

 

is anti lag mapperble with ecutek?

 

Yes, but only on the Spec C ECU and a special ROM afaik.

 

Indeed. It's also illegal for road use.

 

for anti lag, other than posing sake, to have any real affect it has to be set up pretty aggressivly, and thats what will kill the turbo, vlaves etc etc.

it your after pops and bangs then slight extra bit of fuel on the overrun has similar effect and doesn't do any damage, bar the cat, unless of course you dont have one

 

I just love the sound of the anti lag, It really makes me smile when I hear any Subaru banging like that.

I have to get my Ecutek tweaked in the next week or two, I wish I could get the anti lag to run

 

I hope I didn't make you laugh as I didn't "ask" for mild anti-lag Simon merely mentioned that "mild" anti-lag sholdn't cause any real damage, I guess he put this suggestion forward in response to the thread title , and wasn't condescending like some folk hence I put in the "mild" in response to his post.

 

So, do I have to fit an air temp sensor then or is there already a factory fitted one lurking about somewhere

And would I have to remove my DV/temp' cap the hose off for the ALS to operate (my DV is a dual function recirc' and VTA at higher pressure type)
if this is the case I think I'll just settle for a bit of over run pops and bangs for a grin factor in the 2nd map.

I'm mainly interested in the Launch control option but seeing as the ALS comes with it at no extra cost I thought I'd see if it is worth it for a few laughs (not rally stages ).

 

I've just had Simtek fiitted and mapped by Bob Rawle.

The air temp sensor was provided by Bob and fitted to the TMIC.

I have two additional switches fitted in the car -

- one for the anti-lag, either on or off
- the other for the high and low boost maps

Launch control works whether anti-lag is switched on or off.

I'm VERY happy with the result

 

So if I fitted one into one of my FMIC pipes would it be the one after or before the IC?

I don't suppose you could let me know where to buy such a sensor.

Cheers,
Dave

 

I had my simtek from JGM and he supplied the Air temp sensor, was told to fit it after the intercooler close to the inlet manifold.

 

How much was it?

 

as you say the antilag we are discussing here is with regard to use with standard stepper motor/idle valve and no requiring extra gubbins to actually get positive boost and therefore have no brake servo assistance..

see between 0.2 to 0.4bar over vaccum.. (ie. -0.6 becomes -0.4 or -0.2 for example) tiny bit noticable on gear change but not mega.. more for the noise..

lmfao@condescending.. anyone would think he used to own the place

Simon

 

you can get some pops and bangs on overrun with ecutek but without any change to boost pressure. . unless you use the rom file Shaun mentions which no one is suppose to know about.... he said it not me

Simon

 

newage have one already.. the installer of simtek should fit one if required etc..

Simon

 

cool, mine is a newage...

 

Place was better when he did own it though took weeks for new owners to sort out my re-subscription and almost a month on I still have no access to the Scooby shop or any excuses why not.....but thats another thread I started already.......off subject rant over.

Oh yes, nearly forgot Simon, heres one for you

Thanks

Dave.

 

You can also configure this using Romraider on the newage ECUs. Simple case of retarding ignition and richening fuel cells in the load areas the car will access on over-run. No performance gains though.

 

and Launch Control and Flat Throttle shifting

 

Ive known the spec c (twin scroll cars) were capable of anti lag about 3 years ago but wouldnt people just get a similar benefit from a full decat and a touch of overfuelling? (the pops and bangs that is )

Tony

 

yes with ignition tweaked on overrun.. just no added air so you just get the noise.. which is different but still nice
