N2o

Don't think were ganging up on you Steve, were not, end of the day you want the best results, we can all see that.

Do you remember your back from Noble thread, the RR guy said it made no more power at 16psi as it did at 13psi, this is because of this reason.

It won't be down to chargetemps, 3psi doesnt make that much difference..

so a simple chip will run the motor ok ish at around 1 bar, but a mapped piggy back wont

Would love to post up some reply from Dastek, but im not going to

Send Davids post to them then post the answer! Having seen all the posts about this subject I suspect you are alone in thinking your Dastek is doing the job of a programmable ECU. How is it mapping the ignition for starters????

No he's not
I BELIEVE

Ill supply you a piggy back unit if you like Lee, £300, easy to fit, its only 5 wires..

Its a bargain

:

A chip is part of the ecu, and will directly control the injector drivers, so yes.

For instance, if 5v signal on the map is say a 300ms injector pulse, then the Dastek can only replicate that..

A direct chip in the ecu could change all the settings so that 400ms is the max pulse width.

Its a bargain

lol, im not joking.. , I am a dealer..

Steve...we really need some replies from Dastek to answer this question.....I think most people on the forum would like to see what they say. The fact that David sells things like Dastek but wont sell them to us GTA owners is a good indication that they dont work.....if its as cheap and easy as £300 and 5 wires I will be at the front of the queue. The fact that no one has done it before, we have no results to prove it works and there is no one with any knowledge saying how it will work leaves me thinking it doesnt work...especially as DG has pointed out why it doesnt work. I would be interested to know how its mapping the ignition for starters.

This is your bunfight Steve



All I'll say is the Dastek unit has been fitted and is showing results of some sort whilst the mythical Adaptronic has yet to be seen

Thats because its more than 5 wires!

Lee, 13psi is within the realms of the original ecu..

At 13psi on the stock ecu, everything is fine and dandy, fueling ignition etc...we don't need any more fuel etc..

What we need is mapping and fueling beyond the limits of the factory ecu, ie 15psi upwards..

A chip is not simple. It is a complete mapped or mappable replacement for the original ROM or EPROM with no restriction on parameters.

You only fit a piggy back when you can't easily change the chip and then you are limited by the parameters of the standard ECU. However it's an easy route for complex modern cars with immobilisers built into the ECU.

You pay your money and take your choice.

Piggy back = ££ & limited potential gains.
Replacement ECU = £££££ & unlimited (by the electronics!) potential

No one would buy aftermarket ECU's if you could do everything with a piggy back.

How many more wires and are they connected to anything other than a bank account

A standalone is only about £100-150 more than a fitted piggyback.

It isnt for me to get into the tech stuff re the ecu and the dastek, but surly there is some contradiction on here re power ect the thread started off about N2o as a aid to boosting power, but now it seems that the ecu is OK for boosting power with standard internals, So Peter why are you wanting a ECU surly not to boost the power I believe the Dastek is well capable of providing enough power = £ for our mentioned 20 year old unmodyfied engine internals OK the Stand alone ECU would no doubht come out on top if i/we were chasing mega power with uprated internals, but who on here is going to be doing this Peter

Regarding the simple Chip Stephen? The point i was making is that a chip is fine at running 1 bar but not the Dastek

What would we want a stand alone ECU for if not to hype the power of our poor old V6's more so when "nearly" every one on here seems anti power + looking at some of the older threads it does seem that 300bhp is the tops re; sensible (ish) power which the Dastek will be able to control.

Also (Without been bothered to look at my graph & taking into account the difference in Rolling roads) i dont think theres a lot of difference with my graph and Peters WITH THE EXCEPTION that i was running 13 psi With NO cooling aids at all

Last but not least I would post the reply from Dastek but i suppose there maybe a legal thing Peter re; the replys were addressed to me only, i would hate to do somthing unlawfull

A standalone is only about £100-150 more than a fitted piggyback.[/quote]

So how much is the standalone ecu going to cost inc mapping Dave Without looking i think my bill was £600 and somthing which included the Dastek, mapping and fitting & setting up the Appexi boost controller.

Some Dastek advertising

I'm not anti power

I've got 3 PRV 24v engines, a standalone ECU and a Rotrex supercharger with oil cooler cluttering up my living room!

the thread started off about N2o as a aid to boosting power

I'd like some of that too
