Emerald v DTA S80

[hiltonig]

Hello chaps a few questions

Anyone fiited a DTA S80 and how did they get on, Looking at the forums the Emerald is more popular and it is attractive as the DTA has a lot of stuff that I may not use and costs more.

Also how many wideband sensors can the Emerald use, and what is the recommeded type , is it the LC1 from Innovate ?

Also what to do with the stepper motor, not sure if either of the above can drive it ??, just ditch it ??

Finally does the alarm have any interface with the ecu ??


Thanks for the replies

You might want to add the Omex 710 to the debate...I know I now, just when you thought you'd narrowed down to two options...

When I looked into the options, many told me the Omex was more versatile than the Emerald, and was similar money for the kit.

I have an Omex, and although it's a little like a curate's egg (good in parts), I suspect that's mostly down to the numpty who fitted it (not me).

I fitted a DTA S80 to a hybrid ls7 recently. The softwarew is very good, easy to use and it didn't take me long to familiarise myself with it. I also liked the diagnostic software, all you had to do is crank the engine and you could view an oscilliscope trace of the crank and cam sensors as well as all the other stuff. Information is stored in a history menu so you can easily check for faults. It has sequential options but doesn't support idle air bypass which is a shame. It also doesn't recognise the lsx cam sensor which means no sequential operations. That said, DTA may be able to rectify this but I don't care about sequential injection. It has traction control and is said to be easy to map for fuelling with an innovate wide band but I never got that far with it.

I can't comment about Emerald.

From what I remember, the DTA was the most expensive, followed by the Omex 710, then the Emerald was cheapest (feel free to correct me!). I've just got the Emerald finished on mine and it runs absolutely great and was a bloody good investment IMHO. Little things like quicker revs, no low down shunting, easy control of the fans, map switching etc just make it a pleasure to use, plus the user interface is very easy to use.

I can't comment on the other systems, but the Emerald uses one lambda input (wide or narrowband) and doesn't use the original stepper but it was very cheap and easy to plumb in a new one although it doesn't *need* it, it does help cold starts. Search the forum or my previous posts for the stepper details..

I ended up going for the Emerald because it worked out about £500 quid cheaper than the Omex (even less on the group buy I organised), I liked the software and ease of use, and I couldn't see myself using the extra features on the Omex/DTA (or even some on the Emerald!).

No, the alarm doesn't interface with the ECU

The Emerald has a single NARROWBAND input ONLY.

You can add 2 x ANYTHING to the 2 AUX inputs, including if you want, 2 x WIDEBAND Lambdas but you will need their controllers too.

The Emerald has the ability to have firmware upgrades. It's new version is great and getting better with the upgrades.

It also has the ability to store 3 maps and switch on the fly.

Therefore you can have a high octane map, another for 95 octane and the third to run closed loop.

The other ECU's with only one map can have the ability to retard the ignition by a fixed amount at all rev and load sites. This can allow you to run low octane, but without the timing being spot on, unlike a dedicated low octane map that can be fully configured to be spot on all the time.

Or have one map to pass the MOT and the others for maximum power & hang the emissions....

or just sit in the MOT station with the laptop on, altering the idle are of the map till the map with the probe says ok
