DTA engine managment.
Turbo Mini Forums

hi, im going to be using DTA on my new turbo engine when its finished, i love the sound of it and it dosnt have to run an edis pack it just has coil to plug which aparently creates a lot better spark.

just wondering if any1 here has used it, and any feedback on it.

Cheers.

why DTA in particular Rick? you're not running EFI are you? so you'd just be using it for spark?

yep just engine managment, no fuel injection, but it has some very good specs. just wondering if anyone has any experience with it, another advantage of it is that a lot of RR's will know the system well as its used alot in pretty much all makes of car.

Waste of money on a 5 port engine using a carb.

any reasons for this?

and its a PIA to wire and the people who make it are not at all helpfull when anything goes wrong trust me been there done that bought the T-Shirt

did it work good when it was working?

there are plenty of other systems out there that are much cheaper and more widely used in Minis.

Things like emerald, and omex are used much more regularly, as well as of course megajolt and megasquirt for a fraction of the cost....

NO

I use a DTA on one of my cars, and have found it to be fine. However as you cannot use the fuel side on a 5 port you may as well save the dosh and use a MegaJolt.

ok, i will have to do some price comparisons and see how much all the different options are, thanks :).

You can get the DTA S40 Pro in an ignition only version

i thought that was the case but im not sure to be honest, and liked the idea of not using an edis. however im still to find out the prices yet and the details, i shall have a ring tomorow and see what is on offer and at what price compared to other makes mentioned, obviously megajolt has the big advantage of the amount of mini's using it, so it is proven.

some of the features on there are amazing, but can they be used if your still running a carb?

obviously it all depends on price aswell.

martin is running it on his turbo and has it set with launch conrtoll and some other facny stuff and i think his is still carbed.

does megajolt offer all these sort of functions?

sorry i really am a noobie when it comes to engine managment...

The S 40 will not do the coil on plug. It will still need a wasted spark coil.

I'm biased towards Megasquirt because that what I use. That will do all you need and more, plus you can save a bit of money by building it yourself and learn a lot as you go.

Even with a carb you can have coil on/near plug, launch control, boost control and even traction control.

Most ECUs can do this these days but they are expensive.

However, if you have not used anything like this before and are not familiar with electronics, then start with a Megajolt.

Leave the DTA to the bench racers in the pub.

haha :) liking the bench racers comment.

ok thankyou for the info its much apreciated :)

do you have a rough idea on the price of a megasquirt/jolt system if i get all the edis stuff myself?

I use DTA and its very good for what I want (bmw k1200 on injection) .. the ignition only kits also work very well on carbed engines.. lots of features you can use and easy program to work with.

Wiring not too difficult just a bit fiddly with the small connectors!

IMO megajolt just doesnt have the features or accuracy of the DTA software. And as you said alot more rolling roads deal with DTA more than Megajolt... including ourselves.

Chris @ Smart Performance

really conflicting view here then...

but is it still the case that DTA is alot more expensive than megajolt?

Yer alot more expensive. But in my view, you get what you pay for :)

thats a fair comment.

My RR operator recommends Polestar and this is a stand alone system requiring only the usual coil pack.

IIRC there are only five wires to connect and then the sensor to mount and a "chopper" plate on the front pulley as with the toothed wheel for MJ.

The greatest advantage is that the ignition map can be adjusted with the engine running on the dyno so results can be seen instantaneously _ I cant do this with my MJ V3 although I dont know if later versions can.

Any comments/experiences with Polestar ?.

Cost is an issue because, with a Map sensor, its about £550

DTA is very good, and you have various models to choose from to satisfy your needs.

Personaly I would be wanting more from it than just the ignition side.

VEMS on the otherhand would give you wideband, EGT and coil on/ near plug in with the price. There was a chap on the continent that has done just this on a Turbo Mini, somewhere.

Oh and not forgetting dual config, and SD card logging as an optional extra

I am biased towards VEMS as Paul is biased towards Megasquirt :)
