Euro 928 EFI Conversion?
Hey Jim Nowak,
Is this your car? It was on display at DEVEK last weekend.
Can you explain the many mods we see here?

I don't know who the car belongs to, but it's having a DTA engine management system installed on it. The DTA is fully programmable, with individually controllable coil on plug ignition, sequential fuel injection, MAP sensor, the ability to run closed loop with either a narrow or wide band O2 sensor, traction control capability, data logging, rev limiter, and probably a lot more other neat stuff.

This car started life as a high mileage 83 4.7 euroS. Our shop, DynoTECH, built up a nice 5.0 l short block, gently massaged the heads and kept the stock cams. Kept the stock manifolds, added some hig flow headers and popped 300+ rwhp on the dyno.
However, the CIS fuel system would either give us the good hp or a really nice idle and cold start, but not both. We worked pressures and injector sizes...even modifing injectors for fitment into the 928.
Since DynoTECH is a US distributor for the DTA system, and it is the best bang fort the buck (at ~$1600 for the ecu, software, connector and comm cable), and easy to use, we installed the unit, built the harness and as you can see, about ready to fire it up.
We look at all the band aids used to control modified engines and all the compromises and it just makes sense to install a system that can meet he needs of those who want the power and control at an affordable price.
Soon we will have "kits" for S4 and later....as the ecu's go bad, this can be an alternative.
Anyway, once done and dyno'd, I will post results.
DynoTECH is offering a special until Sept on the P8Pro units at $1400 each. Email me. See <a href="http://www.dtafast.co.uk" target="_blank">www.dtafast.co.uk</a> for more details.

Marc

Marc, how soon for the S4- cars?
Will those of us who would like to make this conversion be able to retain our digital dash goodies (89-)?
If the answer is yes, you can put me on the list of DTA Pro8 recipients!
Cheers
Max
P.S.
Marc, the motor you and Jim built for me is doing great.
I'm at 310/312 now, with DEVEK L2 headers and the Pro8, Humm?

Max -
The DTA computer and the the 89 digital dash, frommy current research, WILL work together. The digital dash needs a tach signal that it currently gets from the LH,a nd that is it (or so I have been led to believe).
Obviously, more will have to be hashed out.
But the DTA is the best bang for the buck that I can currently see, and I have been doing EFI research for about 11 months now. The 1600 price of the unit and peripherals (sans the wide band 02, but I am not sure how much that is - maybe marc can chime in here) can be easily offset by the selling of the LH, EZK, and MAF, as I am trying to do currently. The wiring nightmare that ensues is another story, but it is the price of admission in my mind to the world of unlimited tuning potential:
Live in CA? Make a new map for 91 octane
Tired of 91, make a map for 91 + Toulene
Driving to the East coast? Make a map for 93 and 94 octane and save it on your laptop!
This thing has so much to offer, and so much ability to handle any sensor you throw at it, its is really the solution to many (maybe not all) of our worries. Even simple changes like headers, exhaust, and maybe a bit high fuel pressure and somenew injectors can be tuned for maximum use.
Anyway, enough waxing poetic - its really just the best all around solution unless you want to spend 7-10k on a motec. I suggest to those who are planning on this, to download the software from the site that marc listed above and play with the software, and read the electronic manual.

Brendan, the wiring is less of a concern to me than losing, MPG, Miles till empty or any of the other factory goodies that come on the 89-up cars. I'm sure Marc and Jim will come up with a solution for this in time.
Like you, I have been looking into a brain transplant for my 89 for sometime. The pro8 looks to be the ticket, it offers way more flexibility for the price than any other I have found. I like the idea of strapping on eight coil-over plugs, witch means no more cap or rotor and long spark plug wires as well as the wasted spark system!. O-yea, lets not forget the Pro8 is sequential injection rather than the batch injection system we currently enjoy.
I watched Marc while he was in the first phases of tuning in the Pro8 on a hot little Stang in Tyler Tx at DynoTechnik (Guy's place). I don’t know what impressed me more, the Pro8 or Marc's ability to manipulate each data screen at lightning speeds.

Very cool stuff! Im damn near tempted to get one now as i know the price will go up. By the time you sell the individual components from your car it will replace, you can easily offset a fair chunk of the cost. LIke any gadget, one always has to look at the "tweekablity" factor LOL
