EMS development has gone well. The D-Jet replacement with DIS ignition is a success, very pleased with how well it drives and the ease of setting it up. Now a second opinion is required to gain additional field experience.

One unit will be given away in return for testing the unit, and providing feedback in a timely manner.

This first candidate must have the following qualifications and equipment:

1. Experience in using RS232 terminal program (Hyperterm is an example) on a portable PC.

2. A donor car, Porsche or VW with 1.6L, 1.7L or 2.0L D-jet system, due for replacement. Fuel system and engine should be in good working order.

3. Electrical and mechanical skills: capable of replacing a distributor and TPS, mounting coil and unit, setting dead timing also following a wiring diagram.

4. Engine tuning experience. Basic trouble shooting skills. Experience with multimeter.

5. The ability to work and resolve issues if they arise using e-mail.

6. The time to do it! If everything is ready, a few hours for install.

Beta testing will begin in about two months (after holidays).

"There can only be one!" (Highlander)

If interested please send to me offline in 500 words or less, enough to convince me you are the one.

Please no hard feelings, if you are not chosen at this time.

Keep up the good work, Kit! Please post dyno results (including A/F ratios) when you can. (IMG:style_emoticons/default/clap56.gif)

Charles,
No dyno other than seat of the pants yet. Throttle response is terrific, drivability excellent cold and through warm-up, just like a new efi car. Idle is very strong, pulls like a tractor. I do not expect significant gains, just better tuning, picking up a few to several HP, in weak spots of carbs or on modified engines with stock D-jet. After driving the car for a few days under varying conditions, I am very satisfied. Finding places for improvement is difficult. May go north to find some colder weather this winter.

Seat of the pants fuel calibration worked, test drives afterward with 5-gas very good, surprised me. Typically 12:1 under acceleration, 15:1 under light cruise. Head temperature in lower valve compartment corner ~94C and very stable +- a only few degrees. The basic fuel calculation based on RPM,MAP, VE, and intake temperature seems very good. All operation is open loop at the moment. I need to change to a header to place the O2 sensor.

This may sound funny, I think I have an Angel that knows EFI at my shoulder. An engineer typically depends on all sorts of instrumentation for decision making. Intuition is the winner here. Guesses for enrichment values, prime pulses, and control strategy have been very lucky!

I found that air intake temperature at manifold was high (57C), and relocated with a short hose, lowered temperature by 15 degrees C. It is nice to have all the diagnostic information available. Cool => higher air density => more power. I think it is possible to make it lower with insulation from engine.

I am locating parts for a home built dyno using hydraulics. I expect only crude HP readings based on calculations involving pressure and GPM flow. Main interest now is load device.

Hope someday to work with Jake Raby on one of his Massive engines on a real dyno. (IMG:style_emoticons/default/laugh.gif)

Brad,

Sorry, I was not at the MUSR. I have been having a hard time pulling myself away from this development work. I want to go to the MUSR some day. I do have to get out more.

Interesting. We had a Kit Carlson at the MUSR from TN.

I'm insterested in being "the" person but I'm not writing a 500 word "summary" of why I should be the one for testing. I do enough "writing" on this BBS and 914 support that I should qualify because I'm "me". I'll do actual dyno pulls and install it on 2 different cars. One with a bone stock 2.0 engine and one with a stock cammed 2056.

I'm highly interested in marketing something like this and have held off because Megasquirt didnt have a easy ignition control option.

I also have 4 engine builds coming up and all of them are 2.0 engines and any of them could use a more aggressive cam and a aftermarket injection system.

What I'm trying to say: send it to me. I already know injection tuning and carry a laptop to every race.

How about if 500 of us send in a one word essay (well okay, not really an essay then).

Here goes...

"Brad".

Now we just need 498 more. (IMG:style_emoticons/default/rolleyes.gif)

oh great, now you are starting to sound like my wife (IMG:style_emoticons/default/finger.gif)

So what is the deal with my heads?

Are they complete or can we catch him in time to install my new stainless valves??

Thanks Swood ..LOL (IMG:style_emoticons/default/laugh.gif) that is funny.

They are not done.. and we can have him install the new valves.

I spoke with Raby. I need all your parts. I'm going to send a pallet to him with 4 engines worth of parts.

David,

I have a Palm3 and a Palm 5. I also have a Casiopeia (sp?) with Windows CE. Laptop is a Dell running W2K.

Instead of Rs232 you might think about RJ45. This is quickly becoming the standard for communication with programming small devices.

I can also help source a mass board manufacturing place (7-8$ a board).

I see in your bio that you built an electric car. Do you know Otmar from Electric Cafe ?? He builds some of the most extreme controllers I have ever seen for Electric car drag racers.

Ok! Ok! Brad is the "One"! (IMG:style_emoticons/default/smilie_pokal.gif)

Thank you for all response, sorry there can only be one.

Looking forward to the tests.

(IMG:style_emoticons/default/huh.gif) RJ45 is just the connector, which in your case is ethernet. I don't think he wants to build an ethernet hub into his controller (IMG:style_emoticons/default/wink.gif) (snaaaark snaaaark snaaaark - geek humour)

RS-232 or RS-442 will always be the way people do this, as just about anything can cable up to it and run. Now there is no reason that it shouldn't have a nice high density connector on it, like, say, a RJ45. RJ45's corrode though, so they may not be best in the harsh automotive environment.

Kit,

One question... how do you think this setup will fare as compared to the SDS kit (effectivity and cost)? I know a type IV guy who swears by it.
