In my research for better engine management and forced induction tuning techniques I found:

Simple Digital Systems E.F.I

http://www.sdsefi.com

This system is so much easier then a Haltech. Fully programmable, fuel and igntion. Able to put the car in closed or open loop at any 250rpm increments. Able to have 164pt adjustability and uses its own handheld to do it. (dont have to buy a laptop too).

The price is AWESOME. Its my next upgrade.

A friend of mine is running a 74 Toyota Carina with a 22RE with a T72 Turbo. The motor is 10:1 static with 25psi on AmPm Pump gas!!! If you live in the Phx area you can see his Carina at Speedworld on Saturday nights.

That looks like a nice system...BUT :)

I'd rather have the data loging and realtime tuning that you can do with the E6k from haltech. Not to mention the nifty little tuning nobs for extra fun on the street.

The Haltech ins't really that much more. I was just looking at my Haltech price sheet and I could do the E6k with the "flying lead kit", 3 bar MAP sensor, and 4 wire O2 sensor for $1,225 + shipping.

all the info is at http://www.haltech.com.au/Products/ECUs/E6K/E6K.pdf

I downloaded the software about a month ago and played with it a little bit. It takes a little getting used to but I was more than excited to try it out. I think the posibilities are darn near endless.

Haltech's aren't worth the headaches though. I talked t Orlanado last fall when he sold me the MSD box and AFC....he told me he was having problems getting the haltech set up for him.

And when I talkedto guru's of guru's, Denis, He was having a tuning problem and couldnt rev over 4k revs.

the SDS is really simple to use.

My friend Rob looking into being a retailer for SDS and found out, you can actually datalog with one of the models.

Another cool feature about it...if it starts acting weird you dont have to send it away to get it fixed. They send you a diagram of places to check with a DVOM, and if somethings broken on the ECU, they send you a list of radio shack available parts to fix it!

Its an awesme set up.

Haltech....well, Pro Rally Racers use Haltech. LeMans racers use Haltech. Haltech has been around for ever and is of the highest quality.

So either way is good...but I'm definately going to try this SDSEFI set up.

hmm... Denis was going over all the goodies with me a couple weeks back. I'll have to ask him. I got the impression his troubles were more a matter of having time to fine tune the system. However like I said I don't know for sure and don't have any experience using either system. I do like the fact that the SDS unit works with a halndheld control but I guess I like the fact that the haltech can be updated easier by its design. I guess in the end it comes down to ford VS chevy all over agian :)

Then there's the MegaSquirt... and MegaJolt. :D

I think a lot of the features on the Haltech are useless without a lot of dyno time. You'll probably be able to get more HP and driveability out of a Haltech, but getting there is a bit of a headache I'm sure. The SDS is so simple.. it sounds easy.

* really has little clue about the difficulties involved in electronic engine tuning, but will chat all day about it regardlessly :D *

The Haltech sure looks like it takes time to learn that is for sure. I guess I'm more comfy looking at a computer screen with all the data then a LCD but that is only my oppinion.

I E-mailed SDS about becoming a dealer. I got a nice little E-mail telling me all the ways I could lose my dealership status and that I'd have to by two units to even get a lame discount. I was a little ticked. I'm sure they get a lot of interest but I'm not going to spend extra time "prooving" to them that I'm worthy of their product. It's cool that they only want people to sell their product that know how to use it but I get a "high and mighty" vibe that I wasn't to excited about.

So the moral to this story is if you want ease of use have someone reprogram your ECU. If you want infinate adjustability and you don't mind learning how to do it get yourself a stand alone system.

I have run both the SDS and Haltech system. The haltech program can give you a head ace and you get little support from haltech, but is a great system once you figure it out. I had problems with the ignition set up in the sof ware it was completely backwards from what I was told it should be. Car runs great now. All I need now is a heater controler for my wide band O2 senser and some dyno time. Haltech is set up to read wide band. Data logging makes street tunning nice. I car make a pass down the street log it and check it out later. Lap top needed.
SDS system is really easy to use, installing the magnets and hall senser can give you a head ace, but isn't that bad. I must say the have great customer service and support. No data logging all by guess and on the fly. No laptop needed.

I still have my SDS system, I need to send in for a repair I oops on it. $60 to fix no biggy. I will get it fixed and get new magnets for the timming pickup if some one is serious about buying it.
As a package deal!!!!
Basic SDS system with 3bar Map senser, 550cc/min high impedance injectors, crane HI6 ignition amp. Since it needs to be fixed anything extra can be added to the system you want you pay extra cost, like knock senser controll, Fast Idle, etc.......
SDS uses an ignition amp such as 6A, 6AL or HI6 as a trigger for the ignition system, won't run with out one.

As is fixed with new magnets, injectors and ignition amp $800, +shipping
Not fixed you want to send ti in youself, $700 +shipping

Hey Denis,
I'm REALLY interested in picking up your SDS...but just dont have the money...but I do have a birthday coming up next month.

I'll be sure to check with you before I run out and buy one ;-)

Thanx for the compare and contrast from actually having both...really helpful.


As a side note away from Escorts, but with Haltech....Haltech systems can be more helpful if you decide to go really crazy with a set up. Most people dont know but they have the ability to be programmed with everything from single turbo, to twin turbo, to quad turbo and all that with use of oxidizers and if you think out your programming right you can even set up piggyback systems on the haltech, like methanol or water injection and use rpm activated switches.... All in all there's alot more depth to a Haltech then most people would ever use it for.
