SDS vs TEC II vs TEC III...?

Kierf - ¿§? · 01-25-2002, 06:12 AM

I've been following the posts regarding the stand alone engine mangement systems. I haven't found a clear answer as to which one is the best. All require lots amount of dyno time, no problem...and someone who knows what the hell they're doing, no problem.
My final goal is about 400 RWHP, and I'm thinking I shouldn't even bother with a MAF kit (unless I can find one dirt cheap

) and just save for the stand alone + all other things needed for it to run properly.

...but which kit is the best? I know rage has the SDS and (from what I gather) doesn't have any problems with idle, running rich/lean, etc. Who has a TEC II or TEC III that runs like a champ? (I can't remember who does...I'm getting old...)

Thanks.

Kierf,

Got a TEC II. Isn't running like a champ. Today I'm going to drag the computer out & take a look atr sensors & set injectors.

I think the TEC II is better because it allows a laptop instead of the programming box & has data aquistion.

Does the TEC III allow for tuning with a laptop?

Anyways, if you make any progress with your TEC II, please let me know. Either post it here or shoot me an e-mail at kierf@kierf.net. I'm really undecided if I want to bother with a MAF kit or not...

How much is a TEC II system?

EGSMachine · EGSMachine's Garage

about 2 grand. not including parts.
an sds is about a 950 plus inexpensive parts.

Got my TEC II for $ 1450 - $1500 with trigger wheel & sensors if I remember right. It was about a year & a half ago. Since I put it on a different car than intended, I got another trigger wheel & pickup for about $ 100 & to get a TPS that would fit the D shaft on I spent about $ 90 for two to try.

How hard are they to program. or maybe a better question would be how are they programmed, just fill in the blanks for various values in a set program or do you have to write the program? Where can i get more information on the sds system, as well as the tec II?

Chouse,

Having a hard time programming my TEC II. It's not the TEC II, it's my equipment. My old laptop will read from the TEC II in the Monitore Screen, but it gets a Com Error when trying to send a program. I have to wait till school family members aren't using the big computer so I can drag it out.

The TEC II has Bin Files that come with it for example. You can open one of these & edit it to fit your application. The software has a programing wizard to help you with injector turn on time, etc. The Wizard asks you motor size, HP, # of cylinders, # of injectors, injector capcity, etc to help you set up a program.

Sunday, I drug out the big computer for a couple of hours. Played with the timing & injection time on. I have the O2 unactivated but you can still read it in the monitor screen. I told the Wizard 24 lb injectors & am working toward less to get more turn on time. The monitor screen shows lean & not much on time.
I quit wioth the glare & all trying to read the big computer screen. Going to fiddle with my laptop & get it working or get another. The car cranks & runs for short periods.

In the edit mode of the TEC II software, you can set timing acording to RPM and MAP. Injection is set according to MAP & RPM & throttle opening. Engine & intake TEMP is set to adjust as you see fit. Had to edit the timing to get it to fire up the first time. It's about like moving the distributor on an old point type motor, but you do it on the keyboard.

The way I see it you get running then drive in the data logging mode to see how everything is doing & tune from there.

The car the TEC II is in is an early 85 nostart 944. Today, I put the relay & fuse panels up where they belong & was putting switch, turn sig, wiper, steering wheel in before my coon dog got loose & I had to keep him from terrorising the neighborhood. Still plan on belts, got them, new hoses, got them too, & changing brake , motor, & trans fluids. You can see I'm a good ways from driving.

Don't really know if the injectors are good, so plan more troubleshooting.

One thing about the TEC II that is bad with Porsches is you have cut off the switch to recrank. When programming to start this was aggravating because with the way I wired mine, the TEC II has no power when the switch is off. You gety a Com Error & have to retry on the software to get back to the monitor screen.

I choose the TEC II over the SDS because it programmed with a laptop instead of a keypad. I thought if the keypad messed up in the future, I would be in a bind. With a laptop that isn't right I'm in a bind now, but theres lot of computers.

Thanks Drew, it sounds like it would be really intersting to tune with. I found the electromotive site, but haven't had enough time to really sit down and read it, but i will soon enough. Good luck, and I look forward to hearing more about how its going.

Can you post the link I would like to read about it. Thanks

I have been reading about these for some time........ and in the last issue of sportcompact car (ricer rag)............ (don't flame me)

This unit from aem got top marks............it has preset vehicle plug ins........or you can create any in and out readings......... it looks slick....

most of the engine management systems out there require certain type of sensors or can only drive certain type of injectors...this thing will do it all

the system will take any input you want and give any output you specify.....

comes with a generic harness..........

I saw that AEM EMS at SEMA a few months ago. It looks pretty good. However, considering AEM's market, I'm willing to bet it is mainly for Hondas/Acuras but may be fit to anything else...how difficult it will be to use and what not...I have no idea.

The electomotive site is:http://www.electromotive-inc.com/ The AEM looks like it could be interesting too. Who make the SDS? I'd like to find out more about it as well.
