Post Shiv - TEC II questions

Been following the progress of your TEC-II system, and it really looks like a great idea - I've been considering going turbo, but am kind of put off by the current offering's huge amount of add-on electronics.. I'm not a car wizard, and the last thing I need to is blow up the d4mn thing trying to tune it. I had a coupla of questions though, mainly terminology.

1.) Your turbo kit comes with bigger injectors and an upgraded fuel rail - I'm not familiar with the term fuel rail - what's it entail..

2.) It's windows based, correct? So all I need to do is create an engine mapping and push it down the controller. Is there, or is there any chance, of getting some sort of simulation software - it'd be great to be able to at least make sure the map isn't going to blow up the car. This might be a stupid question, but I haven't seen the interface so I'm not sure.

3.) How exactly does this connect to the stock computer? Does it splice in like a S-AFC would, or does it actually replace something?

4.) Finally, if I purchase the TEC-2 kit and have it installed BEFORE the turbo, are there going to be any ill effects using the bigger injectors and upgraded fuel rail. I imagine the car might run rich, but that this could be mapped out..

Thanks in advance..

Basil

Hi Basil,

I actually use the stock rail with the big injectors. All that is required a machined mounting adaptor which is included with the kit. Injector installation should only take 10-15 minutes. Real easy.

The software is indeed windows based. You can create new or modify the baseline map files. Save it as another name as to not loose the old file. Download the program into the TEC by a convential IBM compatible serial port.

Yes, one can install the TEC w/injectors before the turbo. In fact, it's not a bad idea to do so since it would allow one to get comfortable with the software/interface while the engine is n/a and relatively goof proof. Not to say that extreme care shouldn't be taken with NA tuning.

Installation of the TEC-II system shouldn't be difficult. I plan to take installation picture (during Alex's install) which I will include in the directions. Perhaps Alex can put them on-line as well. Hope that helps.

Shiv,

Would there be any possibility of selling the special parts you had machined for the crank pickup?

One of the guys from our club is working on installing a TEC-II on his car, but is having a heck of a time with this part.

Thanks.

So how much is the TECII kit that you're selling Shiv?

what warranty are you offering on your ECU maps?

Around $2k for the TEC with coils, ignition wires, idle control motor, crank trigger, sensors, maps, etc,.. An additional $320 or so for 550 injectors. Another $50 or so for knock sensor mic. Another $70 or so for boost control. Of course, prices aren't finalized yet and won't be for another week or so.

Electromotive has a one year limited parts/workmanship warranty on their components. As for a warranty on my maps? None. Proceed at your own risk. All I can do is minimize risk by giving conservative baseline maps, safe advice and as much general help as possible. Still, there are factors well beyond my control. Taking responsibility for potential problems would be suicide.

What if someone fills up with 87 octane? What if somone ran more boost than the fuel system would allow? What if the fuel filter was clogged and the car ran lean? What if someone over-revved the motor? What if someone somehow managed to install the crank wheel incorrectly and ended up with a whole bunch of mechanical advance and didn't know what knock sounded like or if it was a bad thing? The list goes on. Of couse, these problems are very unlikely to occur if someone approaches tuning carefully. But like everything else in life, the risk is still there. I suspect that I will include some sort of disclaimor in the package that will remind the end user that this is serious stuff and to proceed at one's own risk. I would much rather scare away someone than have him blow up his car through not-so-careful tuning!

Great, that's pretty much what I needed to know - thanks, Shiv.. Since my tuning knowledge is negligable (i'm a computer guy), I'm probably going to have Rallispec do the install, and basic tuning - better safe than sorry, since this is my daily driver.. I'll probably go with the turbo kit and then add the actual turbo later, so, as you said, I can get a little bit of experience before adding the turbo to the equation.. Sounds like a plan - thanks again, and I look forward to actually getting my hands on one..

Despite my blatant attempt at butt-covering, I still think tuning one's car oneself is the best and safest way to go. It's not hard or unsafe as long as guidelines and common sense are followed. It takes some disregard for piston speed and/or detonation deafness to catastrophically pop a motor. For someone with little or no EFI tuning exprience (99.9% of us) and time/willingness to tinker, I think it's the way to go.

Oh, I agree, there's nothing as satisfying as doing it yourself, but I don't even really have a baseline to work from, lamentably.. My motto has always been "See one, do one, teach one".. I just need to see one done and then I'll be a little more confident..

As to butt-covering, in today particularly litiganous society, you have to.. I'm not gonna sue because I was a dip and blew my engine, but someone else might. No problems there - I have to chuckle at most of the "Please don't sue" disclaimers, because some of them are so ridiculous...
