Considering Tweecer, have basic questions. Tried search.

After reading/searching for info about EEC tuning. I have decided that I want to go the Tweecer R/T route prior to my stroker build. I have a pretty good understanding of the basic operation of the EEC IV. Just have a few basic questions that a search could not answer.

I know I'll need:

Tweecer R/T
BE
EA
WB via EGR (not used)

1) I plan on using a 90mm LMAF, all I need to do is load the transfer function. Correct? Then use the appropriate size injectors and input the corresponding value into the EEC tables? Then tune from there.

2) I'm not clear on how the Tweecer interfaces with the EEC. Any pics? Pics of cable used to interface between laptop and EEC a plus.

3) Is an extra exhaust bung needed for the WB? Or does it replace one of the existing O2's? I'm assuming use of the WB is temporary for tuning and data-logging, not daily driving.

4) I also have a 67 that will be EFI. Any way to use the Tweecer, BE, & EA on more than one vehicle.

I know some of these could have been answered with a search, I didn't have much luck here or on the corral. I'm an engineer and have some programming background. So, understanding of the basic EEC logic is no problem. I'm really looking forward to tuning/data logging on my own without having to rely on a shop.

Thanks in advance.

Edit: I also read a little about Quarter Horse on this forum. I couldn't find any info via a google search. Is it still available? Any preference over the tweecer?

2) I'm not clear on how the Tweecer interfaces with the EEC. Any pics? Pics of cable used to interface between laptop and EEC a plus. Plugs into the j3 port on the side of the computer. Don't have a pic, but it's a USB cable.

4) I also have a 67 that will be EFI. Any way to use the Tweecer, BE, & EA on more than one vehicle. I guess you could. You could move the tweecer from car to car, but unless you burned a chip, the one without the tweecer will revert to a stock tune when you unplug it. Check out moates.net for cheap chip burning equipment.

Edit: I also read a little about Quarter Horse on this forum. I couldn't find any info via a google search. Is it still available? Any preference over the tweecer? Quarterhorse is still available. It datalogs better than the tweecer and is cheaper. It won't read the stock bin off the ford computer, but that's not a problem Bineditor comes with most stock bins. Go to eectuning.org and moates.net for more info on the quarterhorse. FWIW, if the quarterhorse had been out when I bought my tweecer, I'd have bought the QH.

QuarterHorse for Fords [QH1] - $249.00 : Moates.Net
 
Great info! Thanks.

Can the WB still be connected via EGR with the Moates Quarter Horse? To the best of my knowledge, yes it can. If you go the innovate route, you can just hook up it's usb cable and BinaryEditor will read it.

Any preferred WB setups? I know NOT to buy anything by PLX. Can't read the screen in anything other than darkness, doesn't work when it's hot out, horrible customer support, etc...
:nice:
 
Okay. Before I start purchasing, I want to make sure I haven't left anything out.

To get start I need:

1) Moates QH Yes
2) BE Yes
3) EA Don't NEED this, but yes, you need this too
4) Innovate LC-1. Is this what I need: Innovate Motor Sports On-Line Store Yes

Installed per this: EECTuning.org • View topic - How to connect a wideband to the EGR input You could do it that way. Or you could use the serial out and connect it to a serial port on your laptop if you have one. Since you prob don't, you could use something like this serial to usb connector. BinaryEditor will datalog directly from the lc1 without messing around with your egr wire.
Will probably connect brown wire (analog 2) to pin27.

That's all the hardware and software needed to tune and data log, correct?
I would also recommend the rotary switch. It's nice to be able to switch tunes on the fly.

And, as posted above, you don't have to disable your EGR to datalog a LC1.

BE has native support for the LC1. From the BE help file..
Innovate LC-1/LM-1
The LC1 is a Lambda Controller made by innovate motorsports. This controller is
an external device that allows for monitor and or logging of analog signals. The only
required components are the LC-1/LM-1 controller and cable. Each channel is
configured using the Innovative software.
The label and scaling information for each channel is automatically read into BE.
The ability to over write the channel names in BE is available if desired. Each
channel has a configurable transfer function within BE. These transfer functions are
only used if the associated LC-1/ LM-1 channel is configured for a 0-5 volts dc
signal.

Oh, and last but not least, if you have a 64 bit operating system, it's a little more work to get the drivers installed and working properly. If you are, let me know, and I'll walk you through what needs to be done.
 
Good to know about the switch and the USB connection for the WB. I'll keep those options in mind.

I'm running 32 bit XP, so hopefully no problems loading the software. If I need it, might hit you up for some help when I start turning. :nice:
 
That'll work. The transfer function for the 90 mm MAF is in EA and can be exported from there and imported into your tune in BE, so that should be relatively easy. Depending on your processor(A9P, A9l, etc), you should be able to find the template for the injectors over at tunexchange The injector templates will be listed under GUFB strategy, but they should be the same if you have a GUF1. Just modify the template a little.
What processor do you have, BTW?
 
A9L, 19 lb injectors for now. I mainly want to install and be familiar with QH before I rebuild the engine.

255 pump, 19 lb injectors, and 90mm MAF. I'll tune that combo to get myself acquainted. Long term goal is a ~400 rwhp 347, using the same meter and 30-36 lb injectors.

I did the same with the tweecer. Some people like the a9p better because of slightly different ignition curves, but when you are tuning, it doesn't matter. I like the a9l better because it has more support at sites like tunexchange. I can answer a lot of the basic stuff, and eectuning or vristang can get the advanced stuff.
