Ok here we go I have installed BDE and RT130A9 (1.30 version) and tweecer too my laptop ,so now what I have to do - When I plug tweecer on J3 port on EEC I have to plug USB on tweecer and Laptop right - Next what I have to do, I gonna use 94-95 GT Vert 5 speed OEM binaries with changing What is first what I have to do AND HOW - Can I drive and have tweecer turned ON on laptop (digital/dashbord) ? Please if you know enithing tell me word by word because all those manuals are short and 98% are for 1.20 version and I wanna use 1.30 Today I plugged tweecer (I make a few changes ) but car couldn't start ( fuel pump work non-stop) I had cleaned J3 ports long time ago so there is no grease on them Zero Signal I know you are good in This TwEECer stuff please help me out before I get crazy
That means you are on a blank calibration (doesn't exist yet). To give yourself a basic TwEECer tune, set the switch to position 1, read the EEC, and write to TwEECer. This will give you an identical calibration to stock. You might want to create a datalogging payload and write it along with the stock calibration, so that you can watch the car run and start to get a feel for what goes on. If your car is basically running okay right now, I would start *slowly* with modifying the calibration. If you are having surging problems, you might want to jump pretty quickly over to the J4J1 calibration, it's a better starting point in that situation. Dave
If the fuel pump is running non-stop, your J3 isn't clean enough. Grease is not the problem, it's the silicone coating on the PCB. I had also thought I had mine clean enough, but no. Here's what I had to do to get mine clean- http://tweecer.oplnk.net/viewtopic.php?t=2877 You can test the connection by trying to do a 'READ EEC' in Caledit. If your scalars and functions have garbled data like out of range values (idle rpm-8342 or CID=452.4 or whatever) then your J3 isn't clean enough. First thing I'd do is verify that your J3 is clean and the tweecer is communicating with the EEC correctly. Step by step- Plug in Tweecer to EEC with EEC removed. Tape on tweecer with tape - I also used a thin piece of cardboard (like a cereal box) as a spacer between the EEC and tweecer. Plug in USB and switch box cables and tape them down also. Install EEC Plug in switch box (full counter clockwise is #1 and full clockwise is #5) #5 is stock program or tweecer off. Turn switch to #1 Turn on laptop, and load windows Load Caledit Plug in USB cable to laptop Turn key to ON (do not start) Wait for USB driver to load (about 5 sec) -you should have a connection now- if fuel pump runs non-stop, J3 is not clean enough. you can try the read eec thing now. If you have verified the comms, then I'd try to read the EEC and copy it to another switch position and see if the car will run off of it. get comms between the laptop and tweecer with switch in pos #1 *read eec - this copys the program in the EEC into caledit *then click 'write tweecer' - this writes the loaded program into the tweecer in whatever switch position it's currently on *wait for caledit to finish writing *turn off key *turn on key *start car and verify that it runs as it did without the tweecer if so, then good next try changing something like the idle rpm get comms between the laptop and tweecer with switch in pos #2 *read eec - this copys the program in the EEC into caledit *change the idle rpm scalar to something like 1200 *then click 'write tweecer' - this writes the loaded program into the tweecer in whatever switch position it's currently on (this time #2) *wait for caledit to finish writing *turn off key *turn switch to pos #1 *turn on key *start car and verify that it runs as it did without the tweecer *turn switch to pos #2 *verify that the idle increased if so, then it is safe to say that you have a working tweecer setup and you can begin to make your changes. With your mods, I'd start with a J4J1 calibration rather than the T4MO or whatever. Rick
So rockin rick what you sayin is "read eec - this copys the program in the EEC into caledit *change the idle rpm scalar to something like 1200 *then click 'write tweecer' - this writes the loaded program into the tweecer in whatever switch position it's currently on (this time #2) *wait for caledit to finish writing *turn off key *turn switch to pos #1" So everytime I have to "read EEC" into Caledit than do some changes and write Tweecer on one position on switch , than turn ignition key off ,then switch to pos #1 ,start car see if enything wrong than switch to other pos where I put changes , it this right Next thing what is better version to run 1.20 or 1.30 Next thing is why is there two place with OEM binaries 1st one is from "calibration files / Input files" (first one is on 1.30 version ,second one on 1.20 ) 2nd one is "strategy" I can find my or cobra OEM binaries on "calibration files/Input files" but on "strategy " I can't , on Strategy I can find only CBAZA or ZAO What I have to put if I gonna use J4J1 calibration And do I have to "read EEC" if I gonna use J4J1 calibration And last two questions for now is (most stupidest) Do I have to keep USB cable connected on Tweecer or just Tweecer on EEC when I driving car Can I drive car with ALL hook up (tweecer and Laptop and watch on "CalCon Dashboard/Digital" screen
No - the list I gave you was to verify that the tweecer and the eec were working correctly. You shouldn't ever need to 'read eec'. What I did is downloaded the J4J1 calibration from the tweecer web site. Then loaded it off of my hard drive into caledit and did my changes. Then click 'write tweecer'. And saved the new calibration onto my hard drive with the tweecer. Then next time I load that saved file in caledit and make changes. Then 'write tweecer' and save to hard drive. Also, the switch only tells the tweecer which slot to write the currently loaded calibration into. The tweecer can hold 4 different calibrations at any given time. The switch selects which one the tweecer will give to the EEC. You can turn the switch anytime the car is running and the new calibration will take effect right then. You have to have previously did a write tweecer with 4 (or less) calibrations before switching while driving. For example, you could write the same calibration to all 4 positions, but only change the idle rpm between them, say have 1 be 700, 2 be 750, 3 be 800, and 4 be 850. Then, while the car is running, you could switch between them and the idle should change. You can then tell how low you can get your car to idle. I've only used 1.20 - there are problems with both. 1.30 has dropouts during datalogging, I find that unacceptable. The strategy is the processor family - ours is CBAZA. Several different calibrations use this strategy. They are all 5 calibrations used in 94-95 GT and cobras. They are T4M0, J4J1, ZA0, WH40, U4P0. Specifically, the EEC has a program that it runs. All CBAZA EEC-IV's run that same program. BUT the calibration data is different. That same program looks up different data. Don't confuse the program with the calibration (what you change). No, that won't work. You don't need the USB cable hooked up to the laptop at all times. Only when writing to the tweecer and when datalogging. You can drive with the laptop connected. To get calcon to display real time data, you must be datalogging. Rick
MORE- It's completely possible to use only one switch position the entire time that you are using the tweecer. The tweecer has to connected to the EEC at all times, but the usb cable doesn't HAVE to be. It's entirely possible to only connect the usb to the laptop once, then drive the car with the new calibration forever without having to connect the usb again. Of course, this requires that you are happy with the calibration that you wrote to the tweecer. Rick
Rick you are the man How long I can drive with calcon to display real time WITH datalogging, I mean how long I can datalogging Now I have to fix damn laptop because guy who sold me this one USB port doesnt works, won't reconize any USB stuff when I plugged USB cable ,I was tryin with USB 2 card but same thing
After looking at my datalogs, I'm guessing ROUGHLY 1/2 meg per minute. So at that rate, 5.1 GB (of free space) would hold 175 hours. Rick
Ernie In case you don't know, the playback thing in CalCon is only one method of looking at data. The file opens in Excell by default and you can manipulate that data many ways with Excell. LogAnalyst is a nice program for crunching datalogs and can be dl'ed for free from the Tweecer site. EEC Analyzer is another program for analyzing datalogs and it can take info from a datalog and use it to make recommendations for changes which is a very nice feature. Later Grady
Ok guys, last night I was awake until 12AM /4 hrs I was seating in my Stang and I figure out Old version 1.20 doesn't works for some reason (every file I open is empty or so) So I tryed with 1.30 version and it works , I open Calcon too and drive about 10 min COOL BUT there is some things that I don't know yet and some things doesn't work yet -On CalEdit 1.30 under "Utilities" For what use that area "copy from" What is that stuff under "Functions" What is under "Tables" -Next is Varbiale for RT Datalog Payload I checked this one and looks like when I checked this 16 or what ever ,on Calcon digital/dashboard show up BUT not all - I use bank count 2 RIGHT For what is that on bottom "Update only" and "Data logging" -Next under Tables What I have to adjust there and can I adjust there anyway -Next under Functions , do I and can I adjust anything on bottom NOW about CalCon (new version 1.0) What I can do under Plotting and where supposed to be checked (3 boxes)under plot on botton And last one under Setup What I supposed to put under -MAF Gauge Max Value -Speedometer Correction Multiplier -EVP Signal Transfet -DATAQ 4 Channel Logger -Samples -Playback Rate And one more thing How I can get WHOLE Digital / Dashboard to works ,because I can get just half like ECT ,rpms,mph,WOT,MAF kg/hr,Load,Advance,Hego1 and 2, and battery volts, BUT I can't get work A/F ratio ,Load %, MAP/BAP,Injector DC ect
I don't know most of this as it seems 1.30 specific. I think that you may need to completey unistall 1.30 and the USB drivers and reinstall 1.20 to get it to work right - not sure! IIRC- 1.20 and 1.30 calibrations are not compatabile with each other. The samples, you can set it to whatever you want. I set mine really high, (like 250,000) so it continues to log no matter how long I drive. If it's too low, it will automatically stop after logging that many (at least w/ 1.20) The playback rate - only matters while playing back data later. Sometimes I slow it down (like 400) so I can see the changes better, and sometimes I speed it up (like 50) to get a general overview. Don't think it matters while datalogging. You can't. Only the 16 (max) things you choose to add to your payload will log and display. There is only 1 payload in the tweecer. All calibrations will use that. You don't need to re-write it every time you write a calibration. Only the latest written payload will be used - even on calibrations that had different, previous payloads written. The A/F ratio won't work unless you have a wideband connected to the EEC (highly recommended). You may also not get a few others to work right, as the software is buggy (beta or alpha) and the company (Slower Traffic Keep Right) doesn't seem to care. This book is informative on how the EEC makes it decisions (it's strategy) on what to do. - http://www.amazon.com/exec/obidos/A...55027/sr=11-1/ref=sr_11_1/103-7704625-3957448 Rick
looks like a good book, but it goes up to 1993. even though it is still a EEC-IV, ours is a little different that the ones the book covers. I wonder how many of the differences would just mislead us 94/95 guys?
The engine controls are the exact same. The differences between a fox engine and a 94-95 have nothing to do with the EEC. It operates the exact same. This book was really good about teaching the concepts of fuel injection, as well as how each sensor works exactly. I had no idea why the fuel pressure regulator needed a vacuum source for the longest time. That book enlightened me. Scott
perhaps i am not following you. they are both eec-iv, but the program the eec runs changed significantly between 93 and 94. check this out for details: http://fordfuelinjection.com/files/A9L_vs_T4M0_showdown.doc - chris
Hey guys I know its nice to talk aboit EFI ,but please let's help me out here than we will talk about fuel injection
