twEECer newbie ?'s

[shotyme95]

I guess I am confused...

I need a MAF transfer file for a ford 80mm MAF. I am having a little problem with first time tuning. Any help would be appreciated.

Thanks;
Drew

Here ya go:

Just plug that into your calibration via the "Load MAF" button (which can be seen while viewing the MAF transfer function under the Function tab) and you should be set. The .maf file above matches the "accepted" corporate transfer function for the 80mm MAF used in the Mark VIII, et al.

Post here or shoot me an e-mail/PM if you have any more tuning Q's.

Thanks, Adam! I appreciate the hook up. Retry tomorrow, I'll let you know how I make out.

What kind of MAF is a ShoShop 80mm? Anybody?

SHO Shop 80mm MAF = Lincoln Mark VIII MAF, which uses the same transfer function as the file above.

Thanks. Now I can get tweaking.

Does anyone have MAF transfer numbers for a Pro-M 75mm? I know this MAF is technically = to SHO stock numbers, but how does the TwEECer know what the stock SHO MAF numbers are?

If you have an X2J, you just read the stock SHO MAF numbers from the EEC by clicking on the Ford oval in CalEdit (the Ford oval button loads the stock binary from the EEC). If you DON'T have an X2J, then you need to get an X2J binary and write that to your EEC.

Here's one:

I just ordered a RT Tweecer, and noticed in the computer list that it only had the X2J listed for MTX cars. Does this mean I need a X2J comp. to use this? Or can I use the file above to make my 90 computer essentially a X2J?

Thanks

No, the TwEECer, writes the latest MTX SHO code/calibration (i.e. the X2J) to the older EEC's such as B9B, B9B1, LOS etc., so as you say, it makes your pre-92 EEC run like an X2J. Thus you can use the TwEECer with any MTX SHO. The same goes for the V6 ATX SHO, where D4U1 is used for all V6 ATX. For the H3Zx owners, this means you don't have to buy a D4U1 EEC to get the better D4U1 programming - just write the D4U1 programming to the H3Zx EEC with the TwEECer.

Where did you order the TwEECer RT from?

"Stream Read Error"

Here ya go:

I loaded the file, and received a stream read error.

Any ideas?

tsk tsk, it's better to support a SHO vendor that sells the TwEECer - then you can get SHO-specific product support. We sell the RT only, and Midwest sells the base model (and RT).

In fact, we don't charge the shipping that the company does, so we are even cheaper.

WHOOPS!

Dont' worry Josh, when I buy mine this winter after cam install, you will hear from me..


BTW, I am going to get a measurement on those cams this weekend and email you back...

I didn't buy it. It was a gift from my father. He heard me talking about it and how nice it would be w/ the new motor, and I got a fowarded confirmation from him. If I bought it it would have been through you.

Can I use my home computer on one of these. I may buy it on the first if I don't need a laptop. Is it hard to program. I have a lincoln maf on the way and have true duals on it. I can download the file for the maf above but I'm used tp cars with pushrods, points, and carbs. Technically challanged when it comes to tuning something like this.

While you can technically use a desktop to program a TwEECer, it's not reccomended, as the J3 port connector is not designed for frequent use. If you are limited to a desktop, the functionality is then no better than an LPM, which has to be removed and mailed away (or change a chip) for re-programming.

As well, you won't be able to (easily) use the TwEECer datalogging functionality, which is the whole point of using the RT ...

I'd say spend $100 on a used laptop to get the full use of it. A working battery is not required, so any USB-enabled laptop with Win98 or better will work, just get an inexpensive inverter so you can plug the laptop charger into the cigarette lighter via the inverter.

If you are unsure of your ability, download the software and play with it first. It's on the TwEECer site, and free.

You need:
Borland Database Engine -- Required
RT130A9 -- Alpha release 9

If you find that tuning the car is beyond what you can do, there are many people around who can offer fee-based tuning services.

That is awsome! I need one just for the fun of playing with everything.
What I dont understand is the price. As far as I can tell the only major component of the Tweecer system is the calibration selection module, which also converts the medium from rj11 to USB.

The TwEECer is an adapter which connects to the J3 service port of a Ford EEC PCM

This, in itself is handy, but not nessicary as I see it. So long as I can get a base (stock) log file saved, I can tweak all I want (NA, NOS, etc) and save those induvidually. The other end, the software end, is free, so I am set there. Looks like all would need is a medium to connect the J3 port (looks like a 5.25" floppy drive connector) to a COM port on a computer. Perhaps this is more complicated than I am seeing it...? Or maybe a trip to the local Radio Shack is infact in order?

The TwEECer is a heck of a lot more than just the J3 adaptor connector (which, by the way, is more than just a floppy drive connector). It stores the programs you want to use, has the necessery electronic hardware to communicate with the EEC and your laptop, as well as providing a real-time interface with the EEC for datalogging purposes.

While it is possible to make your own LPM (and plans are on the web), it's not a trivial excercise. Even if you are successful, in the end, you only have a product that can store new programs for the EEC. This kit has to be dissasembled each time you want to write a new program, so you can put the EEPROM in a flash writer to write it. There are no roll-your-own internal EEC datalogging kits out there. The TwEECer software or any files created with the TwEECer will not work with a roll-your-own LPM, so the TwEECer software interface is out of the question.

IMHO, the value of the TwEECer lies in its ability to communicate with the EEC in real time for the internal EEC datalogging that it, and ONLY it, offers to the SHO. Other loggers, like the SnEEC, only log the EEC's external inputs/outputs, while the really useful stuff (load, MAF kg/hr, Lambse, KAM) are only available inside the EEC. Otherwise you'd stick with a cheaper commercial or roll-your-own LPM and learn how to program it.

However, if it takes a trip to Radio Shack for you to see you can't duplicate it, go ahead
