Your question is not very clear. Are you saying you cant find the VE table, are you saying that you see the VE table but TunerPro wont highlight the active cell, or are you saying all the cells show 0, and what are you talking about when you are saying it shows 65...it shows 65 where?

no problem! What version of TunerPro are you using, and what version are you running on the TranslatorPro unit itself?

In TunerPro, there is a button right next to the DVFM buttons at the top, it looks like a graph with a red arrow, it will say "Enable/Disable ALDL Data Tracing" if you put your mouse on it. If you click that, it should highlight your current cell in the VE table.

i think tracking is active because the Dashboard is working.
hm dont what version my maft is.. it think it's 5.10
TunerProRT is in Version 4.13
But is it normal that the MAFT device show nothing on its display for CEL?

Having ALDL connected and having tracing enabled are two different things. Tracing is the function that will highlight your current cell whether it be in the VE table or in the high/mid/low user tunes

Your MAFT should show a number for CEL with the engine running, try updating the MAFT to 5.22 and see if that helps. Unfortunately http://fullthrottletech.com/ is down right now, but that is where all the files will be. It should be back up within a day or two.

okay i will try to update the firmware.
is it possible that something is wrong with my wiring? .. the engine runs great in speed density mode
strange thing is that something there is a value on CEL on the maft.. but thats very rare

I have never really found that pid to be useful for anything therefore I never really paid any attention to it. I will take a look at mine and see what kind of readings it gives me next time i drive my car.

OK i took a look at the CEL pid... it is very erratic and reads 0 most of the time, this sounds exactly like yours. I wouldn't bother using it, just open the VE table and enable ALDL tracing and adjusting the ve table is made simple.

My Pro Version is 5.27. Its brand new ;)

okay i think will test if the VE Table Tracing on the PC is working.
It think i was just to stupid to see the correct button in tuner pro ;)
I got a other question. Can the Pro or Tunerpro show me the Injector Duty?

No it can't, since it doesn't have direct control over the injectors. You can look at the frequency output though, which is the airflow signal it is relaying to the stock computer. When did that version come out, do you have any idea what kind of updates are on it? I thought 5.22 was the latest :(

no sorry. i received it on friday. and i was sent to germany in the february... yes, very long shipping time :D
ALDL tracing is now working, but it is normal that always four Cells are highlightet?
My friend got a SIMTEK ECU in his subaru and its showing a crosshair on the cell exactily where it is running.

The MAFT uses smoothing, and since you are rarely in one particular cell it highlights all the cells that the current value is being influenced or affected by. Basically the cells that the yellow highlight is hovering over are the cells influencing your tune at that particular point, and the tune isn't going to be the value of any one of those cells, but more of an average of all of them. It could probably be more precise, but with the abilities of the inexpensive maft pro and rather simple nature of tunerpro, its just not going to happen.
