I've been researching a few topic for the past couple of weeks, but Haven't found complete answers. Was wondering if anybody can help:

I'm debating which software to go with Tunerpro RT or TunerCat. I have a 7747 ECM, so tunercat should work for me to start out (& buy if I like it). I've been comparing to tunerpro and I've noticed some differences...Tunercat has a table for my ECM labeled "speed / RPM ratio limits vs. gear" .What the heck is this? and why don't I see anything similiar in tunerpro?

Tunerpro has me kinda rattled with the whole definition file thing. I could only find one definition file that actually worked. All of the 7747 ".ecu" files from the diy-efi site wouldn't work. I got wierd stuff in the 3 boxes in tunerpro. I found one that worked, but it was somebody's upload, and I don't really trust it. I trust the tunercat definition file, because it's from tunecat and it's said to work for 7747's. Has anybody else had problems loading tunerpro definition files?

Thanks.

I use both Tunerpro and tunercat, they complete eachother fine. Tunercat has nice graphics but tunerpro is more advanced and has alot more features, compare up to 4bins, inbuild editor and so on....

Not what you wanted to hear, but I use them both and dont want to choose between them...

I wouldn't worry about the ecu file.
Even the popular 8D has a few errors.
Somebody would help you.
A little tedious, but I'm sure Mangus or someone would walk you step by step through adding stuff to a ecu file.
On the errors, did you pick the right mask?.

Although I know there are people on here with correct files.

The gear thng sounds like a shift light table.

It's not a shift light table because There's one of those in tunercat too. I'm not too concerned, as long as it's not some sort of speed limiter. I haven't been able to find anything saying for sure how to change a speed limiter, just that it can be changed in the PROM if you're tuning. The main stuff like VE tables and Spark tables look the same in both programs.

Might be for the down shift solenoid on a T400.

Look at a hack for your bin. It will probably be commented.
