1228747 C.A.T.S. vs TunerPro difference in ECM Mask / *.xdf file??????

Look carefully. The values are correct. The positions are not. Tunerpro 1st rpm row = Tunercat 1st column. With main VE table selected in TP parameter tree, press F2 to edit parameters. In General settings, change major order from row to column and click apply. Now the numbers across the two tables match. Question is which orientation is correct. Also notice that TP has rpm as 0 through 4800 while TC has rpm 400 through 5200. Again, which is correct.

Answer is simple. $4F disassembly matches TC. RPM values are listed as 400 through 5200. Using AKWH, 20 kPa entries should begin with 33.2% and increase to 58.59%.

Corrected TP definition (ver 1.1) is now in the 8747 info thread.

Just loaded up the new XDF file you made, awesome job!!! It never occurred to me that the values were the same, just located differently in the table, nice catch there! (I think I had been looking at it too long to see something so simple!! Lol) Anyways, I'm stoked to be able to use TunerPro for this now! Thank you so much!!

Awesome. Very cool. That is why I love this forum.

Oh that's sweet!

When I saw your engine build specs I got worried at the ECM/Mask you chose, but took a look at it and someone has done a really good job there... besides 1project2many. Has all the right stuff like $42 and a way better Fuel VE table. The only thing that worries me with a motor like that is there is no ESC Done patch for that mask. May experiance some big knock during the test? There is a hack though so may be able to reduce spark for test or?

When I was growing up, my Dad had a 1951 Cadillac convertible. It never even had a scratch put in it. He completely restored it while I was in college, and now somebody has it in a museum somewhere, I don't even know who he sold it to.

Ummm... that's cool but somewhat tragic as well. Stuff can usually be tracked down though if a person is truly interested.

Hey Guys,
This is the owner of the above mentioned 51 caddy; I've been working on fine tuning for the caddy with my copy of RT tuner CATS. First off, thanks for the help you gave Darren to get this tune on track, it's really coming along nicely. That said, I have a question for you RT tuner CATS guru's here. She's pulling very nicely all the way up to 4800K RPM then from 5000+ she starts to struggle... However the main fuel vs. VE stops at 4800 and the main spark advance table stops at 4400. How to i get this program to provide additional RPM to tune with? Is this even an option with this program? Ideally I would like this to go all the way up to 6200 or at least 6000. My cam, intake, and heads are all made for power in the 2000-6000 range. I looked all around this site and didn't see anything posted for this yet. Thanks in advance for your help to this issue.

It should use the last entry in 4800 RPM row for fuel.

D82A:  LD82A     LDAB    L001B      ; RPM/25, (ROW ARG)
D82C:            CMPB    #192       ; CK IF GT 4800 RPM
D82E:            BLS     LD832
 ;                                  ;  
D830:            LDAB    #192       ; USE 4800 RPM MAX FOR Lk UP
D832:  LD832     LDX     #$D37B     ; VE1 FUEL TABLE
D835:            JSR     LFB0B      ; 3d LK UP

Do you have a fuel pressure gauge or wide band O2 sensor to see if it is running out of fuel?
