Running a 454 TBI with a 4L60E, should be possilbe with BJLF/16196395 right?

[brianko]

Trying to get a 454 TBI running that's been installed with a 4L60E. Since there are no 454/4L60E calibrations I know of, I figured I should be able to transfer the engine parameters from a 454 calibration (BJKW) to a BJLF calibration. The engine runs with the stock BJLF calibration (not well, but it runs), but I get a no-start with the modified BJLF. I'm wondering if I'm missing something very simple here.

Cylinder volume? injector size?

Double checked all the important tables/scalars, including those.

I built a 5.7 bin out of a 454 manual bin one time, so it can be done, but its A LOT of work copying and pasting tables. You getting SES flash key on?

You are on the correct path by merging the two , I merged BJKW with BJYL to get my 454/700R4 $OD .bin .

VERY time consuming , best if you have multiple monitors and can open two instances of Tunerpro , copy / paste ........ Repeat .

No easy way about it .

This is exactly what I did, with TunerPro. Going back through and double-checking everything.

There is another way to do what you want. You have to find the beginning AND end of the HEX addresses of the trans or Engine calibrations.

This is what I do IF the addresses are known. I burn two PROMs. One for the 454 and other for 4L60-E. I copy the one prom into my Dataman S4. (It's a PROM programmer and editor. It has many features as well.) With the first PROM in the S-4 memory, I put the 2nd in the ZIF. I copy in the address range of the wanted data. Burn a PROM and you can upload you MERGED calibration into your Moates AutoPROM. Load it into your TP and your done.
A word of caution. I knew the exact addresses when I do this. If you miss or guess, you're in to deep. You might be able to locate the addresses in TP using the EDIT of each trans cal but this can take time as well.

This is an idea, might have to look at the XDF file and see if I can figure out where those addresses are...

No SES...

No SES...

Somewhere in the process of modifying the bin and burning the chip its getting corrupted. Maybe try only changing a few important constants and tables for your first bin, cylinder volume, injector flow rate, main timing tables and ve tables. It gets pretty crazy trying to change too much at once, especially if you have an old crappy laptop like mine that locks up momentarily when saving files lol.

Sounds like a plan. I'll try this approach first.

If my memory is wright? There are select bits to turn the calibration into a manual or auto and you don't have to edit all the auto cals.

As for the Merging of cals. I did this for 15 years and it worked very well. We had PC calibration tools that we could export selected cals to a csv file. We distributed or posted these cals for use. You select the csv files (like trans shift or trans diags, or engine spec or eng diags or cat mon, ect) and "import" them into the cal you must build to suite the needs of your vehicle. It would be nice to do this with TP BUT if someone was to use the wrong cal base or xdf to import into it would be really bad and TP would be blamed for bad things which were user error.

I give the 4L60E a life expectancy of about 5 minutes or 5 miles behind a 454.

Tell me about it. You tell people this and they just say "well that's what I have." You can only do so much.

Yea I understand that!

I come here with a heavy heart, head buried deep in my hands. O the despair! Life is just not worth living any longer!

I installed the EEPROM backwards on the adapter.

Yes, I said it. I made the number 1 rookie mistake we all have made but have never told anyone. There. I feel better now.

I have posted the modified bin up on the DIY-EFI site, link is here (http://www.diy-efi.org/files/gmecm/bin_lib/BJKW_with_4L60E.bin). I have also asked EagleMark to add it to the $0E bins section. I think it's important there are mirrors of these files, so I don't consider it a duplication of effort. I am still heartbroken over the loss of Monodax...

As for the bin itself, the guy I created this for reports that the truck runs absolutely fantastic. I don't think anyone recommends running a 4L60E behind a 454, but who am I to judge?

Thanks for all the assistance, learned a couple of new things along the way.

Yes, I'm still embarrassed...
