1993 BDJZ 1616825 $OD Log Data for imput!

[bonesetter79]

This is my 1983 GMC Jimmy with a 1993 Chevrolet Suburban TBI 5.7. It's a bone stock bottom end that I re-rung, stock cam, GM Perf-Parts Vortec heads, Elelbrock EPS square bore Vortec intake with no EGR, Transdapt TBI adapter, oem ignition, Ceracoated long tube headers, full exhaust with 2 flow monster 40 series mufflers. I've had the Injectors serviced and customized the TB press/reg spring. The Aeromotive fuel pump is showing +/- 18psi line pressure at the TB. I don't have a WBO2 only a heated O2 sensor after the long tube header collector. I've tuned out the EGR and executed a -0.020 to the MAP Difference AE Multiplier vs. RPM.

The BIN:
BDJZ 93 C-K Truck 5.7TBI 4l60e with 3.73 or 3.42 gears.bin
The XDF:
Advanced $0D TP5 v251.xdf

I've tried many other combinations and this is the best I can get it to run without building custom history tables. Any input would be greatly appreciated!! I've already learned so much from posts on this Forum! I figured that I should contribute something myself! I'm just pumped that it runs at this point LOL!

Likely BDJZ is definition $E6: https://www.gearhead-efi.com/Fuel-In...Information-E6

I couldn't get it to run worth a shit till I tried the $OD mask... Plus theres been a lot more work done on it versus the $E6.

Also, this is not "Log Data Input"...

Agreed! But it runs so I didn't adjust anything..

The attached Vortec BJLH .bin file might be helpful, it has the timing table from a 1998 L31 Vortec 5.7 liter.

I'm not sure how it could help? The timing on the $OD mask that I am using is close. Maybe a little direction on a few history tables to build? Then I'd have a better idea on where to tweak the xdf. I like the $E6 tables better that the $OD but I couldn't get it to run worth a shit with that mask.

[bonesetter79]

And I also have no idea how to tweak the existing timing that's negative! Lol

Which timing requires being tweaked? Usually a Copy / Paste using the difference tool.

That's a great question! Did you view the log?

Yes, using A217 $0D TP5 v250.adx, but has weirdness I'm unable to figure out. Please see attached .pdf for details.

It would be nice to do real time tuning with an Ostrich 2.0 Emulator. https://shop.moates.net/products/ost...-the-new-breed
