Evening all!
From the humble beginnings of my '93 K1500 Suburban engine swap, I have been learning allot from those in the know on this forum. DaveW, Fast355, 1Project2Many, and several others.
The project has been frustrating to say the least, but now the struggle has got me to a point where I like driving this truck again.
The last swing at it made a huge difference in drivability!
Now I would like some of the more experienced TBI folks to nudge, point, suggest where I can continue to make improvements.
Baseline Info:
1993 K1500 Suburban
350 SBC Crate Engine '882 heads (76cc)
Cam: Lift .383 in/.401 ex Dur @.050 In 194 Ex 202 112 LSA - nothing hot
Stock Throttle body on a Edelbrock Performer Dual plan adapter and 1" spacer.
3.42 gears
4L60E
BJLH .bin with modified timing and fuel tables $OD mask
Timing Table is a modified/smoothed Iron Head LT1 with most of the Open Throttle VE vs MAP vs RPM table reduced by 4%!
Last run this evening I swapped the '8625 for a '7427 pcm with the same file and it made a big difference. That is the log file attached here.
Currently looking for good highway drive ability with on ramp go.
attached .zip file is my current .bin and last .xdl
Any comments will be appreciated on the timing and ve tables, and any of the other tables that should be tweaked.
Thanks,
Louis
