Hi all! I've jumped in and swapped out my carburetor for a TBI unit on my jeep and looking to take the next steps and tune it and wow there is a lot of information out there which at times seems overwhelming, but want to learn and hope to help others with what I learn based on my application. The stock BCC is AMUR (GM Van 350 TBI with 700r4 transmission), but since I don't have the equipment to reprogram the stock chip and it is for an automatic transmission I figured I would just start with something from a manual transmission. There was lots of good info here from this site and ultimately will start with the ARHT BIN: http://www.gearhead-efi.com/Fuel-Inj...Information-42

TBI Specifics

XDF: $42-1227747-V5.9.3
Couldn't get the O2 sensor so replaced the O2 sensor with a three wire heated O2 sensor based on reading forum posts about getting to closed loop sooner and staying in closed loop at idle
Couldn't get the knock sensor and currently have one for a 1987 GM 5.7L TBI, but the diameter is larger than anything I have in the AMC block so haven't figured out how I'm going to remedy that right now, but the show will go on....
Jeep Details and mods
1978 CJ5
AMC 360(5.9L)
No EGR
T-150 3 speed manual transmission
No Air Conditioning
No Smog Pump
No VSS yet
E2000 Fuel Pump which runs at 12psi
No Vacuum Advance and Mechanical Advance is locked
Initial Timing: 0* BTDC. The jeep has started with no issue so I believe the timing is controlled by the computer
Some questions I have:
1) Since I haven't figured out how to make a knock sensor work should I turn that flag off?
2) What flags should be turned off or initial conditions should I do prior to collecting data?
Collecting data:
I like the way that EagleMark laid out collecting data in this link: http://www.gearhead-efi.com/Fuel-Inj...ate-10-24-2011and I plan to do the same with the expectation I will analyze the data and work to get the Main VE table fixed as an initial step.
I also found useful info here in which dave w made an excel spreadsheet to help with fixing the VE tables: http://www.gearhead-efi.com/Fuel-Inj...r-Spread-Sheet
