Hi everyone,
Hope the new year is going well.
So I've taken some time to try and figure some things out on my own and would like some reassurance I'm not going to damage anything.
Truck was originally a V6, Harris tuned a chip for me and I recently put on a summit tbi head carb intake and adapted to TBI. 1102 Summit Cam, Flowmaster Y pipe/converter, 3" single exhaust and AEM intake. 3.73 to 4.11 gears. 265/75-16 Cooper Discoverer STT
So I've been datalogging some just to learn and play with all the incredibly helpful spreadsheets I've found on here. I'm very handy on excel so I appreciate something about this learning process I can follow. So now it's time to start dialing things in.
Currently the truck will stall out and restart fine until its warmed up, using 78.8 lb/hr, 4DA with EGR off and WBO2 settings used. It does run good when on throttle with the exception of an occasional backfire/hickup usually when coming off cruise. According to the WBO2 I'm not running lean. So here's what I've burnt to do my initial chip that I'll data log with that I will be using for the tables. All the WBO2 flags and tables listed in tunerpro (Code 32 NS, Linear EGR S, USe L4783 S, Backpressure EGR NS, EGR off in Open Loop NS, EGR off at idle NS) Zeroed out Desired EGR vs RPM vs Vacuum and EGR Fuel Reduction vs RPM vs Vacuum. In addition I changed fuel to 78.8v lb/hr (measured fuel pressure at 18-19 psi and using a trusted flow at 14.7 psi I converted my flow) Smoothed out my VE tables using 0.7, set initial timing to 4 degrees at distributor and in bin, Maxed out following settings: min temp for dcfo, min temp for pe, min speed for egr, temp for egr on. I have read in EagleMark's tutorial http://www.gearhead-efi.com/Fuel-Inj...-data-Tutorial! to shut off air pump and highway lean mode. Does my bin have those? I searched using the function and also scrolling and didn't find anything.
My plan, warm up the truck. Start recording and do some highway driving trying to vary load and tps? I live in rural Kansas so no on ramps or anything but I can find some hills. I plan to get the info, use history tables and spreadsheets to fine tune. When I get everything dialed in with these settings by changing VE tables what do I need to return to normal? My intake manifold does not have EGR so it will stay off but if I get it dialed in I will likely plug WBO2 port and remove gauge.
Also, for the 4.11 gears what is the easiest way to change my shift tables and pressures? I did put a shift kit and corvette servo in years back but it doesn't shift very firm.
Thanks! I have learned a ton but feel like I've got a long long ways to go.
PS: Sorry for the lengthy post
