Just put longtubes on my Silverado. :D

Only had front o2 bungs. Now I am getting a P0036 and P0056 for both rear o2's. What OBDII options whould be on and off in the diablo? Its a U7192 that still has the o2 options. I have everything under o2 turned off now(read to do that on another forum) but ...

Read before your first post. LTFT's are between ZERO and ONE point FIVE SIX...

I bought it used on ebay for 120. Im fixing to purchase EFILive, but i had to have something to tide me over. It is a 2.05 revision... yea no data logging for me.

I bought mine on EBAY for $120 haha. Its a 7192 with a 2.xx. Update available for me? Also what is the difference in the performance tune? Is it more aggressive? Im kinda iffy on this one because im fixing to go with longtubes and I dont want to have a CE light on for o2's... Might be worth it if it ...

Just tuned it after that trip. On the way back LTFT's were between 0 and 1.56. Cruise on at 2000RPM +/- 10 by the data. I dropped the injector slope down to +1%, upped the fuel trims a good bit(somewhere in the +15-18 range), and upped the timing to +11. Disconnected the battery for a minute and ...

Well I cant do logging with mine... guess its an old version. After a 30 mile cruise and then a 10 mile @ 2000-2100rpm. The ltft's are 4.25 and 4.79. So I take it it needs a bit more fuel, correct? Running a hair lean and compensating by adding that much? Suggestions to bring it down toward zero?

Mine also says something like 2.02ish and I couldnt find any logging stuff? Whats the deal?

I just put 1.8 rollers on a 2000 Silverado 4.8. Made it sound a bit more choppy and gave a little more power, but I wont be buying any for my truck. Wasnt worth the time or money IMO. The stock rockers are really not bad at all. If I were you I would go with a set of longtubes and an intake if you ...

Just tuned the 7192 on my 06 4.8 and all I can say is WOW. The gain was more than I expected. I havent been on any long drives so I havent been able to dial in the fuel trims, but right off the bat this thing came alive. I also figured out that in no way, shape, form, or fashion does the performance ...
