I made 2 test hits today and it is getting better just the original start so I will have to wait till tomorrow for that again. But that is what I am looking for, for the parameters. I normally just...

Ty, very detailed response, completely understand. I have just been using the excel sheet Dave made for the wbo2 and copy and paste. I think I remember a few years ago dave saying to smooth out the...

Both the open and closed SA are 26 degrees from low map to 60map up to the 1000 rpm mark, then the 65 map is 25 degrees. Both Idle and regular BLM are set to 128 minimum right now. here is idle VE...

alright tested and with no modification to the o2 or idle except 800rpm drive and 900rpm park, it still does it in park after warmed up. Acts a little different though. put in park idles at wbo2 12.3...

I have tried a few things, played with air% at idle, o2 sensor rich/lean, and a few other idle settings but still get this surge, something changes while it is idling. when I put it in park it is at...

So I made a few changed, proportional gains unstable and stable and lowered. I also took out the under and over idle rpm and made it zero's. Drove the truck, still see a slight surge at .7v tps at...

ok so I mostly have this tune figured out, 2 things I really need to figure out though.
1- the speed is off by 3-5mph, so when I take off it is 0 till I hit 3-5 mph, is there any way to change...

thanks Dave and Brian.
Yes I have had to up the AE which made considerable difference and also PE a little. I have worked and reworked the VE tables as I make changes. I test, datalog run the log...

besides the injector flow being changed when you up the psi or put in bigger injectors is there any other perameters or tables that need to be changed

so after reading about tbi injectors and their vast difference in flow rates for the same injector size and thinking about the 65# injectors I have. even though the place I bought them said the flow...

daily driver in my case. Well my truck see's maybe 5-6000 miles a year. 90% is highway miles and the motor is 2yrs old. ultimately this will be a toy almost at that point maybe 1 more year. Then a...

Thanks for all the info, guess there is no spring for the 20-26 range, there used to be a gold one that would do 16-26 from what I read but have not seen one. So I guess my options are the big block...

not sure how true their test is but here is...

ebay search "tbi cop car injector". 17084327 - Yellow / Brown - 5.7L / 350 Police Package 76 Lbs/ Hr @ 12.5 PSI, 83 Lbs/Hr @ 15 PSI

copcar injectors are 83lb @ 15psi. I have mine set at 22 when it is cooler our and goes down to almost 20 when hot, I live in Fl.
So with all the different places/excel sheets to calculate I should...

Dave a few questions about the wbo2 spreadsheet. I changed all the openloop to closed and then configured from there, am I incorrect in doing that, I read in a post about the sheet to do this. Second...

I have electric fans which are on all the time so yes it does take a little bit to warm up, once I get the tune situated I plan on hooking the fans to the computer. I am forcing open look to get this...

r42lts plugs in and new knock sensor they say tq is 14 so I did just under that so it is not too sensitive from what I was reading. Took it for a drive and still getting alot of these knock counts...

PlayinWithTBI I saw those last night on amazon but figured the plugs were for a 350 and any parts store would have them. I found them 2 stores north so about 30 minutes and I have to go up to tampa...

got the knock sensor today will hopefully install tonight once the truck cools off. I stopped at 2 parts stored and they didn't have the acdelco r42lts plugs so I will probably order them tonight....

I am running since I put in my msd 6AL a acdelco 41-993(19256067) iridium plug. I had acdelco rapidfires before that #14's. I had no knock issue when I was running the 7747 computer with these plugs....

Dave thanks for the input. I am using the excel wbo2 sheet. I have been trying to read as much as I can and search as much as I can before I post because there is alot of information on this site, if...

Thanks dave. I have seen the thread you linked. with the 7747 I started with the vortec bin you posted and changed the timing table to fit my motor, I had it running without knocks. So when I swapped...

ok slowly getting some of these fake knocks down, I say fake cause they do not pull timing. Is there a parameter in the data log that tells you if you are on open throttle or closed throttle SA...

I am using tunerpro rt, been using the forum for years and modifying bins when it was 7747 computer and had it running pretty good. But since I went to the 7427 I have been in the learning curve and...
