ive been beating my head against the wall all day time to ask for some help.....
11 cts v , had 650 hp lingenfelter "kit" with tune , no problems
swapped 2.55 for a 2.4 upper and added id1000's
no matter what i do the car is pig rich at idle, pegging stft @26%
what am i missing
heres the file and logid1000 pig rich.hptstill fat.hpl
Didn't check injector data itself, but at quick glance of tune and log it just looks like you need to adjust your MAF and VE models back in... Might want to re-enable ltft's to quickly rough things back in then go back to st's for fine tuning...
2010 Vette Stock Bottom LS3 - LS2 APS Twin Turbo Kit, Trick Flow Heads and Custom Cam - 12psi - 714rwhp and 820rwtq / 100hp Nitrous Shot starting at 3000 rpms - 948rwhp and 1044rwtq still on 93
2011 Vette Cam Only Internal Mod in stock LS3 -- YSI @ 18psi - 811rwhp on 93 / 926rwhp on E60 & 1008rwhp with a 50 shot of nitrous all through a 6L80

ive taken as much as 50% out of the maf table at idle to no avail. (4k and down) thats whats confusing me i havent touched the ve tables but correct me if im wrong , i dont think they would have changed much at idle. Im not disagreing with you im just failing to follow
i suspect its in the injector tables but lets address 1 thing at a time . i took 10 percent out of maf curve from 4k down with no change took that 10 pct out 4 more times and saw no change on the stft's should i log w ltft's on and see if it can attain target?
VE/MAF are air models that control fueling... Makes me wonder if the injector data was screwed with on the previous set? I just checked - as long as you have 1000s and not 1050s - it's right... Make sure your not chasing rich after flash and enable lt's...

This log looks to be taken when heat soaked. You have an injector Tip adder issue. Your PID list is so large that it is not polling all so info is not too usable. IE ambient is 32F and your timing never varies from zero.
The data in the tune is correct for id1ks as GHuggins mentioned. Did you have to use rail spacers to install these injectors (basically, are you sure they aren't 1050s)?
im embarrased........ there 1050's
anyone have a setup for the 1050's that they know works
specifically tip adder data?
or steer me in the right direction to rectify that table myself
thank you guys so much for the help thus far

Just pull the data from here and throw it in there. I'll bet lots of issues clear themselves right up lol
The fun part is that the id1050 flow rate exceeds the 127lb/hr limit for the stock ecu after 468kpa so you may need to scale it if you aren't boost referenced in order to do this properly.

new question.........what kind of timing above 4k on 93 octane iat's are around 126
anything over 12 and i get kr........
Get your fueling straight before you worry about timing.
first pull was @ 11.2 afr at time or kr
fattened it up to 10.1 with 10 degrees in it and im still getting kr
just less of it
im thinking i wasnt too lean @ 11.2 , am i wrong , do lsa's like to be off the chart rich?wave off.hplwave off 2 10 afr.hpl
wave off 1 was 11.2 afr
wave off 2 was 10.0 afr
where would be safe soft timing and where would you want afr
You have no WB so how do you know where the AFRs are? If you had one then 11.2 is more that rich enough and 11.5 is safe. If everything is PERFECT and you know other issues you can go to 11.8. This means the you know it 11.8 or lower on each bank and you know stoich quality of fuel. IE 2 WBs. Until you have the data you need you are shooting in the dark at a gas tank.
