I haven't gotten this to work on my computer. If I gave my specs..could someone run the numbers for me?

Need a log where your logging injector ms doing a wot stomp from around 1500 rpms on up to redline...

don't have 1 with the convertor locked, I have a couple of runs at the track. Also not sure how to upload to this site.

Sorry to bump an old thread, but does anyone have a link or can email me the latest version of this cacl xls?
Another bump. I've been reading this and other injection timing threads for months and finally took a stab at coming up with numbers in the spreadsheet that make the timing graphs look how I think they should. I would *really* appreciate any comment on how they look. Engine is an all forged 6.2L w/ LPE GT9 cam, E-Force supercharger, long tube headers, if that helps.
id prob try the ect at all 90 and the 2000-2500rpm range i usually setup for little higher then cruise IPW where u already have 7-10ms maby halve it and ramp up from there as it will still be good on boost and not too raw for cruise
Thanks!! At least now I know I'm in the ballpark and interpreting the graphs correctly! These settings cleaned up the raw fuel smell at warm idle.
WOW, lots of reading!! Visiting this topic for a Gen4 6.2 completely stock with 7-8 psi from a Whipple, it looks like the boundary settings in the stock cal are completely opposite from ideal? They start with high numbers at low rpm and go lower with high rpm. Why in the world would GM crowd out their window for injection at high ipw by advancing the timing? More fuel requires more "boiling time" on the back of the intake valve? Attached are all of my settings as delivered from GM. I don't even know why they put in a makeup target adder with a straight 30 across the board. I'm guessing that is an allowed amount above/beyond the Boundary wall when absolutely necessary?
For my application, I put in 72 lb DW injectors (with their data) and was in the process of re-tuning the MAF and VVE, but decided to read up on this topic of injector timing. I can monitor AFR error when making changes, but just wanted a sense check before I do something so drastic as to completely invert the stock chart. That is a huge change!
boundary injection settings.PNG
leave the makeup at 30 or 25 as fueling seems to go odd if its too low (or did on mine anyway) can change the makeup min pulse to 0.2 for the bigger injectors, but yes change it all as it will make a big change from the factory setup and if ur doing fueling changes best to do this first so ur not redoing it after, do u have decent cam or just making fueling a little better ?
Engine and exhaust is bone stock (for now), just dialing in the cal. Started with Whipple?s cal which is maf only, which I?m changing, but they gave me GM 50 lb injectors and they were running at 100% so I put in the DW 72 lb to alleviate and provide room to grow. I don?t mind redoing fueling, I think I should just mount the laptop permanently in the truck. The mvpi already is!
yea u get to a point where it feels odd diving without a laptop to view, if u want the eoit better u could just change it to the stock early e38 settings where u have boundary all 520 then leave the ECT but then zero out the RPM and that would be better but not to far as u don't have overlap atm then u can adjust from there if u go cam or more in future
INJECTOR TIMING TOOL GEN IV - Black Charts-FRCv21.xlsx03-29-19 AEM coils.hptI have been following this thread and it is very detailed...too much for me to grasp fully use the spreadsheet. The community is very impressive. I have a 2015 ZL1 Camaro with a cam, 850cc injectors and bolt-ons since it was new. I had a bad raw fuel smell for a long time with no changes to injector timing. I did dial in the MAF curve and VVE table in addition to some work on the timing tables and I have always been pretty happy with the results with the exception of fuel smell, especially at idle.
I had a well known tuner dial my tune in further and he changed the injector timing by changing normal ECT only. He reduced the numbers of
245 245 245 245 245 245 200 155 155 110 110 110 110 110 110 110 110
to this
225 225 225 225 225 225 180 135 135 90 90 90 90 90 90 90 90
Now, the car seems to be a little more responsive in the lover RPM range and the fuel smell has been reduced but still noticeable.
Anyone know what the stock cam specs are for 2015 ZL1 Camaro with LSA engine? I have my cam card and it included specs I input into the spreadsheet. Can anyone help me dial this in better? Read through most of the pages of this thread and still not really getting it. Any help would be very much appreciated.
Post your Boundary numbers as well.
Found this on the specs. https://www.onallcylinders.com/2018/...ads-cam-specs/
198/216 with 122.5 lobe separation. No specs at .006" lift though.
My Boundry numbers are unchanged at 520 across all engine speeds
Hey Everyone. learned a pile with all of the information here that i spent all weekend reading through trying to fully understand this. i was wondering if i could get someones feed back on how i have this set up to make sure i am going down the right path. i flashed these setting in and went for a drive it feels a lot better. i had only had my maf tuned through cruising rpms up to as far as the narrow bands would read. during this drive i logged maf x stft and around 1800 rpm up to about 3000 rpm i was getting -10% fuel. i never had the chance to check a WOT pull vs wide band. my fuel smell dose not seem near as bad. at idle i have a little bit of fuel being pull, 2-3% for 1000-1800ish i didn't get any change in fueling. if someone would give me some feedback i would greatly appreciate it. i am not 100% sure if i have got my IPW right or not. Thanks in advance for anyone's input

I have a question regarding injector timing ECT normal with the range 245 245 245 245 245 245 200 155 155 110 110 110 110 110 110 110 110 as its seen in HPT for the E40, using one of the calculators available on the forum, pic attached injection event at idle happens while the inlet valve is open and the exhaust valve is closed. Should be no smell of fuel?
I have EfiLive, it doesn't have all the calibrations the HPT does for this PCM (I want to get HPT), the ones there thou are are the same except ECT normal, the values are double in Efilive, using the same calculator, the injection event happens on a closed inlet valve, exhaust valve open, would explain smell of fuel at idle?
Sorry if its come up before, i did search, i don't understand when normally all the calibrations are the same across both tuning suites, why except this one? And is one incorrect, or just the way they are displayed?
Could it be 245 245 245 245 245 245 200 155 155 110 110 110 110 110 110 110 110 are cam shaft degrees not crank degrees? so would need to double when entered into the calculator
hpt uses 720 deg of crank rotation nice and easy
