That VE is a fantasy. It a table intentionally set up to be an eye-pleasing shape and there is no way in hell that VE came from any data collected during any kind of 'tuning' process.
No injector data? Only the flow rate's been changed from stock '00 LM7. Literally every piece of math the PCM does references the injector data in some way. It is the foundation everything else is built on. If that is wrong everything else will be wrong, I'm not looking at anything beyond that.
welp it changed on my screen. it did have a window that said post. its not there no more.
its a bore out iron lm7 block, aluminum is over rated in my opinion. if i had a 6.0 block i would bored it out to 6.2, at that time is all i had. but did build a 6. 0 to 6.2 but sold it for more than what i had in it. so i just kept my 5.7. the injectors i have are ev14 in A tbss intake. im kind new to this hptuners and tried to find more info on the injector data, trying to learn this stuff, i had decapped truck injectors like what matt has on sloppy mechanic site. i did have keith at pcmforless out of ohio do my first tune about 5 years ago, just trying to learn this stuff. thanks for any info.
You "had" decapped injectors or have decapped injectors? Ev14 isn't enough of a description for anyone to help you get data. Part number and manufacturer or at least a link to where you bought them. But it sounds like you probably have injectors that don't have enough data to properly tune. At least as a beginning tuner.
What map sensor are you using.. I don't recognize that offset scalar at all.Quote:

its to big really but all i have for the moment. i got the setting off sloppy mechanic, for the map.
i had a mail order tune done 5 years ago pcmforless out of ohio, keith did me a very good job. for the price. im not knocking him at all. just wanted to learn more. still learning. if i knew where to get the injector data from it would probably repair alot of my issues which is not much. i had changed my injectors from decapped to these ev14 non decapped. cause you cant for one and just not gonna do that for another.
Best advice i can give find a set of injectors that already has data available in GM Gen III format. Such as the 12576341, listed as 42lb with direct drop in Gen III data.
#1. That ve table is in no way correct. #2. Dont trust sloppy mechanics or use any of their advice, info, products.
yes i understand thatthe ve is not right, thats why im asking for the injector data, they was a used set of injectors that i got of market place, no data. as far as matt from sloppy mechanic i listen to him from time to time. as i listen to everyone. yes i did run decapped truck injector on my build for along time and had really no issues. out of them. i just switced to a tbss intake and couldnt get the truck injectors to work out. is why i went to the bosch longer injectors. trying o get the ve right but people telling me to get the right data for a ev14 injector i cant find the data.Quote:

You can order from a good reputable injector dealer that will send you the data you need with the new injectors. Or you can send yours off to someone who collects that data with an expensive machine and theyll send you the data and the injectors back.Quote:

Or if its a GEN4 tune file and needs the data changed over to a GEN3 with an excel file. Most of the data for almost every injector we deal with on here is in the "injector data repository" thread, BTW.
Also, EV14 is not an injector type or number, its the type of connector on the injector. For anyone on here to help you at all we need the actual part number on those injectors, which i believe was already mentioned in this thread....
This is what your injectors come back as from a quick google search... https://www.ebay.com/itm/144491252671 2001-2017 mustang injectors. Ford does not use the same injector data as GM and you cant just pull the "data" from their file. Also as mentioned before, these are probly not going to have any usable data to be found on here. Youll need to send them off and have data collected based on the PCM youre using.
What you paid for the mystery injectors plus what it would cost to have someone put them on a real test bench and generate all the characterization data is almost certainly more money than if you just dropped those in the trash and bought quality, universal injectors that come with all the data in the right format in the first place.
This is not anything to do with a flow bench, it's measuring how the injector reacts through the entire pulse width range. A flow bench can only test the flow rate, and that's only one of the four tables you need, and the least important of the four by far.
a bud thanks for the os i used the injector data and few other things in this thing. it really likes it. thanks man. and i want to thank the oter people trying to help too. im no expert for sure. guess thats why im in here lol. but anyway i want to thank you guys. she likes it.Quote:

This has been done and discussed before, unsure of what the final outcome was?

I was definitely not saying to just use that data without swapping injectors, i was recommending swapping to those i listed as they are similar to the ones you have with full data available, sorry if there was confusion!
No confusion here at all, was a good suggestion but I think the OP missed the point and just used the data which hasn’t achieved anything.
I do have ford data converted to gm. I can check tonight and see what i have. Quit listening to everybody, make a plan, stick with that plan. Dont listen to people working with shit parts and unknown mystery data.
You need to eliminate as many variables as possible and take it one step at a time, at this point the airflow models should be the only variable, PCM needs to accurately know how much fuel it is supplying so accurate airflow models can be derived, volumetric efficiency/MAF, this affects almost every calculation made be the PCM. If the VE is off because of bad injector data, everything down the line is skewed, you're cylinder airmass ends up incorrect, throws off the spark table, throws off the torque calculations which is used for transmission shift calculations, protection modes, etc...
Here is your correct data translated from calibrated success.
a thanks for this info. my truck is doing alot better.. im slow at this stuff but learning it. i really like the hptuners whys, its a learning curve for sure.Quote:

its a 3 bar map, map data is from a reliable source. its right for 3 bar. my afr is match to the tee. i had bought the map when i bought the intake. my map is a ac delco has a bunch numbers. its red, 0 261 230 185 this whats on the map its self. like i said its red.
12592525 acdelco

(816) germany
That is 100% incorrect for that map. Here is the correct values.
312.50
-11.25
Here is the stock zr1 file that uses that map.
ok thanks man
ok thanks man. you have been a huge help. truck is running so much better. the first time i had this pcm touched for the set up i have i had pcmforless do all my tuning. ans it was fine for long time, i had changed intakes and couldnt get the injectors to seal up right. i figured what the heak buy the mpvi3 and see what its about, its lil hard, but with help in these forums from you guys its been a learning curve for sure. again thanks
Should be ready for some ve tuning.
my afr gauge is matching the commanded setting. i was told if that happens that the ve is pretty much on point. or is this wrong info? seems like all the info i had gotten before was not right.
i could log a scan or two with these changes that you helped me with and let you see the data. might be a few days till i can get it to you. if you want. i appreciate the help. i usetoo deal with the carburetor cars. the turn of this or turn of distributor . it was easier back then. i do like these pcm cars and trucks take some learning for sure. i owned few camaros in my day. i had a 1969 it was a nice car i owned that one for ten years and then sold it like a dummy. thought id get another, i hadf a 1977. then i had a 1986, and a 1994.. ive always wanted this new type the 5th gen ones . i will be trying here in a few months to get one, alot of things are lining up for me to go out and find her. im trying to learn this stuff so when i do get one ill know what to do. some what that is
Post a log.
Attachment 161277 here is the tune with the injector data and a few others,Attachment 161276 here is the log from the scanner. seems to be running a lot better. thanks man for the help. the reason im doing this crap is that im getting knock in the scanner. id go weeks with out getting knock then i dont have the lapop hooked up then get a light, scan it says i have knock. i finally scan it and see it in the scan its at 4000 rpm. it say like 8 something not sure what that means here is the scan Attachment 161320 sorry brother. its the reason ive been changing everything. i changed the intake, the injectors, the tune, plugs wires, made sure all the exhaust gasket are tight in place, intake tight in place, made sure the exhaust itsnt rubbing or hitting the frame. thinking about going speed density call it done.
Looks a good amount lean. Id continue to work on ve
ok, ill do some tuning get back in here and post it up. will take awhile to do it
I would add 6% to the entire ve table for a start.
ok thanks
