is anyone able to share what these 3 CTSV settings are??

Set proportional airflow back to stock, optionally use the settings from a CTSV (they are pretty good from the factory). Integral still...

great thanks!!

staich was scaled using a factor of 2.18 due to injector size.

thanks!!

is there a difference between setting this " Go to Idle, Airflow, Effective Area, and change the Max Fail" to 8191 instead of 200 like 07GTS suggested?

i lowered all the timing tables...

thanks!! I'm using the 2 Bar OS from HPT that is SD only and doesn't use a MAF, or at least that was my understanding. so there are still things that need to be cancelled out for that? HPT doesn't...

Hello,

Hi. Thank you for the help!!

i changed those settings and still cant get it to idle

ive tried increasing the idle from 900 to 1150, just to try to get...

is this what you are referring to?
the injector offset selection? change form vacuum to MAP?

Hello,

i recently installed a return fuel system with an A1000 pump and 1250cc injectors.
i currently can not get truck to idle. it was running and idling fine before with no issues.
we ran out...

yes thank you, that is what we were able to figure out as well.

ok i scaled the table they gave me for the pressure delta to be kpa.
however they are showing that the injectors are 131lb @ 58psi, where the sheet that came with them shows they are 138lb @58 psi....

attached is the excel sheet they sent me this morning with all the injector data. :D :D
looks pretty helpful, but i didn't bring my tuning laptop with me to work today. :(

thank you very much for your help, i truly appreciate it.

i emailed them asking for the more data and questions. ill be giving them a call on monday.

so i really have 2 points on the chart. 58psi or 400 delta and 43.5 psi or 300 delta. correct?

this is a 2007 standard cab short bed silverado. :D
so yes everything else is still there.
i call it fakenews since its loud has a big intercooler in the front of it, but goes nowhere fast. LOL

thanks!!
no it does not need that much fueling. those are just what he bought because he wants to run E85 mixed. so he went with the bigger injectors in order to flow it.
i have never dealt with...

so here's how i did the injector flow rate table, hopefully that's the correct way.

took 138.56 (given from the injector calculator) and divided it by the 2.18, which gives 63.559.
it let me put...

awesome thank you.

yes its currently a returnless system with the stock rails.
we were hoping to get by for a couple months with just the injectors before we went fuel cell and a return system....

for the ivt terms, i would need to do both tables correct?
i would multiply them by 25%?

for stoich i would be multiplying by 2.5, i think?

great thank you!!

i applied the 2 bar OS and transposed my last vve map into the ve tables.

Thank you guys very much!!
The truck is massively better now.

I'll install the new injectors in the morning.
Question does the 2 bar OS allow for higher rate injectors?
So I wouldn't need...

great thank you!!
ill turn those off as well.

yes thank you.
in the logs i was seeing that i was getting up to like 3g on the airmass.
i figured since i had to scale up the VVE table that i also needed to scale up the spark table. since i was...

Yes the cats are removed.
