What are you guys doing for this data , shown, setting up some fic1200, and there really isnt any info on here for the changes that need to be made for these options, just seeing what other tuners are doing thanks!

correctly adjusting the start up base of the inj pw [34000] is crucial -
get that right or kill a $200 set of plugs, or worse...
injector dynamics gives me a good starting point. fic not so much
the fa limits [34200 and 34202] are only changed if the stoich of the fuel you will be running has been changed
whats a good formula for startup is there a datalog setup you recommend?Originally Posted by LilSick
i have no idea what several variables are - but the fact that you have a supercharged hemi, have installed larger injectors, and are here asking for a formula is alarming
i recommend you pay someone with experience to dial your tune in for you
preferably me : )
I would be careful as well. As mentioned, easy to kill spark plugs
Do you have experience tuning?
Share your thoughts on how you would do here, so we could discuss
Send me an email for remote tune

Multiplying the startup base table by the inverse of the change in injector flow will get you a good starting point (assuming the rest of the injector data has been entered correctly).
Eg if your original injectors were 600cc and you just upgraded to 1200cc, then multiply the startup base table by 600/1200 = 0.5
judging by his other threads, he is working on a 5.7 based vehicle daniel
his table might look like this:
5.7 startup inj pw.PNG
i do not know for sure tho cuz he is unresponsive
but he should not multiply that table ^^^ by .5
How about helping instead of keep playing?
In case you have the knowledge, share it. Otherwise, find something else to do.
the knowledge i shared was that if yer table looks like that do not multiply it by half
if you do not like what i share, you could always add me to the ignore list, ya know?
you lack power - it is pointless to tell others what to share...
I was just providing a simple example IF the stock injectors were 600cc/min or half the flow of the FIC1200's (assuming they are rated at 1200cc/min @ 58psi). Thus, the correction factor should be 0.5 for this particular example to half the IPW's in the table and provide the same starting fuel mass.
Change the 600cc in the example to whatever the stock injectors are actually flowing and recalculate the correction factor. That will give a very close starting point anyway.
yep
