I have a 1995 Camaro Z28 with a torqhead 24x setup (LS1 PCM and coils on a gen II LT1)
I bought trickflow tfs-89036 with the expectation it would come with an injector chart, but I can't find data online and none was provided.
Can anyone tell me where to find the correct data? I contacted their customer support two weeks ago and have not heard back.
I finally got a hold of Trickflow... and they sent me a chart with an Accel part number.
Strongly suspect I overpaid for a trickflow branded Accel part

quite possible, if yours are the same as mine(accel part # 150136 single, or 150836 8 pack).....then i'm researching the same thing, where to find complete injector data ...... i hope someone in the know answers you.Quote:

No. Making it run OK at WOT is pretty easy even without any injector data at all. It's the not-WOT parts where the stock PCM needs all the data. If the IFR table is wrong all that happens is the numbers in the VE/MAF are higher or lower than they'd otherwise be. That can cause problems with things that need accurate torque numbers but doing WOT rips to show off to your youtube subscribers how cool you are will mostly go off without issue.Quote:

If the injectors don't come with the stuff needed to fill in that table (and the Short Pulse Adder table) then they are not meant for use with stock PCMs/ECMs.
