5235231 injector offset

Anyone have the offsets for red/blue 5235231 80 pph injectors?
I swapped them in as a replacement for the pink/purple 17104288 46 pph ones after a stroker build.

The link below has .bin file AFTK which should have the 5235231 Injector Offsets. The link below also has the TunerPro $42 .xdf definition for the AFTK .bin file.

Thanks so much Dave!!, I believe that is just what I needed. I figured the information was on here some where I just could not find it. :rockon:

OK so I ran $42-1227747-V5.9.3 to see the bin, I didn't see injector offset, but I did find injector correction multiplier. do I just use that table somehow to modify mine?
I'm running - Advanced $31 TP5 v250, a BMHM bin file on a 7427.

The injector parameters $42 vs. $31 is not a direct crossover. Maybe the early 93 $31 7.4 liter injector parameters will get you close enough to tune, just use the 5235231 injector flow in the $31 .bin file.

17084304 - Black / Blue - 74pph - 7.4L / 454 - 91-93

5235231 - Red / Blue - 80pph - 7.4L / 454 - 88-90

I thought the $31 mask was only used in 95's?
I found a 7.4 bin for an $0E mask but it had the same offsets as my $31, from what I can tell the earlier 7.4 were either a $42 $4f $99 or a $85 all of which do not look to crossover an offset to a $31.
I did find a "93 stage 1, 7.4" (probably one of the Harris chips) but it showed bad data in $31, $0D and $0E masks.
I cant find any bin for an early 93 $31 7.4.
but I'm pretty new to all this so I may just not know where to look?

Thank you so much for your help.

I never did change mine because of this exact issue. I don't have a clue as to how to correlate the tables from $42 to usec values.

Well that's a little discouraging!! LOL.
I can drop ten psi of fuel pressure with the swap, but tuning has been interesting. BLM numbers never really calms down.
