update
Update: I've got at least five tanks of E85 through the my Evo with these injectors, and the injectors are still perfect. Idle to WOT is all excellent. Still starts perfect under all conditions.

I haven't tried the BlueMax 1250s, so I couldn't say which is better. Bryan has commented a few times that the BlueMax's seem to work pretty well. All the propaganda on the internet says that the advantages of the new generation of high impedance (Bosch) injectors over low impedance (BlueMax) injectors is better pulsewidth consistency at low pulsewidths (idle, cruise), a more linear fuel delivery as a function of pulse width, and a finer mist of fuel with a wider spray pattern. The FIC1100s behave pretty much like my FIC1050s with the exception of a more stable idle, and slightly better gas mileage. One issue that is not specific to injector type is warm starts. Some warm start well while others warm start poorly. There is still no definitive answer on why some are better than others. My FIC1100s are warm starting fine on E85. Have yet to try gasoline.
Shunting the resistor pack is pretty easy. If you do a search in the ECUFlash forum, you should be able to find some pics and a description. There is also some info in the AEM forum where there is an ID1000 thread.

Traditionally, low z injectors are better at idle and cruise. The bluemax injectors came out to fulfill these conditions better than the older low z injectors. The high z bosch injectors is supposed to be better than the bluemax, which is supposed to be best at idle/cruise?
Thanks!
Thanks!
Anyone Else have Scaling/Latency Values they'd like to share?
Mine seam a bit out of whack for some reason:
FIC 1,100's
93 octane pump
Scaling: 943
Latency:
3.312
2.112
1.656
.984
.528
.336
.216
I either have to go WAY high with scaling or lower the latencies a lot otherwise my trims go way lean and sometimes max. Anyone have any recommendations? I'm on SD BTW.

Here is what I've got.
With this set-up my trims are withing +/- 2%, startup is great, idle is great, etc. etc.
If I reduce the VE vs RPM tables then raise latency i have a pretty bad stumble right off idle that effects driveability a lot.
What do you recommend mrfred?

That's what I figured. Only thing is I'm going to have to play with the Boost range on the VE tables as my Wideband doesn't match the values in the Fuel table. It's close, but not perfect.

OK, this is kinda strage b/c whatever scaling I'm using for these injectors (current one is 1218) I finally always get trim -12,5%. Higher value I put - longer it takes to climb to -12,5% but its always the same. I'm using Detschwerks 300 LPH fuel pump if it does matter.

the dw301 is probably overrunning the factory fpr.
