This is not needed to be done, And or if you need to go higher it isnt a problem either...

The Ecm is using lots of tables for its base fuel injector size. If you still want to have resolution and fine tuning control via the injector flow rate table there is a simple fix...

Look at table, B1213. This table will allow you to run ANY size injector big or small, and all you to modify the injector values in B4001 to allow more resolution.

Say you are running a 80lb injector, Obviously, the Fuel injector table will have to be maxxed out if you just change B4001. However, if you left the injector table stock and just modified the table B1213 BY THE PERCENTAGE of difference of your new injectors, What happened to your tune???

Everything is now back to normal..
Thanks Jess....I've messed with a bunch of other methods when swapping to larger injectors.....

While there's a few different ways to do it...(and lord knows I've tried all of them) I think this is a really neet approach and it seems to be working just fine.

My LS2 injector IFR table is stock and I've got the Siemens 60s in there and it's running and tuning GREAT! And as an added bonus, my VE table values are finally sane!

Thanks for another great idea.....
