Anyone with a class 3 can spray, including me, but you are a flat out idiot if you are admitting to that as a home protection weapon. Repeat after me, limit collateral damage.
Off topic again huh? Im guess you retract going to the safe for situations like this and really ment it for plinking down range- right Ill 1000m you got a Barrett for that too- and yup whatever I grab first the MP or riot Benelli - some sports are more serious tan others

Scaling these numbers down for larger injectors is like lowering a car by removing the tires.

Injector size should be accounted for by the injector scaling parameters. That's why it's there in the first place. Using this method, your fuel table will still represent a realistic a/f target table and closed loop fuel control will still work as intended. Of course, you'll have to know where to find it in the code. Right Al?

Figured I'd jump in since my name keeps on getting brought up...

The reflash will prolly be better and depending how they test either will prolly be fine if done properly

The only problem I have with the reflash is if I want the car back to 100% stock for troubleshooting it that is not a option.

Interesting theory you have there!

I have been quite sucessful at getting bigger injectors to work well with the reflash - I have run 1000's on my car and now I have 780's and it runs just like stock with the reflash so in actual practice my method works very well - in fact my motec wideband shows my closed loop fuel control is right on the money !!!!!

Thats why i like to experiment on my own car before I try it out on a customer.

Have you tried to get some bigger injectors woriking with your reflash machine yet ?

I will keep your sugestion in mind!

Wrong again - we offer FREE reflashes back to stock and then back to your own map which we have saved under your name AT ANY TIME for ANY reason

Just have to finish what you started, since you did not answer my on topic response about resetting ECU. Much like Al, I grow weary of your drivel, so I am done sorting through and replying to you. They don't allow .50s on our 1000m, but it figures that's what you'd have, as that's what most untrained, uninformed personnel think is best. I hope your shooting is better than your grammar, or our range officer will kick you off after one shot.

So are you ever going to answer my questions, or just keep up your bravado about things you wish you had?

It's not just theory all. It's just knowing the code, its functions, and taking advantage of it. That's what they are there for. Trying to backdoor things will lead to other complications. You're approach is wrong on many levels.

What question about resetting was addressed to me? Of course Id try it if I had seen that behavior. Im from Texas we dont get marched into little cubicles to plink our .22s we have all the space in the world and really I guess I should stop wasting my money with the SEAL that works with me. Anyone is welcome to check the things I wish I had- just have em show up @ 0200

If I get a flash and want to do away with it what do I need to do? Also do you think the SAFC can get me through the obd2 test with bigger injectors fuel pump and 264 cams?

Once you have the flash - you can go back to stock at any time - at least with me - either stop by the shop or fed ex me your ecu and I will reload the original factory maps for free!

Our big injector approach has work perfectly so far. Larger injectors represent about 1% of our clinets as the vast majority of our reflash clients are totally stock OR mildly modified. We have not seen any complications on any of the cars we have flashed - big injectors or not, but we are constanly doing update testing and re-dynoing on selected cars to monitor and verify that our settings are constant and repeatable.

So far the repeatability on the Dyno Flashed cars over time and in different tempratures has been as close to perfect as we have seen with any engine management.

There are certainly more than one way to skin a cat and we look forward to seeing how you approach the reflash.

After now having obviously a chance to learn the ins and outs of the reflash method on Evos, which method do you feel is a better option for stock Evos the reflash or the Exede?
