last year i had my car tuned with AEM EMS, and 440cc injectors, for this year i have a built engine and i am going to run 720 cc injectors... before i goto the tuner i want to run the new engine, or atleast let it idle, and do an oil change, just to make sure everyting is ok... now since the EMS is tuned with the 440's will it do any harm to start it with the 720's?? i dont want to wash the engine or be straining a brand new engine?? anyone have a any comments or suggestions??

That would be like trying to get the stock ecu to run 440s, you might get it to idle but driving is not gonna work. Not 100% sure but believe it is correct.

Just plug in the laptop. Go to you fuel tables and right click. choose 'change injectors/pressure' or something worded like that. then put 440 in the old cc and put 720 in the new cc. press enter and you are done. dont forget to save your new calibration.

The 720 cc injectors are gonna open up slower then the 440's so you idle is gonna be messed up. I think u would be able to start it up for a bit but it isnt gonna run too well.

im not intending on driving it, i just dont want the first time the new engine ever turns over to be on the dyno... i have all the software to adjust my ems but i have never done it before, is it that simple ( just go into the table and switch from 440 to 720? and it will recalibrate??)
