1200cc injectors for e85 and stock 8 ECU...injectors to big for stock ecu??
OK... so I have looked into EVERYTHING about e-85 that I can find, and it is time to make the switch!! My only question is.........
CAN I GET AWAY WITH RUNNING 1200cc INJECTORS WITH THE STOCK EVO 8 ECU??
I know 1000cc injectors will work just fine, but ams prices are $400.00 for 1000cc and $400.00 for 1200cc... So i figure why not get the 1200cc, but I want to know if they can tune them on the stock ecu?
My mode list is below.. I have cams and adjustable cam gears so I figure they should be able to do it. I talked to the shop and they said that it probly would work, but he has never done 1200cc for e-85. He said he has done 1000cc lots and that 1000cc tune just like 1200cc. He also said that he has tunned 1200cc for e-85 on the AEM EMS... and that they tune 1600cc on stock dsm ecu which are simular to evo ecu.
So has anyone else done e-85 switch on 1200cc injectors and stock ecu? I did read about one other member using 1150cc and not having a problem.. but that is only one story.... help me out!!
Thanks!!

Link to another EVO running 1,200cc on E85 here.
It should not be an issue to tune the OEM ECU with 1,200 cc injectors. However, unless you plan to upgrade to twin fuel pumps and a much bigger turbo, I would stay with 1,000cc.
Just because you are getting a 'bigger' size injector for the same price is not a good reason to go big. Size your injector to what you need, plus a reasonable margin, and go with the correct size.
Kind of like buying pants, buy the size that fits your waist even though the XXL is the same price.

And as l2r99gst mentioned, larger than 1000cc injectors aren't going to automatically cause a rough idle. With proper tuning, they can be made to idle as well as stock (even with cams and other mods).
Finally, just so everyone is aware, the original post/thread is over a year old.
