When upgrading to a set of 680 injectors from stock injectors, how drivable are the EVOs with out a tune / ECU flash? Can the ECU adjust itself enough to run down the highway at 65 mph? I need to know this because I need to drive on the upgraded 680cc injectors (untuned) so I can have the car tuned by AL (Dynoflash). Any past experience or knowledge on the subject will be greatly appreciated.

Thank you

BTW: I’ve searched evolutionm.net for days for a similar question and could not find one or any information.

 

If they scale the ECU for the injectors, you shouldn't have a problem. Caveat emptor.

 

Thread revival time

I would like to know the same question but with 750s...

Can they be drived around town untuned for awhile??

 

Nothing huh guys?

 

I tossed 880cc's in for a small amount of time until we were able to tune (about an hour lol). The idle was lean at around 17:1 and idled rough, but did not stall and was driveable.

I can't say for sure yours will be ok, but that was my experience..

 

i drove around on 880's for a year on stock ecu no problems on my end.

 

Was that untuned though?
