hey guys what wood happen if i put magna 210cc injectors in my fto with stock ecu :O will i kill stuff? anyone done it?

lols why would u want to do that

stock size is 166cc...

210cc is 26.51% bigger... and without something to control the over sized injector the ecu will just think its a 166cc and have a 50% duty cycle like its 166cc... ull run rich and kill the cat and the environment!

not sure about 50% duty but it doesnt really matter as it the duty will only decrease from stock due to the bigger injectors as u have no supporting mods - no CAI and new wheels doesnt count.

The O2 sensor will correct the A/F ratio and since they are not that much bigger I assume it has enough resolution to do so - thats what the o2 sensor is for.

IMO is wont do anything useful, but it will be fine but wont add any performance. Not having fitted magna injectors before, the O rings and wiring might need ot be changed - not sure if their direct replacements.

^^ Quite right. You gotta modify fuel rails to make 'em fit. If you're running non-turbo now, the stockies should be fine. Out of the factory the fuel systems only runs at 60% capacity on full throttle.

On the other hand if for some reason you wanted bigger injectors, the most cost effective solution is the 6A13 injectors. 390cc is huge, but they do fit straight into the FTO rails with no mods required.

I got the 390cc injectors in mine... Had to get a decent ECU (microtec LT10s) to control them properly. Only paid $150 or so for the set 2nd hand.

Really? Thats interesting... got 'any pics? I was looking for bigger injectors for my blower setup but didnt want to go all the way to 390cc....

the O2 will only be able to control them when the ecu is at close loop mode which is pretty much at idle and cruising, but when accelerating it won't be in close loop, some thing like that anyway, correct me if I'm wrong.

They only operate at when they are at temp. Hence your car usually runs rich on startup....u can smell it. Until they are at temp they are in Open Loop.

The only other open loop condition I'm aware of is Full Throttle the rest is closed loop as far as I'm aware.
