will i be ok to run 440 injectors with a 6k ecu?

 

no wants 380s, it will drive but be rich on boost and cold start.. lambda sensor if functioning correct will sort it on cruise and idle.

cheers mate

 

if its rich on boost wont that help in the cooling of the pistons or will i just be waisting petrol.the reason im asking i have tdo5 turbo, full decat ported headers and a sti spec c intercooler

 

can you use 440 injectors with the 7k ecu?

 

it will lose power, foul the plugs and bore wash depending on how rich.

pointless exercise fitting bigger injectors unless remapped for them

Simon

 

i was just wondering which injectors the 7k is a map for?

 

I'm chucking some 440's at my car some time soon, *read when I pull my finger out and get them cleaned and flow checked*

Been advised by Andy that mine will run richer in the mid-range and offer some protection at the top end as opposed to the 380's being maxed out (100% IDC) >5200 rpm.

Mapped for them, is the best option, but at present for me it's not viable.

 

all four plug ecus are 380s

thanks jgm

 

just out of interest what would exactly happen if you ran sti phase1 440's on a 7k ecu?

 

i thought the ecu on earlier cars would learn the mods to a certain degree

 

it won't learn the mods on any year.. except to go "oh my god det!!" and pull some timing and hopefully save the engine.. but no it won't realise the injectors are 60cc larger.. the newage ecu is very good and uses a wideband rather than just narrow band and will do a good job on cruise and idle but still be rich as hell on boost with bigger injectors... the narrow band the older ecu has to monitor fueling will trim some fuel off boost but won't learn on boost etc

thaks for your advice jgm
