4agte fuel consumption bad after Link tune.

[suberimakuri]

i had 550's on megasquirt sweet.

slideways: your car has been tuned right?....... so if you mess with the injectors or anything else, your tune is no longer going to be as 'optimal' as designed by the tuner.
You could go put 185cc injectors in if you want, but your AFR will suffer for it.

In any case, sounds like economy with bad tune on ITB's.... or you doing every other km >0psi.

since you have another set of gze injectors available do a swap, see if the problem follows,

speed tech have a very good name so would have thought it'd be spot on, have you spoken to andre about the fuel consumption problem? what did he say?

ok a couple more questions for ya.
what fuel pressure are you running?
what fuel pump? standard? aftermarket?
what fuel reg, standard? rising rate?


edyn ive had good results with 440cc injectors, i think bazda using 510's?

I haven't spoken to Andre about the fuel consumption yet. I have been back though, because it misfired on 13psi...just needed colder plugs. Also I've only just emptied the first tank today.

On the last 1/4 of the tank I only drove on low boost (7psi) and 80% cruising.

It has now just touch 250km!? This seems very weird because thats EXACTLY what I used to get with the standard AFM ECU!?

Fuel system is completely standard (AE92 GTZ).

Could this all be due to the injectors?

Thanks alot for everyones help so far 8
