Would i be able to use a piggyback ECU that is turned off someone

I'd just shell out for a haltech or megasquirt

On the off chance this is not a troll post:


No, that will not fucking work at all. How are you planning the adjust fuel pressure on the fly to hit your AFR target? Protip = stoich isn't what you want.

If the piggyback (MAPECU?) is tuned for a similar setup, it should be good enough to get you to a proper dyno/tuning shop to get you dialed in. Just stay out of hard boost on your way there. If you don't know what you're doing, be extra careful.

If it were me, I'd do a pull on the street and watch AFRs to see how close it is. Chances are it'll be close enough even with a tune for another turbo.

Is that an skyline?

Very nice color.

I have a vpro in my z. Almost impossible to find tuners for them in Aus/nz because the tuner has to be hks certified and the interface is all in Japanese. You would be better off just buying a nistune or another cheap piggyback

Yes, but there's always small differences.
If it's tuned conservative and not on the edge it will work fine.

The computer accounts for load and pressure. When that load and pressure happens makes no difference to the computer.

Fuel pressure regulators do that on their own..

If the other car was tuned on the same injectors then what does it matter.
