Upgrading Injectors/Fuel Pump = Upgraded ECU Needed?

[Honda_CRX]

Hey all....Q_Ball said to post in this section, so here gos....

Tuner said setup needs larger injectors and pump, am told H22 injectors and a Walbro pump will do fine, BUT you will need Hondata mainly because of the injectors etc.

Is that correct? Am running Apexi NEO and Factory ECU(37820 P30 G01 775 303984 AXP denshigiken)

Its a B20 i/h/e

Do i have any other options :confused: or do i have to buy a new ECU etc

Thanks all

you need to have your P30 modified so you can run crome or hondata
then the tuner can tune the engine to match all your parts

I thought the Apexi NEO could run with different sized injectors... and therefore the pump should be ok.

IMHO, i/h/e is probably not enough to warranty the NECESSITY for upgraded injectors and fuel pump. You could try to find a tuner which can tune without those upgrades and see how you go.

i believe NEO is just a piggyback with limited points to adj?
Should be able to do the job, just maybe not the best that's all.

I've heard people tuning Neo to even run boost.

Some tuners recommend bigger injectors as necessary when doing any mods as it is easy cash for them. The number of cars I have seen with huge injectors that did not require anything other than factory ones is ridiculous.

yep i believe it's piggy back... but agreed, limited tuning points mean the tune wont be 100%, but with i/h/e, there wont be much lost from a non-100% tune :) i'm guessing only a few kw, and save ur money from the injectors/fuel pump and new ECU.

IMHO, the difference will be marginal with the new injectors/fuel pump/ecu...as in not worth spending $2k for the sake of a few kw.

for what you've got.. an AFPR is sufficient... and tuned with something...

as said by many above injectors/pump are unneccesary for bolt-ons
