injector questions

[moparich]

just finished my stroker build for my 96 grand Cherokee

will the ford 24lb injectors work with my 96 truck? if so could i get some detail for injector purchase

They'll probably work fine but that'll depend on the specs of your stroker build.

thanks,

i found some 24lb inj specific for the 96-98 cherokee's.

i built a poorman stroker mild cam, mild headwork. im using my stock ecu so i now am looking into the map adjusters.

[moparich]

ok so i was doing some looking and my stock injectors flow 23.7lbs/hr.with my poor man stroker should i be stepping up to 27lb/hr inj?and with that do i have to use a map adjuster?

27 will be a bit large. Find an injector that flows 24 on the rail. What is the pressure on a 96 ZJ?

OIC

these inj Bosch 0280155715 will flow 24lbs/hr @ 43psi. my stock fuel system should be 41-43psi

do you think i will still need to do the adj map mod

Your stock injectors flow 23.3lb/hr so they're already pretty close. You might only need a MAP adjuster to fine tune the fuelling.

Don't count out PCM re-mapping. I have a known good tune for a mild 4.6 on mild 24's. I very much get trying to do things on a budget but retuning the stock ECU through reprogramming is well worth it.
