Hey new to honda world, own 95 acura integra b1.8b1 turbo, wiesco pistons light weight clutch, flywheel, 14.5 compression running 10 psi boost.with 440 injectors. What ratio fmu should i use? All with stock ecu and no check engine light except under long boost cycle any advice?

 

^ lol.



i wouldnt dream of running boost on a 14.5:1 motor with only an fmu. you need to do a lot of research it sounds like.

 

New to the honda scene this is what i have . B1.8b stock bore ls crank, weisco 14.5, crower rods, stock ecu fuel pump 3 inch down pipe ,block guard oil cooling system, Big help i might ad, running 7 psi - 10 on 93 octane, stand alone wideban.drive car every day, jus like too eat up the v8 boys, pulls very well 2and third. Live in VA so have emissions. So no check engine light.o by the way ase master mechanic. The only problem i have is the fact that lost ac, but building new engine with good parts but useing a saab turbo and lower compression, got to have my ac

 

you need to get some variation of tuning. no two ways about it...and by the fact that youre in virginia and talking about emissions, id say youre in nova. there are a number of people on here you can get in contact with that can help you bro.



btw, i sacrificed a/c for boost a decade ago.

 

Thanks for the input ended up making my own pipe, from turbo to cat, and another one that will work with cat jus swap it every two years thanks tho.On the tuning side definitely agree im old school tuning using wideban and reading the plugs.jus use it for the v8s teg needs a v8 good for it yummy

 

i still would put some emphasis on getting some sort of fuel management. you say youre running forged pistons, which is better than stock ones without fuel management, but youre risking finding out how long it will run without tuning..

 

Totally agree, the fmu keeps AF ratio 13.9 to 14.6 when at operating temperature, cold start runs rich,and yes on the forged pistons weiscos.I am currently building a real power plant the only problem with that is The WIFE lol.New engine will be supercharged, Easy way too keep ac, plus much cleaner look need to get more pieces to the puzzle, I guess its how deep are your pockets and the knowledge to do yourself!

 

fyi, that AFR with that compression ratio is recipe for disaster.

 

[QUOTE=boostjunkie757;50051536]fyi, that AFR with that compression ratio is recipe for disaster.plugs say otherwise

 

must be keeping it richer than 14:1 then, because anything leaner than that is starting to get risky..

 

You got me thinking about that .Took it to my friends shop checked the exhaust readings on emissions dino.Definitely. had plenty of fuel, med black color while pulling 2ed,3rd. Found faulty wideban o2.ordered new one , but from the numbers Im guessing 8to11 to 1.I let you know what new o2 reads.Thanks for your input any recommendations on decent cheater slicks

 

lol...i dont know much about the o2 readings issue..



mine doesnt have an o2 sensor set-up...the tire question im still working on figuring out as well..

 

Yea the target number under full load should be around 11.1 to 12.5 to 1, means rich but not washing out, but at steady cruse should be around 13 to 13.6 and at idle as close to 14 as possible. You stated you use no o2 , whats your feedback on data.
