t3/67 .82ar GE intake ID 1000's 9:1 87.5mm darton sleeve 3" with cat, vibrant res, magnaflow stock ignition external coil. finally got it together and running, just been tuning it by looking at the estimated change to hit target air/fuel. using plx, 0 offset, it was close. when I hit vtec it's ...

gear ratio change? what transmission do you have?

wide band O2 hooked up?
I would recommend not going above 6krpm in boost with out a tune,

stock map only up to maybe 11psi,

what about starting with a b18c map, change injector size, add 400cc in fuel trim for displacement, save as, and presto h22 base map.
then drive around and data log af's.

thats what I did on h22a4, just cross referenced wiring diagrams and put on a td-61u. was only a couple wires to change.

post your tire size. I'm guessing your h23 transmission is in a civic?
vss value must have something to do with tire size.
maybe the prelude / accord has bigger tire size

won't a fuel cut cause a lean condition?
how about dont hit the rev limiter and shift.

pistons ring lands were the weak point on the stock pistons. stock was good for like 300hp for a while. crank up the boost and let 'er rip. Id say 400hp with ur setup, on premium. need a wide band, dyno tune blah blah blah.......

How about a Hour meter??
for those with new engines.

...

There's actually id2000's available. I'm a total noob and I can get my car running with a rough tune on id1000's.

Your fuel pressure isn't to low. It's just if you need to you can get alot more fuel out of your injectors. I think if you up the fuel pressure you also get better misting or fuel atomization. This stuff should probably be in the general forum part or something. I do plan on post my map in here once...

have you tried upping the cranking fuel trim? I assume that just gives it move fuel while cranking, And for the cold start feature, how long or at what temp is classified as cold start anyhow?

you'll get more power out of a aftermarket fan when wired directly to battery and relay turning it on, and probably like a 20 or 30 amp fuse.

you should add a plx wideband, wire it to the ecu so you can datalog air/fuel ratio.
nice setup. similar to mine, I have the same injectors. What kind of fuel pump do you have? some people are running 100psi base pressures on these injectors. I'm only running 55psi with a walbro 255.
