1 - I have a stock 92 JDM H22A block with a USDM 95 H22A1 head that had been shaved to the low extreme of a brand new head, but just above disgard. I had another .015 taken off the head, and bought some cam gears to make up the loss of distance between the crank and cams.
So what is my new compression? or how do i calculate that. I think stock was 10.0 to 1

2 - I have a vafc with an AEM uego wideband and no O2 plugged into my ecu. What is bad about not having an O2 that the ECU can see if I am keeping an eye on the AFR while i'm driving.

3 - What is the best air/fuel ratio for a stock motor with a little upped compression and all bolt-ons other than a header and fuel delivery system. (intake exhaust flywheel pulley camgears)

other info i'm running low 13s with this H in an EG and i'm trying HARD to get 12s this summer with what i've got. I really need to know what AFR is best, and can't afford dyno time to check it myself at 120/hr

 

Target 13:1 air / fuel ratio at wide open throttle on a setup like yours.

Do your self a huge favor.
Sell the vafc, look into crome, uberdata or hondata.

 

that seems to be the general concensus with the whole crowd about my vafc.
now how about that crome/uber/hondata

how does that work with an H

as far as I understand I have to find some other obd1 ecu and chip that.

anyone running a chipped H-series that can give me some advice?

13.0 to 1 is the best then?

 

14.7:1 c/r ratio is best. But that's a thin line to hold. That why you see 13:1 12:1 11:1, better for the long run.

 

D-CeReaL#4,
I believe you're wrong. 14.7:1 is "best" (in books) in terms of efficiency. (think gas mpg, etc).

Just because it is considered an efficient ratio does not mean it will make the most power.

To the original poster. If you are street tuning, think of suggestions like 13:1 as a safe spot for you. But you wont know the best AFR for YOUR CAR, unless you get it tuned on a dyno with a wideband as well. there is no magic number, even if honda-tech says so but once again, many of these magic numbers will keep your engine safe. power is a whole different story.

peace.
