Another vtec issue tried everything need help asap and yes ive searched lol

I have a 96 prelude with a obd1 swapped 97 type s h22a. no vtec
things tried
1.new oil sensor switch on oil filter housing,
2.installed oil guage and reads 50-70
3.has balanced shaft delete
4.motor is crate 50,000 miles
5.pulled apart has oil orphus under middle cam cap
6.cleaned vtec pressure switch and screen
7.hardwired a4 to solenoid and d6 to ground

8.oil pint to half quart over full. has aluminum oil pan
no dents.

9.new temp sending unit but car is running 180 but guage is not moving past one mark. aftermarket guage reads 180

10.hooked up an apexi controller and rpm reads half what the tach reads apexi is withered to read that thru the icm.

11.I pulled the 10mm bolt from the front part of the top right of the head and put oil guage in there at idle it has a small anout of oil that runs out but doesn't read pressure. I get to 6000 rpm and manually enguage vtec and the guage moves from nothing to 70 psi in a few seconds so pressure under vtec but should there be just running normal not in vtec?

12. three computers two modded with cel. knock and 02 delete and p13 stock and no change. modded ecu will hit 8000 and hit rev stock cuts out at 6500.

even with cel delete on modded ecu's the cel comes on? should it.

need help bad fast car is a turd without lol.

motor h22a type s , ported intake side of head, header, lightweight flywheel, bs delete, iab delete, cai, m2s4 with quaife. to add as soon as vtec is fixed, stage 2 cams and valvetrain and 440 injectors

From an outward view in....

Don't need a chipped Ecu if you have a piggyback unit. Also i would say you tinkered too much with the engine and deactivated the VTEC solenoid. Oil pressure not withstanding, delete too many provramming from the stock ecu's vtec will not come on as a safety measure.

What was your diagnosis method?

Pretty much got flamed for driving like a jackass and was told to slow down. And I'll be damned, slowing down fixed it.

{installed saw the rpm issue and removed it immediately don't wanna mess car up so I have a chipped ecu and stock just wanna get vtec first before I tune..

Also i would say you tinkered too much with the engine and deactivated the VTEC solenoid.
{ deactivate solenoid ???}

Oil pressure not withstanding,
{ not withstanding ? it is high on the guage?}

delete too many provramming from the stock ecu's vtec will not come on as a safety measure.
also reset and tried a stock ecu and nothing

What was your diagnosis method?
trial and error checking one thing at a time using desired methods I have saw on the internet
sorry I am new to fwd just doing what I can but may be hurting myself in the process by doing so

Man... Sorry to hear all that. If the stock ecu won't engage the vtec, gotta take out the apex-i piggyback and check at bone stock. Honda motors are technical marvels if you follow the FSM. Following the internet for full builds are sooooo risky

Glad you found the solution. Pics of your prelude please.

Was going to refer you to 98VTEC for a tuning solution if you didnt find one. that guy is awsome.
