i have a built h22a, tuned to 7 for break in but limiter at 8, im having trouble with power loss, i will get up to about 180km/h shift into fourth and my engine light will come on and the car will fall on its face like a fuel cut off, it doesnt do this all the time only the odd time, im just wondering what it could be, a safety on crome because its only tuned to 7 and i shift around 7 and half, or a throttle positioning sensor? once i turn the car off the light goes away and i have full power again. any ideas?

 

The issue you are having is not a "safety".

Does the check engine light come on & stay on ?

 

yes, until i turn the car off and turn it back on

 

have you pulled the CEL?

My bet is something with the VTEC solenoid or oil pressure. (this is an ECU setting not an issue with your engine)

 

Check your malfunction indication code while the car is on with the engine running.
Instructions on how to do this are on http://www.phearable.net/tech

 

pulled the check engine light?

and im about to go check the MIL codes now, does the engine need to be running, or can i just turn the key ahead for power?

 

Check the codes while the vehicle is running

 

code 22, VTEC Oil Pressure Switch

 

Bypass the vtec pressure switch. Diagram on http://www.phearable.net/tech

 

ok, my vtec always kicks in, it doesnt kick in and out or anything, just to let you know

 

Does your motor have a vtec pressure switch ?
You need to resolve all malfunction indication lights to have a proper running vehicle.

 

no, once i bypass will it get rid of MIL code, and if i did test again i wouldnt get code 22?
i think when tuning it was disabled but another other guy tuned and enabled it.

 

Yes, it can be disabled in Crome and must've been reenabled if the problem only happened post tune.

 

yeah, im trying to think back and im almost sure thats what happened, but im gonna do an oil pressure check, to be safe, then just bypass instead of driving 5 hours to get disabled on crome.

 

is bypassing that easy? just tap a4 and d6 together and your done, no unplugging of anything? no ungrounding any wires? no nothing?

 

anyone? as i would like to try this out asap!

 

....

 

well actually dont use crome to disable it for some reason it dont work just do the a4 to d6 is ur best bet for some reason when u use crom it get stuck on the vtec map

 

tried bypassing today, now throwing codes 21,22 any ideas?
