i got a chipped p05 + vtec and im getting a code 20. i searched around pgmfi.org but no leads. someone there said they disabled the o2 heater but that doesnt solve my issue. any tips would be good. i added q30 transistor also, no luck. also is there a way to disable the vtec circutry w/o having to remove all the parts i added? just for troubleshooting purposes.... thanks

 

yeah cut J10... think that will bypass VTEC...

wait..code 20? that the electrical load detector...just disable it in CROME...

 

I've had a couple ECUs that always threw a CEL 20 when you jumpered the diagnostic plug, but they didn't set a CEL on the dash.

 

it is disabled. its confusing the crap out of me. ill try cutting j10 and see if it works ok. then ill know if its something i fucked up when i added the vtec parts.

 

I thought J10 just made it possible to run one switch rather than run two 5150's in series.

 

Amusing to watch you take ECU advice from someone who doesn't know what they are talking about, in a thread I posted my commentary in.

J10 has zero to do with CEL 20, dildoes.

 

either way, it didnt work. ....

i tried a different bin on crome and the cell went away. so i uploaded a different bin and i got a cell. tried this several times and it works with some and not with others. weird ----. same code. ill be hooking it up to the ostrich tomorrow and see what changes it doesnt like with rtp. dam p05.

also, the code may not be eld. i get two long solid lights, then an extremely short flicker. i cant 100% say its a short light, its too short, the light doesnt come on fully. im not sure its a code 21. i know theres nothing with the vtec solenoid, no codes with the stock p28. it may just be a gliche? anyone seen that before?

 

RENE, it's probably code 21. Is it a 1720 board? They flash the single digits really fast unlike the 11F0 boards.

 

your right it is. so then what does that mean? somethings bad with the chipping right? what would cause that to happen in a p05 and not in the p28?

 

Did you set up the resistors in RM11 correctly.

1-2 10K
2-3 51K
3-8 12K

Also make sure the transistor in Q26 is in the correct way, not backwards.


Just recheck everything and then see how it goes.
