Car: 1993 Honda Civic Dx from Canada
Motor: D16z6 P29 Build 12:1 Compression Tuned on crome
Problem: From a second gear pull reving to 7300 Rpms then shifting into third it will be fine pull for a little then at 6200 it will pop up the a CEL code 20 and disable v-tec. We have replaced the fusebox twice, altinator twice and swapped batterys... The ELD is disabled in crome and we have tried mutiple burns of the chip.. If anybody has any advice or solution to the problem please help thanks

 

Bump Nobody knows?

 

bump need some help

uve changed load devices. .but have the checked the wiring??

 

it couldn't be wiring because it only throws the code 20 at high rpms in third at 6400*

 

voltage drop test would work. .i mean technically y would it be the battery at that hi of an rpm cuz it.s basically a voltage stabilizer at that point. .i mean a ground could be loose. .nething. .jus weird it doesnt do it when u rev thru second but does it at a lower rpm n 3rd.

 

how do i perform a voltage drop test? and all the grounds seem fine but ill tripple check and resurface em

 

run ur positve lead on ur voltmeter to the batt+ n ur negative lead to the load device. .u will then get a reading. .then test afta the load device to make sure the device is taking all available power.

 

oh you mean under the fuse box... Ive done those tests and they all came back within spec... is there some way i can perform this test while driving? to see if something happens

 

no no it.s diff as n load devices (ie. ur alternator). .n i spaces this was happening at higher speeds n rpms. .i think it.s due to the vibration. .u need to shake some **** n ur bay n see if u can find sompthin loose. .fuuuck i hate tryin to help ova a forum. .lol. .i wish u lived down the street. .lol.

 

i understand what your saying and ill check to see if there is nething noticable could it maybe be a loose wire pin in a clip or something going to the alt?

 

could this be a bad bin on the chip and maybe it just needs to be made into a new file with the same map? I was told it could be the file please let me know

 

did anybody help this man? i have the same freaking problem.
disables vtec and eld code comes up.
