Any one ever experience this?
 

shortly after boosting i started noticing symptoms of a maybe a failing alternator. under high rpm or load the lights (both interior and exterior) would brighten and then if i pushed in the clutch and let the rpms' fall the lights would dim back down. under acceleration if i left enough time inbetween shifts the lights would brighten, dim during the shift(when rpms fell) and then brighten again under rpm/load.

current setup is obd2a->1 harness with a chipped p28 on a basemap. however, when i swapped back to my p2p ecu and a vafc to pass state inspection the symptoms completely dissapeared. :S

makes me wonder if maybe i have an electrical short somewhere with the harness and p28.


any help would be appreciated, its rather annoying at night

only solution is to keep it redlined. 8)

your lights ar not part of the wire harness they are wired directly from a relay, fuse to your switch.. maby something wrong with alternator get a new one.

ELD disabled in your basemap?

Re: Any one ever experience this?
 

the basemap was made by a local tuner so im not sure whats in it. what does ELD stand for btw?

Re: Any one ever experience this?
 

well as i mentioned before when i took out the conversion harness and p28 and put my p2p and vafc in the lights were normal. they did not fluctuate

Re: Any one ever experience this?
 

read the basemap with my willem and opened it in uberdata. it does apear to have ELD checked. im assuming checking it disables ELD.

i did some research and it does sound like the ELD was not disabled but from the chip read it appears that it is disabled.

more help?

Re: Any one ever experience this?
 

Well that is an obvious conflict.

Whatever was read by the burner is what was on the chip. So if it says disabled, then it is disabled.

Re: Any one ever experience this?
 

cray- can you clear this up. i think the checkbox in uberdata might actually be to enable ELD, not disable it. there is a box to check for VTEC which is also selected, im hoping that means enable vtec.

here's a print screen, you tell me:

Re: Any one ever experience this?
 

I'm not familier with uber but it looks like eld is enabled to me.

Re: Any one ever experience this?
 

thats what im thinking. i'll reburn the map with ELD UN-checked and take it for a drive tonight.

i'll let you guys know

Re: Any one ever experience this?
 

Heres a link to an eld definition in the pgmfi wiki.

Re: Any one ever experience this?
 

hrrm well i unchecked ELD,saved as a new map, and burnt to a new chip. took it for a spin but no difference :3

i downloaded a crome bin for a near identical setup from xenocron's repository and tested that out in the car just around the block. eld was disabled in that bin and the lights seemed steady.

im still convinced its the ELD feature, maybe im just doing something wrong in uber. i WILL let you know if i stumble across anything but please....

BUMP for some more suggestions

Re: Any one ever experience this?
 

drove around on fook's map but with ELD disabled. lights were rock steady.

im confident its just the ELD setting. if anything changes i'll post but for now, consider it fixed by disabling ELD.

thanks guys ;)

Re: Any one ever experience this?
 

maybe you should swap out the ELD. Im not sure where it is on OBD2 cars but on my EG its built in to the underhood fuse box.

Re: Any one ever experience this?
 

I thought that I read somewheres on pgmfi that crome treats the ELD differently then uberdata (something to do with the way each is programed) , and sometimes the ELD on uber doesnt work as good as crome...sounds stupid but it sticks out in my head

Re: Any one ever experience this?
 

as i mentioned, the problem went away when i changed fuel management to pass inspection. this pinpointed it to the management i was using.



yah, i have weird issues with uber, i like the crome interface MUCCH more.

thanks for the input guys.

Re: Any one ever experience this?
 

ut oh!!! its back.

after driving on a crome map with eld disabled for a week its back. it happened for the first time last night. i daily drive this to and from school (30 mins) everyday and i have not seen any light changes AT ALL until last night. drove it tonight however and had no issues.

i thought for sure the eld had taken care of it. :-X

Re: Any one ever experience this?
 

how is the tempurature where your at. is it hapening when its cold hot . maby condinsation on a positive wire grounding you out. idk

good luck

Re: Any one ever experience this?
 

im in ny so it has been getting much colder. it was rainy the night it just happened.
but as i said before, i rode around on my first basemap (that a local tuner made me) and it happened very frequently over the course of a whole year.i'd say it happened 80% of the time.

i'll look around at my wiring

Re: Any one ever experience this?
 

Look for corrosion, or white toothpaste like stuff around the wires to and from the alternator/battery. You would be surprised at how little corrosion is needed to throw readings off, and if you pull voltages at the terminals you would never know.

Had this same problem long time ago (w/o the chipped ecu), and replaced a battery/alternator, before I replaced the 10$ wire, the wire fixed the problem.

Re: Any one ever experience this?
 

thanks Jay. i'll be sure to give the wires a good inspection and clean up all my grounds.

i'll update this thread sometime towards the end of the week when i finish off my last final
