Chipped P28 throwing code 20 'Electrical Load Detector'
 

I chipped my p28 and put an uberdata burnt chip in it. I put the ecu in my gsr and started it up. It runs for like 3-5seconds and then throws a CEL. checked the code and got 20; Electrical Load Detector. The car runs fine and the code doesn't seem to effect the motor. Has anyone had this problem before? or know what it means? Did I put the chip set in wrong? Am I burning the chips wrong? Are there tests I can do to check? Any help would be great.

Disable it :6

i got that code once before too, replaced my dizzy and redid a few grounds and it was gone... i doubt the dizzy had anything to do with it though

i'd suggest double checking your grounds and going from there

I doubt you have a CEL 20. Recheck the codes, look closely.

The CEL blinks two times and they seem long, not short. The code is either code 2 or code 20. I'm assuming it has to do with my chipped p28 because the CEL goes away when I put the stock p72 back in. If it is code 2(o2 b sensor) can my p28 be picking up something that my p72 doesn't? What is code 20 usually caused from?

who chipped it ???

Re: Chipped P28 throwing code 20 'Electrical Load Detector'
 

Check codes after dark, or in a dark garage. Look closely. Some of the ECUs blink single digits really really really quickly. I doubt you are throwing a CEL 20 with a chipped ECU and not a stocker... I could be wrong, but you need to verify that before we go any further.

I chipped it myself so that might be the problem, but this isn't my first one. I've never had problems before. I'll go back and check the code at night and see if I missed a blink or two. Plus, my friend has a code reader that reads obd1 codes so I'll probably go over there tomorrow and check it out for sure.

I doubt you have a chipping problem if the chipped code comes online and spits out CELs. You probably have an issue with your code, and are flashing a VTEC code for various reasons and just missing the short blinks.

make a vid and post here..

Update on CEL. So I went to my friend's house and hooked my GSR to a snap obd1/2 reader. The reader was unable to read the chipped p28 and kept repeating 'no communication'. Plugged in a stock p72(gsr) and the reader worked fine and displayed 'no codes'. Then, I plugged in a non-chipped stock p28 and reader displayed code 20 ELD(electrical load detector). The reader said it was a 3 pin connector located in the underhood relay/fuse box, but I could not locate it. So I've proven that its not my chipped p28 that is causing the CEL because the stock p28 acts the same. My question now is: what makes the p28 not compatable with the GSR? And for all of you that think a p28 works on a gsr fine, keep in mind that you can have this code and NOT have a CEL. When I put the stock p28 in and started the car it ran without a CEL, but the snap-on reader was able to detect it. My guess is that an OBD1 civic either runs a different electrical load or has a sensor that the GSR doesn't have. Does anyone know what exactly this code is? Is there a specific sensor on a GSR or civic for this?

ELD has nothing to do with the motor and everything to do with the car.

ELD is in the car, behind the fuse box like you mentioned.

If it is causing you issues, just disable it in the chipped ECU.

lik ei said.. disable it :6

your car does not have a Electrical Load Detector your old ecu did not use one and the p28 does.
