running rich, wierd idles

[tylercrx]

i got my ecu chipped with the ebay mugen chip, and as a result, my car idles low, it shakes, and it runs too rich. i really dont know how good the chip is, thats why i came here, hopefully to gain some insight. also, i think my TPS is messed right now because my idle is sometimes at about 200, and jumps up to 500 and back to 200, and sometimes its like 1200, and just stays, its always doing something different. my CEL comes on rarely, but when it does i get the code 7, 4 long, 3 short. i checked the crx ecu codes and it doesnt say anything about the led blinking long or short, could anyone explain this to me? thanks for your help.

because those ebay chips are made of an engine with alot of bolt on and high hp motors, like cams and high comp pistons thats why it runs rich because its expecting to get alot more air. those ebay chips sucks

4 long and 3 short is 43 not 7, one long flash is 10 and one short is one, so its a 43

code 43: Fuel Supply System
defective or malfunctioning fuel supply system

could be the chip

thanks so much for the responses, yeah its the chip, i think i should just get a stock ecu...

just realized, how can my car send that error code if the CRX error codes only go up to twenty? im sure the code is accurate, but what accounts for this? thanks.

CRX error codes dont only go to 20, here is my suggestion

step 1

remove ecu

step 2

open ecu

step 3

remove ebay chip

step 4

incenerate ebay chip whilst dancing around the flames it produces

step 5

thank the gods that the ebay chip was incenerated and begin to do another dance, similar to the pee pee dance

step 6

replace ecu in car and go

step 7

never buy an ebay chip or any eprom chip ever again, if you do you and your family will be cursed with 1000 years of pestilence and plague

that is all
