Hey guys i have a check engine light on n maybe u can help me ...... i checked the codes n i have 2 i have a 4 CKP Sensor (Crankshaft Position Sensor) anf its also throwing a 20 Electrical Load Detector i have crx wit ls/vtec i also have a chipped p28 wit a neptune program ..... and idk y but since that ma car wont rev past 3500 rpm's so any thing will help thanks guys ...........

 

its your ecu who did your chip and tune... my friend tried doin a mugen chip in a p28 and wired it wrong by 1 spot and it only ran up to 3800 wat that is is safe mode cuz the car doesnt know what it can do basically and the crank your gana have to wipe your codes and drive and see if it comes up again and if so then you will have to pull and rebuild your block make sure everything is torqued down right and not sittin wrong... how does it run generally

 

well i have tried 3 diff ecu's n all have brought those codes n isnt the 4 CKP Sensor (Crankshaft Position Sensor) in the dizzy ?

 

it runs really good like it doesnt choke or anything i jus cant rev past 3500

 

all the ecu's wont let you rev past 35? hmm try reseting it (taking out the ecu fuse for 10 sec) after you plug in an ecu and try reving it... any check codes?

 

right when i start the car it throws a CEK

 

CEL not CEJ ma bad

 

wats the code number and i'll see what i can find out
