ok so i just got done swapping my 92 ls with a 94 gsr motor. the motor is basically stock. has a skunk 2 1st. gen intake T.B. spacer, header, intake exhaust. well... it starts up perfect and idles perfect. but when u give it gas or hard accelerate as soon as u get around 3k it completly stops almost like a boost cut or something. my buddy got it to go 2 4k with maybe 10% throttle, then it basically hits a fuel cut or something. i have tired the stock ECU pr4, chipped p28, virgin p28 virgin p72 and s300 with 5 diff. maps uploaded. well i ran vtec and pressure. but obviously it was not going 2 hit vtec because of knock sensor. but with s300 i turned off knock and still the same thing. car was low on gas so i went and put 1/2 tank and still the same thing. physical timing is dead on. ignition timing is dead on. i have tried 3 diff map sensors still the same thing. it also did it with the stock intake and no t.b. spacer. the kid drove the car 2 my house with the ls in it with rod knock, but it still ran fine b-4 i swapped.

ALSO...on s300 it keeps throwing the ELD code
i also looped power stearing. any ideas

 

did u chek to make sure u didnt mix up map sensor and tps plugs i think there the only two that are alike ..got all grounds hooked up ?? did u use ls wiring harness ???

 

ya. the motor is in a DA so the map sensor is mounted on the wall. all grounds are hooked up and fine. yes it is an LS harness

 

so did u ever thing that maybe a non vtec wiring harness wont work on a vtec motor with out mod .. and alos is the gsr motor odb2 or 1 i cant remeber wat year u said it was

 

sorry odb1 ... and my bad for the horrible spellin its late

 

also number one ? is there a cel

 

no cel's yes i have pinned the ecu for vtec. only half assed ECU code i am getting is ELD, but then again all that does is stabalize your volts.

 

anyone else?
