i just got a 96 dx coupe, with a 00 b20 swap i got I/E and aem fuel rail and aem fuel pressure reg.. i am running a stock dx ecu. i want my car to run better. i heard b20s dont get the right around of fuel. when i changed the old plugs, my boy said told me im runnin lean. i know i need a B&M fuel pressure gauge to tune my FPR. how will i know when im not running lean any more? i just got a ls ecu, it lets me rev alot higher, but wheni ilde at a stop light, the motor shutts off WHY??

is it a b20/vtec or just b20? if its not vtec but a vtec head on it (b18c1,b18c5,b16)

 

..

 

bump

 

any one??

 

You need to get the correct ecu before you do anything else. I recommend running a obd1 jumper and pickin up a ls ecu. Though this ecu isnt designed for the b20 it iwll work way better then your dx ecu. You can also get a chip or something for the ls ecu which will help out also.

 

i got the 98 ls ecu installed today. i can rev alot higher, but the car just shuts off sometimes? i want to install my B/M fuel pressure gauge today also, so i will know if im still running lean?

 

The only way you are gonna know if your running lean or rich in detail is with a wideband o2 sensor. you can guess, but its kinda hard to dial in without some sort of fuel computer.

 

DID HE GET A BAD ECU?

 

i bumped my fuel pressure to 42psi and the car doesnt shut off! is that too high?

 

tahts cool. leave it
