Thread: JWT ecu question

so i have a 91 b13 avenir t25 setup. stock boost z32 maf 370 inj. walbro 255. and its recirculated bov. now my previous motor was a jdm DE+t. i sent out my ecu to jwt for a program of 370cc at 4 bar. z32 maf. AND 9.5.1 compression.
the avenir is 8.5.1 but im running this ecu on hear anyway. would this cause the motor to run very ritch, break up around 5k+ rpm. wideband reads 10.0 and flashes. Also my water temp gauge stays cold and stays there..not even flinch. The fans wont come on unless the coolant temp sensor is un plugged(changed cts to a new one) im confused...can anyone shine some light on this for me please?? thanks!!

i can only feather the throttle to do this. if i floor it, it will break up and sputter from too much fuel. I lowered the fuel pressure to 50 psi..same thing. 48 psi..same thing. i even took out the 370 injectors and put the 259cc injectors. it ran a little better like in the video but still it will break up and sputter if its WOT. I changed the FPR and same issue. WHAT THE HECK!!!!

Check your engine grounds... Mine was breaking up like that because my sensors weren't reading And same w the coolant gauge...I had to groud it to the chasis and boom fixed over somethin I totally overlooked

you re grounded them and it made the coolant gauge work? can ya give me a little more info on wat and how u did.thanks!!

boost leak

^ I could see a boost leak doing that under load, but there is no real load here, unless its one hell of a boot leak.

Do you have an AFPR on the car?

what would leak from a boot leak? sock or toe?

^hahaha typing is owning me today..... BOOST leak.
