well im releived cuz i finally got the CELs cleared. hooked hondata up and car runs good. untuned, but good. but its been giving me a similar problem that i had before.

well the setup is LS/VTEC in LS body with GSR harness. ITR head. well i beleive there might be a vacuum leak, but i cant find a hose that could cause it. the problem is when i accelerate above a certain RPM the car just kinda shuts off. not shut off, but the gas goes limp.

i have a 190 fuelpump, 370cc injectors and fuel pressure is about 47psi (hose off)

can anyone give me some possibilities of what this prob can be.. perhaps which hoses to check over. the only hose i have off is the hose that goes into the AEM intake. and i also dont have the "factory catch can" mounted, so the hoses to that are also loose.

thanx for the help

 

What kind of Hondata system are you using?

 

hondata s200 stage 3 with p28 ECU.

 

u fool!! the golden rules for hybrid swwap is to use the stock harness off your own car not the other, i tried to put a full same year gsr swap with gsr harness onto a ls integ and boy everything was fine but it felt liek **** and pussing the gas all the way to make it rev and it struggle.. u need to take that gsr harness out and put back the ls harness ontot he gsr and use the iab,v tec, k.s connectors and runt hem straight to the gsr ecu.. this will be a perfect brand new swap..i thought oh... ill just out a gsr motor with gsr hanress onto a ls intgera, it just an added v tec with k.s and iab, but i was wrong. it will go without codes btu it will run mega shitty. just put the ls harness on and runt he added wires need for the gsr ecu

 

Have you taken out any fuel form those injectors yet? 370's + 190 pump sounds kinda big for just a lsvtec.

 

Well, if you decide to let the GSR engine harness go I need one...

Let me know.

Thx,

Mark

 

yah i figured the fuel is overload. i might step down to soe 310 injectors. or even in the 200's.

 

On my crvt I am using oem 240's + 255ho pump + 50psi and mine is runnin hella rich.
