Okay i got my new ecu intoday and injectors. I took my car out for a ride and my rpms went up to 7 but my boost gauge stopped at 0. I didn't hear the bov when i shfited. How can i get up to 7,000rpms but get no boost? Thanks. Jim

 

did it have boost before the ECU and injectior instal.

 

nope

 

i just got the ecu in today, this is my first time trying to drive it. Thanks

 

it runs good other then a 4k idle......:X but i am not getting boost still....

 

keep changin parts till you get boost!...

Nah man seriously sounds like you have a boost leak somewere in your charge piping......wait...we've been down this road before..."are charge pipes installed?"

Check for leaks in piping/couplers
with the engine idling, look into the turbo inlet(were filter goes) give the throttle a quick snap and see if the turbo spins freely.

Check to be sure the wastgate is not stuck open.
Sorry i wish i could help more but i don't know the cars history and mods and such.

Sure is a boost leak somewhere.. Look around at your charge pipes to find it..

 

post up your setup.
check for rips in your couplers.
make sure your WG lines are routed correctly.

 

How can i make sure the waste gate vaccum is routed properly, where do you guys connect it? Also exenocron burned me a basemap and sent me a ecu with a zif in it. It is running extremely rich and fouled out my plugs. I hope he can send me the basemap he used so i can adjust it. At first it ran good at a 2k idle but no boost, after a while it started running rough and the idle got worse and worse. Now my idle is at 5k and the car sputters back and forth. Im guessing it fouled out the plugs cuse its running so rich.

 

here is my setup.

1990 Acura Integra LS 1.8
-Custom Built full race turbo manifold
-GREDDY RS TYPE BLOW OFF VALVE
-2" Intercooler Pipe Tubing Kit
-Front mount intercooler
-TiAL 38mm TURBO WASTEGATE, Polished
-T3/T4 Turbo .50 A/R STAGE III GARRETT WHEEL
-dsm mitsubishi honda 450cc fuel injectors blue top
-Half Radiator
-T3 T4 TURBO OIL LINE RETURN KIT OIL DRAIN -10AN FITTING
-T3 T4 TURBO OIL LINE FEED KIT TURBO OIL INLET FEED KIT
-Greddy turbo timer
-High flow catylitic converter

 

its a brand new turbo so i doubt its bad? Can they even be bad if there is no wear or play on the shaft? Thanks, Jim

 

Now that i see the setup i'm wondering if if your running as rich as you say you are....with a fairly moderate sized turbo if that would cause the problem but i'm sure you would still get somthing. if the turbo spins freely and has no shaft play then it's fine.

 

i got it creating boost, i had a intercooler pipeing blow out. My idle is 6k rpms tho! it was doing that before i boosted, wtf can cause that!

 

You you have a vac. line that isnt connected somewhere, check all your vac lines.
