hi guys need your help over the winter i have done quiet a few mods on my R33 RB25 car like power fc , 550cc, Apexi turbo, external, pump etc on the start the car was running really bad pendling between 0-600rpm i found out it was because of the oil catch tank and after blocking the small hose from the head going back the the plenum this was fixed ( i think) the car was fine for a few minutes at about 750rpm after warming up the rpm dropped to about 450rpm engine running very quiet and smooth after stepping on the gas up to 4000-5000 rpm the engine is reving fine but on the way back to down engine is stalling straight to zero tuck a short drive with it but the engine is always shutting off when i push the clutch pedal otherwise the engine is performing fine... i heared about a AAC valve what needs to be cleaned sitting on the plenum could this be the probleme ? Please let me know im thankfull for any help please ignore my spelling and gramma =) dino

i realy want help ok no problem i will make some pics tommorowof the 2 still damaged engines the Neo engine is abit white over all pistons so probably to lean the R33 engine was normal black like normal all sparks plugs look fine to me braun/black just found strange that all cars have the same problem but the one RB25DET NEo is already rebuilded now here the details of the 2 still damaged engines one R34 GTT Damage happen on higway at 260kmh HKS Intercooler HKS Power intake HKS GT2835 Pro S @ 1,2bar Tomei head gasket DI splitfires Forged Pistons 88mm Forged Rods Forged Stroke NISMO 480cc Oil Catch tank Stock Plenum Stock Exhaust manifold Polished head intake and Tunnels Kakimoto Exhaust (no cat) Apexi Power FC AVCR 3 Blue screen NISMO Coppeer mix probably run to lean on the high way for a long time R33 damage happen on highway too 120km Greddy Intercooler HKS Power intake HKS GT2535 @ 0,8bar Oil Catch tank DI splitfires Stock Injectors Stock Plenum Stock Exhaust manifold Kakimoto Z01 Exhaust (with cat) Mines VX ecu AVCR 3 Blue screen Cusco twin platte here i dont understand why ? maybe its just the age?

yeah on the power fc i would understand also, but the R34s are dyno tuned air fuel ratio etc all perfect but on the close to stock engine R33 with ready tuned ecu`??? dino

hi Guys i have a ECR33 RB25DET series 2 now i plugged the Apexi power fc in to the car and used a commander from a R34Gtt here the problem after i start car, the Engine is not running well (because the PFC is used maybe the settings doesnt match with my car could be) but also the Commander freezes up on Apexi logo, cant go in to the menu dosent react at all is it the wrong commander`? and maybe i could use a datalogit to set it up or is the power fc unit defect? dino
