Crash Bandicoot Posted February 11, 2018 Share Posted February 11, 2018 Hi all! Looking for some help/advice. I’ll start with my setup: J spec 1997 switchover facelift 6speed Manual from factory. So has the non vvti engine but facelift clocks etc. I’ve just completed a hks t04z single turbo conversion: Hks t04z turbo Hks manifold Hks 3.5” downpipe Hks gt2 wastegate Blitz dual solenoid boost controller Sard 800cc drop in injectors Bosch 044 fuel pump New fuel filter Fuel pulsation damper bypass Apexi 3 bar map sensor Apexi power F.C. standalone ecu Defi racer egt gauge (plugged in on turbo exhaust housing) Defi racer boost gauge Defi oil pressure gauge Aem uego wideband I removed the hks fcd while doing the conversion. It has a turbo timer I haven’t played with. It has an alarm system (that has never worked) never played with. I have ordered a fpr to monitor the fuel pressure (it sounds pretty loud at the stock fuel rail, almost as if there’s air disturbance inside). The oem lambda sensor that comes out from under the driver footwell has never been fitted since I have owned the car. It has both 1st and 2nd decats since I’ve owned it. It ran perfectly before the single conversion and I carried out a compression test before the conversion which came back with solid results. I fully charged the battery today and did a data init. On the apexi power F.C. hand controller, so it could run the “self learn” process and set itself a base map Here’s what happened: Oil pressure sits at 6bar when cold, and slowly drops to nearer 2 as it warms up. I did a data initiate before anything and then started it with no changes to the boost controller settings or injector settings as I read online to let it self learn first without changing anything. It ran for about 11 minutes to warm up and worked it way through these revs, started at about 1100 for about 30 seconds-1 minute, then went up to 1500rpm for about 3 minutes and gradually dropped itself down to 700rpm over the remaining 6-7 mins and when the hand controller was showing between 680-720rpm it decided to die again. Now I don’t know if that is a failed self learn because it cut out or what so I went to start it again and it fires then cuts out. So I started it with a little throttle and it stays running until I let the throttle off and it cuts out again. I’ve ordered a fpr but it’s not turning up until the 19th. So I won’t know if it’s fuel pressure related until then. I’m just surprised that it runs good until it’s warm and then decides to play up. Any ideas?

Crash Bandicoot Posted February 11, 2018 Author Share Posted February 11, 2018 Forgot to mention, I have removed the fuel pump ecu and bridged the two larger blue wires so that the larger fuel pump runs off the ignition Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted February 11, 2018 Share Posted February 11, 2018 To start with check the ECU coolant temps sensor resistance, hot start running will be bad if this has failed, secondly, PFC will only learn idle control, and it also will not be able to lean warm idle without the std lambda sensor.

Crash Bandicoot Posted February 11, 2018 Author Share Posted February 11, 2018 I managed to get it sorted (I think) when data init. Was last done, I forgot to chance the pim volt setting to the apexi map sensor, changed that and carried out the self learn process again, now all is tickiddy boo Quote Link to comment Share on other sites More sharing options...
