downimpact Posted March 27, 2012 Share Posted March 27, 2012 I found this link while searching for my problem with the car running lean since going BPU, I suspected the HKS FCD and this seems to back up this up. http://www.mkiv.com/techarticles/bcc/why_bcc/Why_the_GReddy_BCC.htm I can't find greddy BCC's available as it seems discontinued according to GReddy, is there another product that does the same think without getting a piggyback ECU. n.b. I've taken the car to a rolling road who confirmed it is running lean, I've replaced the fuel pump with a walbro when going bpu. AFR reading is around 12.2 with WOT.

Slicknick Posted March 28, 2012 Share Posted March 28, 2012 I have one of these fitted, mine was supplied by chris wilson but its the same thing ; http://www.ebay.co.uk/itm/TURBO-BOOST-CUT-FUEL-CUT-DEFENDER-ELIMINATOR-MAP-SENSOR-hks-controller-fcd-/220969030244?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3372c7d264 Its a doddle to wire in and works exactly the same as the bcc by clamping the voltage from the map sensor just before fuel cut meaning the engine is unaffected 99% of the time and will only lean out a tiny bit on WOT. I have this fitted to mine and the afr's were 10.5 at WOT so certainty not lean. Hope that helps. Link to comment Share on other sites More sharing options...
mattdavies Posted March 28, 2012 Share Posted March 28, 2012 (edited) I recently asked a similar question http://www.mkivsupra.net/vbb/showthread.php?264044-Greddy-Vs-HKS-FCDs I am intrigued by the ebay FCD, although a little hesitant. do you know anyone else that has used this item ?

Slicknick Posted March 28, 2012 Share Posted March 28, 2012 I gather Chris Wilson has fitted them to many supra's, I checked mine with a multi-meter and it completely un-affects the voltage from the Map sensor until the point where you set it to clamp and it holds the voltage solid. Seems to work just fine. The only real difference i think is that the Greddy is pre-set and this one you have to set yourself but its really quite simple.

mattdavies Posted March 28, 2012 Share Posted March 28, 2012 How do you connect it in, i seem to remember on the greddy there are 4 wires ( ground, +ve, in and Out ) Link to comment Share on other sites More sharing options...
Slicknick Posted March 28, 2012 Share Posted March 28, 2012 You have the usual Ground and +ve but instead of having an In & out wire there is just one which piggybacks/splices onto the sensor wire and clamps it that way, saves having to cut the wire into the ecu.

mattdavies Posted March 28, 2012 Share Posted March 28, 2012 i see, i am apprehensive but i think i will go for it Link to comment Share on other sites More sharing options...
Slicknick Posted March 28, 2012 Share Posted March 28, 2012 By all means talk to Chris Wilson or the chap that makes them and see what they say, AFAIK the Greddy uses simple diodes as I'm sure this does, its probably only the packaging that's different! You don't have to take my word for it but just offering some advice Link to comment Share on other sites More sharing options...
mattdavies Posted March 28, 2012 Share Posted March 28, 2012 I prob will talk to chris simply for piece of mind, I am not doubting you but am apprehensive about 25pound on ebay when I can get a new BCC for 80. Link to comment Share on other sites More sharing options...
