ep91steve Posted February 7, 2010 Share Posted February 7, 2010 hi there.. My car is pretty standerd apart from an open cone filter exhaust and dump valve engine wise.. But a just noticed its got hks fcd! Will this damage my engine? Quote Link to post Share on other sites
Glanza_cl Posted February 7, 2010 Share Posted February 7, 2010 depends if it's actually set up... do you have a boost gauge? what boost are you running?if you are running like 0.85 or 0.9 then potentially yes you could damage your engine, check your boost if to high lower it.with out a rrfpr to increase the fuel pressure you might be running leaner then usual... but thats all dependant on if it's actually doing anything lol Quote Link to post Share on other sites

Jae-Glanza Posted February 7, 2010 Share Posted February 7, 2010 If your only hitting 6.5/7 you'll be fine, because the FCD isnt actually doing anything.. The FCD is there to stop hitting fuel cut which is like 0.8/0.85. Quote Link to post Share on other sites
ep91steve Posted February 7, 2010 Author Share Posted February 7, 2010 Yes. It can damage your engine in the wrong instances.Have a scan at the unit and see what it is set to. The HKS FCD tricks the ecu into thinking it is not boosting as high as it is actually boosting. This avoids hitting fuelcut but also means the fuelling does not match the engine requirements. This is a bad thing.If the FCD is set to 0 then it's not doing anything.If it is set to another number (usually then you need to get the fuelling checked with a wideband. A local tuner is the most likely port of call for a fuelling check.Hope that helps,Jay If its set at 8 mate can a not just take the fcd off? A will go out soon and check Quote Link to post Share on other sites

The FCD is there to stop hitting fuel cut which is like 0.8/0.85.not necessarily, if the fcd is set to anything it will be going something... it could be leaning off the whole boost curve.i would set it to 0 or take it out... unless you want it, in which case get a rrfpr and get the fueling looked at @Mickey , it will come down soon. unless your busting more ethernet crimes!

Set it at zero the now Quote Link to post Share on other sites

ep91steve Posted February 7, 2010 Author Share Posted February 7, 2010 A HKS FCD leans out the whole rev range so it can run lean even at stock boost levels.You can switch it to zero so as it's not affecting your fuelling or remove it but I feel it may have been fitted for a reason - you may hit fuel cut without it.If it were mine I'd fit a fuel regulator and boost controller then go get it tuned.. But a havent got the money to do that right now bud or a would. So what will a do? Dont want to fuck my engine Quote Link to post Share on other sites
ep91steve Posted February 7, 2010 Author Share Posted February 7, 2010 But a havent got the money to do that right now bud or a would. So what will a do? Dont want to fuck my engine Set it to 0 so will everything be ok no its boostin bout 7 as gauge working now Quote Link to post Share on other sites
ep91steve Posted February 7, 2010 Author Share Posted February 7, 2010 Set it to 0 so will everything be ok no its boostin bout 7 as gauge working now Turnd fcd down to 0 now it hiting fuel cut will a put it back to 8 Quote Link to post Share on other sites
ep91steve Posted February 7, 2010 Author Share Posted February 7, 2010 Turnd fcd down to 0 now it hiting fuel cut will a put it back to 8 Just noticed a have hks acutator and it is hit 8.0 boost does that explain fcd Quote Link to post Share on other sites
