Dragonball Posted June 20, 2003 Share Posted June 20, 2003 Check out TRL FCD - which most of us have ( think) http://www.trlperformance.com/main.html Check out above on search function for details Highly recommended Cheers paul Quote Link to comment Share on other sites More sharing options...
Guest Martin F Posted June 20, 2003 Share Posted June 20, 2003 I have a HKS FCD fitted. I know it's not recommended, but seems to do the job OK. Quote Link to comment Share on other sites More sharing options...
Rav Posted June 21, 2003 Share Posted June 21, 2003 I also have a HKS FCD fitted, which seems to work fine. Quote Link to comment Share on other sites More sharing options...
daveyboy Posted June 21, 2003 Author Share Posted June 21, 2003 thanks for that. its sorted i will go and get one on monday and try and fit it in the evening. ta:D Quote Link to comment Share on other sites More sharing options...
dandan Posted June 22, 2003 Share Posted June 22, 2003 martin, how come you fitted the hks fcd if it's meant to be less than ideal and the greddy is supposedly the best? Quote Link to comment Share on other sites More sharing options...

Guest Martin F Posted June 22, 2003 Share Posted June 22, 2003 It was already fitted when i bought the car and don't seem to have had any problems with it. Quote Link to comment Share on other sites More sharing options...
Rav Posted June 22, 2003 Share Posted June 22, 2003 Can i just clarify what kind of problems the HKS FCD can cause? I had one fitted with an APEXI AVCR Boost Controller. Seems to run fine, but from the comments in this thread, I am a little concerned. Quote Link to comment Share on other sites More sharing options...
dandan Posted June 22, 2003 Share Posted June 22, 2003 what makes the trl better than the greddy and the hks? any significant difference in cost and/or ease of installation and/or performance and reliability between the three ? Quote Link to comment Share on other sites More sharing options...
THOR Racing Posted June 24, 2003 Share Posted June 24, 2003 It would not be fair of me to say my units are better than anyone elses, all I will do is explain what mine does. Even if you don't consider the unit to function any better then it certainly is cheaper. The TRL VFCC is a Voltage Fuel Cut Controller. (Voltage as there are Frequency based systems as well) The unit has a user adjustable Fuel Cut threshold setting, which on most Supras just remains left at the default position. This REMOVES the fuel cut. But the device also has an Overboost threshold dial which will allow the user to reintroduce the fuel cut at higher boost level. This can be adjusted so that it never triggers and hence the VFCC can be made to REMOVE fuel cut altogether OR RAISE it. Your choice. The device is generic and used for many many car types, like all the Toyotas, Subaru's etc. I'm putting a "How to set the VFCC" section in the "settings" section of the BBS so you can read the process of configuring it. Installation wiring is all on my site http://www.trlperformance.com/vfcc.html The device is 35mm*35mm*10mm so is tiny and has a flip top lid so no screws to undo. Any more info please just ask.

adi Posted June 24, 2003 Share Posted June 24, 2003 so presumably with yours pete the raised boost cuit level can only be set at the maximum readable boost governed by the map sensor? Ie my map sensor maxes out at 1bar so presumably the vfcc in that case wont be able to raise the boost cut limit above this (as the stock boost cut is also at 1bar).

THOR Racing Posted June 24, 2003 Share Posted June 24, 2003 Adi, Correct! 100% The only way around this would be to fit a bigger MAP sensor. Say a three bar one so you can measure 2bar boost and scale the output for the ECU. The VFCC could then be set up to cut at a higher boost. So with a bit of adjustment you could use it, but ONLY with a bigger MAP sensor and a simple scaling OP-Amp. Regards Pete Quote Link to comment Share on other sites More sharing options...
adi Posted June 24, 2003 Share Posted June 24, 2003 the map sensor will come later this year (if i keep the car) but at the moment i occasionally hit boost cut at 1bar... would your unit would be able to clamp the signal for me at say just a tiny fraction under 1bar? (something like 4.95 volts or whatever). Would it be stable enough not to creep up over 4.95 ? (i've no doubt it would be, but i have to ask ) Ive been meaing to order one for ages but i keep finding other things to spend on it.. gotta do it soon though.
