Looking for a Glanza running EMU or better, and a TD04 or bigger turbo kit :) Cash waiting :) cheers

I thought that since im trimming fuel out with the controller, if it fails it would go rich? But it would hit fuel cut first since the MAP voltage is no longer being reduced. At 0.65bar boost, and standard fpr+injectors, the car is running 11 afr, when i up the boost to 0.8bar it runs 10.4...

just to add some confusion :D Ive found that the stock FPR and injectors can easily run a td04 at 1bar. All you need is a fuel controller, such as an SAFC or SFC Hyper R, to trim the map voltage under fuel cut, at 4,5,6,7,8k rpm points. Ive been running this for a couple days at 11.4 afr WOT...

could be running really rich, i found that 44psi on the rrFPR was perfect for 1bar on td04 at setting 8 on HKS fcd (so many acronyms)

So i put the standard FPR back on, now its doing the opposite! Its idling and cruising rich, 11.4 And at WOT its normal. Ive noticed that removing the vac pipe from the FPR when its idling, has no effect.

yea, unplugged makes no difference really, checked timing and its fine, total mystery this...

i tried changing it a while ago but had no affect, ive also replaced the water temp sensor, and the air intake temp sensor. I checked the wiring to make sure the ecu was getting a reading from the O2 and it was.

i tried bypassing the fcd but it had no effect, must be the fpr or fuel pump, hopefully its the fpr as thats an easier job lol

ok cool, ill try that, i have an hks fcd, and ive just set it to 12 as i was told thats basically off, so ill take it out of the loop completely

the wideband is brand new, i doubt its faulty, because i can feel what it says is happening, if u know what i mean ill try putting the standard fpr on, if it doesnt change ill get a new pump cheers for the help :)

could i test for this by setting up a camera in the engine bay to watch the fuel pressure gauge? and if its dropping its probably the pump? i should have mentioned this before, but sometimes when driving on the motorway at a constant speed, the car will go full lean, then if i lift off or put...

forgot to say, thanks for the quick replies guys, its really doing my head in lol

walbro 255, if it was faulty wouldnt it be worse when on full boost?

yea it feels really down on power, just doesnt want to pull away, then it lurches forward when it spools up, no missfires or backfiring so dont think its ignition

yea ive put it to stock fuel pressure, 2.4bar/34psi its the standard ecu so there must be something wrong surely?
