loss of power in second gear

[adamrogers3091]

No power FC, just the back box.

I didn\'t think you needed power FC until you started to add various parts. At the moment I just have the back box and 1 large single air filter.

in your earlier post you said it didnt have a cat, if this is the case you could be hitting fuel cut due to boost spikes but im certain someone else will be able to confirm

sorry Kris, yeah running decat with standard pipe and aftermarket back box (unsure which one.)

Can anyone confirm Kris\'s boost spike possibility?

Kris is correct, shouldn\'t run without the cat if you haven\'t got a Power FC. Stick a cat back on and it should be ok (should be dirt cheap to buy as well).

Yup also your risking running lean and killing it before you get going tbh mate, my money is on fuel cut through running on stock ecu without the cat now with that added information.
 
Stick the cat back in and try again or you can get a restrictor plate for where the cat joins the dp.
 
Better still get a pfc and mapping and keep your decat as it releases loads a powRRR lol.

[FD3S Efini]

i agree with Neil JDMR, best options are to either put the cat back on to save the engine or get a power fc and get it mapped which will boost the power by a decent amount.
 
At the moment the last thing you wanna do is hammer the .... off the car because it will det and ruin the engine, hope this helps mate

Adam there is the standard cat,there is nothing wrong with the clutch, the plugs are less than a year old, As for the oil leak as i said on the phone the only thing i have done that side is replace the oil gauge sender for a known good one, i was not prepared for the amount of oil that came out because you can only replace this by feel! which is very difficult! very messy! thinking about it that could be still leaking, i would have thought any oil i spilt would be gone by now! the reason i think that is because i don\'t think these senders should need any plumbers sealing tape because it needs the thread to ground for the gauge to work, (tapered thread) as for the turbo problem, i only had that happen once a couple of years ago, but when i switched the ign off then on again it never happened again, lack of use of the turbo\'s may be a factor, while the engine has been run regularly, not so with the turbo\'s, but they were fine when we tested the car, be intersting to see if that happens again, but try and note the boost gauge and revs,

thanks everyone. right little update.. after driving the car tonight the power cut has happened in second gear once again. I payed close attention to the RPM and it happens around 5,500 not 4-4.5rpm.
 
It\'s on and off though which is strange, the second turbo spooled just fine at full pelt but then I lost power when changing to 3rd gear and spooling and on second turbo. othertimes in all gears it\'s been just fine.
 
Conclusion = def a problem with the second turbo and me very confused.
 
Based on this new info do you all stick by the by getting the power FC? bear in mind Bob has corrected me above saying I do in fact have a standard cat.... what to do??

[FD3S Efini]

A power FC is good for the future and also a standard car can get quite good gains aswell but if it has a cat then its not really needed.
 
the real question is are you planning on modifying/upgrading the car?

just a random punt but are you low of fuel?
i know for fc\'s if you run less than 1/4 tank and acc hard or turn hard then there is fuel starvation to the pump. is this a known problem for fd\'s?

[adamrogers3091]

FD3S Efini - I am getting dual filters but at present thats all, this will change in the future though... so any ideas on the problem based on the fact I do have the standard cat?
 
L18M - I did have a start of the night then filled up and it still happened as above. thats why I filled up and when I left the garage and hit the gas it didn\'t happen so I though great!!..... until it happened

[FD3S Efini]

im not to sure on the problem now mate because i thought it was decatted hopefully someone will be able to come and help you out, sorry i cant be of more help
 
Kris

[adamrogers3091]

Idea\'s anyone?

[ro284]

I payed close attention to the RPM and it happens around 5,500 not 4-4.5rpm.

Well it\'s not been revved to anywhere near that in the last 6 years Adam! So i\'m out of ideas,:xconfused

As far as the low fuel i have nailed mine hard with the gauge on near empty and never felt any issues. A pfc mapped by a rotary tuner will sort out all your probs mate and at the time get a decat pipe from one of the many breakers/tuners on here.
 
It still sounds to me like fuel cut, are you using v power fuel ?
