Does anyone know what bhp a standard fuel pump for an AUM engine can handle?
-
There is no definite number seen as these cars are all quite inks now and many of the fuel pumps arnt as good as they used to be!
So with any decent power you should be looking at upgrading the pump for safety.
There was a aum at r tech last week where he stopped tuning at 200bhp because the fuel pump gave up!
A new aum unit will give about 260-290 bhp

did you not just have a new 1 fitted at r-tech :smiley:

I did have one fitted there because my old one couldn't stand up to the job for stage 2. It came from TPS and is the standard one for the AUM. The reason I ask is because three times while driving and putting my foot down, suddenly there is no power at all, although the car is still on and running, it is as if the accelerator has just stopped working. While this happens the EPC light came. As soon as I re-start the engine, the car is fine again. This does also throw a code up showing a problem with torque!
I just thought that this may of been the new fuel pump that caused the problem.

cant see the pump being the problem i might be wrong though what codes does it throw up :smiley:

Yeah, that is what Nick at R-Tech said too. He told me to clean the TB and do a TBA and adjust the actuator to two turns of pre-load.
The code it showed was 17743/P1335 - Engine Torque Monitor 2: Control Limit Exceeded
Cheers

nick will have a better idea than me :grin: ross tech info
Malfunction Indicator Light (MIL) ON
Reduced Power
Possible Causes
Intake hose(s) or intake system leaks (Unmetered Air) after MAF
Intake Air Temperature sensor faulty
Mass Air Flow Sensor (G70) faulty
Engine Coolant Temperature sensor faulty
Restricted Air or Fuel Filters
Possible Solutions
Check intake hose(s) or intake system for leaks (Unmetered Air) after MAF
Check Intake Air Temperature sensor
Check Mass Air Flow Sensor (G70)
Check Engine Coolant Temperature sensor
Check Air and Fuel Filters
Special Notes
Check O2 Sensor(s) Adaptation Values Before Clearing Faults: Fuel Trim Information

I've also been gettin that code but I put it down to me puttin a slightly bigger turbo on and not yet having the map adjusted! But I'm not 100% sure
Update and let us know if you sort it please :smiley:

I have been looking it up on the net and there are various suggestions of the cause, from the maf to the actual map! So I don't know what to think, but I do know when driving in the fast lane of the motorway doing 70ish :wink: it is a bit of a scary moment when the throttle response totally goes, especially at night time!
-
Update for those who are interested.
I did a TBA as Nick at R-Tech suggested and all seems well. I have had no more EPC lights come on or that torque code show either. All I have had now and then is the traction control light flicker sometimes when I put my right foot down.

Your problem will absolutely be down to having a bigger turbo than it's mapped for.
It's basically the new turbo is producing different figures on the maf that isn't correlating to the expected boost pressure/throttle position. Its a conflict in the 2 load readings and closes the throttle as it thinks there is an issue with the dbw pedal system.

Yeah I figured as much that's why I haven't posted about it :laugh:
