Luke.R Posted October 9, 2014 Share Posted October 9, 2014 Hey guys, Had a problem for ages where my EP82 will run lean on boost, even on standard boost I'm seeing 13's.So far I fitted an uprated fuel pumpNew fuel filter RRFPR. Now the only way I can see 11's on boost is by running 4 bar of fuel pressure, which is way too high. So I'm getting kinda stuck now Quote Link to post Share on other sites
Luke.R Posted October 9, 2014 Author Share Posted October 9, 2014 Also I'm now running a Blitz Access Ecu and it's still the same as the standard one. So I'm thinking a mechanical problem rather than electronic. Quote Link to post Share on other sites

Luke.R Posted October 9, 2014 Author Share Posted October 9, 2014 Standard. But at standard boost they should be fine? Quote Link to post Share on other sites
Stu Posted October 9, 2014 Share Posted October 9, 2014 What sort of wide band are you using to check the afr's? Can you datalog a run and post the result? Quote Link to post Share on other sites
Luke.R Posted October 9, 2014 Author Share Posted October 9, 2014 I'm using an Innovate Wide band. I've just re-calibrated it, so will take it for a run and see if the car actually has a problem or if I have been lied to by the wide band lol. Quote Link to post Share on other sites
Stu Posted October 10, 2014 Share Posted October 10, 2014 They're a great unit - just make sure you free air calibrate it ie take the sensor out of the exhaust when you do it.Datalog a run and screen dump the log. Quote Link to post Share on other sites
AdamB Posted October 10, 2014 Share Posted October 10, 2014 Air intake temp sensor possibly. Quote Link to post Share on other sites

I had a similar prob on my bog standed ep91 no error code etc spoke at length and done checks with Dave b and found sensor was faulty.

Luke.R Posted October 10, 2014 Author Share Posted October 10, 2014 Sorted it. Had to re-calibrate the Wide band. Now it's between 11.9 - 10.9. Cheers for the help guys. Quote Link to post Share on other sites
