Luke.R Posted October 9, 2014 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
Luke.R Posted October 9, 2014 Author 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
Duduglanza Posted October 9, 2014 Posted October 9, 2014 (edited) Mate I ran 4bar on mine for ages.. no problems at all. Edited October 9, 2014 by Duduglanza Quote
Luke.R Posted October 9, 2014 Author Posted October 9, 2014 Standard. But at standard boost they should be fine? Quote
Stu Posted October 9, 2014 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
Luke.R Posted October 9, 2014 Author 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
Stu Posted October 10, 2014 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
jellybaby Posted October 10, 2014 Posted October 10, 2014 (edited) Air intake temp sensor possibly.X2 it a sensor that I widely overlooked when people have fueling probs. 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. By them from new from toyota but they not cheep but mine been perfect since and even now I have it in my new forged engine Edited October 10, 2014 by jellybaby Quote
Luke.R Posted October 10, 2014 Author 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
