Steve Posted March 10, 2006 Share Posted March 10, 2006 I think ideally it should be around 11.4 or 11.7 IIRC Quote Link to comment Share on other sites More sharing options...
Pig Posted March 10, 2006 Author Share Posted March 10, 2006 rich????? u sure! Quote Link to comment Share on other sites More sharing options...
Pig Posted March 10, 2006 Author Share Posted March 10, 2006 I know it should be around that. Just wondering it its safe. havent seem below 10.0 Quote Link to comment Share on other sites More sharing options...
Steve Posted March 10, 2006 Share Posted March 10, 2006 Yeah 10 is rich! Quote Link to comment Share on other sites More sharing options...
Pig Posted March 10, 2006 Author Share Posted March 10, 2006 Score. And to think i was worried. So what is not enough fuel??? Quote Link to comment Share on other sites More sharing options...
Pixelfill Posted March 10, 2006 Share Posted March 10, 2006 Yup definitely rich. If you look at page 9 of your manual there's a table, the first line is 10 AFR and is the lowest reading the AEM will give you. says Rich in the table, the concern I'd be having is that that is as low as the gauge reads, so who's to say it's not lower, and therefore VERY RICH. I'd get this checked ASAP if I was you. the gauge reads from 10 to 18.50 AFR (Air to Fuel ratio) therefore 10 AFR is more fuel than 18.5 AFR i.e. richer 10 Rich 18.5 Lean Mike Quote Link to comment Share on other sites More sharing options...
Homer Posted March 10, 2006 Share Posted March 10, 2006 Thats too much fuel. It'll need to be leaned off a little. What rpm and boost are you seeing this? Quote Link to comment Share on other sites More sharing options...
Pig Posted March 10, 2006 Author Share Posted March 10, 2006 Boost is onle 0.8 bar! What problems may i be causing running so rich? Emanage going on soon, but cant be on straight away\! Quote Link to comment Share on other sites More sharing options...
Pixelfill Posted March 10, 2006 Share Posted March 10, 2006 could a dodgy 02 sensor cause the engine to overfuel (I have no idea but might be an option ) Mike Quote Link to comment Share on other sites More sharing options...
CJ Posted March 10, 2006 Share Posted March 10, 2006 What EMS and injector size are you surrently using? Quote Link to comment Share on other sites More sharing options...
Pixelfill Posted March 10, 2006 Share Posted March 10, 2006 Bigger injectors running at 100% duty cycle would do it. if you've got bigger injectors with no controller that would cause over fuelling (of course I don't know if you do have bigger injectors) Mike edit: doh CJ got there first.

Homer Posted March 10, 2006 Share Posted March 10, 2006 Boost is onle 0.8 bar! What problems may i be causing running so rich? Emanage going on soon, but cant be on straight away\! Knackered plugs, and long term, bore wash. Quote Link to comment Share on other sites More sharing options...
Pig Posted March 10, 2006 Author Share Posted March 10, 2006 Stock ECU lol. Waiting to get the emanage ultimate on. Running a UK spec with 550cc. Couldnt get the emanage ultimate on cause of fucking UK and MAF! Quote Link to comment Share on other sites More sharing options...

Pig Posted March 10, 2006 Author Share Posted March 10, 2006 help...please, still no answers and i dont want till kill my car! Quote Link to comment Share on other sites More sharing options...
Homer Posted March 10, 2006 Share Posted March 10, 2006 Jon, until you get the ecu installed and mapped just make sure you keep it above 10.5 on the afr gauge. If it starts to go off-scale then take your foot off the pedal. That should be enough to help stop carbon fouling. As for bore wash, thats caused by long term overfueling, i.e. new bottom end time Quote Link to comment Share on other sites More sharing options...
Pig Posted March 10, 2006 Author Share Posted March 10, 2006 New bottom end. hmmm, i dont really fancy that lol. will just take it easy then! thanks homer! so as soon as i hit 10 then lift off? Quote Link to comment Share on other sites More sharing options...
CJ Posted March 10, 2006 Share Posted March 10, 2006 Personally, I would not be running the car with an OEM ECU and a single turbo set up. I would wait until the emanage is installed and mapped. Quote Link to comment Share on other sites More sharing options...
letmeshowyou Posted March 10, 2006 Share Posted March 10, 2006 i agree with CJ. I know you've waited a long time to get it back but rather than thinking 'as soon as I hit 10 lift off' it might be better thinking 'do I even want to get to 10 in the first place?' given that it could be even richer than this! Edit: Not to mention how much you must be spending on petrol atm! Quote Link to comment Share on other sites More sharing options...
