dr_jekyll Posted May 30, 2009 Share Posted May 30, 2009 ok can someonne please please please tell me how to make my f**&ing emb add more fuel wen on boost, its on a basic na-t runnin 7psi , i have every other aspect of the setup ok after hourse of adjusting and driving. (more luck than judgement) it idles at 14.8, easy driving and motorway cruising at mid 14s but when go on full throttle at 7 psi it will not go below 12.9 and 11.5 is my target i know idealy it would be best to give it to a pro like ryan g but i feel like im so close with the overall map and hes really far away. could some one plese tell me what needs to be adjusted to ad that little bit more fuel that is needed.

Homer Posted May 30, 2009 Share Posted May 30, 2009 Which values are you entering in the A/F map while it's in the target range above 7 psi? Also what injectors and ECu do you have? The EMB can only correct +50% over base values. Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted May 30, 2009 Author Share Posted May 30, 2009 i have standard injectors and the 2jzge ecu. at 100% throttle i have it at 9 on the air flow correction map. i have it at 5v on the greddy pressure sensor aditional injection map and 5v on the sub injecor map. i belive the votage output can only be between 0-5v Quote Link to comment Share on other sites More sharing options...
Homer Posted May 30, 2009 Share Posted May 30, 2009 Can you post your current map on here? It'd help diagnose any issue, though it's highly likely the injector limit is your issue along with the obvious one using an NA ECU. Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted May 31, 2009 Author Share Posted May 31, 2009 ill see if i can uplode my maps tomorrow. i had a previous na-t that was had standard ecu and injectors and that ran low 11s on full boost at 9psi? what other ecu could i use?

Probably easier just to attach the current map or even just screengrabs of them. 7psi boost is 50% more air than the engine would normally see, I'm not sure if you've got 50% headroom in the stock injectors? 370cc I think? Never mind the additional fuel on top of that to increase the AFRs... Still, it would be interesting to see the map -Ian Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted May 31, 2009 Share Posted May 31, 2009 Sounds like the presets for scaling the maps have not been changed. Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted May 31, 2009 Author Share Posted May 31, 2009 (edited) here are my settings , i apologise for the poor quality but my useless windows vista wouldnt allow me to upload them from the unit so i had to take pics of the screen but it can jus be made out , Edited June 1, 2009 by dr_jekyll (see edit history) Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted May 31, 2009 Share Posted May 31, 2009 Don't see the point in scaling the additional injector map by the sensor voltage? why not use pressure, makes things easier, also why are you using the sub injector map? do you have extra injectors?

Sorry mate but that statement tells me that you really need to get somebody who knows what there doing to map it, like Ryan. Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted May 31, 2009 Share Posted May 31, 2009 nightmare im in ibiza from wednesday for 2 weeks , do you venture this way often? Im everywhere But over in wales about once a month at mo.

In gloucester the most at the moment which isn't far from you Ryan will you ba able to map the car with the standard injectors , or should i get 440s and a walbro . i wouldnt want to get you down here oinly to find the current hardware is not capable on this particuar car, but my last one was on standard and that got down to 11s Quote Link to comment Share on other sites More sharing options...
Ian C Posted May 31, 2009 Share Posted May 31, 2009 Dude The load cells are %age duty cycle, NOT a voltage, the voltage is just the Y scale (the left hand column)... You're only adding in 5% more duty cycle at most... No wonder you aren't really affecting the tuning, try putting 40% in there and see if it suddenly bogs down overfuelling... Normally I'm game for people "having a go" but I think you need to at least scour the instructions for the EMB to understand how it works and what it does afore ye blow the car up Or just let Ryan work his magic -Ian Edit - plus erm the sub injector map? Won't do anything unless you have extra injectors wired up... Quote Link to comment Share on other sites More sharing options...

Stock injectors should be fine at only 7psi Stay off boost for the time being though!! Quote Link to comment Share on other sites More sharing options...
