Gpro Posted May 30, 2013 Share Posted May 30, 2013 i have had my ecu for a few years now i decided today to download windows xp and plug the laptop in to it. I had it on live datalog and realised that it doesn't show my RPM when i accelerate it shows which box is active right now and it only goes down the left side with pressure but doesn't pick up RPM. I aint an expert but surely the map aint really active now is it? with no RPM signal? Quote Link to comment Share on other sites More sharing options...
Fly Posted May 30, 2013 Share Posted May 30, 2013 On data log is the rpm n on the left or are you talking about the map windows where voltage is against pressure? Quote Link to comment Share on other sites More sharing options...
Gpro Posted May 30, 2013 Author Share Posted May 30, 2013 I have attached pictures. When in live datalog it shows you what box your currently in (Red) it only goes down the first column also in full throttle it shows 0.2% injector duty cycle i aint a mapper but surely something doesn't look right. I can't see how this would work without a RPM signal Quote Link to comment Share on other sites More sharing options...
Ian C Posted May 30, 2013 Share Posted May 30, 2013 The duty cycle is a percentage of available time, which is based on revs. It'll read artificially low as it thinks it's basically got infinite time to inject fuel at 0rpm. You need to check the wiring at the ECU, if it's not getting an RPM signal it'll only ever use the left hand column of the map, which is badness.

Gpro Posted May 30, 2013 Author Share Posted May 30, 2013 And theirs me thinking the car is running on emanage ultimate! for the last 2 years when only 1 colum works! i am curious how come it aint running lean when i am on boost? (Low boost) 0.7 bar 10.5 AFR Quote Link to comment Share on other sites More sharing options...
Ian C Posted May 30, 2013 Share Posted May 30, 2013 (edited) Well, it might have only just stopped seeing the revs. Your injector map is doing bugger all anyway from what I can see of it. Got a screenshot of that and the airflow adjustment map I can look at? Edit - and the ignition timing map, why not.

Ian C Posted May 30, 2013 Share Posted May 30, 2013 Heh I sense I've been near that EMU somehow in the past, those RPM load sites are custom and exactly what I set them to Quote Link to comment Share on other sites More sharing options...
Gpro Posted May 30, 2013 Author Share Posted May 30, 2013 does this map look good? i notice theirs a lot of 0s in a lot of boxes is this normal for lower rpm Quote Link to comment Share on other sites More sharing options...
Gpro Posted May 30, 2013 Author Share Posted May 30, 2013 (edited) here all the maps. Also it was last mapped by Ryan G 2 bar tuning Can someone answer me this question is killling me! Why are we removing fuel as the revs go up and boost increases. shouldn't we be adding fuel?

Guest Seoul4korea Posted May 31, 2013 Share Posted May 31, 2013 What RPM signal wire are you using? Quote Link to comment Share on other sites More sharing options...
Gpro Posted May 31, 2013 Author Share Posted May 31, 2013 What you mean what wire? I will strip it apart today and try source the problem. Going to tap in to the stock ecu rpm wire Quote Link to comment Share on other sites More sharing options...
Gpro Posted May 31, 2013 Author Share Posted May 31, 2013 i fixed the rpm and guess what it was running very lean! on boost so i added some fuel back in their. Can someone look at my ignition map and see if its ok? i am running a single turbo by the way. the map was originally mapped the tt bpu Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted May 31, 2013 Share Posted May 31, 2013 Just had a quick look at your ing map, cant see any point in retarding the timing below 2,000 RPM, if its mapped for the stock twins then it really shouldn't need any retarding until higher than stock boost levels unless it showing signs of det which it also shouldn't.

Gpro Posted June 1, 2013 Author Share Posted June 1, 2013 This is the emanage ultimate log of ignition timing Ignition timing: Yellow Boost: Blue Throttle position: green RPM: Red Also the timing retard under 2,000 rpm won't make a difference as it will never hit them boxes (0.4+ bar) Quote Link to comment Share on other sites More sharing options...
