kieren1234 Posted March 15, 2008 Share Posted March 15, 2008 Hi all, my friend has been mapping his na-t using the Lm-1 to do datalogging and then making the necessary changed on his e-manage blue. Could you taker a look at this log and let me know how it is please...... Many thanks. Quote Link to comment Share on other sites More sharing options...
kieren1234 Posted March 15, 2008 Author Share Posted March 15, 2008 Done more mapping and are at this stage. Any thoughts guys??? Quote Link to comment Share on other sites More sharing options...
JamieP Posted March 15, 2008 Share Posted March 15, 2008 AFR 22.39 in the first and 13.6 in the second? Quote Link to comment Share on other sites More sharing options...
kieren1234 Posted March 15, 2008 Author Share Posted March 15, 2008 Your not looking in the right place :) That is just showing the point at where the mouse was hovered over when taking the screen shot. AFR's and RPM on on the left axis. Quote Link to comment Share on other sites More sharing options...
Homer Posted March 15, 2008 Share Posted March 15, 2008 Unless I'm reading those graphs wrong it looks horribly lean. How much boost is it running and in what gear were those logs from? Quote Link to comment Share on other sites More sharing options...

The logs were done in 3rd gear at WOT. The car is running 0.6 bar of boost. Car is definately running lean. He hasn't finished setting it up yet so has more to do on the e-manage.

Tricky-Ricky Posted March 15, 2008 Share Posted March 15, 2008 Its way to lean on closed loop, by the looks of it, but with it being an N/A ECU i have no idea how they process an positive pressure signal either?? Quote Link to comment Share on other sites More sharing options...
Sean1933 Posted March 15, 2008 Share Posted March 15, 2008 Looks stupidly lean if im reading it right, so lean im suprised it didnt Quote Link to comment Share on other sites More sharing options...
kieren1234 Posted March 15, 2008 Author Share Posted March 15, 2008 Cheers for input guys, i will forward on your responces to him. It is massively lean and was even worse before he started mapping the e-manage. Will update you all and many thanks for the prompt comments.

JustGav Posted March 15, 2008 Share Posted March 15, 2008 The logs were done in 3rd gear at WOT. The car is running 0.6 bar of boost. Knowing the car is running lean and then doing 3rd WOT runs... might as well just put a grenade in the sump and have done. Common sense will go a long way...

Homer Posted March 15, 2008 Share Posted March 15, 2008 It's also very important to have the boost pressure logged against the afr & rpm. It's pretty meaningless to map without knowing the boost. The EMB software can is capable of doing this. Surprised it hasn't gone bang with those afr's. Edit - looks like he's using the LM1 software rather than the EMB datalogging Quote Link to comment Share on other sites More sharing options...
Whitesupraboy2 Posted March 15, 2008 Share Posted March 15, 2008 If he is mapping that he should stop now and pay someone. Quote Link to comment Share on other sites More sharing options...

I will let him know, his internet is down at the monent so i will give him a bell and tell him your comments. Regards. Quote Link to comment Share on other sites More sharing options...

IIRC the 0-5v output from the LM1 needs to be wired to one of the additonal inputs on the EMB (can't recall right now). That'll allow the afr reading to be logging by the EMB software.

I will hopefully be removing mine tomorrow so will be able to tell you the colours/input Quote Link to comment Share on other sites More sharing options...
Homer Posted March 15, 2008 Share Posted March 15, 2008 All the details of the various wideband to EMB setups have been posted here in the past, but it'll take some time to dig out all the details. For example the LM1 has a linear signal were as the AEM I used had a scaling one. To be honest it sounds like your mate doesn't know what he's doing. Anyone who has the slightest idea of fueling will know that if those AFR's are correct the engine will be busy lunching itself. I'm not convinced providing him with the correct logging will allow him to setup a safe map... Quote Link to comment Share on other sites More sharing options...

Hermit Posted March 16, 2008 Share Posted March 16, 2008 Wow that is lean... but I reckon that point's been made enough by now I'm pretty sure that on the Blue you use the airflow2 input to get the wideband signal into it. It looks as though it goes lean as soon as it gets +ve boost gotta be a clue that... Has it got a greddy pressure sensor on it? Or anything?

TLicense Posted March 16, 2008 Share Posted March 16, 2008 The AFR's on the first plot are a little special aren't they? I take it that's him lifting off because it was lean missing? Quote Link to comment Share on other sites More sharing options...

Ian C Posted March 17, 2008 Share Posted March 17, 2008 Has he actually changed to bigger injectors? And judging by the state it's in later in the rev range, a couple of grades colder plug? 19:1 afrs at 4000rpm good lord. Seriously, it might be time to do a leakdown test after all that. -Ian Quote Link to comment Share on other sites More sharing options...
