Dragonball Posted November 15, 2004 Share Posted November 15, 2004 Thanks for that Wez - interesting to see that your injectors are only maxing at 75% at 6500 Just some great information that one can glean from this system by the looks of it!

Wez Posted November 15, 2004 Author Share Posted November 15, 2004 Yeah i know but thats under a 1 bar boost with increased fuel pressure on 440cc. Quote Link to comment Share on other sites More sharing options...
Wez Posted November 15, 2004 Author Share Posted November 15, 2004 Another thing to note on these is that the turbo has no boost control at the moment, the wastegate is feed direct from the manifold. With boost control setup (on my to do list) I will be able to bring in more boost earlier as I can prevent the wastegate opening until I want it too.

MONKEYmark Posted November 15, 2004 Share Posted November 15, 2004 seems like you getting to grips with it. what made you go for the aem with stock turbos and 440cc injectors. is it more a long term thing? Quote Link to comment Share on other sites More sharing options...
Wez Posted November 15, 2004 Author Share Posted November 15, 2004 Was always my goal to go single and I like the amount of control it offers. These plots are from my single which still needs some mapping. I have ready to install a 3.5bar MAP, 650cc Injectors and a new GM IAT sensor. Just need some light warm weather or a nice big garage to get it all done. Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted November 15, 2004 Share Posted November 15, 2004 I've got a nice big workshop. If you want to borrow a corner for a day, you're more than welcome. Quote Link to comment Share on other sites More sharing options...
Ian C Posted November 15, 2004 Share Posted November 15, 2004 You need to set up a narrower set of y axis' on those graphs to get better resolution It's hard to see what the O2 sensor is getting up to, and the RPM chart goes up to 12000rpm+ :O Looks good though, can you get at the results in table/csv format? -Ian Quote Link to comment Share on other sites More sharing options...
TLicense Posted November 15, 2004 Share Posted November 15, 2004 You can expand each channel so that the max/mins Y axis are whatever the max/min Y values are. There's also a statistics tool which enables you to see what the max min Y values are, for each logged value, and it also tell you at what value of x they occur. VERY handy piece of kit.

At 1.2 bar and 7000 RPM IIRC my duty with the 440's was around 85%. That's also with an > 1:1 FSE fuel regulator. A definite testiment not to run more than 1 bar with stock regulator and 440cc injectors. They just aren't man enough. Quote Link to comment Share on other sites More sharing options...

Wez Posted November 15, 2004 Author Share Posted November 15, 2004 Originally posted by Ian C Looks good though, can you get at the results in table/csv format? -Ian Here is an example of some output in text format, the amount of data is huge plus you can manually change the sample rate, i currently have mine on approx 50 samples a second as i am only interested in approx 20mins of data at any one time.

TLicense Posted November 15, 2004 Share Posted November 15, 2004 Wez, How do you set-up the internal logging? Basically I want it to log continuously, and loop around once it's done. I've set the conditions that I want so that it should log all the time (eg speed>0, load>-20, throttle>0) but I can't actually get it to start logging. If I go to the logging menu, and click start it basically want's to start external logging. I've obviously missed something. Cheers mate, Tony Quote Link to comment Share on other sites More sharing options...
Wez Posted November 15, 2004 Author Share Posted November 15, 2004 you need to set the switched input to always on or a switch you have wired up, plus always log needs to be on if i remember correctly, see attached image. EDIT: just to add that to download you have to have ignition on but engine off and select download internal logs from the ECU menu. Quote Link to comment Share on other sites More sharing options...

Fantastic stuff The graphs are all well and good for an overview but load site tuning needs that level of data IMO -Ian Quote Link to comment Share on other sites More sharing options...
Wez Posted November 15, 2004 Author Share Posted November 15, 2004 Its pretty good plus the rate of samples is configurable, it depends how much time you want to record. See attached image for both ends of the scale, i think 250 times a second should be enough. Quote Link to comment Share on other sites More sharing options...
Dragonball Posted November 15, 2004 Share Posted November 15, 2004 Anyone interested - Wez in Coming round to my place next Wednesday for a demonstration of the AEM set-up etc Couple of beers and a pizza await (kentucky for Dude!) if anyone wants to pitch up!
