Scruit Posted February 9, 2012 Share Posted February 9, 2012 Woohoo. Anyway, using RomRaider, which counter should be looking at for boost pressure? I saw a couple of "target boost" counters at topped out at 9.5psi (I'm 100% stock) so is that the right counter? Before I try to put a tune on the car I was wondering what counters I shoudl be looking at to get a picture of the overall health of the engine. I'm thinking knock, timing, A/F and boost. Anything else I really need to look at? Will log on the way home and post logs tonight. Link to comment Share on other sites More sharing options...
bmx045 Posted February 9, 2012 Share Posted February 9, 2012 manifold relative pressure corrected. knock sum feedback knock correction fine learning knock correction rpm (engine speed) engine load g/s throttle plate angle wastegate duty put it i 3rd gear, at 2k rpm floor it all the way to redline, post the log file here Link to comment Share on other sites More sharing options...

bmx045 Posted February 9, 2012 Share Posted February 9, 2012 the stock o2 sensor (a/f in RR) is not applicable in wot runs, it pins at 11.14(lowest value for oem sensor) and is not an accurate representation of your actual AFR, though, in actuality, your real afr is probably lower than 11.14 but not entirely certain. That's why you need a wideband o2 sensor to monitor that. Link to comment Share on other sites More sharing options...
Scruit Posted February 10, 2012 Author Share Posted February 10, 2012 I didn't find all of the counters you mentioned, but I selected counters as close as I could find. Hope I got this right.

bmx045 Posted February 10, 2012 Share Posted February 10, 2012 Useless. Romraider has feedback knock correction and fine learning and knock sum. Try again. only log at the point at full throttle 2k-redline. My scroll wheel would appreciate it. Link to comment Share on other sites More sharing options...
Scruit Posted February 10, 2012 Author Share Posted February 10, 2012 Here's the thing... I remember seeing knock sum in the list last night, but it is not in the list now. I had the software open at my desk (was going to save your counters as a profile) looking for the counters you requested but some of them are not there now. I will plug back in to the car and see if they appear again. Link to comment Share on other sites More sharing options...
bmx045 Posted February 10, 2012 Share Posted February 10, 2012 Once you connect the car to romraider some values disappear or appear. It updates the list to what the car supports when its connected Link to comment Share on other sites More sharing options...
Scruit Posted February 10, 2012 Author Share Posted February 10, 2012 Ok, here's what I found out. When you start the software before plugging in the cable I can only see about 80% of the counters. If I start romraide with the cable connected already I see more counters. Even disonnecting/reconnecting the ECU doesn't make the missing counters appear. I'm sitting in my car right now, hooked up, creating the logger profile. I'll log another run tomorrow morning. Do you want the 1-byte or 4-bye numbers?

Scruit Posted February 10, 2012 Author Share Posted February 10, 2012 For engine load I see 1byte, 4byte or calculated, all are g/rev units. For throttle plate I see 2byte or 4byte. For Wastegate I see Primary wastegate duty cycle, PWDC max 2byte, PWDC max 4byte (listed twice) Link to comment Share on other sites More sharing options...

bmx045 Posted February 10, 2012 Share Posted February 10, 2012 clean! only 12psi lol Link to comment Share on other sites More sharing options...
Scruit Posted February 10, 2012 Author Share Posted February 10, 2012 Nice, thanks. How do you calculate the psi? Looking for a stock hardware tune for now. I'll start playing with UP and DP setups once my truck car is back on the road (and I have a spare vehicle in case of problems!) Gonna start researching infamous1 and the romraider forums. Thanks for your help! Link to comment Share on other sites More sharing options...
iNVAR Posted February 10, 2012 Share Posted February 10, 2012 1) The more parameters you log, the bigger the gap will be between intervals. Look on the left. You're at 48ms. The new RR has a "fast polling" option up top. Make sure it's checked if you haven't alerady. It'll make the interval a lot smaller. 2) You are logging redundant parameters. The difference between 1-byte, 2-byte, and 4-byte are a matter of precision. The 4-byte parameters are more precise, but take up more bandwidth also, thereby increasing your logging interval. Log the 4-byte ones only for things you need. Manifold Pressure Relative is your boost pressure. I'd log the 4-byte for this. IAM should be logged. Do 4-byte. Primary Wastegate DC should be regular. Throttle Plate I would just do regular. Engine speed regular. Engine load - 4-byte. Mass Air Flow (g/s) regular. The rest, log whatever need based on what you're trying to accomplish.

sanderjesse7 Posted March 6, 2012 Share Posted March 6, 2012 i logged my car and everything seemed fine, my feedback knock correction was all 0, i believe this is ok but i just want to be sure! is this okay? Link to comment Share on other sites More sharing options...
iNVAR Posted March 6, 2012 Share Posted March 6, 2012 Sigh... READ. http://legacygt.com/forums/showthread.php/knock-do-you-have-anyi-97539.html Search! And then after doing all of that, if you still need help, then post up logs AND LV. Link to comment Share on other sites More sharing options...

Mega Users seabass07 Posted March 6, 2012 Mega Users Share Posted March 6, 2012 This is trivial, but I prefer iam 1byte. You don't need it to be precise. If it isn't 1, there's a problem. Actually, I stopped logging it. I just do a LV prior to a run and log only knock sum. I'll log it if I just did a reset though. Also, if you're concerned about resolution, don't worry about maf.
