Thanks, John | I will answer this for you. There should be no change in idle since your DME adapts for the best AFR or Lambda during normal driving. The ruff idle is caused by increasing overlap in the camshafts (when both intake and exhaust vales are open at the same time to cause a scavenging effect). Degree your camshafts with lots of overlap and you get more high end power while suffering a lose of low end torque. Anyways simple answer to your question is no Barrie's tune will not cause a ruff idle.

Thanks...John | Nothing in the idle mapping is changed unless you specifically need me to change it for mods but other then that no you will not get a rough idle.

Just one more question, and I'll shut up: Why didn't BMW tune ti's to get the extra hp and torque that your tune wrings out of the engine? Any thoughts?

Thanks, John A. | There are many answers to this question as they are leaving room for real world problems. Bad fuel, Hardware problems, Lower octane, People who don't maintain a engine correctly, warranty's. Not willing to spend much time tuning for peak hp. Different engine loads due to tire size change. This is why you must run the designated octane per the tune or you risk detonation and popping the head gasket. everything in my tune is calculated for more HP and Reliability as long as you run the proper Octane. all the best | | | 12-01-2013, 03:38 AM | #52 | Senior Member Join Date: Dec 2010 Location: Wichita Falls, Texas Posts: 1,364 | I get it now...thanks!

Car has no rear in it at the moment, as soon as the rear running gear is back in I will report. | | | 12-02-2013, 12:11 AM | #54 | Senior Member Join Date: Mar 2010 Location: Ottawa Posts: 579 | Quote: Originally Posted by jca I get it now...thanks!

Do you get roughly the same gains as the m42? I would think the obd2 stuff in the m44 ecu's would be a little more restrictive. __________________ -'98 318ti -'87 VW Scirocco, 2.0 Motronic swap -'95 VW Cabrio | | | 12-06-2013, 03:04 AM | #57 | Senior Member Join Date: Apr 2007 Location: Elizabeth City, NC Posts: 3,877 | I've been running the M44 tune since June 2011. I've put 35k miles on the car in that time and had absolutely no issues related to the dme. I never had the car dyno'd but I remember feeling a nice bump in midrange power. It was definitely a noticeable difference. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM | | | 12-06-2013, 03:44 AM | #58 | Senior Member Join Date: Mar 2010 Location: Ottawa Posts: 579 | Quote: Originally Posted by UberWagen Anybody here running the m44 tune?

I can help you with that too thanks for the good feedback though | | | 12-06-2013, 05:39 AM | #60 | Member Join Date: Dec 2013 Location: Europe Posts: 32 | What kind of power gains are we talking here? Surely there had to have been baseline dyno results posted? I didn't think there was much power to be had out of tuning n/a vehicles | | | | | Currently Active Users Viewing This Thread: 3 (0 members and 3 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
