Title: Timing pulled help Post by: itemonsale on October 24, 2013, 05:50:57 PM I am running a few problems on my 8E0 1.8T , would you please help me !!!!
1. I am getting timing pulled at least -8 degree at different range of RPM , I would like to know if it is weather knock voltage being too high result in timing reduce or it is something else ( air temp vs timing? the reason I bough this up because the temperature get hotter the car have no power ) I don't have the Air Temp vs Timing map ...can someone help me find the map? 2. Seem like I have a map out of boundary cause my ECU to shut off at high RPM while driving, are there anyway I can search for it? Thank you in advance !

Title: Re: Timing pulled help Post by: carsey on October 26, 2013, 04:39:10 PM Need a proper log of just a run in 3rd gear low RPM to redline so can see a good idea whats happening.
Looks rich though.... AFR 9-10 at times and actual boost seems a long way over specified. Title: Re: Timing pulled help Post by: itemonsale on October 27, 2013, 10:41:41 AM Yes sir, I will do that. yeah I should lean it out a bit. I am using a manual boost controller right now so it is not following the PID controller. Thank you again.
Title: Re: Timing pulled help Post by: itemonsale on October 27, 2013, 10:42:38 AM Anyone can help me loop up a map ( Air Temp vs. ignition) please ? I am willing to pay for your time.
Title: Re: Timing pulled help Post by: carsey on October 27, 2013, 06:50:27 PM From the wiki.
IAT effect on requested boost ME7.1 will adjust the specified load limit depending on IATs. As IAT's go up, ME7.1 brings the max boost up a bit so that the driver can't tell that the car is slow in hot weather. It can do this because the stock boost curve is relatively conservative, and there is plenty of headroom. Also, at some point, if IATs go high enough, max specified load is pulled to prevent knock. KFTARX - IAT correction for maximum specified load However, if you are running a lot of boost, and always want maximum performance, there is no point in increasing boost when it is hot, let alone reducing boost when it is cold. Also, as IATs rise, even with a perfectly flat KFTARX and LDIATA (see below), you will see more requested boost because the ECU knows that a higher P/R is required for a given cylinder fill (PV=nRT for you thermodynamics nerds out there). It is unknown if there is a table for that calculation. To compensate, you may want to taper KFTARX across the board as IATs rise to keep your requested boost sane. In particular, be aware that the maximum requested boost is slightly above the maximum MAP reading. Readers who understand PIDs should recognize that really bad things happen when the measured output cannot reach the setpoint... Title: Re: Timing pulled help Post by: itemonsale on October 27, 2013, 07:00:02 PM Thank you for this valuable information. I studied it and realized it pulled alot of timing when IAT is very high. Correct, I am looking for the KFTARX for my 8E0 bin file which I don't have on my XDF file.
Title: Re: Timing pulled help Post by: ddillenger on October 27, 2013, 08:50:47 PM 26C78 is KFTARX, right underneath KFLDHBN.
Title: Re: Timing pulled help Post by: itemonsale on October 28, 2013, 04:16:43 AM MANY THANK YOU to all of you !
Title: Re: Timing pulled help Post by: itemonsale on October 28, 2013, 04:21:04 AM am I correct using these parameter for air temp and specific load
Column - 0x158A7 ( 12 data point ) AIR TEMP Row - 0x13514 ( 12 data point ) LOAD Title: Re: Timing pulled help Post by: itemonsale on October 28, 2013, 04:25:13 AM Ddillenger , can you help me to find kftarxzk too? please ! thank you
Title: Re: Timing pulled help Post by: carsey on October 28, 2013, 06:58:30 AM Straight after KFTARX
Title: Re: Timing pulled help Post by: itemonsale on October 28, 2013, 07:30:52 AM is it suppose to be 10x12 16 bit map with 0.0000031 factor? for bot KFTARX and KFTARXZF
is that suppose to be Air Temp vs. RPM ? Title: Re: Timing pulled help Post by: carsey on October 28, 2013, 07:38:42 AM In the 032 HJ file Im looking at the maps are 12x8 with rpm and IAT temp as the axis. 0.000031 is the factor offset.
Title: Re: Timing pulled help Post by: itemonsale on October 28, 2013, 08:08:32 AM I dial in the Map address 16 bit 12x8 ( 0.000031 factor )and the map doesn't' really look linear ( I haven't' define x and y axis yet)
Title: Re: Timing pulled help Post by: ddillenger on October 28, 2013, 08:27:45 AM KFTARX 10x12 26c78factor 0.000031
KFTARXZK 26d68 KFTARX something or other 26E58 axis temp .75x 19CDE engine speed .25x 13434 But these have nothing to do with timing, they alter maximum specified load based on IAT's. Title: Re: Timing pulled help Post by: itemonsale on October 29, 2013, 11:14:19 AM Thank you everyone...
I got the map dial in... are they all suppose to be around the value of 1 ? .86 .92 1 ? what is the value I am entering? is that percentage of the power output? like .80 = 80%*TQ request? Correct, it has nothing to do with the ignition directly, but since I am running a manual boost controller, if the specified tq over the target output it will have to reduce the power by either retarding timing or reduce boost( in this case only reducing timing) , so I believe it is indirectly affecting it. Title: Re: Timing pulled help Post by: itemonsale on October 29, 2013, 06:20:50 PM Can someone tell me what is the name for " Air Temp Timing Correction " I found it on http://www.eurodyne.ca/forum/viewtopic.php?f=21&t=689.
