Need more tables... Please :)

[dmaxfireman]

hey EFI crew, how do we go about requesting maf and map rescaling tables for the lbz and if it matters, os 6128?

trying to work out a few bugs. and secondly any tables to do with the intake air heater available?

thanks!!!

you guys are the best!!:hug:

un hook IAH and turn the codes off.....

yes though it would be nice to just shut that sucker off all the way....

already did that the codes still show up in the background though been trying to figure out a way to fool it with resistors and such but still no luck. now i have a damn maf problem that i can't get rid of...... may have a bad sensor now that i think about it, but recal tables would definitly help!!

What kind of MAF troubles are you having?

 

[dmaxfireman]

keep setting p0101. codes are setting while maf is in "ok" range according to efi live tables compared to mastertech scanner (1 step under tech2) sitting at dealer right now to have buddy of mine confirm. gonna try and get a warranty sensor out of LI for tomorrow am. cross fingers that the twins don't deter them from giving me the sensor under warranty

 

[dmaxfireman]

cleaned sensor earlier and let truck idle and it is setting codes while idling...... not good. not sure exactly how to calibrate the sensor either need some sort of calculation??

 

[dmaxfireman]

c0905-c0908 tables might help. was looking through the lmm os and they have a few more tables than us. wheres the love?!! :angel:

 

[dmaxfireman]

well dealer is giving me a sensor under warranty 8 am tomorrow. hopefully it works!!!! will let everybody know

Ross will add a table for the next release. It turns out that the MAF sensor on the LMM is different to other Dmaxes and the tables we currently have don't work because they are based off the older style sensor.

Go into the MAF Sensor Parameters and make the following changes:

{C0901} P0101 Lower Limit Threshold-0.00
{C0902} P0101 Lower Error Time-655.00
{C0903} P0101 Upper Limit Threshold-105.82
{C0904} P0101 Upper Error Time-655.00

already done that josh. every 15 min code still sets. thats why i think the sensor went bad. sitting in dealer lot right now. buddy is grabbing techII and candi module will update in a few min. thanks cindy and ross!!

 

[dmaxfireman]

damn sensor did not fix it...... anybody know the procedure for testing the maf plug coming from the truck? starting to get pissed...... may get stock air box and mouth piece and hook it up to see if my problem is rooted in the twins. if so oh well gotta deal with the code. if not maybe it will let me find the source.

well, i took a look at an old log i had and compared my maf flow at idle. ( the only constant because i did not have the maf volts pid selected ) and was reading high, by about 20-25%. so i dropped all maf values down by appx 25% and set the error time to 655 seconds. and since have not thrown a code. a temporary fix for now. I want to get it all figured out the right way though.


my theory is that maf sensor actually uses velocity to calculate volume so with a smaller intake tube the velocity is increased to achieve the same volume. so i matched the proper flow to the proper voltage (ie velocity) seems the be working for now. can't wait for the rescaling tables though!!

 

[JoshH]

What size is the intake tube?

 

[dmaxfireman]

iirc stock is 4.5 my new one is 4
