Mackpro Posted August 9, 2010 Share Posted August 9, 2010 Thanks men i do apprricate the info and you taking time to help me.I will keep you posted on the progress.I will try another lift pumpMake sure the coolant is shut off to the fuel heater, if it has one. Alot of the Davco fuel filters have built in fuel heaters in them and I had Bigen's truck in the other day and it had hot coolant running through all the time with no shutoff. Just something to look at. Whats the last 6 of your vin#? I can pull up the parts and software levels in the ECM,s. Quote Link to comment Share on other sites More sharing options...

rhasler Posted August 10, 2010 Share Posted August 10, 2010 vin#1m1aa13y54n156276 4mr21084 that's the complete vin numberThat VIN still shows that the VECU datafile is setup for an FRO15210C transmission. If you have changed the transmission you need to have the datafile changed as well. I have run into this changing from a 13 speed T313 to a T318 transmission (they have the same end ratios) even though the parameters for the speedometer fault were removed. Also this is an ASET AC engine, and not an Etech CCRS, which has problems all it's own.VECU software is 1MS364 with datafile 1MS365 (step 9B), EECU software is 1MS368A with datafile 1MS5166P13 (step 3A). If the turbo has been changed it should be a 631GC5176(A,B,C,or D)X. The original turbo should have been a 631GC5171. You need to replace the drain tube on the turbo with part number 681GC544and then have the EECU flashed with 1MS387 software and programmed with a 1MS5183P13 datafile. You will need to contact Mack One Call and have this information changed and set up, you will then need to take it to a dealership and have the modules programmed. Make sure they calibrate the throttle and turbo after programming and enter the EUP cal codes. If you take it back to Beaumont make them do it for free, since they should have checked/changed all of this already! Quote "Mebbe I'm too ugly and stupid to give up!"

Mackpro Posted August 10, 2010 Share Posted August 10, 2010 I don't want to forget ANYBODY it was a team effor THANK'S FJH and MACKPRO68 i would be lost without you'allHope they get it fixed for ya. Yea the ASET engine is a whole different ballgame. I pulled up the warranty file on this truck and on 5/15/06 it did have a 631GC5176CM5 turbo installed, it was orignally had the 5171 series turbo and when you change the turbo to the 5176 series you must update the software. The warranty claim never metioned that they did. I think Rhasler is on to the problem here. Quote Link to comment Share on other sites More sharing options...

I say this cause things changed mid stroke here before any programing was done! There may be other evil things at work here,Be sure they recalibrate the turbo and the throtle pedal And enter the cal codes (read and save customer data.)

fjh Posted August 12, 2010 Share Posted August 12, 2010 Just curious about this statement...how's that work...???A VGT can produce more air than an engine can use efficently.too much air no fuel to go with it!Not that much power in Air!

Rob Posted August 12, 2010 Share Posted August 12, 2010 A VGT can produce more air than an engine can use efficently.too much air no fuel to go with it!Not that much power in Air! Chrysler had a hell of a time with variable vane technology in turbocharging a few years back. Much the same has FJH has mentioned. Injection system can only put so much fuel out.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

rhasler Posted August 14, 2010 Share Posted August 14, 2010 gearbox speed sensor...............I don't know if you guys in Australia were ever graced with the ASET engines. The AC engine, for on highway applications, had all sorts of problems with EGR, mass flow tubes, turbos, and the like. He definetly has some software issues to be sorted out first, but he may have other issues to deal with too. Quote "Mebbe I'm too ugly and stupid to give up!"

lilbit of everything Posted July 11, 2020 Share Posted July 11, 2020 did you ever find your problem? have you checked the intake pressure sensor? This might sound crazy but make sure your coolant level is ok, and that the sensor is working. i have a cxu613, if the coolant level gets low it doesnt give me an engine light or derate code but it will reduce the torque by 40%..... Truck was driving me crazy, and couldnt figure it out, put water in it and Presto it pulled like it was supposed to Quote Link to comment Share on other sites More sharing options...
