It was 90 here. He sent me a tune and I was blowing too much black smoke with it. I talked to him and he tweaked it for altitude since I live at 6000+ ft above sea level. No smoke. I will pass the yearly test and put the other back on it and drive around so everyone knows she is an oil burner.

526 EGR/FCV delete tune.


Hey folks,

I'm in the midst of my second EGR/FCV delete. The first Jeep ECU flash went flawlessly but I'm stuck with the second one.

My READ through MPPS turn up: 037377526P53362K4.

I successfully WROTE Greybeast-526-EGR_FCV_Delete-Stock_Tune.

However the Jeep is still throwing P1140 and P0403. I've tried clearing codes several times and driving a few miles.

If anyone has an suggestions I'd love to hear them.

I can built one without DTC

looking for a 516 EGR delete tune. 2006 CRD

First of all thanks to all the interesting and informative contributions in this thread its a really interesting read.

I thought it may be of benefit to me to try a different map or to restore my old map from my dead ecu ( thats how i bought the car with dead ecu ) , for the desired result of better starting with the 5v metal glow plugs, the thought being that i may have older map on the new ecu not updated for the metal glow plugs, the ceramic 7volt ones were still in it when i bought the car last year but number 2 plug had been replaced with a 11v metal one and the actual one that was faulty was still in no 3 because the glowplug loom was in backwards , so i changed all 4 glowplugs to the 5 volt metal ones after tring a set of 7volt metal ones, both starting results were still terrible in cold mornings , like under 10 degrees C.

ok so i got the dongle thing and setup an old laptop with windows 7 just for this with the mpps software and titanium, all good as i was not using it for anything anyway.
As i have just replaced my ECU and i still had the old one which still has problems, so before i messed up anything that was working i plugged in the old ecu because i can still communicate with it , so to test the software and not brick my working ecu, read the rom from the ECU , yep all good , identified that its 809 version , ok all good , downloaded the stock 809 rom from here and upload to the old ecu , all ok and then checked to see that the rom on the ecu had changed , everything was good so i was happy to proceed to the working ecu, having established that it all seems to be working.

Swap the working ECU back into the car , read the rom ( created my backup also is the 809 version ) , then out of interest to see if the stock rom would be any noticeable difference in performance or glow plug cold engine start, i uploaded the said "stock 809" from the first or second post in this thread .

so on going for a drive it was slower off the mark , seemed to have significantly less power , started about the same so didn't help with glow plug cold starting issue at all , but what did happen was odd about 20mins into a drive to pickup some parts the car just had no exceleration at all, put my foot down and nothing it was still going but not accelerating at all never did this on the other rom map, I think there's something wrong with the 809 stock rom posted here ! , i restored my old rom to the ecu and performance instantly was 100% better and acceleration was restored , thought this is kinda weird it was definately the stock 809 map causing issues.

I wonder if anyone that understands titanium would be able to look at my rom from the ecu and see how different it is to the stock 809 rom as it certainly drives different and may be helpful to others that want a better performing rom map.

all i really want to change is the glowplug settings , im pretty happy with the torque but wont complain for small improvements .

So few questions .
1. Have the glow plug voltage and duration locations been identified 100% so they can be changed to increase the time that the glow plugs activate , im running the 5v metal plugs but it starts like doo doo on a cold morning compared to the 7v ceramics that were in it before, I have a 40mhz dual trace oscilloscope i can look to see if there is any difference with, unfortunately its not digital so i cant record ( making it harder ), but perhaps i could see if i can change the voltage or pulse width or duration in the software, and changes to these would give me the result im looking for which is slightly more heat in the plugs at startup.

lastly can you change the VIN number in the ecu with this dongle ? i had to change the , ignition key and the skim and the ECU together to get it working.


thanks .

Hi.
I'm having underboost fault code and it seems that egr is not closing.
So I was looking for egr delete but it seems that 1037375601 SW is not available on first page.
Anyone? Thanks.

I can't think of a reason why they would not work.

The trans functions are controlled by a separate module from the ECM functions.

GDE makes trans tunes, but these are for the Automatic Transmissions.

With manual transmissions, the TCM is located between the ears of the driver. The ability to re-program it varies greatly.

Hi guys!

I have a Jeep Grand Cherokee 2.7CRD (2002- European), I need firmware with disabled EGR and FCV.

In this topic, is there a prepared firmware?

Or will one of you be able to prepare my firmware?

I would really appreciate any help.

P.S.

If anything - sorry!

- I use a translator.

Hello,

I've recently acquired my sisters 2006 Jeep Cherokee 2.8crd, it has the engine management light on (code P0610) and I want to delete the EGR.

MPPS read the following:
1037375602


I tried to write the following file to the ECU but to no avail, I guess 602 and 603 are not compatible?:

Sir Sam's 603 EGR/FCV/P0610 delete - stock, link- https://www.dropbox.com/s/7ohx9puwnux6a ... e.bin?dl=0

Does anyone have a 602 EGR delete file please?

Kind regards,
