Some notes for the first page about Yeti's 811 stage 4 hot tune:

Just got done ready this thread. Wow great info. Thank you everyone for the all the hard work. Can't wait to try this myself. Wish I had more time to really learn all the maps.

The little cd usually comes with a virus from what I hear. I think we all downloaded software. I think there are links further back in this thread on how to find the software.

Did you hear about the guy who was hooked on brake fluid?
He swears he can stop any time.

There wasn't a virus on mine, just had to have a program to unzip the .rar files.

I haven't posted my mileage in a while. I'm still running Yeti's 808 ECU/FCV delete + Mild tune (vers 1.02) - 450Nm ad my last 3 tanks have all been 25+mpg. I had one tank where I played with the turbo pretty much non stop and I still got 23+ mpg.

hey everyone, any new updates? I'm considering getting the weeks101 elbow kit and assume that one of these would be a good fit.

I started over completely, with a newer and smaller "mod" than my others. It was more comprehensive, but smaller changes, except for upping the fuel a little and upping the rail pressure a little in low and mid-range. I drive a 45 mph road 9 miles + 2 miles of stop and go each way to work, and even if I drive with a lead foot I still get between 24 and 25. My last tank included a 90 mile trip on the interstate. I drove a total of 452 miles until the light came on, filled at 470, and it took 18.95 gallons. I can't upload the tune, however, because my laptop has 3 drives, and currently, the non-windows one is installed...

That's 24.7 mpg. This is without the A/C. Now I'm running with the A/C on, and I don't think I"m going to do nearly as well. I have a little under 200 miles on the tank, it'll take me another week or two to finish.

Not bad, what version is this for? The 808 or the 811?

Hi all, just an update on my tuning issues... I was going great, swapping tunes in and out like a pro . Then as I've detailed in an earlier post, it all fell apart when i tried Yeti's tune for my 809.
As you know, it wiped my file, then spat the dummy and corrupted the ecu. The end result: A 2nd-hand ecu (au$800), then another au$560 to have it re-programmed. Then, another visit to the dealership to have some bugs ironed out... altogether $1500 outlaid. Soooo, I'm back to using my GDE eco tune until I pluck up enough courage to experiment again
Now, to make it clear, it was NOT yeti's tune that tripped things up! It was the way I swapped the tunes. Instead of changing back to my original UNENCRYPTED file, then installing Yeti's tune, I tried to swap directly from the ENCRYPTED GDE file to the new tune. From what I gather, there was some unknown/unrecognized file structure left on the ecu, which stopped the new file from writing. Like having the MBR on your computer harddrive corrupted, sometimes, it's non-recoverable. Hence the need for another ecu...
Yeti has indicated to me that the GDE tune may be as good as it gets, but I'd still l like to do it myself Yep! maybe totally bananas!!!

Hola fellow jeep lovers,

First time poster here My current ride is a 2003 Grand Cherokee 2.7 CRD and I am looking at getting it remapped. Well not exactly, I am looking at getting it remapped by a professional tuner, but because I live in a remote area, I am looking at tools that would allow me to read and extract the OEM map from my jeep's ECU and then upload a bespoke map to my ECU via the same tool.

I have looked around a lot and that's how I came across this thread. Now the thing is the 2.7 CRD is a little bit different from other Jeep models, in that the ECM is a Jeep + Mercedes combo unit and to this day and to my knowledge, only a Jeep dealership will be able to make a proper diagnosis. The Jeep doesn't have full OBDII compliance (that came later with the WH/WK powered by the 3.0 V6 CRD Merc engine) and the 2.7 CRD still relies heavily on the DRBIII protocol for diag purposes.

So even though it is listed as being compatible with the tool in the OP (and many other tools available on the internet for that matter), I am still trying to figure if they will indeed work on the 2.7 CRD.

What do you guys think? Could this work on my engine? Are there any 2.7 CRD owners out there that have tried it? Any input would be greatly appreciated

try to see , If the Powergate II can read and write your ECU , is an Alientech programmer

if this tool can flash your ECU , you can contact GDE , that use the same programmer in different version

Sucks.
Bottom line is if you have the GDE tune, convert it back to stock with the GDE tool before attempting any of this?

Hey thanks for chiming in mate. I've already got in touch with GDE and their flash/scan tool is indeed compatible with my engine.

I've looked at the Powergate II from that website you posted mate bloody hell they're flipping expensive. The GDE tool is more affordable (but still a bit at the high end of the spectrum as far as prices are concerned) and I've also found another couple of tuners in the UK that seem to offer the same tool (rebranded as their own).

Do you know if there's a more generic version of that tool, that could be had for cheaper? $$ is a bit of a concern for now and I would rather invest in a good tune than in an overpriced tool if I'm being honest.

works like this:
There are more versions of the Powergate, GDE uses what is more economical, but the mapping is encrypted and can only use them, the one I use costs more, but does not encrypt the files so I can modify the tune with my requires , or get me to to make online from who I want,

Powergate S, S = Slave encrypted .........
Powergate M, M = Master ........ not encrypted

Alright, thanks mate. Didn't really think the encryption job through.

Has anyone looked into where the Glowplug Voltage setting might be within our tunes. It would be nice to be able to change that without a dealer reflash.



Why dont you take a look and see if the ECU in your jeep is in fact a EDC15. If it is then MPPS should work as well as WinOLS or the other applications that are being used here. There are even some VW specific applications designed around the EDC15 that may find the maps for you.

If you can take a look at the ECU and confirm it is an EDC15 then you should be good to go with the MPPS. Even if you cannot confirm the MPPS units are only like 15USD. It may be worth a shot. Just return it when it does not work.

Thanks mass-hole mate, will have a look later. My concern was mainly due to the Jeep not being full OBD2 compliant and still using the DRB-III protocol for most diag jobs...

I believe that the ECUs rely on a different protocol to communicate at the higher level that we are concerned about. In the case of the Liberty CRD(Cherokee) it's ISO 9141-2 which is also used by VW, Mercedes, BMW etc. My guess is that as long as you have an OBDII port to plug into, chances are very high that the MPPS cable will work for you.

i have a question about CEL 1140 - I installed the weeks elbow kit and tuned the ECM with one of Yeti's tunes (FCV &EGR + mild hp) but I'm still getting a P1140 CEL, is there a way to "tune" that code out?

I assumed that the tunes would prevent this code being thrown, but now I'm thinking that these manage the FCV and EGR to not open but don't remove the check engine lights. Not that I'm complaining - the performance this past week has been great.
