Anyone done the TME (through IPD) ECU upgrade to boose the turbo pressure from 8 to 14, and boost horsepower from 208 to 245???
I'm thinking of this tweak, as I understand the motor doesn't know it's been modified until such occasion that you put your foot in it and need the power, like entering an on ramp in front of an 18-wheeler.
Also, anyone have a recommendation on how to do this upgrade, as I understand there are several options. The IPD option requires you to physically send in the ECU unit and they do the reprogramming and ship back to you, which is a royal pain.

Hi.
I did my own version of the modification, utilizing the Wetterauer chipset as a format base. I recommend a dual cat-back exhaust in addition to the mod, however. Check out the IPD website for reasons.
Performance has improved significantly, particularly while passing, but an added benefit has been an improvement in gas mileage from around 24 up to 29. Don't know for sure why, but the exhaust mod might be contributory. I had a speed shop put on an aftermarked dual exhaust, and added a 3-inch id resonator just behind the cat to keep in-car resonance down.
I performed my mod 5 years ago, while my V70 AWD was still under warranty at 15,000 miles on the odometer. I've got over 90,000 miles on the car now, with no oil consumption or any other indication of wear, but note that I always use Mobil 1 synthetic oil and change it at 5000 miles.
Best of luck with your mod.

hi,
sorry ive never had any experience with the mods you describe although i bet it does make it go fast afterwards!
however as a volvo tech you should be aware that ANY mods to your xc90 such as you describe will completely invalidate the warrenty on the whole vehicle, as the ecu would be reprogrammed with aftermarket software this then affects the whole communication network that runs the xc90s electrical system and therefore volvo can argue that this mod could cause problems in other areas of the cars system. check volvos website if you dont believe me but i know for a fact this is true your warrenty would be worthless and trust me you will need it...
even once the cars out of warrenty aftermarket software could cause future problems and can corrupt volvos software database if you need updates in the future.
the mod you metion about the boost increase can be risky for the transmission also especially on the t6 with auto box,it doesnt handle big power very well.
i dont mean to put a damper on anything but as a tech i see the value of warrenty that a new car provides and i would hate to see you invalidate yours.
steve.

Hey, it sounds like you know what you're talking about and I respect that.
Let me toss some gasoline onto the flame here for a minute. There is a note on the IPD site that says this "may" invalidate your warranty, "if" blah blahhhh blahhh. I also understand it's not possible for Volvo to tell if the ECU has been reprogrammed, and you, being a tech, should know if this is true. Also, another site says the mod can be installed and un-installed at will, since their method of reprogramming is a plug in module that does not require the ECU to be taken out and shipped, as IPD requires.
Therefore, I remain VERY interested in your comments, but wanted to toss in some more comments for your consideration.
Sincerely,
Mr. P

FYI only:
If one suspected that any Volvos SW has been changed from original, it would then also have a different PN and any dealers Vadis PC can easily identify any ECUs SW PN. The SW PN is not written on the outside of the ECU, the PC accesses it. One can also check boost with a guage so one can indeed verify IF anyone tampered with OEM specs, it's not rocket science.
Worst case senerio, IF you seriously overboost and blow the engine, Volvo will most likely research the matter to find out why it blew, not just simply replace the engine under warranty w/o questions. Volvo (VCNA, etc) also knows about the existance of all the aftermarket mods that can void warranty and they'd rather not pay for a costly replacement engine that blew, not Volvos fault. The engines also don't normally blow so it would be very suspicious.
Doubling the boost may not cause it blow BUT it is possible and you should be aware of that.

This seems to be the best route to go. No need to go through the incredible hassle of pulling the ECU and shipping it two ways, and waiting three days. Plus, it's reversible, so it can be set back to stock settings.
Check out the attached link, it's got a graphic on what the unit looks like, and a chart showing power ratings across the Volvo line.

Being a Volvo tech, I highly doubt that a simple device, simple proceedure like that can really do what they're saying it will. I suspect that it won't really do anything but lighten your pocketbook.
The only way that I know of to program any '99 on up Volvo ECU is via Vadis with software. Volvo doesn't make it easy for anyone else to just easily reprogram their ECUs.

hi ,
other companies can download aftermarket software into volvo ecu's i have seen it advertised on tuning websites and stuff, but your are right that volvo doesnt make it easy for them and how succesful this software is or how compatible it is with the CAN and MOST networks in a xc90 is doubtful. plus like i said earlier it definitly voids your warrenty, also using vadis the part numbers and version numbers of the software can be read of and compared to what should be in the vehicle ,so volvo would be able to tell.
mods like this are better done 3 years later when out of factory warrenty.
volvo are so against aftermarket software that some dealers now have to have customers sign a disclaimer sheet that basically says that no other company has downloaded software into the vehicle etc.. (as this can corrupt volvos VITAL(software) database) or warrenty will be void,and the dealer not responsible if new volvo software wont download properly into the car, which can be very expensive if a total reload is required.......

Having been a Volvo tech for many years, I have yet to see ONE car or even hear of ONE vehicle anywhere where anyone has actually DLd any other companies SW into a Volvo not using Vadis.
Despite what ANY website claims, have you or anyone else actually seen or heard of this really working?

hi Ben,
no i must admit that despite seeing adverts for aftermarket software that ive never personally seen or heard of a local vehicle having aftermarket software in it. however i dont read this to mean it doesnt exist as there are so many good tuning websites offering this service they cant all be making it up,also why would volvo themselves be so worried if it couldnt be done? and lastly where computers are concerned ANYTHING is possible, i mean if the programmers who worked for companies such as volvo can design the software in the first place them i guess other programmers can do the same.
lets face it vadis is used to retrieve the software from vital then download it from vadis to the car,but the vadis cart itself doesnt actually do anything that a normal pc couldnt be made to do.
steve.
