volvo 850 t5-r ecu GIAC tune
So I stumbled on a t5-r in the yard so I took the ecu to replace my plain t5 ecu and Little did i know it was tuned! opened the ecu box and found a GAIC chip soldered in.
So i am hoping someone here might have one and have a little insight on what the tune is and info on it.


I called GAIC and it was some new employee who says they haven't supported volvo tuning due to other projects for years.
The t5-r in the yard has a 3 inch exhaust and the GIAC ecu, those are the only upgraded parts. So i would assume its an entry level tune.
I have an exhaust and plenty of other supporting mods. Just trying to get some info on it before I constantly run it.
Anyone have any info!?

Most chipped tunes arent worth it.. but there are some that are worth it.. Although ive never heard of giac, from a look at their site they dont even chip anymore either they flash.
What is it boosting to?
Do you have a wideband?

It boosts to 15 lbs and I have searched the forums and found someone saying the GAIC tunes is the same as a PES tune, whatever that is and that GAIC charged $650 for these ecus. So my guess is its not too bad of a tune considering they tune buggatti veyrons lol but I could be wrong!
An no on the wideband, I need one though!

where is the car located?
It a yellow or black?
It is already stripped our completely totaled?
Could it be salvaged or bought back from the junkyard?
If so how much would it take to get running?
Current mileage?

Defiantly get a wide band, as soon as possible if you are going to run that tune.. alot of earlier tunes especially chips will run very lean... BSR tunes run extremely lean..
where is the car located?
Arizona
It a yellow or black?
Black
It is already stripped our completely totaled?
Haha it's gonna be stripped by me
Could it be salvaged or bought back from the junkyard?
Body is ok but has no r bumper, my guess is its a salvage has no exhaust ecu wheels spoiler rear bench. Shift **** center console...
If so how much would it take to get running?
I don't own it. And probably more than its worth.
Current mileage? 110k

You cant go wrong with a aem
they are fairly cheap on ebay Aem 30 4100 6 in 1 Digital A F Wideband Uego O2 Controller Gauge | eBay
but Ive heard really good things about the PLX
PLX DM-6 SM-AFR | Wideband Air Fuel Gauge
Also check the turbo that was on the donor car, It might have been upgraded

Ok I'll take a look at some widebands.
Yeah I'm going back this weekend to check the turbo and injectors to see if I missed anything.
Thanks a lot for the help!
When I called GAIC they said at minimum the boost map, fuel and timing would have been changed with the chip, so no cheap chip that tricks the ecu into dumping more fuel. So it can't be too bad, it drives real smooth.
