Okay, i've got an issue that i'm sure somebody here can help me solve.
I've talked to lots of people about the proper way to set up a larger turbo upgrade for my vehicle and how to maintain great air/fuel/timing etc...

My plans are a Garret GT30R with of course an upgraded fuel system and ignition system, but have problems knowing and researching the best ways to handle the ECU info.

What i've been told & have figured out is that i have about 4 choices:

1) Run an aftermarket ECU and only put down about 4 more psi than normal and the built in adaptives will be just fine ( i hate this idea, it will give me very little)

2) Run a piggyback computer like a Unichip (aka UTEC for WRX crowd) or S-AFC, this i hear is a fairly good way to go and should cost around 700 for the unit w/ boost controller and another 500 to tune it.

3) run a standalone like a TEC2, but this isn't really something i can afford, 2000 just for the box, and then another 1000 to get it running properly, no thanks.

4) Get a GIAC tuner to open up the software on their program and dyno tune everything in, i talked to Jeremy @ matrixengineering (sponsor of the 1.8T challenge and producer of many great kits and cars in the area) and he said that tuning the Garret software runs about 600 dollars PER HOUR and it would take at least 3 hours to get stuff right.

So basically i'm feeling like i'm fvcked hardcore and need some advice. The reason I post here is because not many people in the volvo crowd have done turbo swaps, and all you know how this goes down.

plus, if i wanted the info i'd have to ask the swedes, and no pa svenska, lol.


THANKS A TON, i hope somebody responds.

I would hit the performance forum with this question, they know much more... and don't often scroll thru this forum's crap...

option 1) is useless, I agree...

option 2).... I would bet you would be spending more than $500 on the unichip tuning... and it is really dependent on the tuner... someone who has experience on your engine would be much better... it is all the same really, but a turner who knows the engine is better.... I think it would be more since it requires dyno time... should be a good setup, but not PERFECT....

option 3) is really the best for performance... but I agree, $$$...

option 4).... hmmmm I would be ready to spend even more...

all out custom tuning is hardcore, and it you are gonna need to spend more than you think or want and you are gonna need another car. Talk to john baas... (xrtic)... he has been working on his custom turbo setup.... tuning is work.

You'll need to run the SAAB APC system on your car. The APC systems on the SAAB 900's (89-93) were a stand-alone computer that listens for engine knock and backs off the boost when detonation is detected. Its a pretty cool system that is plumbed directly to the Waste Gate Actuator.

Note that this does not solve the fuel enrichment problem, for that you'll need a rising rate fuel pressure regulator.
